RESUMEN

BACKGROUND: Acute ankle sprains represent one of the most common traumatic injuries to the musculoskeletal system. Many individuals with these injuries experience unresolved symptoms such as instability and recurrent sprains, leading to chronic ankle instability (CAI), which affects their ability to maintain an active lifestyle. While rehabilitation programs focusing on sensorimotor, neuromuscular, strength and balance training are primary treatments, some patients require surgery when rehabilitation fails. A critical analysis of the patient-reported outcome tools (PROs) used to assess CAI surgical outcomes raises some concerns about their measurement properties in CAI patients, which may ultimately affect the quality of evidence supporting current surgical practice. The aim of this research is to develop and validate a new PRO for the assessment of ankle instability and CAI treatment outcomes, following recent methodological guidelines, with the implicit aim of contributing to the generation of scientifically meaningful evidence for clinical practice in patients with ankle instability. METHODS: Following the COnsensus-based Standards for the selection of Health Measurement Instruments (COSMIN), an Ankle Instability Treatment Index (AITI) will be developed and validated. The process begins with qualitative research based on face‒to‒face interviews with CAI individuals to explore the subjective experience of living with ankle instability. The data from the interviews will be coded following an inductive approach and used to develop the AITI content. The preliminary version of the scale will be refined through an additional round of face‒to‒face interviews with a new set of CAI subjects to define the AITI content coverage, relevance and clarity. Once content validity has been examined, the AITI will be subjected to quantitative analysis of different measurement properties: construct validity, reliability and responsiveness. DISCUSSION: The development of AITI aims to address the limitations of existing instruments for evaluating surgical outcomes in patients with CAI. By incorporating patient input and adhering to contemporary standards for validity and reliability, this tool seeks to provide a reliable and meaningful assessment of treatment effects. TRIAL REGISTRATION: Not applicable.

RESUMEN

BACKGROUND: High ankle sprains are common athletic injuries and can be associated with long-term sequelae. Regardless of operative or nonoperative treatment, there is a paucity of data in the literature about the long-term outcomes of high ankle sprains. HYPOTHESIS: Nonoperative treatment of high ankle sprains utilizing a standardized protocol will result in good long-term outcomes. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients who experienced a high ankle sprain without radiographic diastasis of the syndesmosis were identified from a previous study database and contacted for long-term follow-up. All patients were high school or National Collegiate Athletic Association Division IA athletes at initial injury and were treated nonoperatively with the same standardized protocol. Patients completed a questionnaire that included documentation of any interim ankle injuries, 2 different patient-reported outcome scores, and ankle radiographs to conduct Kellgren-Lawrence scoring for ankle osteoarthritis. RESULTS: In total, 76 cases in 74 patients were identified in the database. A total of 40 patients were successfully contacted, and 31 patients (24 collegiate and 7 high school athletes) with 33 high ankle sprains completed the survey (31/40; 77.5%). The mean age at follow-up was 45 years (range, 34-50 years), with a mean time from injury to follow-up of 25 years. Overall, 93.5% (n = 29) of the respondents were male, and 42% (n = 13) of the respondents reported an ipsilateral ankle injury since their initial injury, with 16% (n = 5) having ankle or Achilles surgery. The mean Patient-Reported Outcomes Measurement Information System-10 score was 53.4 (SD, 8.3; range, 37.4-67.7), PROMIS median (IQR), 54.1 (39.9, 68.3), and the mean Self-reported Foot and Ankle Score score was 42.7 (SD, 5.86). Follow-up ankle radiographs were obtained in 11 (35%) of the respondents; 27% had Kellgren-Lawrence grade >2 osteoarthritis, and 36% had signs of heterotopic ossification on imaging. The mean tibiofibular clear space was 4.5 mm, and the mean tibiofibular overlap was 7.15 mm, with 27% of patients demonstrating some tibiotalar narrowing. CONCLUSION: At long-term follow-up, nonoperative management of high ankle sprains without diastasis on imaging was associated with acceptable patient-reported functional outcomes and low rates of subsequent ankle injuries. There was a high incidence of arthritis, but most cases were not clinically significant. This case series shows the natural history of nonoperatively treated high ankle sprains and may serve as a comparison for different management techniques in the future.

