Batar S, Şişman A. Comparison of anteroposterior and posteroanterior screw fixation techniques for posterior malleolar fractures: a retrospective and clinical study. ULUS TRAVMA ACIL CER 2023; 29:1376-1381. [PMID: 38073458 PMCID: PMC10767291 DOI: 10.14744/tjtes.2023.66204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 10/23/2023] [Accepted: 11/23/2023] [Indexed: 12/18/2023]
Abstract
BACKGROUND The posterior malleolus is an important component of the distal tibiofibular complex and plays a crucial role in maintaining ankle joint stability. This study aimed to compare the clinical and radiological outcomes of fixation with anteroposterior (AP) and posteroanterior (PA) compression screws in patients with Haraguchi Type 1 PMFs. METHODS Data from 306 patients who underwent surgery for trimalleolar fractures between January 2018 and March 2022 were retrospectively reviewed, and 60 patients meeting the criteria were included in the study. Thirty-one patients with AP screw fixation and 29 patients with PA screw fixation were compared clinically and radiologically. Radiological parameters such as fracture healing time, step-off amount, displacement amount, and development of arthritis were evaluated. Clinical outcomes including ankle joint range of motion at final follow-up, American Orthopedic Foot and Ankle Society (AOFAS) score, Visual Analog Scale (VAS), and Olerud-Molander Score were compared. RESULTS There were no statistically significant differences between the groups in terms of average age, gender distribution, smoking history, fracture etiology, time from injury to surgery, operation time, fracture healing time, and follow-up duration. Step-off and displacement amounts were lower in the PA screw group (P<0.001, P=0.004, respectively). When comparing the development of arthritis, according to the Kellgren-Lawrence Classification, no signs of arthritis were observed in 62.1% of the PA screw group, while this rate was 22.6% in the AP screw group. Ankle dorsiflexion, plantar flexion range of motion, AOFAS score, Olerud-Molander Score, and VAS results were statistically better in the PA screw group (P=0.002, P=0.001, P=0.002, P=0.001, P=0.002, respectively). There were no significant differences between the groups regarding complications. CONCLUSION Two different screw fixation techniques used in the treatment of trimalleolar fracture patients with Haraguchi Type 1 PMF were compared. In conclusion; percutaneous PA screw fixation is more advantageous than the AP screw fixation method because it provides less step-off in the fracture line, less arthrosis in the ankle, and better functional scores.

Foot Ankle Surg 2023; 29:588-592. [PMID: 37468359 DOI: 10.1016/j.fas.2023.07.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 06/25/2023] [Accepted: 07/02/2023] [Indexed: 07/21/2023]
Abstract
INTRODUCTION Tibiotalocalcaneal (TTC) nailing without joint preparation has been indicated as an alternative to open reduction and internal fixation (ORIF) in the treatment of unstable fragility ankle fractures. We hypothesized that primary hindfoot nailing without joint preparation, and immediate weight bearing can provide a safe and effective treatment for unstable fragility fractures of the ankle compared to ORIF. METHODS A retrospectively single-center cohort was reviewed for all surgically treated ankle fractures in patients aged 75 years and older between 2016 and 2021. The cases were grouped by the surgical technique: ORIF or TTC nailing. Diagnosis and treatment were validated by a review of the radiographs and the patients' charts. Primary outcomes included complication rates and revision rates. The PROMs questionnaires included the Foot and Ankle-Ability Measure (FAAM-ADL) and the Olerud-Molander Ankle Score (OMAS). RESULTS Forty-six cases met the inclusion criteria during the study period. Eighteen in the TTC group and 28 in the ORIF group. The average follow-up was 46.4 months (Median 49.5, SD ± 25.3). The mean age of the TTC group was significantly higher (88.6 versus 81.8, p < 0.001). The mean surgery duration and length of stay were similar. The complication rates were 50.0 % in the ORIF group (28.6 % major) versus 22.2 % in the TTC group (5.6 % major), (p = 0.060). The revision rates were 28.6 % and 11.1 % in the ORIF and TTC groups respectively (p = 0.161). The FAAM-ADL was higher in the ORIF group (62.6 % versus 32.4 %, p = 0.020), as well as the OMAS (60.0 versus 32.8, p = 0.029). CONCLUSION TTC nailing without joint preparation for unstable fragility fractures of the ankle in the extremely elderly provided a better complication profile compared to traditional ORIF. However, PROMs were inferior.

