RESUMEN

Introduction: The posterior cruciate ligament (PCL) is a vital structure in knee biomechanics, and its avulsion fractures present a unique challenge. This prospective cohort study was conducted at Grant Government Medical College and JJ Hospital, Mumbai, aimed to assess the clinical outcomes of open reduction and internal fixation (ORIF) utilizing cancellous screws and ethibond suture augmentation for PCL avulsion fractures. PCL avulsion fractures often result from traumatic incidents, such as road traffic accidents, and are associated with complications if left untreated. Materials and Methods: Patients aged 20-45 years with isolated PCL avulsion fractures, confirmed by clinical and radiological assessments, were included. Seven eligible patients underwent ORIF, and outcomes were evaluated through clinical assessments, radiological imaging, and the Lysholm knee scoring system. Follow-ups were conducted for a mean time of 13.2 months, assessing stability, range of motion, and complications. Results: The study demonstrated a mean post-operative Lysholm score of 93.8, significantly improved from the pre-operative score of 49.6. Post-operative knee flexion averaged 125.2°. Fracture healing was observed in all cases, and complications were minimal. The study provides evidence of the effectiveness of ORIF with ethibond suture augmentation for PCL avulsion fractures. Conclusion: The study concludes that the proposed surgical technique yields positive outcomes, including enhanced knee functionality, successful fracture healing, and minimal complications. This approach, combining cancellous screws and ethibond suture augmentation, presents a promising option for the management of PCL avulsion fractures, contributing to the diverse landscape of effective treatment modalities.

RESUMEN

Distal radius fractures are among the most common pediatric injuries, affecting thousands of children each year. These fractures often require clinical intervention to reduce displacement and ensure the proper healing of the growth plate and wrist bone. The primary objective of this comprehensive analysis is to compare the effectiveness of open reduction and internal fixation (ORIF) versus cast placement in the treatment of pediatric distal radius fractures, with the aim of identifying the optimal treatment approach. Therefore, a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted on pediatric distal radius displacement fractures using extensive database searches from 2000 to 2024 for specific keywords, ensuring transparency and reproducibility. Our findings indicate that higher displacement necessitates ORIF to minimize long-term complications and ensure better functional outcomes for pediatric patients. Rare studies comparing ORIF and cast placement are analyzed, emphasizing the advantages and limitations of each approach. The document concludes that the choice between ORIF and casting depends on factors such as fracture severity, patient's age, and specific characteristics of the injury to ensure optimal outcomes in pediatric distal radius fracture management. In conclusion, our data suggests that ORIF and cast placement each have pros and cons for pediatric distal radius fractures, with the best treatment depending on fracture specifics and patient factors, but neither method is clearly superior for long-term outcomes.

RESUMEN

Background Fractures of the humerus are one of the more common fractures in the United States and a cause of fragility fractures in the elderly population. This study aims to understand recent trends in the demographic factors correlated with humeral shaft fractures (HSF) and humeral shaft fracture nonunion (HSFN) following open reduction internal fixation (ORIF) and intramedullary nailing (IMN). Methods The TriNetX database was used to query using International Classification of Diseases-10 (ICD10) diagnosis codes for patients who sustained HSF between 2017 and 2022. Patients were then organized into cohorts based on Current Procedural Terminology (CPT) codes 24515 and 24516 for ORIF and IMN of HSFs, respectively. Subsequent nonunion after operative management was queried. Descriptive and comparative analysis was performed to examine the differences observed between patients based on age, sex, ethnicity, race, and smoking status as well as surgical management across the six-year study period. Results The incidence of HSF increased from 7,108 in 2017 to 8,450 in 2022. The rate of HSF ORIF increased from 12% to 17% while the nonunion rate following ORIF decreased from 4% to 3%. The rate of HSF IMN increased from 4% to 6% and the rate of nonunion following IMN increased from 2% to 4%. The overall rate of HSFN surgery was 1.7% with slight decreasing trend over the past year. Conclusion It is speculated that improved care and surgical indications resulted in a lower rate of nonunion despite an increase in the overall rate of HSF and its operative managements.