RESUMEN

Ankle fractures account for 10 % of all fractures in adults. The incidence of ankle fractures is rising, particularly as the population ages. Two thirds are isolated malleolar fractures. The most used classifications are anatomical, Weber's and Lauge-Hansen's classifications. The treatment of lateral malleolar fractures may be conservative or surgical, depending on the ankle stability. To test this, a weight-bearing X-ray is required. If this is not possible on the day of trauma, it can be done 7 days later. Conservative treatment consists of a six-week immobilization in a splint or plaster cast, with weight-bearing as tolerated. Surgical treatment is mandatory for unstable fractures.

Les fractures de la cheville représentent 10 % des fractures chez les adultes. Leur incidence est en augmentation, notamment en raison du vieillissement de la population. Les fractures malléolaires isolées en constituent les deux tiers. Les classifications les plus souvent utilisées sont celles anatomiques de Weber et de Lauge-Hansen. Le traitement des fractures de la malléole externe peut être conservateur ou chirurgical, selon la stabilité de la cheville. Pour tester la stabilité, une radiographie en charge est nécessaire. Si ce n'est pas possible le jour de traumatisme, un contrôle à 7 jours peut être organisé. Le traitement conservateur consiste en une immobilisation dans une attelle ou un plâtre en charge totale en fonction des douleurs pour six semaines. Le traitement chirurgical est réservé aux fractures instables.

RESUMEN

INTRODUCTION: Ankle braces can effectively decrease the incidence of recurrent ankle sprain; however, whether the brace can decrease the severity of sprain and its related mechanism during sprain remain unknown. METHODS: Twenty-two patients with functional ankle instability (FAI) (12 males and 10 females) and 16 healthy subjects (8 males and 8 females) were enrolled in this study. All of the subjects walked on a custom-built tilting platform that offered a 30° inversion (IV) to mimic the IV of ankle sprain. We collected the kinematic and surface electromyography data of patients with FAI with or without ankle brace and normal controls 6 times. RESULTS: The FAI without brace group showed significantly higher maximum IV angles and average IV velocities than the control group (P < .001). The FAI with brace group revealed significantly lower maximum IV angles and average IV velocities than the FAI without brace group (P < .001); this group also showed significantly higher maximum external rotation (ER) angle and average ER velocities than the FAI with brace (P < .001) and control (P < .001) groups. The FAI with brace group indicated significantly lower average EMGPrep (P = .047), EMGTilt (P = .037), and EMGafterTilt (P = .004) of the peroneus longus than the FAI without brace group. CONCLUSIONS: The ankle brace could effectively decrease IV angles and their velocities and increase ER angles and their corresponding velocities during ankle sprain in patients with FAI. It could also decrease the activity of the peroneus longus muscle during ankle sprain.

RESUMEN

BACKGROUND: The aim of study was to observe the therapeutic effect of joint mobilization of Maitland on subjects with chronic ankle instability (CAI). METHODS: 76 subjects with CAI were recruited for this randomized, single-blinded trial and randomized divided into experimental group (EG) and control group (CG). The CG was received conventional rehabilitation, and the EG added 8-weeks treatment of Maitland technology based on the CG. The visual analogue scale, ankle range of motion, Y-balance test, and Foot and Ankle Ability Measure scores (the daily living part of Foot and Ankle Ability Measure scores and the sport part of Foot and Ankle Ability Measure scores) were measured before and 8 weeks after the intervention respectively. RESULTS: There was no significant difference on outcomes between the 2 groups before treatment (P > .05). After 8 weeks of intervention, the visual analogue scale, ankle range of motion (dorsiflexion, plantar flexion, and varus), the value of Y-balance test (forward extension distance, inner extension distance, and posterior extension distance), the daily living part of Foot and Ankle Ability Measure scores, and the sport part of Foot and Ankle Ability Measure scores of the 2 groups were significantly improved (P < .01), and the improvement of the EG showed remarkable than CG (P < .01). CONCLUSION: Maitland therapy is effective in the treatment of CAI. Conventional rehabilitation assisted by Maitland therapy were beneficial to improve pain and functional state in patients with CAI than only routine rehabilitation.