Abstract
PURPOSE Tibial shaft spiral fractures and fractures of the distal third of the tibia (AO:42A/B/C and 43A) frequently occur with non-displaced posterior malleolus fractures (PM). This study investigated the hypothesis that plain X-ray is not sufficient for a reliable diagnosis of associated non-displaced PM fractures in tibial shaft spiral fractures. METHODS 50 X-rays showing 42A/B/C and 43A fractures were evaluated by two groups of physicians, each group was comprised of a resident and a fellowship-trained traumatologist or radiologist. Each group was tasked to make a diagnosis and/or suggest if further imaging was needed. One group was primed with the incidence of PM fractures and asked to explicitly assess the PM. RESULTS Overall, 9.13/25 (SD ± 5.77) PM fractures were diagnosed on X-ray. If the posterior malleolus fracture was named or a CT was requested, the fracture was considered "detected". With this in mind, 14.8 ± 5.95 posterior malleolus fractures were detected. Significantly more fractures were diagnosed/detected (14 vs. 4.25/25; p < 0.001/14.8 vs. 10.5/25; p < 0.001) in the group with awareness. However, there were significantly more false positives in the awareness group (2.5 vs. 0.5; p = 0.024). Senior physicians recognized slightly more fractures than residents (residents: 13.0 ± 7.79; senior physicians: 16.5 ± 3.70; p = 0.040). No significant differences were demonstrated between radiologists and trauma surgeons. The inner-rater reliability was high with 91.2% agreement. Inter-rater reliability showed fair agreement (Fleiss-Kappa 0.274, p < 0.001) across all examiners and moderate agreement (Fleiss-Kappa 0.561, p < 0.001) in group 2. CONCLUSION Only 17% of PM fractures were identified on plain X-ray and awareness of PM only improved diagnosis by 39%. While experiencing improved accuracy, CT imaging should be included in a comprehensive examination of tibial shaft spiral fractures. LEVEL OF EVIDENCE II. Diagnostic prospective cohort study.

Abstract
INTRODUCTION Surgical treatment of AO/OTA 43-C pilon fractures has not yet taken a standard form. We aimed to evaluate whether patients that appeared to be labelled as unsupported columns according to the four-column theory would affect long-term clinical and radiological outcomes. MATERIALS AND METHODS Patients with AO/OTA 43-C type who were treated surgically between January 2010 and December 2019 were included in the study. 53 fractures in 52 patients who received osteosynthesis were categorized based on the fixed columns. These groups were formed as fully supported columns (FSC- Group A), partly supported columns (PSC-Group B), Ankle range of motions (ROM), Burwell Charnley's reduction evaluation criteria, Kellgren-Lawrence ankle osteoarthritis staging system, and American Orthopedic Foot and Ankle Society (AOFAS) Scoring System, Olerud-Molander Ankle Score, Visual Analog Scale were used for evaluating radiological and functional outcomes. RESULTS The mean follow-up period was 72.6 (12-131) months. Mean age was 42.6 (18-76). Two groups were homogenously distributed in terms of age (p = 0.785), sex (p = 0.376), laterality (p = 0.732), smoking status (p = 0.488) and reduction quality. There was no difference in AOFAS score (p = 0.452), Olerud-Molander score (p = 0.354) and VAS scores (p = 0.589). TAS, TLS and TT angle measurements suggested no difference between groups (p = 0.493, p = 0.834, p = 0.577). There was no difference between groups in terms of infection (p = 0.734), malunion (p = 0.688) and arthritis (p = 0.483) CONCLUSION: We presented findings that contradicted the hypothesis positing the existence of four distinct columns in pilon fractures, as well as the notion that each fractured column requires support from distinct implants.

Abstract
OBJECTIVE The aim of this study was to investigate the clinical efficacy of small plate assisted anatomical plate and traditional double plate in the treatment of Rüedi and Allgöwer II - III pilon fracture. METHODS AND MATERIALS The data of 68 patients with pilon fracture admitted to Hospital from June 2017 to June 2020 were retrospectively analyzed. Study group and control group were divided according to different operation methods, with 34 cases in each group. There were 28 cases of Rüedi and Allgöwer II type and 40 cases of Rüedi and Allgöwer III type. Perioperative period data, Ankle joint function score, visual analog scale (VAS) scores and the incidence of incision complications were analyzed between these two groups. RESULTS There were no significant differences in full load time, fracture healing time between these two groups (P > 0.05). The operation time, intraoperative blood loss, length of hospital stay, Ankle joint function score and postoperative incision complication rate in observation group were lower than those in control group (P < 0.05). CONCLUSION Small plate assisted anatomic plate is comparable to traditional double plate in the treatment of pilon fracture in terms of complete loading time, fracture healing time, but the former can shorten the operation time, reduce intraoperative blood loss and effectively reduce the incidence of postoperative complications.