RESUMEN

Purpose There have been numerous advancements in the strategies used for treating mandibular fractures in the present times, while open reduction and internal fixation is still accepted as the most preferred treatment option for such fractures despite numerous drawbacks. The aim of the present prospective, randomized controlled study was to evaluate the clinical outcome including neurosensory deficit and pain score variables in mandibular fractures that were treated using rigid internal fixation with three-dimensional (3D) miniplate internal fixation. Materials and Methods For the present study, a total of 20 patients of either sex in an age range of 18 to 55 years with simultaneous angle and contralateral body/parasymphysis fractures of the mandible were included, while the clinical outcome was compared in relation to the two groups wherein different treatment options were used including using rigid internal fixation in one as against 3D miniplate internal fixation in the other. Results Pairwise comparison of pain scores in Group I and Group II patients by the Mann-Whitney U-test at different time zones revealed the results to be statistically significant for all pairs except when the findings were compared between 1 month and 3 months after the procedure in Group II patients. Also, significant recovery was observed in both Group I and II patients during healing when assessed preoperatively to 1 month and then 3 months after the procedure with the results being statistically highly significant in case of the variations observed in relation to the neurosensory deficit observed at different time zones for both Group I and II patients ( p = 0.0001). Conclusion Based on the results obtained, it can be concluded that 3D miniplate-led osteosynthesis was found comparable to the osteosynthesis accomplished using reconstruction plates during fixation of unfavorable body/parasymphysis fractures of mandible in study, providing optimal stability, while satisfactorily meeting the biomechanical requirements for occlusal loading, and an early return to normal function.

RESUMEN

This case report outlines the effective use of the Titanium Elastic Nail System (TENS) for treating a peri-implant mid-shaft radius and ulna fracture in a patient with previous elbow arthrodesis and rotational full-thickness flap coverage. Given the paucity of literature surrounding this complex problem, we present a minimally - invasive treatment option which facilitated complete fracture healing, demonstrating the TENS's efficacy in complex orthopedic scenarios.

RESUMEN

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The study aimed to compare the radiological parameters, clinical outcomes, and long-term effects of the posterior osteosynthesis with polyaxial screw-rod system and the monoaxial screw-rod system in the treatment of unstable atlas fractures. METHODS: We retrospectively analyzed the clinical data of 33 patients with posterior ORIF for unstable atlas fractures in our hospital from August 2013 to June 2020, with a minimum of 3 years of follow-up. Polyaxial screws (group A) were used in 12 patients and monoaxial screws (group B) in 21 patients. Perioperative data, radiological parameters, and clinical outcomes were collected and compared between the 2 surgical approaches. RESULTS: The operative time, blood loss, time of screw-rod system placement, and hospital stay were significantly lower in group A than in group B. At the last follow-up, the visual analog scale (VAS) score and anterior arch reduction rate of the atlas in group A were lower than those in group B, while the lateral mass displacement (LMD) in group A was higher than that in group B. There was no significant difference between Group A and Group B in terms of the anterior atlantodental interval (AADI), posterior arch reduction rate of the atlas, range of motion (ROM), and neck disability index (NDI). CONCLUSIONS: Monoaxial screws can achieve better reduction results for unstable atlas fractures, especially for the anterior arch of atlas. However, the surgical operation of monoaxial screws is more complicated than that of polyaxial screws and has more complications. Appropriate implants should be selected for the treatment of unstable atlas fractures based on the type of atlas fracture, the experience of surgeons, and the demands of patients.

