The present study was to determine the characteristics of the ankle skeletal structure in patients with talus Hepple V type. We conducted a retrospective study on the skeletal structure of the talus in 110 patients with Hepple V osteochondral lesions of the talus and in control participants. The radiographic measurements taken include the following: in the coronal plane - depth of talus frontal curvature, length of the lateral and medial malleolus; in the sagittal plane - radius and height of talus, angle of tibial lateral surface, tibiotalar sector, and vertical neck angle...

BACKGROUND: Diabetic peripheral neuropathy (DPN) is a common and debilitating complication of type 2 diabetes mellitus (T2DM). Early detection and prompt institution of appropriate therapy could prevent undesirable outcomes such as paresthesia, pain, and amputation. Although the gold standard for diagnosing DPN is nerve conduction studies, high-resolution peripheral nerve ultrasonography may serve as a noninvasive and low-cost alternative for diagnosing and staging DPN. This study investigated the clinical utility of sonographic posterior tibial nerve cross-sectional area (PTN CSA) for diagnosing DPN in individuals with T2DM...

This study aimed to enhance our understanding of the mechanical behavior of tibiotalar joint articular cartilages in the presence of varus deformity using finite element analysis (FEA) applied to patient-specific models. METHODS: Two personalized ankle models, one healthy and another with varus deformity, were created based on CT scan images...

OBJECTIVE: To investigate the effectiveness of a new hook-shaped anatomical locking plate in the treatment of Danis-Weber type A lateral malleolus fractures. METHODS: A retrospective analysis was performed on the clinical data of 45 patients with Danis-Weber type A lateral malleolus fractures who met the selection criteria between November 2020 and November 2022. According to the surgical methods, they were divided into the observation group (treated with the new hook-shaped anatomical locking plate, 23 cases) and the control group (treated with the conventional lateral malleolus anatomical locking plate, 22 cases)...

BACKGROUND: Some children and adolescents can develop persistent pain and instability following inversion injuries of the ankle. In these cases, imaging exams could reveal small bone fragments distal to the lateral malleolus. For these patients, regular conservative treatment may not be successful, requiring additional management, which can include surgical treatment. This study aimed to present the short-to-midterm functional and clinical outcomes of a series of 12 pediatric and adolescent patients who underwent ligament repair surgery due to chronic instability associated with the presence of osseous components in the lateral ligaments...

INTRODUCTION: The standard surgical procedure for unstable ankle fractures is fixation of the lateral malleolus with a plate and screws. This method has a high risk of complications, especially among patients with fragile skin conditions. The aim of this study was to estimate the re-operation rates and identify complications in patients with an unstable ankle fracture, surgically treated with an intramedullary screw or rush pin. MATERIALS AND METHODS: We identified all patients who were surgically treated with either a 3...

It is essential to understand the considerable variations in bifurcation patterns of the tibial nerve (TN) and its peripheral nerves at the level of the tarsal tunnel to prevent iatrogenic nerve injury during surgical nerve release or nerve block. A total of 16 ankles of 8 human cadavers were dissected to investigate the branching patterns of the TN, using 2 imaginary lines passing through the tip of the medial malleolus (MM) as reference lines. Bifurcation patterns and detailed information on the relative locations of the medial plantar, lateral plantar, medial calcaneal, and inferior calcaneal nerves to the reference lines were recorded...

Fractures of the lateral malleolus are common in children. Isolated lesions of the distal fibula physis commonly comprise nondisplaced or minimally displaced fractures. An isolated, completely displaced epiphysiolisthesis of the distal fibula is an extremely rare lesion. This study introduces the case of an 11-year-old boy presenting an extremely rare lesion of an isolated, completely displaced distal fibular epiphysis that was difficult to diagnose on X-ray. Initial radiographic examination of the injured ankle showed normal configuration of the tibia and fibula on AP projection, with soft tissue swelling of the lateral malleolus...

Additionally, patients' ability to return to activity following surgical treatment of these fractures was also analysed. Materials and methods Retrospective analysis of surgically treated talus fractures at the PSG Institute of Medical Sciences and Research from 2012 to 2015. The fractures were classified as neck and body fractures...

BACKGROUND: The pendulum test is a quantitative method used to assess knee extensor spasticity in humans with spinal cord injury (SCI). Yet, the clinical implementation of this method remains limited. The goal of our study was to develop an objective and portable system to assess knee extensor spasticity during the pendulum test using inertial measurement units (IMU). METHODS: Spasticity was quantified by measuring the first swing angle (FSA) using a 3-dimensional optical tracking system (with external markers over the iliotibial band, lateral knee epicondyle, and lateral malleolus) and two wireless IMUs (positioned over the iliotibial band and mid-part of the lower leg) as well as a clinical exam (Modified Ashworth Scale, MAS)...

Surgical repair of acute or chronic lateral instability of the ankle may be unsuccessful in the presence of associated anterior fibulotalar ligament (AFTL) and calcaneofibular ligament (CFL) injury. This Technical Note presents an arthroscopic double-row repair technique of the AFTL associated with suture tape augmentation of the CFL. The patient is in the supine position with the ankle hanging over the edge of the surgical table. The anteromedial portal is created inside the anterior tibial tendon, and the anterolateral portal is created under arthroscopic control...

However, no evidence is available to support that this level is appropriate for evaluating retromalleolar groove morphology. PURPOSE: To assess the influence of the level of axial computed tomography (CT) scans on the assessment of retromalleolar groove morphology. STUDY DESIGN: Cross-sectional study; Level of evidence, 3...

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...

A man in his 40s presented with an incidental finding of an osteolytic bone lesion. He sustained an ankle injury while inline skating, fracturing his lateral malleolus. Besides the fracture, radiographic imaging on the day of the injury incidentally revealed a well-defined solitary osteolytic lesion with a sclerotic rim within the right calcaneus. MRI showed an intraosseous, fat-containing lesion with focal contrast enhancement, assessed as an intraosseous lipoma with central necrosis. In the pathological analysis of a sample of the lesion an intraosseous myo lipoma of the calcaneus was found-an unexpected and extraordinary finding...

BACKGROUND: Preoperative localisation of perforators aids in easy intraoperative dissection. Infrared thermography is a simple, safe, and effective tool with a short learning curve that is useful in identifying perforators. It has been found to have a high concordance rate when compared with computed tomography angiography and is useful in identifying arterial perforators in the leg. OBJECTIVES: To create a thermographic map of arterial perforators in the leg and to determine the correlation between the number of perforators identified and the length of the leg...