Abstract
PURPOSE Ankle fracture-dislocations are among the most severe injuries, and the use of an external fixator as a recommended fixation method has some disadvantages. The aim of this study was to compare the clinical outcomes and complication rates of external and K-wire fixations in the treatment of ankle fracture dislocations. METHODS A total of 67 patients with ankle fracture-dislocations requiring temporary external or percutaneous K-wire fixation were included. The exclusion criteria were pilon fractures, open fractures, and those who required acute open reduction internal fixation (ORIF). The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, a 10-point visual analog scale (VAS) score (range 0-10), and complications before and after the definitive surgery were recorded. RESULTS A significant difference between the two groups was not observed for age, sex, affected side, fracture type, smoking status, or diabetes. The average AOFAS scores were 83.2 and 83.3, the median VAS scores were 3 and 3, and the complication rates were 32.4% and 6.7% in the external and K-wire fixation groups, respectively (p = 0.010). However, skin necrosis, re-dislocation of the ankle, surgical wound infection, and posttraumatic ankle osteoarthritis frequency were not significantly different between the groups, except for pin-sites infection (p = 0.036). CONCLUSION Ankle fracture-dislocations using percutaneous k-wire fixation showed a low rate of complications and favorable clinical outcomes. This method could be a good alternative treatment option for ankle fracture-dislocations.

Abstract
Aims Triplane ankle fractures are complex injuries typically occurring in children aged between 12 and 15 years. Classic teaching that closure of the physis dictates the overall fracture pattern, based on studies in the 1960s, has not been challenged. The aim of this paper is to analyze whether these injuries correlate with the advancing closure of the physis with age. Methods A fracture mapping study was performed in 83 paediatric patients with a triplane ankle fracture treated in three trauma centres between January 2010 and June 2020. Patients aged younger than 18 years who had CT scans available were included. An independent Paediatric Orthopaedic Trauma Surgeon assessed all CT scans and classified the injuries as n-part triplane fractures. Qualitative analysis of the fracture pattern was performed using the modified Cole fracture mapping technique. The maps were assessed for both patterns and correlation with the closing of the physis until consensus was reached by a panel of six surgeons. Results Fracture map grouped by age demonstrates that, regardless of age (even at the extremes of the spectrum), the fracture lines consolidate in a characteristic Y-pattern, and no shift with closure of the physis was observed. A second fracture map with two years added to female age also did not show a shift. The fracture map, grouped by both age and sex, shows a Y-pattern in all different groups. The fracture lines appear to occur between the anterior and posterior inferior tibiofibular ligaments, and the medially fused physis or deltoid ligament. Conclusion This fracture mapping study reveals that triplane ankle fractures have a characteristic Y-pattern, and acknowledges the weakness created by the physis, however it also challenges classic teaching that the specific fracture pattern at the level of the joint of these injuries relies on advancing closure of the physis with age. Instead, this study observes the importance of ligament attachment in the fracture patterns of these injuries.

Abstract
BACKGROUND About 10% of ankle fractures are located above the syndesmosis, which causes injury to the ligament structure of the syndesmosis. There is no consensus regarding when to allow weight-bearing on the operated limb of patients who suffered ankle fractures requiring intraoperative fixation. OBJECTIVE The aim of this study is the evaluation of radiographic parameters of syndesmosis reduction and fixation in patients with ankle fracture who underwent immediate protected weight-bearing (use of walking-boot and crutches). PATIENT AND METHODS Retrospective case series from January 2015 to December 2020. Evaluation of the tibiofibular clear space, tibiofibular overlap, and medial clear space in the preoperative x-ray, immediate postoperative, 3-, 6- and 12-month after syndesmosis fixation and rehabilitation with protected immediate weight-bearing with crutches and walking-boot. RESULTS Out of 137 ankle fractures 39 were included. There was no significant difference in the tibiofibular clear space between the immediate x-ray and after 12 months (4.5 mm ± 1.1 vs. 4.6 mm ± 1.8; p > 0.999). Tibiofibular overlap hasn't shown significant difference between immediate and 12-month x-ray (6.2 mm ± 2.6 vs. 6.6 mm ± 2.6; p > 0.999). Medial clear space also has shown no worsening from immediate to 12-month x-ray (3.1 mm ± 0.9 vs. 2.8 mm ± 0.9; p > 0.999). There were no fixation failure nor postoperative infection. CONCLUSION Immediate weight-bearing for patients with ankle fractures with syndesmosis injury and treated with intraoperative fixation with positioning screw proved to be safe with good maintenance of the reduction, no failures of the synthesis material observed and no reports of postoperative infection in the period. LEVEL 3 EVIDENCE: therapeutic retrospective case-series.