RESUMEN

Background: Lateral physeal condylar humerus fractures in pediatric patients aged 1-13 rank as the second most common elbow injury, occurring with a frequency ranging from 5% to 16.8%. There exists an ongoing debate regarding the surgical management of these fractures. This study aims to evaluate the efficacy of Open Reduction and Internal Fixation (ORIF) and Closed Reduction and Percutaneous Pinning (CRPP) as suitable surgical treatments for displaced unstable fractures of the lateral condyle physeal humerus in children. The comparison encompasses the results of ORIF and CRPP, alongside clinical and radiographic outcomes and complication rates. Method: A retrospective review was conducted at the Department of Orthopedic Surgery in the research hospital. A cohort of 27 patients treated between 2016 and 2023 were analyzed, 19 patients meeting inclusion criteria. The fracture pattern and degree of displacement were assessed, with specialized radiologists, doctors, and surgeons in agreement. Among the patients, 11 underwent CRPP 7 type 3and 4 type 2, while 16 received ORIF 12 type 4 and 4 type 5. Data collection included fracture type, surgical method, operation time, pre and post-operative displacement, casting period, bone union condition, follow-up records, range of motion, complications, delayed union, lateral spurring, and pin removal records. Results: For CRPP, the mean time for pin removal was 5.42 weeks, with excellent bone union and an average operation time of 34.57 min. Criteria of Hardacre showed 28.57% of cases as good and 71.42% as excellent. Similarly, ORIF demonstrated a mean operation time of 42.5 min, with the fracture healing within 5.33 weeks and the pin being removed after 15 days on average. Criteria of Hardacre indicated 25% of cases as good and 75% as excellent. Both groups showed satisfactory outcomes, with no complications such as osteomyelitis, nonunion, malunion, delayed union, myositis ossificans, physeal growth arrest, tardy ulnar nerve palsy, cubitus valgus, or varus, and no cases requiring re-surgery. Conclusion: Both CRPP and ORIF are effective surgical methods for treating lateral physeal condylar humeral fractures (types 3 and 4 according to the Song classification) in children, demonstrating satisfactory outcomes. Notably, regardless of displacement (2 mm and >2 mm), both methods yield similar results, albeit with CRPP offering the advantage of avoiding incisions. Overall, both procedures are safe, with favorable bone healing outcomes.

RESUMEN

BACKGROUND: Osteosynthesis of unstable atlas fractures preserves joint motion and therefore has a distinct advantage over a range of treatment procedures. To prevent the potential disadvantages associated with osteosynthesis, a new atlas lateral mass screw-plate (LMSP) system has been designed. However, the biomechanical role of using the LMSP system in atlas internal fixation is not known. The aim of this study was to compare the biomechanical stability of a new LMSP with traditional posterior screw and rod (PSR) fixation techniques on the occipitocervical junction (C0-C2) through finite element analysis. METHODS: A nonlinear C0-C2 finite element model of the intact upper cervical spine was developed and validated. The unstable model using the PSR system was then compared with the model using the LMSP system for fixation. A vertical load of 40 N was applied to the C0 to simulate head weight, while a torque of 1.5 Nm was applied to the C0 to simulate flexion, extension, lateral bending, and axial rotation. RESULTS: The range of motion of both systems was close to the intact model. Compared with the LMSP system model, the PSR system model increased flexion, extension, lateral bending, and axial rotation by 4.9%, 3.0%, 5.0%, and 29.5% in the C0-C1 segments, and 4.9%, 2.7%, 2.4%, and 22.6% in the C1-C2, respectively. In flexion, extension, and lateral bending motion, the LMSP system model exhibited similar stress to the PSR system model, while in axial rotation, the PSR system model exhibited higher stress. CONCLUSIONS: The findings of our study indicate that the two tested system models provide comparable stability. However, better stability was achieved during axial rotation with the LMSP system, and in this system, the maximum von Mises stress was less than that of the PSR one. As the atlantoaxial joint functions primarily as a rotational joint, the use of the LMSP system may provide a more stable environment for the joint that has become unstable due to fracture.

