RESUMEN
INTRODUCTION: We compared fixed and articulated ankle-foot orthoses (AFOs) in home-based mobility tasks to assess short-term mobility, dynamic balance, quality of life, anxiety/depression, disability level, stroke severity, autonomy, human functioning, and patient satisfaction. METHODS: This was a two-arm, parallel-group, randomized controlled trial with concealed allocation, assessor blinding, and a complete case analysis involving patients with chronic stroke. The participants were randomized into two groups: fixed (n = 24) and articulated (n = 23) AFOs. The AFOs were custom-fabricated, and both groups performed four-week home-based mobility tasks five days weekly. Primary outcome measures included changes in balance and mobility assessed using the Tinetti Performance-Oriented Mobility Assessment (POMA), Timed Up and Go (TUG) test, and Functional Ambulation Category (FAC). Secondary outcomes included quality of life, anxiety/depression, disability, stroke severity, autonomy, human functioning, and patient satisfaction. RESULTS: In a between-group comparison, after adjusting for age, sex, stroke severity, and thrombolysis, the articulated AFO group showed better performance in the TUG test (p = 0.020; d = 0.93), POMA-Gait (p = 0.001; d = 0.53), POMA-Total (p = 0.048; d = 0.98), and FAC (p = 0.003; d = 1.03) than the fixed AFO group. Moreover, significant difference was noted in human functioning (moving around using equipment)between the groups (p = 0.047; d = 92). CONCLUSION: A program involving home-based mobility tasks and articulated AFOs improved functional mobility after stroke.
RESUMEN
The increase in competitive sports practice among children and lack of ionizing radiation have resulted in a higher demand for MRI examinations. MRI of the children skeleton has some particularities that can lead orthopedists, pediatricians, and radiologists to diagnostic errors. The foot and ankle have several bones with abundant radiolucent and high signal intensity cartilage in several ossification centers, apophysis and physis, that can make this interpretation even harder. The present revision aims to show, how to differentiate between normal developmental findings and anatomic variants from pathologic conditions, whether mechanical, inflammatory, infectious, or neoplastic.

BACKGROUND: Lower limb coronal alignment was thought to be a predictive factor for Unicompartmental Knee Arthroplasty (UKA) result. The tibial bony resection and implant position lead to joint line change postoperatively. Analysis was done to find out the correlation between these factors. METHODS: From 2019 to 2021, 90 medial Oxford UKA were implanted by a single surgeon. Hip Knee Ankle Angle (HKAA), Lateral Distal Femoral Angle (LDFA), Medial Proximal Tibial Angle (MPTA), and intraoperative bony resection thickness were measured. The medial joint line change was calculated. The correlation between joint line change and alignment change was evaluated. RESULTS: The mean tibial resection thickness was 4.3 mm. The mean tibial joint line was elevated by 2.3 mm, while the mean femoral joint line proximalized by 0.8 mm. HKAA changed from 8.4° varus preoperatively to 3.6° varus postoperatively. LDFA changed from 89.0° to 86.7°. MPTA changed from 85.6° to 86.6°. Preoperative HKAA showed a strong correlation with postoperative HKAA (p < 0.001), and preoperative MPTA showed a positive correlation with postoperative HKAA (p < 0.001). While preoperative LDFA had a negative correlation with postoperative HKAA (p < 0.001). The femoral joint line change and LDFA change had a significant correlation with HKAA change (p < 0.05). CONCLUSION: The change of joint line had no correlation with postoperative HKAA in Oxford UKA. Preoperative HKAA strongly correlated with postoperative HKAA; while preoperative smaller LDFA and larger MPTA had a moderate correlation with postoperative HKAA. The femoral joint line change and LDFA change had a weak to moderate correlation with HKAA change.