RESUMEN

OBJECTIVE: To explore and compare the dosage of balance training on ankle function and dynamic balance ability in patients with chronic ankle instability (CAI). METHODS: The PubMed, Embase, Web of Science, Medline, and Cochrane databases were searched up to December 2023. Quality assessment was carried out using the risk-of-bias guidelines of the Cochrane Collaboration, and the standardized mean differences (SMD) or mean differences (MD) for each outcome were compute. RESULTS: Among 20 eligible studies, including 682 participants were analyzed in this meta-analysis. The results of the meta-analysis demonstrated that balance training was effective in enhancing ankle function with self-functional scores (SMD = 1.02; 95% CI, 0.61 to 1.43; p < 0.00001; I2 = 72%) and variables associated with the ability of dynamic balance such as SEBT-A (MD = 5.88; 95% CI, 3.37 to 8.40; p < 0.00001; I2 = 84%), SEBT-PM (MD = 5.47; 95% CI, 3.40 to 7.54; p < 0.00001; I2 = 61%), and SEBT-PL (MD = 6.04; 95% CI, 3.30 to 8.79; p < 0.0001; I2 = 79%) of CAI patients. Meta-regression indicated that the intervention time might be the principal cause of heterogeneity (p = 0.046) in self-functional scores. In subgroup analyses of self-functional score across intervention types, among the intervention time, more than 20 min and less than 30 min had the most favorable effect (MD = 1.21, 95% CI: 0.96 to 1.46, p < 0.00001, I2 = 55%); among the intervention period, 4 weeks (MD = 0.84, 95% CI: 0.50 to 1.19, p < 0.00001, I2 = 78%) and 6 weeks (MD = 1.21, 95% CI: 0.91 to 1.51, p < 0.00001, I2 = 71%) had significant effects; among the intervention frequency, 3 times (MD = 1.14, 95% CI: 0.89 to 1.38), p < 0.00001, I2 = 57%) had significant effects. Secondly, in subgroup analyses of SEBT across intervention types, a 4-week and 6-week intervention with balance training 3 times a week for 20-30 min is the optimal combination of interventions to improve SEBT (dynamic balance) in patients with chronic ankle instability. CONCLUSION: Balance training proves beneficial for ankle function in patients with CAI. Intervention time constitutes a major factor influencing self-function in patients with CAI. It is recommended that the optimal dosage of balance training for CAI involves intervention three times a week, lasting for 20 to 30 min over a period of 4 to 6 weeks for superior rehabilitation.

RESUMEN

This study aimed to compare the findings of plain radiography and computed tomography (CT) of foot and ankle in patients submitted to the emergency department with high-energy foot and ankle trauma, to demonstrate if missing fractures on plain radiographs will significantly alter the treatment plan considered for each patient based on the findings of each imaging modality. We retrospectively observed standard radiological foot and ankle x-rays and CT scans in patients who presented to our center from April 2019 to June 2020 with a history of foot and ankle trauma with either loss of consciousness, a history of high-energy trauma, or clinical presentation disproportionate to plain radiographic findings. We investigated the number of fractures of each bone detected on plain radiographs and CT scans and the treatments based on each modality's findings in patients admitted to our center. Sixty-five out of 163 (39.87%) included in our study had at least one missed fracture on plain radiography that was detected on CT. Thirty-one (19%) patients had normal radiography despite actually having fractures. In 38 (23.31%) patients CT changed the treatment plan decided by our surgeons (P < 0.001). The two imaging modalities had a moderate agreement for detecting foot and ankle fractures overall (κ = 0.432). The failure to detect fractures in patients with high-energy trauma can significantly impact treatment effectiveness. Integrating CT scans into the diagnostic process can lead to changes in treatment planning and ultimately improve patient outcomes. LEVEL OF CLINICAL EVIDENCE: IV.