RESUMEN

Our study aims to estimate the prevalence of Frey syndrome following open reduction and internal fixation (ORIF) for mandibular fractures. Two reviewers independently conducted a systematic literature search in the Medline and Scopus databases. The pooled prevalence with 95% confidence intervals (CI) was estimated, and quality assessment, outlier analysis, and influential analysis were performed. In total, fifteen eligible studies were included in this meta-analysis. One study was identified as critically influential. The overall prevalence of Frey syndrome following extraoral surgical treatment for mandibular fractures was estimated as 0.01% (95%CI 0%-0.7%) with moderate heterogeneity observed between studies. In the meta-regression analysis with continuous variables, no statistically significant association was observed. Despite the relatively low prevalence, the impact of Frey syndrome on affected individuals should not be underestimated. Additional research will provide a more comprehensive understanding of the underlying factors contributing to Frey syndrome, leading to improved preventive measures and treatment strategies. A better grasp of the prevalence and associated risk factors will aid in the development of guidelines to minimize the occurrence of this syndrome.

RESUMEN

We report on the case of a 52-year-old male who sustained a transverse patellar fracture after tripping on uneven pavement. These fractures can be easy to miss on anteroposterior views, highlighting the importance of multiple radiographic views of the knee. Examination of the knee is also important, as initial clinical appearance can be benign. These fractures are most often seen in adolescents, which makes the current case somewhat unusual.

RESUMEN

A Hoffa fracture is a rare type of femoral fracture that is difficult to treat. Nonoperative treatments usually result in failure; hence, in most cases, surgical treatments are essential. Nonunion following Hoffa fracture appears to be relatively uncommon, and there are limited reports in the literature about this type of nonunion. These reports suggest that open reduction and rigid internal fixation is the standard treatment for this type of nonunion. This study reports the case of a 61-year-old male patient who suffered from left lateral Hoffa fracture after falling from a truck bed. At the former hospital, open reduction and internal fixation were performed with plates and screws at 8 days post-injury. Postoperatively, displacement of the lateral proximal fragment was observed, and the patient reported left knee pain. Therefore, a revision open reduction and internal fixation was performed 4 months post-surgery. However, 6 months after the revision surgery, the patient reported instability and pain in the left knee, and subsequent radiography revealed nonunion of the fracture in the lateral condyle. The patient was referred to our hospital for further treatment. Treatment by re-revision open reduction and internal fixation was deemed challenging, and so rotating hinge knee (RHK) arthroplasty was performed as a salvage treatment. At 3 years post-surgery, no significant problems were observed, and the patient could walk without any assistance. The range of motion of the left knee was 0 to 100° without extension lag, and there was no lateral instability. Standard treatment for Hoffa fracture nonunion is commonly anatomical reduction and rigid internal fixation. However, total knee arthroplasty may be a better option for the treatment of Hoffa fracture nonunion in older patients.

RESUMEN

BACKGROUND: In the treatment of unstable atlas fractures using the combined anterior-posterior approach or the posterior monoaxial screw-rod system, factors such as severe trauma or complex surgical procedures still need to be improved despite the favourable reduction effect. This research described and evaluated a new technique for the treatment of unstable atlas fracture using a self-designed lateral mass screw-plate system. METHODS: A total of 10 patients with unstable atlas fractures using this new screw-plate system from January 2019 to December 2021 were retrospectively reviewed. All patients underwent posterior open reduction and internal fixation (ORIF) with a self-designed screw-plate system. The medical records and radiographs before and after surgery were noted. Preoperative and postoperative CT scans were used to determine the type of fracture and evaluate the reduction of fracture. RESULTS: All 10 patients were successfully operated with this new system, with an average follow-up of 16.7 ± 9.6 months. A total of 10 plates were placed, and all 20 screws were inserted into the atlas lateral masses. The mean operating time was 108.7 ± 20.1 min and the average estimated blood loss was 98.0 ± 41.3 ml. The lateral mass displacement (LMD) averaged 7.1 ± 1.9 mm before surgery and almost achieved satisfactory reduction after surgery. All the fractures achieved bony healing without reduction loss or implant failure. No complications (vertebral artery injury, neurologic deficit, or wound infection) occurred in these 10 patients. At the final follow-up, the anterior atlantodens interval (AADI) was 2.3 ± 0.8 mm and the visual analog scale (VAS) was 0.6 ± 0.7 on average. All patients preserved almost full range of motion of the upper cervical spine and achieved a good clinical outcome at the last follow-up. CONCLUSIONS: Posterior osteosynthesis with this new screw-plate system can provide a new therapeutic strategy for unstable atlas fractures with simple and almost satisfactory reduction.