INTRODUCTION: Cardiovascular disease represents the foremost cause of death among chronic and non-transmissible diseases. Diagnostic tools commonly used for peripheral and carotid atherosclerosis, such as ankle-brachial index (ABI) and carotid ultrasonography (CU), may contribute as surrogates for the diagnosis of coronary arterial disease (CAD). MATERIAL AND METHODS: We report a cross-sectional study of 50 patients referred to elective invasive coronary angiography (ICA). Patients were submitted to ABI and CU-for carotid intima-media thickness (CIMT) and carotid atherosclerotic plaque screening (CAPS). Clinical and demographic variables were also evaluated. CAD was defined as greater than 50% stenosis in at least one coronary artery. RESULTS: In logistic regression analysis, only CAPS showed a statistically significant area under the curve (AUC) for CAD prediction: 0.812 (95% CI, p <0.001). ABI and CIMT did not show statistically significant performance. For multivariate logistic regression analysis, the model including variables "gender," "dyslipidemia," "smoking," "pack-years," and CAPS predicted CAD better. The AUC for this model was 0.912 (95% CI, p = 0.002). CONCLUSION: The screening for carotid atherosclerotic plaques may enhance traditional risk stratification strategies for CAD. Longitudinal studies and bigger samples of subject are needed to allow extrapolation of our findings.
RESUMEN
Besides the acute injury and trauma-induced macroscopic alterations, the evolution to posttraumatic ankle osteoarthritis (PTOA) is a complex process progressing at the tissue and molecular level. Furthermore, changes in the molecular pathways affect chondrocyte viability. Treatment modalities for PTOA focal or confined disease include innovative techniques. OBJECTIVE: Our purpose is to increase medical awareness based on scientific evidence of pathophysiology, molecular biology, and treatment of post-traumatic ankle osteoarthritis. METHODS: To support the perspectives of the experts, evidence from the scientific literature respected the PRISMA guidelines and the PICOS search strategy was used. We included case-control, cohort, experimental studies and case reports, written in English. RESULTS: The authors were homogeneously exposed to 282 selected abstracts and 114 full articles directly related to post-traumatic osteoarthritis after malleolar fractures. CONCLUSION: The pathophysiological factors involved in posttraumatic ankle osteoarthritis, such as biological, structural, mechanical, and molecular changes must be studied together, as the interaction between these factors determines the risk of progression of PTOA. Inhibition of a single catabolic molecule or cascade probably is not sufficient to alter the natural progression of the pathological process. Evidence level V, expert opinion.
A evolução para a osteoartrite pós-traumática do tornozelo (PTOA) a partir da lesão aguda e das alterações macroscópicas induzidas pelo trauma é um processo complexo, que progride em nível tecidual e molecular. Além disso, as alterações nas vias moleculares afetam a viabilidade dos condrócitos. As modalidades focais ou confinadas de tratamento para PTOA incluem técnicas inovadoras. Objetivo: Nosso objetivo é aumentar a conscientização médica, com base em evidências científicas de fisiopatologia, biologia molecular e tratamento da osteoartrite pós-traumática do tornozelo. Métodos: Para o embasamento das perspectivas dos autores experts, as evidências da literatura científica respeitaram as diretrizes Prisma e a estratégia de busca Picos foi empregada. Incluímos estudos de caso-controle, de coorte, experimentais e relatos de caso, escritos em inglês. Resultados: Os autores foram expostos de forma homogênea a 282 resumos e 114 artigos completos, diretamente relacionados à osteoartrite pós-traumática após fraturas maleolares. Conclusão: Os fatores fisiopatológicos envolvidos na osteoartrite pós-traumática do tornozelo, como alterações biológicas, estruturais, mecânicas e moleculares, devem ser estudados em conjunto, pois a interação entre esses fatores determina o risco de progressão da PTOA. A inibição de uma única molécula catabólica ou cascata provavelmente não é suficiente para alterar a progressão natural do processo patológico. Nível de evidência V, opinião do especialista.