RESUMEN

Post-traumatic osteoarthritis (PTOA) occurs following injury to joints. It accounts for approximately 12% of osteoarthritis and has far-reaching effects on individual patients and social/health care systems. Present work focuses on evaluating the role of the post-traumatic inflammatory response in the development and progression of the disease. As there is minimal evidence to suggest the capacity of cartilage to undergo self-healing, most of this work focuses strictly on the avoidance or prevention of PTOA as opposed to treatment solutions following its onset. Ongoing and future investigations may reveal therapeutic targets for possible intervention and ultimately the prophylaxis of PTOA development.

RESUMEN

Background and Objectives: Repetitive ankle sprains lead to mechanical instability of the ankle. Patients with chronic ankle instability may experience decreased muscle strength and limited postural control. This study investigated the effects of a hip-strengthening exercise program on muscle strength, balance, and function in patients with chronic ankle instability. Materials and Methods: A total of 30 patients participated in the study and were randomly assigned to the two groups. Among the 30 participants, 14 were assigned to the hip joint-strengthening exercise group and 16 to the control group. The experimental group underwent a hip-strengthening exercise program and received training for 40 min per session twice a week for four weeks. The control group received the same frequency, duration, and number of sessions. Measurements were performed before and after the training period to assess changes in hip strength, balance, and function. Results: In the within-group and between-group comparisons, both groups showed significant differences in hip joint strength, static balance, dynamic balance, and function (FAAM; foot and ankle ability measures) (p < 0.05). Statistically significant differences were observed in the time × group interaction effects among the hip abductors and external rotation in hip joint strength, path length in static balance, posterolateral and posteromedial in dynamic balance, and FAAM-ADL and FAAM-SPORT functions (p < 0.05). Conclusions: Accordingly, this study confirmed that hip joint-strengthening exercises have a positive effect on the strength, balance, and function of patients with chronic ankle instability, and we believe that hip joint-strengthening exercises will be recommended as an effective intervention method for patients suffering from chronic ankle instability.

RESUMEN

Pseudoaneurysm of the lateral perforating branch of the peroneal artery is exceedingly rare. To our knowledge, eight cases are described in the current literature, with five occurring as a result of trauma and the remainder being iatrogenic. We present a pseudoaneurysm of the lateral perforating peroneal artery in a professional athlete following an inversion-plantarflexion injury of the ankle. He described persistent pain and fluctuant swelling to the lateral aspect of the right ankle with sudden onset of increased pain and swelling 10 days after the initial injury. Arterial duplex identified a pseudoaneurysm of the right lateral perforating peroneal artery. Endovascular coil embolisation of the aneurysm resulted in almost immediate improvement in symptoms. The patient has since regained full function of the affected ankle. This case report highlights the necessity for clinicians to maintain a high index of suspicion in order to promptly investigate and appropriately manage this pathology.

RESUMEN

CLINICAL SCENARIO: Ankle sprains are one of the most common injuries in athletics, and many lead to recurrent sprains, chronic ankle instability, and persistent symptoms. Treatment improvements are needed. Platelet-rich plasma (PRP) involves formulating autologous plasma with higher platelet concentration to be injected in the desired tissue. There is currently high-quality evidence supporting the use of PRP with lateral epicondylitis and knee osteoarthritis to accelerate the healing process and decrease pain. CLINICAL QUESTION: Does the injection of PRP relieve pain faster and improve function compared with no injection or placebo in patients with a lateral ankle sprain? SUMMARY OF KEY FINDINGS: A computerized search yielded 191 studies; of these, 3 studies fit the inclusion and exclusion criteria. PRP injection reduces pain and increases function after lateral ankle sprain 5 to 8 weeks after intervention. CLINICAL BOTTOM LINE: The use of PRP after lateral ankle sprain to decrease pain and increase function is supported with moderate evidence. STRENGTH OF RECOMMENDATION: Based on the Strength of Recommendation Taxonomy, evidence from the included studies is considered as level B, reflecting limited quality patient-oriented evidence.