RESUMEN

AIMS: The aim of this study was to compare open reduction and internal fixation (ORIF) with revision surgery for the surgical management of Unified Classification System (UCS) type B periprosthetic femoral fractures around cemented polished taper-slip femoral components following primary total hip arthroplasty (THA). METHODS: Data were collected for patients admitted to five UK centres. The primary outcome measure was the two-year reoperation rate. Secondary outcomes were time to surgery, transfusion requirements, critical care requirements, length of stay, two-year local complication rates, six-month systemic complication rates, and mortality rates. Comparisons were made by the form of treatment (ORIF vs revision) and UCS type (B1 vs B2/B3). Kaplan-Meier survival analysis was performed with two-year reoperation for any reason as the endpoint. RESULTS: A total of 317 periprosthetic fractures (in 317 patients) with a median follow-up of 3.6 years (interquartile range (IQR) 2.0 to 5.4) were included. The fractures were type B1 in 133 (42.0%), B2 in 170 (53.6%), and B3 in 14 patients (4.4%). ORIF was performed in 167 (52.7%) and revision in 150 patients (47.3%). The two-year reoperation rate (15.3% vs 7.2%; p = 0.021), time to surgery (4.0 days (IQR 2.0 to 7.0) vs 2.0 days (IQR 1.0 to 4.0); p < 0.001), transfusion requirements (55 patients (36.7%) vs 42 patients (25.1%); p = 0.026), critical care requirements (36 patients (24.0%) vs seven patients (4.2%); p < 0.001) and two-year local complication rates (26.7% vs 9.0%; p < 0.001) were significantly higher in the revision group. The two-year rate of survival was significantly higher for ORIF (91.9% (standard error (SE) 0.023%) vs 83.9% (SE 0.031%); p = 0.032) compared with revision. For B1 fractures, the two-year reoperation rate was significantly higher for revision compared with ORIF (29.4% vs 6.0%; p = 0.002) but this was similar for B2 and B3 fractures (9.8% vs 13.5%; p = 0.341). The most common indication for reoperation after revision was dislocation (12 patients; 8.0%). CONCLUSION: Revision surgery has higher reoperation rates, longer surgical waiting times, higher transfusion requirements, and higher critical care requirements than ORIF in the management of periprosthetic fractures around polished taper-slip femoral components after THA. ORIF is a safe option providing anatomical reconstruction is achievable.Cite this article: Bone Joint J 2023;105-B(2):124-134.

RESUMEN

Bilateral sleeve fracture of the patella (SFP) in skeletally immature children is a rare injury. We report the case of a healthy 11-year-old male who suffered bilateral SFP while playing tag. The avulsed fragments of his left patella were highly comminuted. Open reduction and internal fixation (ORIF) were performed using suture anchors, and the knees were immobilized using a cylinder cast for three weeks. At the one-year follow-up assessment, both knees were found to have regained full strength with no extension lag. However, we observed malunion due to lateral shift of the avulsed fragment, cystic lesions, and clicking in the patella, and the patient experienced residual pain in the left knee. Based on this, we conclude that the sleeve fracture of the patella with comminuted cartilaginous fragments was difficult to treat and might have led to poor clinical results if anatomical reduction and fixation had not been performed.