RESUMEN
BACKGROUND: Flexible cavovarus deformity is prevalent and the Coleman block test is frequently used to assess the first ray plantarflexion malpositioning in the overall deformity as well as the flexibility of the hindfoot. The objective was to assess and compare the weightbearing computed tomography (WBCT) 3-dimensional (3D) changes in clinical and bone alignment in flexible cavovarus deformity patients when performing the Coleman block test when compared to normal standing position and to controls. METHODS: Twenty patients (40 feet) with flexible cavovarus deformity and 20 volunteer controls (40 feet) with normal foot alignment underwent WBCT imaging of the foot and ankle. Cavovarus patients were assessed in normal orthostatic and Coleman block test positions. Foot and ankle offset (FAO), hindfoot alignment angle (HAA), talocalcaneal angle (TCA), subtalar vertical angle (SVA) and talonavicular coverage angle (TNCA) and a CT-simulated soft tissue envelope image, WBCT clinical hindfoot alignment angle (WBCT-CHAA), were evaluated by 2 readers. Measurements were compared between cavovarus nonstressed and stressed positions and to controls. P values of .05 or less were considered significant. RESULTS: The intra- and interobserver intraclass correlation coefficient were good or excellent for all WBCT measurements. Cavovarus patients demonstrated significant correction of WBCT-CHAA (9.7 ± 0.4 degrees), FAO (2.6 ± 0.4%), and TNCA (8.8 ± 1.8 degrees) when performing the Coleman block test (all P values <.0001). However, WBCT-CHAA and FAO measurements were still residually deformed and significantly different from controls (P values of .001 and <.0001, respectively). TNCA values corrected to values similar to healthy controls (P = .29). No differences were observed in cavovarus patients during Coleman block test for the coronal measures: HAA, TCA, and SVA measurements. CONCLUSION: In this study, we observed improvement in the overall 3D WBCT alignment (FAO), axial plane adduction deformity (TNCA), as well as CT simulated clinical hindfoot alignment (WBCT-CHAA) in flexible cavovarus deformity patients when performing a Coleman block test. However, we did not find improvement in measures of coronal alignment of the hindfoot, indicating continued varus positioning of the hindfoot in these patients.

BACKGROUND: Chikungunya fever (CF) is a viral disease, transmitted by alphavirus through Aedes aegypti, and albopictus mosquitoes, affecting several people, mainly in tropical countries, when its transmitter is not under control, and the main symptom of the chronic phase of CF is joint pain. OBJECTIVES: The primary objective of this study was to observe the prevalence, most affected joints, and intensity of chronic joint pain in individuals affected by CF, and also identify the factors associated with chronic joint pain in these individuals. METHODS: Cross-sectional study that evaluated one hundred and thirty volunteers, of both sexes, aged between 20-65 years, with a clinical and/or laboratory diagnosis of CF. The presence of joint pain was investigated using the Brazilian version of the Nordic Questionnaire of Musculoskeletal Symptoms and the intensity of pain using the Visual Analogue Scale. RESULTS: Of the 130 volunteers evaluated, n = 112 (86%) reported currently experiencing chronic joint pain, persistent, for approximately 38.6 ± 1.73 months, with the greatest predominance in the morning (58%). The joints most affected by pain were: the ankles (65.5%), interphalangeal joints of the hands (59.2%), and knees (59.2%). The joints that presented the greatest intensity of pain were: the ankles (5.13 ± 0.34), interphalangeal joints of the hands (4.63 ± 0.34), and knees (4.33 ± 0.33). Sedentary behavior (p = 0.037), increasing age (p = 0.000), and overweight/obesity (p = 0.002) were factors associated with chronic joint pain. CONCLUSION: A high prevalence of chronic, persistent joint pain was observed, with a greater prevalence in the morning. The joints most affected by chronic pain and with the greatest pain intensity were the ankles, and interphalangeal joints of the hands and knees. Sedentary behavior, increasing age, and overweight/obesity were the factors associated with chronic joint pain in individuals affected by CF in this study. Key Points ⢠Individuals affected by CF had a high prevalence of chronic joint pain, persistent and more prevalent in the mornings ⢠The ankles and interphalangeal joints of the hands and knees were the joints with the highest prevalence of pain ⢠The ankles and interphalangeal joints of the hands and knees were the joints with the greatest pain intensity ⢠Sedentary behavior, increasing age, and overweight/obesity were factors associated with chronic joint pain in individuals affected by CF.