Abstract
INTRODUCTION Ankle fractures are one of the most frequent injuries managed by any trauma surgeon. Literature has shown that adequate reduction is of utmost importance to achieve satisfactory functional outcomes. However, malreduction rates remain high worldwide. The objective of the present study is to evaluate the quality of ankle fracture reduction in two major trauma centers in a large Brazilian city and to analyze the factors associated with malreduction METHODS: Epidemiologic data of 382 patients (189 men; 193 women) aged between 7 and 87 years who underwent osteosynthesis of the ankle in two trauma centers in a large Brazilian city. Electronic clinical records, preoperative and immediate postoperative radiographs in anteroposterior (AP), lateral and mortise views were evaluated. Pettrone's criteria were used to evaluate the quality of ankle fractures reduction. All radiographs were independently evaluated by two foot and ankle senior surgeons RESULTS: Overall, malreduction rate was 22.2%. Forty-seven (55.2%) fractures classified as malreduced had medial malleolar displacement The results showed three factors that significantly affected the quality of reduction (p<0.05), patients over 60 years, open fractures and fracture-dislocations. Patients aged over 60 years were twice more likely to have poor reduction of ankle fractures than younger ones. The risk of poor fracture reduction among those individuals with open fractures is 2.15 times greater than among patients with closed injuries. Fracture-dislocation imposed a 2.7 higher risk for malreduction DISCUSSION: We found a malreduction rate below most series previously published. Further results agree with the literature. Elderly people aged over 60 years, fracture dislocations and open fractures are associated with worse results, influencing the quality of the reduction, clinical outcomes, and the development of post-traumatic arthrosis CONCLUSION: Ankle fractures malreduction are associated with higher age, open fractures, and fracture-dislocations.

Abstract
BACKGROUND The fact that lateral malleolar fracture is accompanied by posterior malleolar fracture may adversely affect syndesmosis malreduction rates. We aimed to compare syndesmosis malreduction rates determined on postoperative radiographs between isolated lateral malleolar fractures and lateral malleolar fractures accompanied by posterior malleolar fractures. METHODS We retrospectively examined 128 operative patients: 73 with isolated lateral malleolar fractures (group L) and 55 with lateral + posterior malleolar fractures (group LP). In group LP, no patients received posterior fragment fixation. In both groups, indirect syndesmosis fixation was performed with a single screw after open reduction and internal fixation of the lateral malleolus. Patient age, sex, fracture side, fracture type (Lauge-Hansen and Danis-Weber classifications), Kellgren-Lawrence osteoarthritis classification, syndesmotic incongruency on postoperative radiographs, syndesmotic malreduction of postoperative fibula fracture, fracture union time, complication rates, accompanying injuries, and preoperative and postoperative radiographic syndesmotic measurements (tibiofibular overlap, tibiofibular clear space, medial clear space) were recorded, and the groups were compared. RESULTS Mean ± SD age was 44.32 ± 15.66 years in group L and 48.93 ± 14.03 years in group LP (P = .087). There were no significant differences in preoperative and postoperative tibiofibular distance, tibiofibular overlap, and medial clear space values between groups (P > .05). The prevalence of grade 2 fractures according to the Kellgren-Lawrence classification was significantly higher in group LP (P = .047). Postoperative syndesmosis malreduction was detected in 12 patients in group L and in nine in group LP (P = .991). CONCLUSIONS In lateral malleolar fractures accompanied by small-fragment posterolateral or avulsion-type posterior malleolar fractures, closed syndesmotic screw fixation does not cause syndesmosis malreduction.

Abstract
BACKGROUND With the advent of percutaneous plating techniques and anatomical locking plates, open plating combined with percutaneous plating may be a feasible option to reduce pilon fracture soft-tissue complications. The purpose of this study was to evaluate the outcomes of a combined open and percutaneous plating approach for the treatment of pilon fracture. METHODS Forty-two consecutive patients treated with a combined open and percutaneous plating approach between March of 2010 and February of 2020 for pilon fracture were reviewed retrospectively. The study population consisted of four female patients and 38 male patients with an average age of 47.5 years (range, 15-71 years). The mean follow-up duration was 25.7 months (range, 12-48 months). The combination of a small anterolateral approach and a small anteromedial approach (or a small direct medial approach) was used in all cases. A small posterolateral approach or a small posteromedial approach was added as necessary. RESULTS The average ranges of ankle sagittal motion and hindfoot coronal motion at 1 year postoperatively were 43.3° (range, 30°-60°) and 47.7° (range, 40°-55°), respectively. The mean 1-year postoperative visual analogue scale score and American Orthopaedic Foot and Ankle Society score were 0.90 (range, 0-4.0) and 94.5 (range, 78-100), respectively. All patients except one achieved bony union. The mean time to union (except in the one case of nonunion) was 4.5 months (range, 3-8 months). Minor wound breakdown occurred in five cases using combined approaches, but these eventually healed with local wound care. There were no major soft-tissue complications and no instances of deep infection. CONCLUSIONS A combined open and percutaneous plating approach is a feasible option for the treatment of pilon fracture. This combined plating technique involving a combination of a small anterolateral approach and a small anteromedial approach (or a small direct medial approach) yielded satisfactory outcomes without major soft-tissue complications.

Abstract
Bosworth fracture and dislocation is relatively rare, accounting for about 1% of ankle fractures. It is characterized by the proximal fibula fracture embedded in the posterolateral distal tibia. Due to an insufficient understanding of this fracture, it is easy to cause missed diagnosis and misdiagnosis in clinical practice. Due to the insertion of the fracture, it is challenging to perform closed reduction, and improper treatment is easy to cause complications. Surgical treatment is recommended for this type of fracture. In order to improve the understanding of orthopedic surgeons about Bosworth fracture and dislocation, this paper reports the diagnosis and treatment of 2 cases of Bosworth fracture and dislocation, and reviews the literature on Bosworth fracture's mechanism, diagnosis, classification, complications, and treatment options in recent years.

