Posterior malleolar

AIMS: Posterior malleolar (PM) fractures are commonly associated with ankle fractures, pilon fractures, and to a lesser extent tibial shaft fractures. The tibialis posterior (TP) tendon entrapment is a rare complication associated with PM fractures. If undiagnosed, TP entrapment is associated with complications, ranging from reduced range of ankle movement to instability and pes planus deformities, which require further surgeries including radical treatments such as arthrodesis. METHODS: The inclusion criteria applied in PubMed, Scopus, and Medline database searches were: all adult studies published between 2012 and 2022; and studies written in English...

INTRODUCTION: Treatment of posterior malleolar (PM) ankle fractures remains controversial. Despite increasing recommendation for small PM fragment fixation, high quality evidence demonstrating improved clinical outcomes over the unfixated PM is limited. We describe the long term clinical and radiographical outcomes in younger adult patients with PM ankle fractures managed without PM fragment fixation. MATERIAL AND METHODS: A retrospective cohort study was performed on PM ankle fracture patients aged 18-55 years old admitted under our orthopaedic unit between 1st of April 2009 and 31st of October 2013...

BACKGROUND: Ankle fractures are among the most common lower limb fractures. There is no agreement about the best treatment for these fractures. This study compared the short-term results of screw and plate fixation methods. METHODS: In this prospective study, 32 patients that underwent screw fixation for posterior malleolar fracture and 32 patients that underwent plate fixation for posterior malleolar fracture were assessed 1, 3, and 6 months after surgery. RESULTS: The mean age in group 1 (screw fixation) and group 2 (plate fixation) was 32...

BACKGROUND: For the temporary treatment of ankle fracture dislocations (AFDs), previous studies indicate higher rates of secondary loss of reduction (LOR) with splint immobilization, prompting consideration for expanding indications for external fixation (ExFix). However, these studies did not investigate the influence of fracture morphology to further improve patient selection. The aim of this study was to investigate the influence of Lauge-Hansen injury type on the LOR rate in bimalleolar or trimalleolar AFDs for temporary cast vs ExFix immobilization...

AIMS: The optimal management of posterior malleolar ankle fractures, a prevalent type of ankle trauma, is essential for improved prognosis. However, there remains a debate over the most effective surgical approach, particularly between screw and plate fixation methods. This study aims to investigate the differences in outcomes associated with these fixation techniques. METHODS: We conducted a comprehensive review of clinical trials comparing anteroposterior (A-P) screws, posteroanterior (P-A) screws, and plate fixation...

Posterior pilon variant ankle fractures (PPVF) are a unique subtype of posterior malleolar fractures which have been a source of controversy and confusion in recent years. There has not been a thorough literature review previously written on the topic. Database searches of PubMed and Embase were conducted from inception until June 2023. The key words included "pilon variant," "posterior pilon variant," and "posterior pilon" fractures. Outcomes were evaluated by union time, rates of delayed union, nonunion, malunion, and complication...

BACKGROUND: Posterior pilon fracture is speculated to occur by a combination of rotation and axial load, which makes it different from rotational posterior malleolar fracture or pilon fracture, but is not validated in vitro. The aim of the current study is to investigate the injury mechanisms of posterior pilon fracture on cadaveric specimens. METHODS: Eighteen cadaveric specimens were mounted to a loading device to undergo solitary vertical loading, solitary external rotational loading, and combined vertical and external rotational loading until failure, in initial position of plantarflexion with or without varus...

OBJECTIVES: The knowledge of different types of ankle fractures based on plain radiographs and computed tomography (CT) images can help improve patients' management. METHODS: This cross-sectional study assessed the plain radiographs and CT images of 1,000 consecutive patients observed in an emergency department between March 2015 and March 2020. Fractures were labeled as uni-, bi-, or trimalleolar. Malleolar fractures were classified into medial, lateral, and posterior ones based on Herscovici, Danis-Weber, and Mason and Molloy classifications, respectively...