INTRODUCTION: Chronic venous disease (CVD) is a highly prevalent disease that presents a wide spectrum of clinical expressions due to abnormalities in the venous system. Patients often have major functional changes that can limit daily activities. However, the functional factors associated with the severity of the disease remain poorly understood. OBJECTIVE: To identify the functional factors associated with CVD severity. METHODS: Seventy-five patients with CVD (92.0% females, 49.6 ± 13.3 years) were evaluated through clinical examination, lower limb perimetry, ankle range of motion (AROM), and lower limb muscle strength by the Heel Rise test, and Sit-to-stand test. Patients were stratified according to the disease severity as mild (telangiectasia, varicose veins, or edema in the lower limbs) or severe CVD (trophic changes or venous ulcer). RESULTS: Patients with severe CVD (n = 13) were older (p = 0.002), predominantly male (p = 0.007), with reduced AROM in dorsiflexion (p = 0.028) and inversion (p = 0.009), reduced lower limb strength by the Heel Rise test (p = 0.040), and greater circumference of the calf (p = 0.020), ankle (p = 0.003), and plantar arch (p = 0.041) when compared to mild CVD (n = 62). Advanced age, male sex, lower ankle range of motion in dorsiflexion, and greater ankle and plantar arch circumferences were associated with CVD severity. However, the ankle circumference (OR 1.258, 95% CI: 1.008-1.570; p = 0.042), together with advanced age and male sex, was the only functional variable that remained independently associated with CVD severity. CONCLUSION: The increased ankle circumference was a determinant of the CVD severity and may assist in risk stratification and guide treatment goals in this population.

SUMMARY: Through anatomical observations, the anatomical characteristics of the inferior extensor retinaculum of ankle (IER) of the ankle joint were elucidated, and its potential applications in treating lateral ankle instability or other conditions were discussed. A total of 12 adult foot specimens were dissected to expose the inferior extensor retinaculum of ankle, and a standard model was established. The pre-experimental scheme guided the recording of general findings, adjacent structures, lateral attachment in the tarsal sinus region, and influence on movement of inferior tendons. 1, attachment mean width: lateral band of IER 6.6±1.38 mm, oblique superomedial band of IER (32.3±3.97 mm), oblique inferomedial band of IER (30.0±5.30 mm) ; 2, mean length: lateral band of IER (78.1±4.20 mm) , oblique superomedial band of IER (14.2±0.80 mm), oblique inferomedial band of IER (71.8±2.61 mm); 3, maximum mean thickness: lateral band of IER (1.52±0.03 mm), oblique superomedial band of IER (0.89±0.05 mm), oblique inferomedial band of IER (0.73±0.16 mm); 4, the closest distance between IER and the tip of lateral malleolus: 23.9±0.83 mm; 5, mean width of the fiber tunnel:lateral fiber tunnel (11.9±1.16 mm), intermedium fiber tunnel (6.8±1.24 mm), medial fiber tunnel (8.6±0.79 mm); 6, mean distance from tunnel midpoint to lateral malleolar tip: lateral fiber tunnel (38.0±3.74 mm), intermedium fiber tunnel (69.8±4.15 mm), medial fiber tunnel (181.1±6.00 mm); 7, the distance between medial dorsal cutaneous nerve and the tip of lateral malleolus on the level of the IER (79.2±8.3 mm) the distance between intermediate cutaneous nerve of dorsum and the tip of lateral malleolus on the level of the IER (57.9±1.02 mm). The inferior extensor retinaculum of ankle is a crucial restraint unit of the anterior ankle tendon, and a comprehensive understanding of its anatomical characteristics holds significant implications for treating chronic ankle instability and exploring potential clinical applications.