INTRODUCTION The aim of the study was to evaluate the safety of the modified posteromedial approach (MfPM) in the surgical management of complex ankle fractures in terms of local complications. METHODS Retrospective multicenter review of a series of malleolar fractures surgically treated by posterior ankle approaches between 2016 and 2022. Two approaches were used. In the MfPM group patients were placed in a prone position and the incision was made 1 cm medially to the Achilles tendon. In the posterolateral access (PL) group patients were placed in a prone or lateral decubitus position and the incision was made between the lateral malleolus and the Achilles tendon. Complications evaluated were divided into wound complications, infections, neuritis, vascular alterations and others. RESULTS 81 ankle fractures with a posterior malleolar fragment treated by open reduction and internal fixation were identified. 20 cases were approached through the MfPM approach and 61 through the PL access. The mean follow up was 18.60 months (range 4-78 months). In the MfPM group the local complication rate was 10% (2/10 patients), both corresponding to minor wound problems which required no surgical intervention. No infection or other neural or vascular complications were found. In the PL group a complication rate of 8,19% (5/61 patients) was found, all of them corresponding to minor wound problems which required no surgical intervention. No infection or other neural or vascular complications were found. There were no significant differences between the two approaches regarding postoperative local complications (z score 0.249 - P: 0.803). CONCLUSION The MfPM approach is safe and may become as readily used as the PL due to the low incidence of postoperative local complications, especially in fractures with a large fragment and posteromedial extension in which greater access to the posterior pilon can facilitate instrumentation for anatomic reduction and fixation.

Abstract
Ankle fractures are among the most common types of fractures seen in the United States. Few studies have analyzed the use of a locking compression plate (LCP) hook plate in the fixation of malleolar fractures. The goal of this study was to analyze postoperative outcomes in malleolar fractures fixed with a 3.5-mm LCP hook plate. A cohort of 74 patients with ankle fractures treated operatively with hook plates between 2011 and 2021 by a single orthopedic surgeon was retrospectively reviewed. Time to union, duration of non-weight bearing, final range of motion, postoperative complications, demographics, and comorbidities were recorded. A total of 66 patients fulfilled our inclusion criteria. There were 5 isolated medial malleolar, 34 bimalleolar, and 27 trimalleolar fractures. There were 46 women and 20 men with a mean age of 60.9±18.9 years. Fourteen patients had diabetes, 27 had osteoporosis, and 4 were current or former tobacco users. All patients achieved union, with a mean time to union of 10.9±5.3 weeks. The mean time to weight bearing was 50.2±18.4 days. The mean length of follow-up was 8.1±5.6 months. At final follow-up, mean dorsiflexion was 9.9°±4.3° and mean plantarflexion was 14.1°±5.1°. Six patients experienced postoperative complications such as surgical site infections and posttraumatic osteoarthritis. This study demonstrates that the use of a 3.5-mm LCP hook plate in the operative fixation of malleolar fractures has a high rate of union while maintaining low rates of postoperative complications.

Abstract
BACKGROUND Placement of clamp forceps along the transsyndesmotic (TS) axis reduces the risk of iatrogenic syndesmotic malreduction during ankle fracture surgery with tibiofibular diastasis. This study aimed to measure the difference between the TS axis and the axis determined by an intraoperative fluoroscopic technique using the center-center (CC) method. We also compared the values obtained when the CC method was performed at different heights from the tibial plafond. METHODS We evaluated the computed tomography scans of 150 patients with normal syndesmosis. The CC method was simulated using digitally reconstructed radiographs. The TS and CC axes were projected onto an axial computed tomographic image linked to digitally reconstructed radiography. The angle between the two axes (interaxis angle) and the distance between the intersection of these axes and the medial tibial cortex (interaxis distance) were measured. The procedures were performed 0, 10, and 20 mm proximal to the tibial plafond, and the measurements were compared among the different heights using a 1-way repeated-measures analysis of variance. RESULTS The TS axis was found to be externally rotated to the CC axis, with an interaxis angle of 8.5 degrees (SD, 6.8 degrees). The interaxis angle increased from 1.9 degrees at a height of 0 mm to a greater angle at higher heights (P < .001). The overall interaxis distance was 7.7 (SD, 6.3) mm, increasing from 2.0 mm at a height of 0 mm to a greater distance at higher heights (P < .001). CONCLUSION The TS axis was externally rotated relative to the CC axis, and the difference between the 2 axes was greater when the CC method was performed on the higher heights from the tibial plafond. To clamp the syndesmosis along the TS axis, the CC method should be applied close to the ankle joint. LEVEL OF EVIDENCE Level IV, case series.