Background Ankle fractures constitute 10% of all traumatic fractures in clinical practice. Concurrent tibiotalar dislocations form 21-36% of all ankle fractures. Although mechanism of injury is similar to non-dislocated ankle fractures, fracture-dislocations cause more extensive bone and soft tissue damage. Treatment is a challenge for orthopedic surgeons due to concomitant pathologies. It is associated with malreduction, chronic pain and most importantly, posttraumatic osteoarthritis. We aimed to investigate the relationship between ankle osteoarthritis radiographic stage and clinical outcomes...

BACKGROUND: Treatment of posterior malleolar fracture with plate or screw fixation is still controversial. Plate fixation is considered to have better stability but more soft tissue damage; screw fixation is less invasive and may yields lesser blood loss and surgery time. We conducted this meta-analysis to explore intraoperative and postoperative efficacy between plate and screw fixation in posterior malleolar fractured patients. METHODS: PubMed, Cochrane, Embase, Scopus and Chinese National Knowledge Infrastructure databases were searched in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines...

IMPORTANCE: Unstable ankle fractures are routinely managed operatively. However, because of soft tissue and implant-related complications, recent literature has reported on the nonoperative management of well-reduced medial malleolus fractures after fibular stabilization, but with limited evidence supporting the routine application. OBJECTIVE: To assess the superiority of internal fixation of well-reduced (displacement ≤2 mm) medial malleolus fractures compared with nonfixation after fibular stabilization...

BACKGROUND: Ankle fractures are common lesions of the lower limbs. Approximately 40% of ankle fractures affect the posterior malleolus (PM). Historically, PM osteosynthesis was recommended when PM size in X-ray images was greater than 25% of the joint. Currently, computed tomography (CT) has been gaining traction in the preoperative evaluation of ankle fractures. AIM: To elucidate the similarity in dimensions and to correlate PM size in X-ray images with the articular surface of the affected tibial plafond in the axial view on CT (AXCT) of a PM fracture...

INTRODUCTION: Syndesmotic injury in trimalleolar fracture is necessary to address intraoperatively by stability test, as it affects post-operative functional outcomes. Most of syndesmotic injuries are stable after fixation of the posterior malleolus, but in rare cases, syndesmosis is not stable after adequate fixation. In those rare conditions, we have to fix syndesmosis by corticocancellous (CC) screw throw lateral fibula plate. We emphasize this complex problem and offer solutions to overcome it...

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...

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...

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...

There has been a paradigm shift towards fixing the posterior malleolus in trimalleolar ankle fractures. This study evaluated whether a surgeon's preference to intraoperatively flip or not flip patients from prone to supine for medial malleolar fixation following repair of fibular and posterior malleoli impacted surgical outcomes. A retrospective patient cohort treated at a large urban academic center and level 1 trauma center was reviewed to identify all operative trimalleolar ankle fractures initially positioned prone...

BACKGROUND: The innate shape characteristics of the hindfoot bones alter the loading conditions of the foot and thus may be associated with an increased risk of developing varus ankle osteoarthritis (OA). This study aimed to clarify the innate morphological patterns of the hindfoot bones that may be associated with ankle OA by analyzing the differences between the bone morphology of the non-affected side of patients with unilateral varus ankle OA and that of healthy participants. METHODS: In this case-control study, computed tomography images were used to develop three-dimensional models of three hindfoot bones (distal tibia with fibula, talus, and calcaneus) from 23 non-affected sides of patients with radiography-diagnosed unilateral ankle OA and 22 healthy control participants...

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...

Introduction: We investigated the biomechanical behaviour of different fixations of the tibial posterior malleolus (TPM), simulating distinct situations of involvement of the tibiotalar articular surface (TTAS) through a finite element model (FEM). Material and methods: A 3D computer-aided design model of the left ankle was obtained. The materials used were divided according to their characteristics into ductile and non-ductile, and all materials were assumed to be linear elastic, isotropic, and homogenous...