BACKGROUND: Peripheral neuropathy due to chemotherapeutic drugs causes alterations in ankle movement during gait. This study aimed to describe the spatiotemporal parameters and ankle kinematics during gait in schoolchildren with acute lymphoblastic leukemia with clinically suspected peripheral neuropathy. METHODS: In children with acute lymphoblastic leukemia in the maintenance phase, we calculated spatiotemporal and kinematic parameters of the ankle during gait using Kinovea® software. Furthermore, we identified alterations in the parameters obtained considering the values of the normality data from a stereophotogrammetry system as the reference values. Finally, we represented the kinematic parameters of the ankles calculated with Kinovea® compared to the normality values of the stereophotogrammetry. FINDINGS: We evaluated 25 schoolchildren; 13 were male (52.0%) with a median age of 88.0months and a median of 60.0 weeks in the maintenance phase, and 54.8% were classified as standard risk. Spatiotemporal parameters: cadence (steps/min), bilateral step length (m), and average gait speed (m/s) in ALL children were significantly lower than reference values (p < 0.001). Except for right mid-stance and bilateral foot strike, initial swing showed that both ankles maintained plantar flexion values during gait, significantly lower in ALL patients (p < 0.05). INTERPRETATION: We identified spatiotemporal and kinematics alterations in schoolchildren with acute lymphoblastic leukemia during all phases of the gait suggestive of alteration in ankle muscles during movement, probably due to peripheral neuropathy; nevertheless, our results should be taken with caution until the accuracy and reliability of Kinovea® software as a diagnostic test compared to the stereophotogrammetric system in children with ALL and healthy peers is proven.

PURPOSE: the os trigonum is a supernumerary bone that may lead to posterior ankle impingement syndrome. The present study aims to assess the prevalence of this bone. METHODS: A meta-analysis regarding the presence of the os trigonum was performed. For this, the MEDLINE and SciElo databases were searched using "os trigonum" as the keyword. Only original articles, theses, books, dissertations, and monographs were included. Papers with a sample size of < 50 individuals were excluded. The data extracted from the articles were: the total sample size, the prevalence of the trigonum, the method of analysis, the region of the sample, and data regarding sex and side (left or right). Statistical analysis was performed using MedCalc Statistical Software version 14.8.1 (MedCalc Software bvba, Ostend, Belgium). The heterogeneity between the studies was assessed using the I² estimation and the Cochran Q test. For all analyses, a random effect was used and a value of p < 0.05 was considered significant. RESULTS: 249 papers were found, while 18 were included in the meta-analysis. A total of 17,626 ankles were included. The pooled prevalence of the os trigonum was 10.3% (95% CI 7-14.1%) in the present study. There was no significant difference regarding sex or side, while studies conducted in imaging exams showed a higher prevalence in comparison to cadaveric studies. CONCLUSION: Our results suggest that the os trigonum is relatively common. Knowledge of the prevalence of the os trigonum may help surgeons and clinicians diagnose posterior ankle impingement syndrome.

INTRODUCTION: ligamentous injuries of the distal tibiofibular syndesmosis resulting in its opening are common occurrences in traumatology; however, their diagnosis poses a challenge for orthopedic surgeons. The tibioastragaloid mortise radiograph view is the most commonly used method for diagnosing this type of injury, but its reliability is compromised due to variations in ankle positioning during the study, which often depend on the operator. OBJECTIVE: to demonstrate that the designed device achieves a correct and consistent radiographic image of the distal tibiofibular syndesmosis in the mortise view. MATERIAL AND METHODS: we present a prospective, longitudinal, observational study. We designed a polypropylene device that maintains the ankle at 90 degrees of dorsiflexion and 15 degrees of internal rotation. The device was used to take mortise view radiographs of healthy ankles, and corresponding measurements were taken to assess the syndesmosis. RESULTS: we evaluated a total of 46 radiographs of healthy ankles, with a predominance of left ankles. The obtained measurements were as follows: anterior tibiofibular distance (ATFD) ranged from 3 to 6 mm, posterior tibiofibular distance (PTFD) ranged from 1 to 3 mm, tibiofibular clear space (TFCS) ranged from 2 to 3 mm, and a Merle D'Aubigne ratio of 2:1 was observed in all ankles. When comparing the measurements obtained with those established by Harper and Keller, no statistically significant difference was found (2 < 5). CONCLUSION: with the use of the designed device, we achieved a correct and consistent radiographic image of the mortise and the distal tibiofibular syndesmosis.