Abstract
INTRODUCTION Controversy exists regarding the optimal management of AO/OTA 43. C3 pilon fractures. Open reduction and internal fixation (ORIF) is the gold standard treatment, but serious soft tissue and infectious complications have been previously reported. Minimally invasive strategies using hexapod ring fixation (HRF) with supplemental limited internal fixation have been used to reduce the incidence of complications. Previous studies have included heterogeneous types of pilon fractures, with non-comminuted injuries being more likely to be treated with ORIF and complex fractures receiving HRF treatment. To our knowledge, no studies have compared the complications and reoperation rates between ORIF and HRF exclusively for C3 fractures. METHODS Retrospective study comparing 53 patients treated for AO/OTA 43.C3 pilon fracture with ORIF or HRF in a trauma level I center with at least a two-year follow-up. Patients treated between January 2015 and January 2019 received ORIF and those treated between January 2019 and January 2021 received HRF. Complications were divided into two groups: minor (superficial infection and malalignment) and major (non-union, deep infection, and amputation). Reoperations, prevalence of ankle osteoarthritis, and requirement for ankle arthrodesis/total ankle replacement were registered. RESULTS We included 30 and 23 patients in the ORIF and HRF groups, respectively. The overall complication rate was similar in both groups, with 50% and 56,5% of the patients having complications in the ORIF and HRF groups, respectively (p:0,63). Minor complications were significantly more prevalent in the HRF group (p<0,001) whilst the ORIF group had a significantly higher rate of major complications (p<0,01). Superficial infections were highly prevalent in the HRF group (47,8%), as they were related to half-pin or K-wire infections. Deep infection was present only in the ORIF group, with 20% of the patients developing this major complication (p:0,03). Non-union rate, reoperations, ankle osteoarthritis, and the need for arthrodesis or ankle replacement showed no significant differences. CONCLUSION In AO/OTA 43.C3 fractures, HRF is safe and effective, achieving high union rates with a significantly lower rate of major complications compared to ORIF. According to our results, ORIF should be used cautiously for these types of fractures, considering the increased risk of deep infection.

Abstract
BACKGROUND We evaluated whether the quality of syndesmotic reduction affects the short-term clinical outcomes of flexible fixation in patients with a rotational ankle fracture. METHODS This study included 59 patients (32 men and 27 women) who underwent syndesmotic flexible fixation. The degree of syndesmotic reduction was evaluated on computed tomography (CT) images acquired within 3 days after surgery. We measured the divergence between anterior and posterior incisura at 1 cm above the distal tibial articular joint, then evaluated the degree of fibular rotation relative to the tibia. At 1 year after surgery, an objective clinical evaluation was performed using the American Orthopaedic Foot & Ankle Society (AOFAS) score, the visual analog scale (VAS), and the Foot and Ankle Outcome Score (FAOS). Additionally, repeat arthroscopy was performed during routine implant removal at nearly 1 year postoperatively. RESULTS Among 59 patients who underwent syndesmotic flexible fixation, 56 patients had syndesmotic stability on repeat arthroscopy. At 1 year postoperation, AOFAS, VAS, and FAOS scores were, respectively, 90, 2.0, and 94 in the accurate reduction group (n = 24) and 90, 1.0, and 94.5 in the malreduction group (n = 35). CONCLUSION Reduction quality after syndesmotic injury with flexible fixation, as determined by early postoperative CT imaging, did not affect patient prognosis. In this cohort, syndesmotic reduction and flexible fixation may produce good clinical outcomes in patients with syndesmotic injury and ankle fracture.

Abstract
PURPOSE The objectives of this study were to compare syndesmosis dislocation and ankle ligament stress after the fixation of the posterior malleolus fracture (PMF) with four different techniques by Finite Element Analysis (FEM). METHODS Four internal fixation techniques used for fixation of PMF were assessed by FEM: posterior one-third tubular 3.5 mm buttress plate (PP) with one screw (PP 1 screw), PP with two screws (PP 2 screws), two cannulated 3.5 mm lag screws in the anteroposterior (AP) direction (AP lag screws), and two posteroanterior (PA) cannulated 3.5 mm lag screws (PA lag screws). PMF with 30% fragment size was simulated through computational processing reconstructed from computed tomography (CT). The simulated loads of 700 N and 1200 N were applied to the proximal tibial end. The FEM evaluated the syndesmosis dislocation (mm) and stress values of the posterior tibiofibular ligament (PTFL) (in Kpa) and deltoid ligament (in Kpa) in the four mentioned subgroups. RESULTS We found that with a load of 700 N, syndesmosis dislocation varied from 6.5 to 7.9 mm, being the lowest and greatest for PA lag screw and PP 1 screw, respectively. In all groups was observed a greater dislocation in the syndesmosis at 1200 N of load. We observed that the stress values on the PTFL were lower for AP lag screws and PP 2 screws with 700 N and 1200 N, respectively. For both loads, PP 1 screw presented the greatest stress. Regarding the stress in the deltoid ligament, the AP lag screws presented the lowest stress for 700 N and PP 1 screw for 1200 N. For all fixation techniques, the syndesmosis displacement and ligament stresses were higher when 1200 N were imposed. CONCLUSION This study demonstrated that PMF fixed with lag screws presents greater stability in the distal tibiofibular syndesmosis and higher joint loadings promoted greater displacement and ligaments stress, regardless of the fixation technique. Besides, lower stress in the syndesmosis is accompanied by a greater load on the deltoid ligament.