RESUMEN

INTRODUCTION: Ankle sprains are the second most common sports injury after knee injuries, with about 85% of them affecting the lateral ankle ligaments. These injuries are particularly prevalent in sports like basketball and volleyball. PURPOSE: To investigate the effect of Aquatic therapy as an early rehabilitation protocol for elite athletes with acute lateral ankle sprain grade III on back-to-sport time, dynamic balance, pain, Athletic performance, and muscle power compared to land-based exercise training. METHODS: Thirty elite athletes have ankle sprain grade III with sprain onset from 1 to 7 days, their age ranges from 18-30 years old were recruited. All participants are professional athletes; mainly participating in above-head sports such as volleyball and basketball. The patients were randomly allocated into two treatment groups: Group I (control group): 15 patients received a conventional physical therapy program of structured therapeutic exercise program, manual therapy and land-based exercises, in addition to external support, and Group II (Aquatic therapy group): 15 patients received aquatic training. Visual Analog Scale (VAS) was used to measure the pain intensity, while the dynamic balance was measured by the Star Excursion Balance Test. Athletic performance was measured by HOP Tests (Single, Triple, 6-m, and Cross-over hops) aided by the Agility T-Test (ATT) and Illinois Agility Test (IAT). Muscle power was tested by a Single Leg Press. Finally, back to sports time was recorded for each participant in both groups. RESULTS: There was a significant interaction effect of Aquatic therapy and time for VAS (p < 0.001), single hop (p < 0.001), triple hop (p < 0.001), cross-over hop (p < 0.001), IAT (p = 0.019) and ATT (p < 0.001) of both affected and nonaffected. There was no significant interaction effect of Aquatic therapy and time for 6-MHT of affected (p = 0.923), and nonaffected (p = 0.140). There was a significant main effect of time for all dependent variables (p < 0.001) except for 6-MHT of affected (p = 0.939), nonaffected (p = 0.109), and IAT (p = 0.099). The Star excursion dynamic balance test (SEBT) and Single leg press revealed a significant difference between groups on affected and non-affected sides (p < 0.001*). Lastly and most importantly the back-to-sport time revealed a significant difference in the return-to-sport time in favor of the Aquatic therapy group who returned faster than the control group (p < 0.001*). CONCLUSION: Aquatic therapy is more effective than traditional protocols regarding early rehabilitation of acute ankle sprain grade III in Elite professional athletes for reducing pain intensity, improving dynamic balance and athletic performance and power and accelerating their return to sports time. Because aquatic therapy produces better outcomes, it is advised to be included in the rehabilitation programs of athletic patients with acute ankle sprains grade III.

RESUMEN

BACKGROUND: Acute ankle injuries are commonly seen in emergency rooms, with significant social impact and potentially devastating consequences. While several clinical practice guidelines (CPGs) related to ankle injuries have been developed by various organizations, there is a lack of critical appraisal of them. The purpose of this systematic review is to identify and critically appraise evidence-based clinical practice guidelines (EB-CPGs) related to acute ankle injuries in adults. METHOD: We conducted searches in the Cochrane Library, MEDLINE, EMBASE databases, WHO, and reviewed 98 worldwide orthopedic association websites up until early 2023. Two authors independently applied the inclusion and exclusion criteria, and each evidence-based clinical practice guideline (EB-CPG) underwent independent critical appraisal of its content by all four authors using the Appraisal of Guidelines for REsearch and Evaluation (AGREE II) instrument. AGREE II scores for each domain were then calculated. RESULTS: This review included five evidence-based clinical practice guidelines. The mean scores for all six domains were as follows: Scope and Purpose (87.8%), Stakeholder Involvement (69.2%), Rigour of Development (72.5%), Clarity of Presentation (86.9%), Applicability (45.6%), and Editorial Independence (53.3%). CONCLUSION: The number of EB-CPGs related to ankle injuries are limited and the overall quality of the existing evidence-based clinical practice guidelines (EB-CPGs) for ankle injuries is not strong, with three of them being outdated. However, valuable guidance related to Ottawa rules, manual therapy, cryotherapy, functional supports, early ambulation, and rehabilitation has been highlighted. Challenges remain in areas such as monitoring and/or auditing criteria, consideration of the target population's views and preferences, and ensuring editorial independence. Future guidelines should prioritize improvements in these domains to enhance the quality and relevance of ankle injury management. SYSTEMATIC REVIEW: Systematic review.