INTRODUCCIÓN: las lesiones ligamentarias de la sindesmosis tibioperonea distal que ocasionan apertura de la misma son muy frecuentes en traumatología; sin embargo, su diagnóstico es un reto para el cirujano ortopedista. La radiografía de la mortaja tibioastragalina es el método más utilizado para el diagnóstico de este tipo de lesiones, pero es poco confiable ya que la posición del tobillo durante el estudio suele variar dependiendo del operador. OBJETIVO: demostrar que con el uso del dispositivo diseñado se logra una imagen radiográfica correcta y constante de la sindesmosis tibioperonea distal en la proyección de la mortaja. MATERIAL Y MÉTODOS: estudio prospectivo, longitudinal y observacional. Diseñamos un dispositivo de polipropileno que mantiene el tobillo a 90 grados de dorsiflexión y rotación interna de 15 grados. Aplicamos el dispositivo para tomar radiografías de la mortaja en tobillos sanos y les realizamos las mediciones correspondientes para valorar la sindesmosis. RESULTADOS: valoramos un total de 46 radiografías de tobillos sanos, con un predominio de tobillos izquierdos. Las mediciones conseguidas fueron las siguientes: espacio tibioperoneo (ETP) de 3 a 6 mm, la superposición tibioperonea (STP) de 1 a 3 mm, espacio astrágalo-tibial medial (EATM) de 2 a 3 mm y una relación de Merle D'Aubigne de 2:1 en todos los tobillos. Al comparar las mediciones obtenidas con las establecidas por Harper y Keller, no se encontró una diferencia estadísticamente significativa (2 < 5). CONCLUSIÓN: con el uso del dispositivo diseñado, obtuvimos una correcta y constante imagen radiográfica de la mortaja y la sindesmosis tibioperonea distal.

Osteochondral lesions of the talus (OLTs) are the lesions that affect the articular cartilage and the subchondral bone of the talus. Symptoms develop between 6 and 12 months after the index trauma and are associated with degradation of quality of life. Two-thirds of the lesions (73%) are located on the medial part of the talus, 28% of the lesions are posteromedial, and 31% of the lesions are centromedial. Currently, OLT of up to 100 mm2 can behave in a more indolent condition, and above that area, the defect tends to transmit more shearing forces to adjacent cartilage and is more symptomatic.

SUMMARY: Traumatic ankle osteoarthritis is a degenerative condition resulting from traumatic injuries. The objective of this study was to evaluate the impact of minimally invasive ankle joint fusion surgery on ankle function, oxidative damage, and inflammatory factor levels in traumatic ankle osteoarthritis patients. A total of 112 traumatic ankle osteoarthritis patients treated in our hospital from January 2022 to January 2023 were enrolled. They were randomly rolled into a control group (Group C) and an experimental group (Group E), with the former undergoing conventional open ankle joint fusion surgery and the latter receiving minimally invasive ankle joint fusion surgery. A comparison was made between the two groups based on American Orthopedic Foot and Ankle Society (AOFAS), bony fusion rates, and visual analog scale (VAS) scores at pre-operation, and at 1, 2, and 3 months post-operation. Additionally, serum oxidative damage indicators and inflammatory factor levels were measured to evaluate the recovery effects in both groups. Relative to Group C, Group E showed drastically increased AOFAS scores and bony fusion rates (P<0.05), as well as greatly decreased VAS scores (P<0.05). Moreover, Group E exhibited more pronounced improvements in oxidative damage indicators and inflammatory factors versus Group C (P<0.05). Minimally invasive ankle joint fusion surgery drastically improves ankle function in traumatic ankle osteoarthritis patients and reduces levels of oxidative damage and inflammatory response. This provides an important clinical treatment option.