Abstract
BACKGROUND Syndesmosis injuries occur in approximately 10% of all ankle fractures. The integrity of the deltoid ligament is important in the decision of surgical treatment of lateral malleolus fractures. METHODS Patients who were operated on for Weber B ankle fracture were evaluated retrospectively, and the relationship between tenderness around the medial malleolus and syndesmosis injury was investigated. Patients with visual analog scale, Foot and Ankle Ability Measure daily living, and sports activity scores in their files were included. This study enrolled 38 patients. The patients were divided into two groups. Group 1 consisted of patients with a medial space greater than 4 mm on preoperative radiographs and a positive intraoperative Cotton test, in which a syndesmosis screw was used. Group 2 consisted of patients with a medial space less than 4 mm on preoperative radiographs and negative intraoperative Cotton test, for whom no syndesmosis screw was used. RESULTS In 17 of 38 patients, syndesmosis screws were used because of intraopeative positive Cotton test. In 21 patients, the Cotton test was negative and the syndesmosis screw was not used. Comparing the groups statistically revealed no statistically significant difference in all scores. Tenderness around the medial malleolus was detected in two patients in group 2 and nine patients in group 1. A statistically significant difference was detected in terms of medial clear space values and tenderness around the medial malleolus between both groups. CONCLUSIONS The absence of tenderness around the medial malleolus in Weber B ankle fractures indicates no syndesmosis injury, whereas the presence of tenderness around the medial malleolus does not mean that there is a syndesmosis injury.

Abstract
CASE A 13-year-old healthy, nearly skeletally mature, female patient presented to an outpatient clinic after sustaining a bimalleolar ankle fracture-dislocation, which was subsequently treated with open reduction and internal fixation and casting. Postoperatively, the patient had significant limitations to ankle range of motion. Imaging revealed posterior tibiotalar impingement. The patient underwent arthroscopic debridement and osteoplasty, and she was able to return to previous levels of activity. CONCLUSIONS Complications from pediatric ankle fractures are rare, so further diagnostic workup is warranted for patients with persistent pain and limitations.

Abstract
OBJECTIVES Injury to the tibiofibular syndesmosis is a common complication of ankle fractures. Currently, it is challenging to determine the stability of the tibiofibular joint caused by ankle fractures during surgery. This study aims to establish a standardized method for dynamically evaluating the stability of the inferior tibiofibular joint under intraoperative ultrasound and assess its utility in surgery, thereby assisting in determining the necessity for fixation of the inferior tibiofibular joint after fracture reduction and fixation. METHODS The stability of the inferior tibiofibular joint was assessed using an intraoperative ultrasonic external rotation stress test, with a torque set at 7.2 N·m. The measured parameters included the width of the inferior tibiofibular space in neutral (N) and external rotation (E) positions, stretch ratio (E/N), and injured/healthy side stretch ratio (I/H). Patients with Weber B or C type ankle fractures were selected as participants. RESULTS For the case with Weber C fracture, the N measurement was 4.22 mm after fracture fixation, while E measured 5.77 mm and E/N ratio was 1.37, which were larger than those on the healthy side (N: 4.17, E: 4.50, E/N:1.08), with an I/H ratio of 1.27. Intraoperative X-ray revealed instability of the inferior tibiofibular joint. After inserting a tibiofibular screw, the N measurement was 4.20 mm, while the E measurement recorded 4.32 mm, resulting in an E/N ratio of 1.03 and an I/H ratio of 0.95, indicating improved joint stability. For the Weber B fracture case, the N measurement was 3.55 mm after fracture fixation, while E measured 3.98 mm and the E/N ratio was 1.12, slightly lower than those on the healthy side (N: 3.94, E: 4.47, E/N: 1.13), with an I/H ratio of 0.99. The intraoperative X-ray revealed stability of the inferior tibiofibular joint. Therefore, no further fixation was performed on it. CONCLUSION Standardized intraoperative ultrasound stress test allows for real-time, dynamic assessment of the stability of the inferior tibiofibular joint after ankle fracture reduction and fixation, which can help guide the fixation of the inferior tibiofibular joint, thereby reducing the risk of postoperative traumatic arthritis.