RESUMEN

PURPOSE: The aim of this study was to compare the clinical outcomes between patients with chronic ankle instability (CAI) undergoing arthroscopic anterior talofibular ligament (ATFL) repair who received elastic bandage treatment and those who received lower-leg cast immobilization. METHODS: CAI patients with isolated ATFL injury undergoing arthroscopic ATFL repair from January 2017 and August 2019 were included in the study. The visual analogue scale (VAS) at rest and during activities, American Orthopedic Foot and Ankle Society (AOFAS) score, Karlsson Ankle Functional Score (Karlsson score), and time of returning to walk, walk normally, work and sports were evaluated preoperatively, and at 6 months and 12 months follow-up. RESULTS: A total of 41 patients were included in this study. Among them, 24 patients accepted lower-leg cast fixation, and the other 17 patients were immobilized with elastic bandage. Compared to patients with lower-leg immobilization, patients with elastic bandage fixation had significantly lower VAS during activities (P = 0.021) and higher AOFAS score (P = 0.015) at 12 months follow-up. The Karlsson score at 6 months follow-up were significantly higher in elastic bandage group than those in lower-leg group (P = 0.011). However, no significant difference was observed in time of returning to walk, work and sports between the two groups. CONCLUSION: Elastic bandage treatment was better than lower-leg cast immobilization in terms of eliminating pain symptom at 12 months follow-up, and improving ankle functional outcome at 6 months follow-up. Moreover, the present study emphasized that lower-leg cast immobilization offered no advantages in arthroscopic ATFL repair postoperative immobilization. STUDY DESIGN: Cohort study; Level of evidence, 3.

RESUMEN

PURPOSE: A lateral ankle sprain is the most common musculoskeletal injury in the physically active population. However, it is unclear how the clinical condition evolves during the period after the injury and what proportion of patients develops chronic symptoms. Therefore, the purpose of this study is to assess the evolution of patient-reported outcome measures after a first time lateral ankle sprain. METHODS: A prospective clinical study assessed the patient-reported outcome measures (PROMs) of a consecutive group of 100 patients during 1 year after a first lateral ankle sprain. The Karlsson score and Foot and Ankle Outcome Score (FAOS) were assessed at 6 weeks, 3 months, 6 months, 9 months and 1 year. The Cumberland Ankle Instability Tool (CAIT)-score was assessed at 6 months, 9 months and 1 year. The difference between the time points of all scores was analysed using the positive change over time (binomial test versus 50%) and the difference in score (signed rank test). The time to sustained excellent level was also assessed overall and in several subgroups: age, gender, degree of injury (2 or 3), avulsion fracture, use of crutches, use of cast. Differences between subgroups were assessed by a generalized log-rank test. RESULTS: All clinical scores demonstrated an improvement up to 12 months after the sprain. The median Karlsson score (interquartile range) improved from 62 (50-80) at 6 weeks to 90 (72-100) at 3 months, to 97 (82-100) at 6 months to 100 (90-100) at 9 months, to 100 (100-100) at 1 year. The analysis of positive change over time demonstrated a significant positive change (P-value <.0005) between all time points except between 6 weeks and 12 weeks when using the FAOS quality score. The difference in score demonstrated a significant change (P-value <.01) between all time points except between 36 weeks and 48 weeks when using the FAOS pain and FAOS sports score. Age and presence of an avulsion fracture were correlated with a slower recovery and worse results. At 1 year, in total 13 patients (13%) had a worse outcome corresponding to a Karlsson score < 81 or CAIT score < 24. CONCLUSION: The clinical condition after a first ankle sprain demonstrated a significant improvement in PROMs between the different time points in the first year. Twelve months after a first lateral ankle sprain 13% had a fair or poor outcome. Higher age and presence of an avulsion fracture were correlated with a slower recovery and worse results. This information is useful in clinical practice to predict further progression and inform patients. Moreover, it is valuable to improve treatment strategies. LEVEL OF EVIDENCE: Level II (prospective cohort study).