RESUMEN

AIMS: The aim of this study was to investigate the rate of revision for distal femoral arthroplasty (DFA) performed as a primary procedure for native knee fractures using data from the Australian Orthopaedic Association National Joint Arthroplasty Registry (AOANJRR). METHODS: Data from the AOANJRR were obtained for DFA performed as primary procedures for native knee fractures from 1 September 1999 to 31 December 2020. Pathological fractures and revision for failed internal fixation were excluded. The five prostheses identified were the Global Modular Arthroplasty System, the Modular Arthroplasty System, the Modular Universal Tumour And Revision System, the Orthopaedic Salvage System, and the Segmental System. Patient demographic data (age, sex, and American Society of Anesthesiologists grade) were obtained, where available. Kaplan-Meier estimates of survival were used to determine the rate of revision, and the reasons for revision and mortality data were examined. RESULTS: The AOANJRR identified 153 primary DFAs performed for native knee fractures in 151 patients during the study period, with 63.3% of these (n = 97) performed within the last five years. The median follow-up was 2.1 years (interquartile range 0.8 to 4.4). The patient population was 84.8% female (n = 128), with a mean age of 76.1 years (SD 11.9). The cumulative percent revision rate at three years was 10%. The most common reason for revision was loosening, followed by infection. Patient survival at one year was 87.5%, decreasing to 72.8% at three years postoperatively. CONCLUSION: The use of DFA to treat native knee fractures is increasing, with 63.3% of cases performed within the last five years. While long-term data are not available, the results of this study suggest that DFA may be a reasonable option for elderly patients with native knee fractures where fixation is not feasible, or for whom prolonged non-weightbearing may be detrimental.

RESUMEN

BACKGROUND: Optimal management of a displaced midshaft clavicle fracture remains controversial. This study assessed demographic factors, fracture pattern, and surgical technique as potential predictors of surgical complications. Smoking, diabetes, obesity, polytrauma, high-energy mechanism, inpatient status, transverse or comminuted fractures, and single-plating technique were hypothesized to be associated with an increased risk of complications following clavicle fracture open reduction internal fixation (ORIF). METHODS: Consecutive patients with minimum 12-week follow-up from the trauma and sports medicine divisions at a single tertiary institution who presented with a midshaft clavicle fracture and underwent ORIF between 2007 and 2020 were retrospectively identified. Patient demographics, fracture pattern, plating technique, and postoperative complications were recorded. Postoperative complications were classified into major (reoperation) and minor (no reoperation) complications. Chi-squared statistics, Fisher's exact test, analysis of variance, Kruskal-Wallis test, and multivariate logistic regression modeling were utilized with a significance level set to P < .05. RESULTS: One hundred ninety-eight patients (average = 39.5 ± 14.6 years) were identified with an average follow-up of 9.1 ± 10.7 months. The cohort consisted of 155 males (78.3%), 62 smokers (31.3%), and 12 diabetics (6.1%). Injury characteristics revealed 80 transverse fractures (40.4%), 87 oblique fractures (43.9%), and 31 Z-type fractures (15.7%). Seventy-nine patients (39.9%) underwent superior plating, 72 (36.4%) underwent anterior plating, and 47 (23.7%) underwent dual plating. Overall, postoperative complications occurred in 47 patients (23.7%), 29 minor (14.6%) and 18 major (9.1%). Major complications requiring reoperation were symptomatic hardware, nonunion, deep infection, wound dehiscence, and broken hardware. Minor complications consisted of sensory deficit or paresthesia beyond peri-incisional numbness, superficial infections, postoperative pain and/or stiffness, and delayed union. Smoking status (P = .008), obesity (P = .009), and transverse or Z-type fractures (P = .002) were significant prognostic factors for overall complication risk. Only manual labor was predictive of minor complications (P = .019). Transverse or Z-type fractures and single plating were predictive of major complications (P = .004 and P = .008, respectively). No reoperations occurred in patients who underwent dual plating. Smokers (P = .027) with transverse/Z-type fractures (P = .022) were at the highest risk of reoperation with single plating. CONCLUSION: The overall rate of complications following ORIF of displaced midshaft clavicle fracture was 27.3%, with 9.1% requiring reoperation. Given relatively high complication rates, in instances when nonoperative vs. operative management is equivocal, nonoperative management should be strongly considered in obese patients, smokers, and patients who present with transverse or Z-type fracture. If operative management is indicated, use of dual plating may decrease reoperation rates.

