Isolated Tillaux fracture is a rare anterolateral distal tibia fracture frequently misdiagnosed in adults. It typically occurs in adolescents nearing skeletal maturity by avulsion of the anterior-inferior tibiofibular ligament. This case-based literature review study aims to elicit the existing information regarding this fracture in adults, and summarize its injury mechanism, diagnosis, and treatment procedures. According to the literature, this is only the eighth case described: a 46-year-old woman that suffered an isolated Tillaux fracture with 4 mm of displacement, and open reduction and fixation with double cannulated screws were performed. After proper rehabilitation, an excellent functional and radiological outcome was reached. It is important to recognize and appropriately treat these distinct injuries to prevent further instability, degenerative changes, and ankle joint function limitation. Early diagnosis and appropriate osteosynthesis play a significant role in a successful recovery prognosis.

Pediatric ankle injuries are common; ankle epiphyseal fractures are also common in children. But isolated distal epiphyseal fibular fractures of the distal fibula are clinically rare. We describe one unusual case of an adolescent with a completely displaced Salter-Harris type II distal fibular epiphyseal fracture. The attempt of closed reduction failed, and the patient required open reduction and internal fixation. The localized periosteum and the superior peroneal retinaculum were avulsed from the distal fibular metaphysis, with the peroneal tendons underneath exposed but no obvious subluxation. To the best of our knowledge, this combination of injuries has not been previously reported.

BACKGROUND: Despite fractures of Isolated Weber B being prevalent, there is a lack of clarity regarding the relative effectiveness of surgical versus conservative treatment. This systematic review and meta-analysis aimed to investigate the clinical effects and complications of surgical versus conservative treatment of the Isolated Weber B ankle fractures.
METHODS: This study involved thorough searches across multiple electronic databases, including PubMed, Cochrane, Embase, and Web of Science, to identify all relevant publications on Isolated Weber B ankle fractures repaired through surgical versus conservative treatment. Through a comprehensive meta-analysis, several outcomes were evaluated, including post-operative function, complications and reoperation rate.
RESULTS: Six articles involving 818 patients who met the inclusion criteria. Among these participants, 350 were male and 636 were female. 651 patients received conservative treatment, while 396 underwent surgical intervention. The findings indicate no significant differences in OMAS, FAOQ, PCS, MCS scores, and return to work between surgical and non-surgical treatments for isolated Weber B ankle fractures. However, compared with surgical treatment, non-surgical treatment has a higher AOFAS score(MD = -5.31, 95% CI = [-9.06, -1.55], P = 0.20, I2 = 39%), lower VAS score(MD = 0.72, 95% CI = [0.33, 1.10], P = 0.69, I2 = 0%), lower complication rate (RR = 3.06, 95% CI = [1.58, 6.01], P = 0.05, I2 = 54%), and lower reoperation rate(RR = 8.40, 95% CI = [1.57, 45.06], P = 0.05, I2 = 67%).
CONCLUSIONS:

Weber Type B fractures often arise from external rotation with the foot supinated or pronated. Altered tibiofibular joint kinematics in Weber B fractures are responsible for syndesmotic damage seen in Weber B fractures. Weber B fractures are managed using open reduction and internal fixation if displaced. The syndesmosis is injured in up to 40% of cases resulting in an unstable injury with a syndesmotic diastasis. This systematic review aimed to evaluate the current literature on syndesmotic fixation in Weber B fractures, assess the outcomes and complications of syndesmotic fixation and assess the necessity of syndesmotic fixation in Weber B fractures. A search was carried out on the EMBASE, PubMed and CINAHL databases and eight studies assessing the outcomes of syndesmotic fixations versus no syndesmotic fixation with 292 Weber B ankle fractures were included in this systematic review. Results showed significant heterogeneity so a narrative review was conducted. Results of these studies showed that functional, radiological, and quality-of-life outcomes and incidences of post-traumatic osteoarthritis in patients with syndesmotic screws were similar to those of patients not managed with syndesmotic screws. Only one favoured syndesmotic fixation in all cases of diastasis. As such, syndesmotic fixation with screws may not be necessary in the management of Weber B fractures. Screws are also associated with breakage, loosening, local irritation and infections. Suture button devices and antiglide fixation techniques appear to be valid alternatives to syndesmotic screws. It was found that there was no need for routine hardware removal unless the hardware was causing significant side effects for the patient.

