ankle syndesmosis

INTRODUCTION: Results of operative fixation for ankle fractures had been suboptimal, with cases of posttraumatic osteoarthritis occurring following the surgeries. Intra-articular injuries have been suggested as the cause of this problem. This case report aims to present an ankle pilon fracture Ruedi Allgower type II case treated with percutaneous fixation and arthroscopy evaluation. PRESENTATION OF CASE: Female, 17 years old, complained of pain and swelling at the right ankle...

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...

BACKGROUND: If tibiofibular syndesmotic injury is undetected, chronic instability may lead to persistent pain and osteoarthritis. So far, no reliable diagnostic method has been available. The primary objectives of this study were to determine whether defined lesions of the syndesmosis can be correlated with specific tibiofibular joint displacements caused by external rotational torque and to compare the performance of bilateral external torque computed tomography (BET-CT) and arthroscopy...

When treating ankle fractures, the question of syndesmosis complex involvement often arises. So far, there is no standardized method to reliably detect syndesmosis injuries in the surgical treatment of ankle fractures. For this reason, an intraoperative syndesmosis-test-tool (STT) was developed and compared to the recommended and established hook-test (HT). Tests were performed on cadaveric lower legs (n = 20) and the diastasis was visualized by 3D camera. Tests were performed at 50, 80, and 100 N in native conditions and four instability levels...

BACKGROUND: The posterior malleolus component of the trimalleolar ankle fracture has posed a controversial topic for diagnostic imaging and surgical management. Preoperative computed tomography (CT) scans are used to better appreciate fracture morphology and may affect management techniques. No prior study has investigated the trend in preoperative CT scan use and the rates of posterior and syndesmotic fixation for trimalleolar injuries. METHODS: This retrospective cohort study evaluated the use of preoperative CT scans and the rates of posterior and syndesmotic fixation for trimalleolar ankle fractures over a 10-year period at an adult level 1 trauma center...

BACKGROUND: Non-invasive diagnosis of distal tibiofibular syndesmosis instability (DTSI) was a great challenge to clinicians. We designed a new method, the Standing on single foot-Binding test, and investigated the accuracy of the test in the diagnosis of distal tibiofibular syndesmosis instability in adults with a history of ankle injury. METHODS: 85 participants with ankle injury were subjected to the Standing on single foot-Binding test, MRI and palpation to detect the distal tibiofibular syndesmosis instability (DTSI) and the findings were compared with ankle arthroscopic results...

BACKGROUND: Distal tibiofibular syndesmotic injuries, often misdiagnosed, can lead to substantial morbidity. This study utilized postmortem computed tomography (PMCT) to define normal syndesmotic relationships in 131 subjects. METHODS: Three parameters were measured: fibular rotation (FR), sagittal translation (ST), and incisura depth (ID). RESULTS: Interobserver reliability was excellent for FR and ID but moderate for ST. Anatomical variability was wide, with FR ranging from -0...

INTRODUCTION: Surgery is widely recognised as the treatment of choice for suprasyndesmotic ankle fractures, because of the assumption that these injuries yield instability of the ankle joint. Stability assessment of ankle fractures using weightbearing radiographs is now used regularly to guide the treatment of transsyndesmotic and infrasyndesmotic ankle fractures. Patients with a congruent ankle joint on weightbearing radiographs can be treated non-operatively with excellent results. Weightbearing radiographs are, however, rarely performed on suprasyndesmotic fractures due to the assumed unstable nature of these fractures...

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...

Lateral ankle sprains and instability are an increasingly identified pain point for patients, accounting for 20 to 25% of musculoskeletal injuries. Lateral ankle injuries are especially concerning given the propensity for patients to develop chronic lateral ankle instability and for the high risk of reinjury on an unstable ankle. With the complex articulation of the tibiofibular syndesmosis, subtalar, and talocrural joints, pinpointing ankle dysfunction remains difficult. Multiple reviews have evaluated management and diagnosis of lateral ankle instability, but with newer treatment options available, a more comprehensive assessment of the current literature was conducted...

Background Ankle sprains and fractures rank among the most commonly occurring musculoskeletal injuries and hold significant relevance in current medical practice. Accurate information regarding these injuries is crucial for their effective treatment. This study aimed to explore the viability of utilizing ankle lateral radiographs to evaluate syndesmosis in both emergency settings and operating theatres. Methods This randomized retrospective clinical study involved the analysis of 150 ankle lateral radiographs (54 males and 96 females) from patients who presented at our emergency department with suspected ankle injuries...

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...

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)...

Background and Objectives: While numerous studies have been conducted on syndesmotic screw management following distal tibiofibular diastasis repair, a clear consensus remains unclear. This research aims to evaluate whether the postoperative removal of syndesmotic screws leads to improved patient outcomes, specifically in quality of life, mobility, and daily living activities, and whether it offers a cost-effective solution. Materials and Methods: Patients with a history of unimalleolar or bimalleolar ankle fractures, classified according to the Danis-Weber and Lauge-Hansen systems, were included...

INTRODUCTION: The current standard treatment for ankle syndesmosis injury is static screw fixation. Dynamic fixation was developed to restore the dynamic function of the syndesmosis. The purpose of this study was to determine that which of static screw fixation and dynamic fixation is better for treatment of ankle syndesmosis injury in pronation-external rotation fractures. MATERIALS AND METHODS: Thirty patients were treated with dynamic fixation (DF group) and 28 patients with static screw fixation (SF group)...

BACKGROUND: To retrospectively evaluate the clinical outcomes of patients treated for syndesmotic injuries with an all-suture construct technique and compare their patient reported outcome scores with historically published outcomes of syndesmotic injuries fixed with suspensory suture buttons. METHODS: This was a retrospective case series of patients treated at a Level 1 Trauma Center from May 1, 2018, to June 30, 2022. Ten patients aged 18 and older with unstable syndesmotic injuries treated with all-suture repair...

BACKGROUND AND OBJECTIVES: This longitudinal study investigated the correlation between imaging findings and self-reported questionnaire outcomes in patients with tibiofibular diastasis, exploring the effects of surgical screw removal versus conservative treatment. This study was conducted at "Victor Babes" University of Medicine and Pharmacy in Timisoara between 2018 and 2023. MATERIALS AND METHODS: The study involved 85 patients in the screw removal group and 44 in the conservative group, assessed at 2 and 6 months post-surgery, answering the SF-36, HADS, and WHOQOL questionnaires...

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...

Background Screw fixation continues to be a commonly used treatment for syndesmotic disruption; however, screw breakage remains a complication post-fixation. Despite this complication, investigation on the variability of surgical placement in conjunction with syndesmotic screw characteristics affecting breakage has not been fully elucidated. The purpose of this study is to compare patients with syndesmotic screw breakage versus those with intact screws based on surgically controlled variables. Methods A total of 176 patients and 260 syndesmotic screws were included in the study, 88 patients each with and without broken syndesmotic screws...

Hallux valgus (HV) is a common deformity of the foot. Its postoperative recurrence is not uncommon and is closely related to the recurrence of its underlying metatarsus primus varus (MPV) deformity. The syndesmosis procedure uses 1-2 intermetatarsal cerclage sutures to realign the first metatarsal and then induces a biological bonding between the two metatarsals to prevent the MPV deformity from recurring. This radiological study aimed to assess its effectiveness in long-term MPV and HV deformities recurrence prevention...