RESUMEN

AIMS: The aim of this study was to investigate the outcome of periprosthetic fractures of the humerus and to assess the uniformity of the classifications used for these fractures (including those around elbow and/or shoulder arthroplasties) by performing a systematic review of the literature. METHODS: A systematic search was conducted using the National Institute for Health and Care Excellence Healthcare Databases Advance Search. For inclusion, studies had to report clinical outcomes following the management of periprosthetic fractures of the humerus. The protocol was registered on the PROSPERO database. RESULTS: Overall, 40 studies were included, involving a total of 210 patients. The fractures were reported using very heterogeneous classification systems, as were the functional outcome scores. A total of 60 patients had nonoperative treatment with a 50% rate of nonunion. Fixation was undertaken in 99 patients; successful union was obtained in 93 (93%). Revision of either the humeral stem or the whole arthroplasty was reported in 79 patients with a high rate of union (n = 66; 84%), and a mean rate of complications of 29% (0% to 41%). CONCLUSION: This study highlighted a lack of uniformity in classifying these fractures and reporting the outcome of their treatment. The results may help to inform decision-making with patients, particularly about the rate of complications of nonoperative treatment. There is a need to improve the reporting of the pattern of these fractures using a uniform classification system, and the harmonization of the collection of data relating to the outcome of treatment. Based on this review, we propose a minimum dataset to be used in future studies. Cite this article: Bone Joint J 2022;104-B(4):416-423.

RESUMEN

AIMS: After failed acetabular fractures, total hip arthroplasty (THA) is a challenging procedure and considered the gold standard treatment. The complexity of the procedure depends on the fracture pattern and the initial fracture management. This study's primary aim was to evaluate patient-reported outcome measures (PROMs) for patients who underwent delayed uncemented acetabular THA after acetabular fractures. The secondary aims were to assess the radiological outcome and the incidence of the associated complications in those patients. METHODS: A total of 40 patients underwent cementless acetabular THA following failed treatment of acetabular fractures. The postoperative clinical and radiological outcomes were evaluated for all the cohort. RESULTS: The median (interquartile range (IQR)) Oxford Hip Score (OHS) improved significantly from 9.5 (7 to 11.5), (95% confidence interval (CI) (8 to 10.6)) to 40 (39 to 44), (95% CI (40 to 43)) postoperatively at the latest follow-up (p < 0.001). It was worth noting that the initial acetabular fracture type (simple vs complex), previous acetabular treatment (ORIF vs conservative), fracture union, and restoration of anatomical centre of rotation (COR) did not affect the final OHS. The reconstructed centre of rotation (COR) was restored in 29 (72.5%) patients. The mean abduction angle in whom acetabular fractures were managed conservatively was statistically significantly higher than the surgically treated patients 42.6° (SD 7.4) vs 38° (SD 5.6)) (p = 0.032). We did not have any case of acetabular or femoral loosening at the time of the last follow-up. We had two patients with successful two-stage revision for infection with overall eight-year survival rate was 95.2% (95% CI 86.6% to 100%) with revision for any reason at a median (IQR) duration of follow-up 50 months (16 to 87) months following THA. CONCLUSION: Delayed cementless acetabular THA in patients with previous failed acetabular fracture treatments produces good clinical outcomes (PROMS) with excellent survivorship, despite the technically demanding nature of the procedure. The initial fracture treatment does not influence the outcome of delayed THA. In selected cases of acetabular fractures (either nondisplaced or with secondary congruency), the initial nonoperative treatment neither resulted in large acetabular defects nor required additional acetabular reconstruction at the time of THA.