OBJECTIVE: There are two main surgical fixation methods for the posterior malleolar fractures (PMFs), the anterior-to-posterior (AP) screws or via the posterolateral (PL) approach utilizing a buttress plate. This review aims to compare the clinical outcome between the AP screw fixation and the PL plate fixation for treating PMFs.
METHODS: We searched all relevant publications about PMFs treated with AP screws or PL plates through electronic databases including the PubMed, the Cochrane Library, the Embase, the Wiley online library and the Web of Science. The meta-analysis was conducted to evaluated clinical outcomes including reduction quality, post-operative function and complications.
RESULTS: Six studies (one single randomized controlled trial and five retrospective cohort studies) were enrolled. 172 patients underwent AP screw fixation and 214 patients underwent PL plate fixation with a total of 386 patients (169 males and 217 females). The PL plating group yielded better AOFAS scores(MD = 6.97, 95 % CI=[4.68, 9.27], P＜0.00001, I2 =0 %) and was more likely to achieve excellent anatomical reduction(OR=5.49, 95 % CI=[1.06, 28.42], P = 0.04, I2 =80 %). No differences were found in the bad reduction quality, incidences of complications (arthritis, neuralgia, superficial wound healing problems and implant failure), the walking VAS scores and the dorsiflexion restriction degrees.
CONCLUSIONS: We suggest that the PL plate fixation method has the clinical benefit of achieving anatomical reduction and better AOFAS scores over the AP screw fixation for treating PMFs. No differences were found in the incidences of complications ( arthritis, neuralgia, superficial wound healing problems and implant failure), the walking VAS scores and the dorsiflexion restriction degrees. The posterior approach and the direct reduction are recommended for the treatment of the PMFs.

UNASSIGNED: Arthroscopic-assisted treatment of ankle fractures has proven useful in the adult population, but little evidence exists for the utilization of arthroscopic-assisted ankle fracture fixation in the pediatric population. The purpose of this systematic review is to examine the management of pediatric ankle fractures using arthroscopy.
UNASSIGNED: A systematic review was performed using PubMed, Web of Science, CINAHL, and MEDLINE from database inception to February 22nd, 2023. Inclusion criteria for this systematic review was pediatric population less than age 18, arthroscopic surgery management, and ankle fracture.
UNASSIGNED: A total of 19 articles (n=30 patients) out of 176 articles met final inclusion criteria with all articles consisting of case reports or case series. The average patient age was 13.8±1.6 years. Sixteen of the patients (53%) had arthroscopic surgery along with an adjunct surgery as indicated, whereas 14 patients (47%) had arthroscopic surgery with or without percutaneous fixation. A high majority of patients demonstrated full range-of-motion and large improvements in function.
UNASSIGNED: Arthroscopy is used with percutaneous fixation or in adjunct to open approaches for pediatric ankle fracture management with good results. More research is needed to determine the utility of arthroscopy in the management of pediatric ankle fractures.

OBJECTIVE: This systematic review aimed to analyse the effect of early weight bearing versus late weight bearing on rehabilitation outcomes after ankle fractures, which primarily include ankle function scores, time to return to work/daily life and complication rates.
METHODS: The China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, China Science and Technology Journal, Web of Science, PubMed, Embase and Cochrane Library databases were searched. The focus was on identifying randomised controlled trials centred on early weight-bearing interventions for post-operative ankle fracture rehabilitation. All databases were searched for eligible studies published within the period from database inception to 20 June 2023. The eligible studies were screened according to the inclusion criteria. Study quality was evaluated using the methodology recommended by the Cochrane Handbook for the Systematic Evaluation of Interventions. Two authors independently performed the literature search and data extraction. Eligible studies were subjected to meta-analyses using Review Manager 5.3. Based on the time points at which post-operative ankle function was reported in the studies included in this paper, we decided to perform a meta-analysis of ankle function scores at 6 weeks post-operatively, 12 weeks post-operatively, 24-26 weeks post-operatively and 1 year post-operatively.
RESULTS: A total of 11 papers, comprising 862 patients, were included. Meta-analysis indicated that patients receiving early weight-bearing interventions, which referred to weight-bearing for 6 weeks post-operatively, experienced enhancements in ankle function scores (Olerud-Molander score, AOFAS score or Baird-Jackson score) at various post-operative milestones: 6 weeks (SMD = 0.69, 95% CI: 0.49-0.88 and p < 0.01), 12 weeks (SMD = 0.57, 95% CI: 0.22-0.92 and p < 0.01) and the 24-26 weeks range (SMD = 0.52, 95% CI: 0.20-0.85 and p < 0.01). The results of subgroup analyses revealed that the effects of early weight-bearing interventions were influenced by ankle range-of-motion exercises. Additionally, early weight bearing allows patients to return to daily life and work earlier, which was evaluated by time when they resumed their preinjury activities (MD = -2.74, 95% CI: -3.46 to -2.02 and p < 0.01), with no distinct elevation in the incidence of complications (RR = 1.49, 95% CI: 0.85-2.61 and p > 0.05).
CONCLUSIONS: The results showed that early weight bearing is effective in improving ankle function among post-operative ankle fracture patients and allows patients to return to daily life earlier. Significantly, the safety profile of early weight bearing remains favourable, with no higher risk of complications than late weight bearing.

