A too-long anterior process (TLAP) of the calcaneus is an elongated anteromedial process of the calcaneus impinging the navicular or the talar head. TLAP can cause recurrent ankle sprain, peroneal muscle spasm, or persistent tarsal pain in adolescents. Arthroscopic resection is indicated if the symptoms do not respond to conservative treatment. It has the advantage of assessment of completeness of bone resection and treatment of associated lesions of the adjacent joints. The purpose of this technical note is to report an arthroscopic approach of the resection of the TLAP with the lateral midtarsal portal as the viewing portal...

The aim of this work is to provide a computational tool for the investigation of ankle mechanics under different loading conditions. The attention is focused on the biomechanical role of ankle ligaments that are fundamental for joints stability. A finite element model of the human foot is developed starting from Computed Tomography and Magnetic Resonance Imaging, using particular attention to the definition of ankle ligaments. A refined fiber-reinforced visco-hyperelastic constitutive model is assumed to characterize the mechanical response of ligaments...

Ankle arthrodesis is performed to eliminate pain due to end-stage osteoarthritis, regardless of etiology. This procedure remains the reference standard treatment for end-stage ankle arthritis, despite recent advancements in total ankle replacement. The objective of the present study was to retrospectively evaluate the radiographic and clinical fusion rates and time to bony fusion for patients who underwent ankle arthrodesis using an anterior approach with a single column locked plate construct versus crossed lag screws...

BACKGROUND: The literature on ankle valgus development after procuring non-vascularised fibular grafts in children is still scanty. The non-vascularised fibular graft has distinction of fibular regeneration occurring at the donor site. MATERIAL AND METHODS: We retrospectively analysed the valgus deformities at the donor leg following harvest of non-vascularised fibular graft to determine the various contributing factors in growing children. All these patients had minimum two years post index procedure follow up...

BACKGROUND: Mobile-bearing total ankle replacement (TAR) enables motion at the tibial implant-polyethylene insert interface. This motion could lead to coronal translation of the talus relative to the tibia and may affect radiographic outcome. We aimed to assess the translation of the talus before and after mobile-bearing TAR to determine whether translation of the talus after TAR is associated with coronal plane alignment of the lower limb and hindfoot as well as to investigate the complications associated with talar translation...

BACKGROUND: Hindfoot alignment on 2D radiographs can present anatomical and operator-related bias. In this study, software designed for weightbearing computed tomography (WBCT) was used to calculate a new 3D biometric tool: the Foot and Ankle Offset (FAO). We described the distribution of FAO in a series of data sets from clinically normal, varus, and valgus cases, hypothesizing that FAO values would be significantly different in the 3 groups. METHODS: In this retrospective cohort study, 135 data sets (57 normal, 38 varus, 40 valgus) from WBCT (PedCAT; CurveBeam LLC, Warrington, PA) were obtained from a specialized foot and ankle unit...

BACKGROUND: The Root model of normal and abnormal foot function remains the basis for clinical foot orthotic practice globally. Our aim was to investigate the relationship between foot deformities and kinematic compensations that are the foundations of the model. METHODS: A convenience sample of 140 were screened and 100 symptom free participants aged 18-45 years were invited to participate. The static biomechanical assessment described by the Root model was used to identify five foot deformities...

Peripheral talus fractures include injuries to the lateral process, posteromedial talar body, and talar head. These injuries are rare and are often missed. Nonunion with conservative treatment is high and excision can lead to joint instability, rapid arthrosis, and earlier need for arthrodesis. Open reduction internal fixation of most peripheral talus fractures is critical to achieving a good outcome. Open reduction leads to more rapid union and ability to mobilize the ankle and subtalar joints, quicker revascularization of the talus, and lower rates of arthrosis...

Anterior ankle snapping syndrome is rare. Snapping of the extensor digitorum longus due to attenuated inferior extensor retinaculum and snapping due to hypertrophied or low-lying peroneal tertius muscle have been reported. We reported a new mechanism of anterolateral snapping due to a hypertrophied talar head. Anterolateral snapping ankle can be revealed by active dorsiflexion and plantarflexion of the ankle with the foot inverted. Foot inversion will tension the inferior extensor retinaculum and uncover the dorsolateral prominence of the talar head...

AIMS: A failed total ankle arthroplasty (TAA) is often associated with much bone loss. As an alternative to arthrodesis, the surgeon may consider a custom-made talar component to compensate for the bone loss. Our aim in this study was to assess the functional and radiological outcome after the use of such a component at mid- to long-term follow-up. PATIENTS AND METHODS: A total of 12 patients (five women and seven men, mean age 53 years; 36 to77) with a failed TAA and a large talar defect underwent a revision procedure using a custom-made talar component...

Osteochondral lesions of the talus (OLT) occur in up to 70% of acute ankle sprains and fractures. OLT have become increasingly recognized with the advancements in cartilage-sensitive diagnostic imaging modalities. Although OLT may be treated nonoperatively, a number of surgical techniques have been described for patients whom surgery is indicated. Traditionally, treatment of symptomatic OLT have included either reparative procedures, such as bone marrow stimulation (BMS), or replacement procedures, such as autologous osteochondral transplantation (AOT)...

Pedography provides excellent visualization of the footprint. However, the correlation between the footprint images and radiographic measures has not been thoroughly evaluated. Therefore, the objectives of our study were to examine the correlation between the pedography-based measures of foot morphology and radiographic measurements and to propose reference values for the diagnosis of flatfoot using footprint imaging. The plantar footprints of 100 right feet were photographed using a pedography standing platform...

INTRODUCTION: Non-or partial weight bearing is frequently the standard treatment after peri-articular lower extremity fractures. Displaced talar neck fractures are severe injuries compromising vascularity of the corpus and consequently are at risk for non-union and avascular necrosis, the main reason to restrict weight bearing for up to three months according to most literature.

BACKGROUND: Osteochondral lesions of the talus (OLTs) are amongst the most common foot and ankle disorders. Varus ankle malalignment causes stress concentration on medial side of the joint, resulting in OLTs and osteoarthritis. For large symptomatic OLTs (>10 mm), Osteochondral autograft transplantation is usually recommended. This article highlights biplanar distal tibial osteotomy as an approach and management for patients with concomitant large OLTs and varus ankle malalignment...