Abstract
BACKGROUND Malunited posterior pilon fractures with talus dislocation (mPPFtd) are rare and there are no appropriate treatment strategies. The purpose of this study was to introduce a stepped strategy featuring preliminary soft tissue management according to the Ilizarov principle and delayed open reduction and internal fixation (ORIF) through a modified posteromedial approach to overcome rigid soft tissue contracture. METHOD From February 2015 to August 2021, 12 selected patients with mPPFtd who were treated with the staged protocol (Group A) were retrospectively analysed. The clinical and radiographic outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, the visual analogue scale (VAS) score, and the Burwell-Charnley score. Moreover, this case series was compared with some cases of fresh fracture (Group B) in patients that had the same baseline data from our previous study. RESULTS In Group A, the average length of time between the date of injury and the date of surgery was 4.8 ± 3.3 months. The average time to external fixator distraction, as the first-stage treatment, was 13.4 ± 1.0 days. In the second stage of ORIF, the posterosuperior dislocation of the talus was corrected with osteotomy and leverage manoeuvres. According to the Burwell-Charnley score system, the reduction quality was excellent in 9 cases and good in 3 cases. After a mean follow-up of 3.8 ± 2.1 years, there were no infections, wound healing problems, or nerve injuries in our cohort, and union was observed in all fractures without a loss of reduction. The baseline data of the two groups were not significantly different (p>0.05). The mean AOFAS score in Group A was 85.0 ± 10.5 and that in Group B was 95.4 ± 6.1 (p<0.05). The mean VAS score in Group A was 1.7 ± 1.4 and that in Group B was 0.7 ± 0.9 (p<0.05). CONCLUSION A staged surgical treatment strategy characterized by soft tissue management will improve the treatment of mPPFtd and produce satisfactory clinical outcomes.

Abstract
OBJECTIVE To correlate patient-specific and surgeon-specific factors with outcomes after operative management of distal intra-articular tibia fractures. DESIGN Retrospective cohort study. SETTING 3 Level 1 tertiary academic trauma centers. PATIENTS/PARTICIPANTS The study included a consecutive series of 175 patients with OTA/AO 43-C pilon fractures. MAIN OUTCOME MEASUREMENTS Primary outcomes included superficial and deep infection. Secondary outcomes included nonunion, loss of articular reduction, and implant removal. RESULTS The following patient-specific factors correlated with poor surgical outcomes: increased age with superficial infection rate ( P < 0.05), smoking with rate of nonunion ( P < 0.05), and Charlson Comorbidity Index with loss of articular reduction ( P < 0.05). Each additional 10 minutes of operative time over 120 minutes was associated with increased odds of requiring I&D and any treatment for infection. The same linear effect was seen with the addition of each fibular plate. The number of approaches, type of approach, use of bone graft, and staging were not associated with infection outcomes. Each additional 10 minutes of operative time over 120 minutes was associated with an increased rate of implant removal, as did fibular plating. CONCLUSIONS While many of the patient-specific factors that negatively affect surgical outcomes for pilon fractures may not be modifiable, surgeon-specific factors need to be carefully examined because these may be addressed. Pilon fracture fixation has evolved to increasingly use fragment-specific approaches applied with a staged approach. Although the number and type of approaches did not affect outcomes, longer operative time was associated with increased odds of infection, while additional fibular plate fixation was associated with higher odds of both infection and implant removal. Potential benefits of additional fixation should be weighed against operative time and associated risk of complications. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
INTRODUCTION Trimalleolar fractures are difficult to treat and malreduction can lead to functional impairment. Involvement of the posterior malleolus has a poor predictive value. Current computed-tomography (CT)-based fracture classifications led to an increase in fixation of the posterior malleolus. The aim of this study was to describe the functional outcome after a two-stage stabilisation with direct fixation of the posterior fragment in trimalleolar dislocation fractures. MATERIALS AND METHODS In a retrospective study, all patients presenting with a trimalleolar dislocation fracture, an available CT scan, and a two-stage operative stabilisation including the posterior malleolus by a posterior approach were included. All fractures were treated with initial external fixator and delayed definitive stabilisation including fixation of the posterior malleolus. Next to clinical and radiological follow-up, outcome measures (Foot and Ankle Outcome Score (FAOS), Numeric Rating Scale (NRS), Activity of Daily Living (ADL), Hulsmans implant removal score) and complications were analysed. RESULTS Between 2008 and 2019, of 320 trimalleolar dislocation fractures, 39 patients were included. Mean follow-up was 49 months (standard deviation (SD) 29.7, range 16-148). Mean age was 60 years (SD 15.3, 17-84) with 69% female patients. The mean FAOS was 93/100 (SD 9.7, 57-100), NRS 2 (interquartile range (IQR) 0-3) and ADL 2 (IQR 1-2). Four patients showed a postoperative infection, three re-operations had to be performed and implants were removed in 24 individuals. CONCLUSION A two-stage procedure of trimalleolar dislocation fractures with in-direct reduction and fixation of the posterior tibial fragment through a posterior approach leads to good functional outcome scores with a low rate of complications.