BACKGROUND: Many approaches to management of medial malleolar fractures are described in the literature however, their morphology is under investigated. The aim of this study was to analyse the morphology of medial malleolar fractures to identify any association with medial malleolar fracture non-union or malunion.
METHODS: Patients who had undergone surgical fixation of their MMF were identified from 2012 to 2022, using electronic patient records. Retrospective analysis of their preoperative, intraoperative, and postoperative radiographs was performed to determine their morphology and prevalence of non-union and malunion. Lauge-Hansen classification was used to characterise ankle fracture morphology and Herscovici classification to characterise MMF morphology.
RESULTS: A total of 650 patients were identified across a 10-year period which could be included in the study. The overall non-union rate for our cohort was 18.77% (122/650). The overall malunion rate was 6.92% (45/650). Herscovici type A fractures were significantly more frequently mal-reduced at time of surgery as compared to other fracture types (p = .003). Medial wall blowout combined with Hercovici type B fractures showed a significant increase in malunion rate. There is a higher rate of bone union in patients who had been anatomically reduced.
CONCLUSIONS: The morphology of medial malleolar fractures does have an impact of the radiological outcome following surgical management. Medial wall blowout fractures were most prevalent in adduction-type injuries; however, it should not be ruled out in rotational injuries with medial wall blowouts combined with and Herscovici type B fractures showing a significant increase in malunions. Herscovici type A fractures had significantly higher malreductions.
METHODS: Level 3 - Retrospective Cohort Study.

Bosworth fracture (BF) is a rare, but a severe injury to the ankle, characterized by displacement of a fragment of the fractured fibula (mostly of Weber B type) from the tibiofibular incisure to the posterior surface of the distal tibia. In 70% of cases, it is associated with a fracture of the posterior malleolus. This injury is not quite well known, with only 175 cases described in the literature to date. BF requires CT examination, including 3D reconstructions. Closed reduction almost always fails as there is an increased risk of compartment syndrome, mainly after repeated attempts at closed reduction. Therefore, operative treatment is indicated as a standard. The outcome of the operation should be always checked by postoperative CT examination.

Cortical screw fixation across the tibiofibular joint is the mainstay of treatment for syndesmotic injury. Dynamic fixation devices have been developed offering similar advantages to screw fixation in terms of reduction and stability of the syndesmosis. Dynamic fixation may also facilitate a more physiological movement between the tibiofibular joint and thus incur less morbidity. Patient\'s rehabilitation potential is enhanced and reduces the need for hardware removal. Our systematic review aims to analyse the relevant current literature and compare screw fixation to dynamic fixation in the treatment of syndesmotic injury associated with acute ankle fractures. A literature search was performed on Pubmed and Ovid Medline to find scientific papers relating to syndesmotic fixation in acute ankle fractures. Papers were screened and included dependent on predetermined criteria. Risk of bias was assessed after screening full papers by two independent reviewers. Tables and analysis were made using Microsoft excel. A total of 8 papers with 673 patients were included. We found no functional difference between screw fixation or dynamic fixation groups at final follow-up. Three papers showed statistically significant lower rates of reoperation in the dynamic fixation group. Dynamic fixation may offer lower post operative complications and reoperation rates. Therefore, dynamic fixation may be a beneficial alternative treatment compared to traditionally used syndesmotic screws.