RESUMEN

AIMS: This systematic review and meta-analysis was conducted to compare open reduction and internal fixation (ORIF) with primary arthrodesis (PA) in the treatment of Lisfranc injuries, regarding patient-reported outcome measures (PROMs), and risk of secondary surgery. The aim was to conclusively determine the best available treatment based on the most complete and recent evidence available. METHODS: A systematic search was conducted in PubMed, Cochrane Controlled Register of Trials (CENTRAL), EMBASE, CINAHL, PEDro, and SPORTDiscus. Additionally, ongoing trial registers and reference lists of included articles were screened. Risk of bias (RoB) and level of evidence were assessed using the Cochrane risk of bias tools and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool. The random and fixed-effect models were used for the statistical analysis. RESULTS: A total of 20 studies were selected for this review, of which 12 were comparative studies fit for meta-analysis, including three randomized controlled trials (RCTs). This resulted in a total analyzed population of 392 patients treated with ORIF and 249 patients treated with PA. The mean differences between the two groups in American Orthopedic Foot and Ankle Society (AOFAS), VAS, and SF-36 scores were -7.41 (95% confidence interval (CI) -13.31 to -1.51), 0.77 (95% CI -0.85 to 2.39), and -1.20 (95% CI -3.86 to 1.46), respectively. CONCLUSION: This is the first study to find a statistically significant difference in PROMs, as measured by the AOFAS score, in favour of PA for the treatment of Lisfranc injuries. However, this difference may not be clinically relevant, and therefore drawing a definitive conclusion requires confirmation by a large prospective high-quality RCT. Such a study should also assess cost-effectiveness, as cost considerations might be decisive in decision-making. Level of Evidence: I Cite this article: Bone Jt Open 2021;2(10):842-849.

RESUMEN

Background  Fractures of the mandibular condyle are common and account for 25% to 50% of all fractures of the mandible. Various methods exist for open reduction and internal fixation (ORIF) of condylar fractures. This study was done to explore three-dimensional (3D) plates as a viable option. Aim  This study aims to evaluate the effectiveness of 3D trapezoidal plates in open reduction and internal fixation of subcondylar fractures. Materials and methodology This was a non-randomized clinical trial conducted on 20 patients who reported at the Department of Oral and Maxillofacial Surgery, Tamil Nadu Government Dental College and Hospital, Chennai, India. The ORIF was done under general anesthesia. A retromandibular transmasseteric approach was used to expose the fracture site, and the fracture was stabilized using 3D titanium trapezoidal plates. Parameters, such as mouth opening, mandibular deviation, occlusion, surgical accessibility, fracture reduction, adaptability, the difference in ramal height, angulation of the fractured condyle, operative time, facial nerve weakness, implant failure, complications, and scar formation were assessed. Statistical analysis was done using Statistical Package for Social Sciences (SPSS), version 21 (IBM SPSS Statistics for Windows, Armonk, NY). Results  There was an improvement in mouth opening and occlusion in the immediate postoperative period. The surgical accessibility ranged from good to excellent. The fracture reduction was excellent in 60% of patients and good in 40%. In one patient, there was a transient weakness of the marginal mandibular nerve which recovered by three months. Another patient had a wound infection that subsided within the first postoperative week. None of the patients had a device failure during the six-month follow-up period. Conclusion  The trapezoidal 3D plates could be considered as a viable option for treating subcondylar fractures of the mandible in terms of surgical accessibility, stability, ease of device placement, stability of reduced fracture, reduced osteosynthesis material requirement, and minimal damage to the surrounding tissues.