RESUMEN

RATIONALE: Maisonneuve fracture is a specific type of severe ankle injury. To our current knowledge, once a Maisonneuve fracture is diagnosed, the surgery is always recommended for fear of sequelae from inaccurate joint reconstruction. However, in this case, we treated a Maisonneuve fracture with a short leg cast, and the 41-month follow-up showed a favorable outcome with no post-traumatic osteoarthritis, chronic pain, and instability. Therefore, this case provides evidence for the feasibility of conservative treatment of Maisonneuve fracture. PATIENT CONCERNS: A female patient in her early twenties sprained her left ankle while running, suffering regional pain, swelling, and limited mobility. DIAGNOSES: We diagnosed a Maisonneuve fracture with superior fibular fracture and Volkmann tuberosity fracture, a slight separation of inferior tibiofibular syndesmosis (ITS). INTERVENTIONS: The patient rejected our surgical recommendations in favor of nonsurgical treatment, in addition to refusing immobilization of the knee. Consequently, we had to treat her with a short leg cast for 8 weeks and asked her to return for regular follow-up visits. OUTCOMES: At the final follow-up, the radiography showed complete healing of proximal fibula fracture. The patient reported no discernible subjective differences between her bilateral ankles. The range of motion of the left ankle was measured at 22° of dorsiflexion and 40° of plantarflexion. Functional assessments using Olerud-Molander ankle scale and American Orthopedic Foot and Ankle Society Ankle-Hindfoot scale both scored 100 points. Additionally, the radiographic assessment classified arthritis as stage 0 according to Morrey-Wiedeman classification. LESSONS: To avoid missing and misdiagnosing, the physical examination should always extend to 2 neighboring joints. Secondly, if a Maisonneuve fracture is suspected, further computed tomography scans, radiography, and magnetic resonance imaging can help to determine the stability of the ITS and the integrity of the lateral collateral ligaments before making therapeutic decisions. Finally, considering the lateral collateral ligaments may remain intact, we recommend stabilizing ITS by repairing the medial ligaments, which can be conducted arthroscopically and be more minimally invasive, providing an elastic fixation that aligns better with the biomechanics of the ITS which is characterized as a micro-mobile rather than fully fixed joint.

RESUMEN

BACKGROUND: Despite the high incidence of ankle sprains, the ideal treatment is controversial and a significant percentage of patients who have suffered an ankle sprain never fully recover. Even professional athletes are affected by this post-traumatic complication. There is strong evidence that permanent impairment after an ankle injury is often due to an inadequate rehabilitation and training program and too early return to sport. THERAPY AND REHABILITATION: Therefore, athletes should start a criteria-based rehabilitation after ankle sprain and gradually progress through the programmed activities, including e.g. cryotherapy, edema reduction, optimal load management, range of motion exercises to improve ankle dorsiflexion and digital guidance, stretching of the triceps surae with isometric exercises and strengthening of the peroneus muscles, balance and proprioception training, and bracing/taping. The fact that this is professional sport does not exempt it from consistent, stage-appropriate treatment and a cautious increase in load. However, there are a number of measures and tools that can be used in the intensive care of athletes to improve treatment and results.