La osteoartritis traumática del tobillo es una afección degenerativa resultante de lesiones traumáticas. El objetivo de este estudio fue evaluar el impacto de la cirugía mínimamente invasiva de fusión de la articulación talocrural sobre la función del tobillo, el daño oxidativo y los niveles de factor inflamatorio en pacientes con osteoartritis traumática del tobillo. Se inscribieron un total de 112 pacientes con artrosis traumática de tobillo tratados en nuestro hospital desde enero de 2022 hasta enero de 2023. Fueron divididos aleatoriamente en un grupo de control (Grupo C) y un grupo experimental (Grupo E), donde el primero se sometió a una cirugía de fusión de la articulación talocrural abierta convencional y el segundo recibió una cirugía de fusión de la articulación talocrural mínimamente invasiva. Se realizó una comparación entre los dos grupos según la Sociedad Estadounidense de Ortopedia de Pie y Tobillo (AOFAS), las tasas de fusión ósea y las puntuaciones de la escala visual analógica (EVA) antes de la operación y 1, 2 y 3 meses después de la operación. Además, se midieron los indicadores de daño oxidativo sérico y los niveles de factor inflamatorio para evaluar los efectos de la recuperación en ambos grupos. En relación con el grupo C, el grupo E mostró puntuaciones AOFAS y tasas de fusión ósea drásticamente aumentadas (P <0,05), así como puntuaciones VAS muy disminuidas (P <0,05). Además, el grupo E exhibió mejoras más pronunciadas en los indicadores de daño oxidativo y factores inflamatorios en comparación con el grupo C (P <0,05). La cirugía de fusión de la articulación talocrural mínimamente invasiva mejora drásticamente la función del tobillo en pacientes con osteoartritis traumática del tobillo y reduce los niveles de daño oxidativo y la respuesta inflamatoria.

This research aimed to determine whether triceps surae delayed onset muscle soreness (DOMS) affects stability while performing different postural control tasks requiring upright and landing stabilization. Twenty-four participants who self-reported as healthy were recruited. Pre and 48 h after a protocol to induce DOMS in the triceps surae, participants were evaluated for DOMS perception, pressure pain threshold, and postural control (assessed by the center of pressure, CoP) during different standing and landing stabilization tasks. We found higher DOMS perception and lower pressure pain threshold 48 h after the exercise. Mediolateral CoP displacement was more sensitive to DOMS across different postural tasks, but no effects were found for bilateral standing. The landing time to stabilization elicited high individual variability in the presence of DOMS. Effects of DOMS in the performance of less challenging tasks, such as bipedal standing, were not found. We conclude that DOMS in the triceps surae impairs mediolateral postural control during challenging tasks such as unilateral standing and body forward lean. It highlights the need for caution and individualized approaches when incorporating movements requiring frontal plane control in training and rehabilitation sessions under the presence of DOMS.

Surgical site infections (SSI) constitute 31% of all hospital-acquired conditions, with ankle and foot surgical procedures showing an incidence of SSI ranging from 0.5% to 6.5%. This study aimed to assess the incidence of both superficial and deep surgical site infections in foot and ankle surgery, along with associated factors. Conducted as a retrospective cohort study, it included 2180 patients undergoing foot and ankle surgery in a private hospital between 2014 and 2020, encompassing elective and trauma cases. Outcome variables comprised SSI, while predictor variables encompassed sex, age, diabetes mellitus, systemic arterial hypertension, smoking, American Society of Anesthesiologists (ASA) score, and body mass index. Logistic regression models were employed to identify associations between study variables. The incidence of surgical site infections stood at 4% (83/2180), comprising a rate of 2.8% (57/2180) for superficial infections and 1.2% (26/2180) for deep infections. Smoking (OR 2.9, 95%CI 1.4-5.3) and ASA score >2 (OR 3.4, 95%CI 1.2-8.4) emerged as independent factors associated with surgical site infections. The group with deep infections exhibited higher proportions of smokers (p = 0.002), systemic arterial hypertension (p = 0.018), trauma surgery (p = 0.049), and an ASA score >2 (p = 0.011). Overall infection incidence in this cohort reached 4%, with trauma cases, smoking, hypertension, and an ASA score >2 independently linked to deep infections. Surgeons should be cognizant of these risk factors when managing prophylactic antibiotic regimens for patients.

BACKGROUND: Some children and adolescents can develop persistent pain and instability following inversion injuries of the ankle. In these cases, imaging exams could reveal small bone fragments distal to the lateral malleolus. For these patients, regular conservative treatment may not be successful, requiring additional management, which can include surgical treatment. This study aimed to present the short-to-midterm functional and clinical outcomes of a series of 12 pediatric and adolescent patients who underwent ligament repair surgery due to chronic instability associated with the presence of osseous components in the lateral ligaments. METHODS: A review of 12 patients treated with surgical ligament reconstruction of the ankle was evaluated. Clinical and functional evaluations were based on comparing the Visual Analogue Scale (VAS), AOFAS ankle-hindfoot score, and residual symptoms before and after the surgical intervention. RESULTS: Before the reconstructive approach, the mean VAS was 2.41 and the mean AOFAS score was 74.16. After the procedure, the standard VAS declined to zero, and the AOFAS score was 100 in all patients. The mean follow-up was 6.33 months. CONCLUSION: The surgical approach in children and adolescents with symptomatic ankle instability due to the presence of osseous fragments after an initial inversion trauma provided adequate clinical and functional results at short-to-midterm follow-up. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Ankle osteoarthritis (AOA) is associated with pain and variable functional limitation, demanding clinical treatment and possible surgical indication when conservative measures are ineffective - arthrodesis has been the procedure of choice, because it reduces pain, restores joint alignment and makes the segment stable, preserving gait. The present study reports 3 cases (3 ankles) of male patients between 49 and 63 years old, with secondary AOA, preoperative American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS AHS) of 27 to 39 points, treated by minimally invasive tibiotalocalcaneal arthrodesis using blocked retrograde intramedullary nail. Hospital stay was of 1 day, and the patients were authorized for immediate loading with removable ambulation orthotics, as tolerated. The physical therapy treatment, introduced since hospitalization, was maintained, prioritizing gait training, strength gain, and proprioception. Clinical and radiographic follow-up was performed at weeks 1, 2, 6, 12 and 24. After evidence of consolidation (between the 6 th and 10 th weeks), the orthotics were removed. One patient complained of pain in the immediate postoperative period and, at the end of the 1 st year, only one patient presented pain during rehabilitation, which was completely resolved with analgesics. Currently, the patients do not present complaints, returning to activities without restrictions - one of them, to the practice of soccer and rappelling. The postoperative AOFAS AHS was from 68 to 86 points.
RESUMEN
PURPOSE: To demonstrate how the use of adjunctive Computed Tomography (CT) can modify diagnosis, treatment options, and operative planning of ankle fractures in comparison with conventional radiographs (CR) in isolation. MATERIALS AND METHODS: A total of 53 patients diagnosed with an ankle fracture between 2011 and 2016, were assessed with CT and CR. Evaluations of the fractures using CR in isolation and CR combined with CT were compared using different readers. Fractures were assessed in terms of type, displacement, size, associated injuries, treatment, patient position and surgical planning. RESULTS: The medial malleolus fractures characteristics (posteromedial fragment and anterior colliculus), the presence of posterior malleolus fracture and its characteristics (displacement, size, posteromedial or posterolateral segment) (ps < 0.042), syndesmosis injury (p < 0.001), and the absence of deltoid ligament lesion (p < 0.001), were more evident with the combination of CT and radiographs. There was an increase in operative indication (p = 0.007), prone positioning (p = 0.002), posterior malleolus surgical treatment (p < 0.001), posterolateral approach for the lateral malleolus (p = 0.003), and syndesmosis fixation (p = 0.020) with the association of CT and CR, among all groups of expertise, with a high interobserver reliability (> 0.75). CONCLUSIONS: The CR may fail to demonstrate subtle lesions, such as posterior malleolus fractures and syndesmotic injuries. The CT evaluation increases the diagnostic precision and improves the quality of information the surgeon receives, what might positively affect patient care. LEVEL OF EVIDENCE III: Retrospective Comparative Study.