RESUMEN

Pediatric foot and ankle trauma includes a range of injuries affecting the lower extremities in children, typically aged from infancy to adolescence. These incidents can arise from various causes, including sports-related accidents, falls, and high-velocity injuries. Due to the dynamic growth and development of bones and soft tissues in pediatric patients, managing these injuries requires specialized knowledge and care. Early diagnosis and appropriate treatment are crucial to ensure optimal recovery and prevent potential long-term consequences. Treatment depends on severity and type of injury but may involve a combination of immobilization, physical therapy, or surgical intervention.

RESUMEN

BACKGROUND Micro-needle knife (MNK) therapy releases the superficial fascia to alleviate pain and improve joint function in patients with acute ankle sprains (AAS). We aimed to evaluate the efficacy and safety of MNK therapy vs that of acupuncture. MATERIAL AND METHODS This blinded assessor, randomized controlled trial allocated 80 patients with AAS to 2 parallel groups in a 1: 1 ratio. The experimental group received MNK therapy; the control group underwent conventional acupuncture treatment at specified acupoints. Clinical efficacy differences between the 2 groups before (time-point 1 [TP1]) and after treatment (TP2) were evaluated using the visual analogue scale (VAS) and Kofoed ankle score. Safety records and evaluations of adverse events were documented. One-month follow-up after treatment (TP3) was conducted to assess the intervention scheme's reliability. RESULTS VAS and Kofoed ankle scores significantly improved in both groups. No patients dropped due to adverse events. At TP1, there were no significant differences between the 2 groups in terms of VAS and Kofoed scores (P>0.05). However, at TP2, efficacy of MNK therapy in releasing the superficial fascia was significantly superior to that of acupuncture treatment (P<0.001). At TP3, no significant differences in scores existed between the groups (P>0.05). CONCLUSIONS This study demonstrates that 6 sessions of MNK therapy to release the superficial fascia safely and effectively alleviated pain and enhanced ankle joint function in patients with AAS, surpassing the efficacy of conventional acupuncture treatment. Future studies should increase the sample size and introduce additional control groups to further validate the superior clinical efficacy of this intervention.

RESUMEN

BACKGROUND: Ankle sprains are one of the most frequent injuries of the musculoskeletal system. The injury pattern determines the treatment and are crucial for the outcome. Nonoperative treatment is commonly recommended for isolated injuries of the lateral ligaments but no standard strategy exists in combined ankle ligament injuries. The goal of this national survey was to achieve an overview about the current diagnostic strategies and common treatment concepts in Germany. MATERIAL AND METHODS: All members of the German Society for Orthopaedics and Trauma Surgery (DGOU) were invited to participate in an anonymous survey about the diagnostic and therapeutic approach in cases of ankle sprains. The online survey consisted of 20 questions. Besides questions about the speciality and scope of activities the participants were ask to depict their diagnostic and therapeutic strategy. RESULTS: A total of 806 participants completed the survey. Most of them were orthopedic trauma surgeons and worked in a hospital. During the first presentation the anterior drawer test (89.5%) and the inversion/eversion test (81.6%) were most commonly used, 88.1% always make an X­ray examination and 26.5% an ultrasonography examination. Isolated injuries of the anterior fibulotalar ligament (LFTA) were treated nonoperatively by 99.7% of the participants, 78.8% recommend full weight bearing in an orthesis, 78.8% treat the complete rupture of the lateral ligaments without operation whereas 30.1% stated that they would treat a combined lateral ligaments rupture with an injury of the syndesmosis nonoperatively. DISCUSSION: Due to the heterogeneity of injury patterns after ankle sprain no consistent recommendations for diagnostics and treatment exist. The Ottawa ankle rules and ultrasonography were not often utilized despite of the good evidence. The isolated rupture of the LFTA is diagnosed and treated according to the national guidelines by most of the participants. In cases of combined injuries of the lateral and medial ankle ligaments the majority choose a nonoperative treatment strategy which is justified by the guidelines with a low level of evidence. Combined injuries of the syndesmosis and the lateral ankle ligaments were treated operatively, which also correlates with the recommendations in the literature. The standard care of ankle sprain in Germany is in accordance with the recommendations from the current literature.
