Purpose: Describe the surgical technique of talocalcaneal coalition resection using live CT navigation. Methods: A ten-year-old female with left talocalcaneal coalition hindfoot pain refractory to conservative management underwent surgical coalition resection using live CT navigation. The procedure and discussion of this technique is described in detail. Results: With minimal radiation exposure to the patient, CT navigation for this complex talocalcaneal coalition was both helpful and potentially timesaving by allowing immediate localization and guided resection of the coalition...

RATIONALE: The calcaneal fracture without broken lateral wall is rare and the open anatomic reduction and internal fixation (ORIF) is necessary when the subtalar joint articular surface is broken and collapsed. PATIENT CONCERNS: A 45-year-old male was admitted to our department with complaints of heel pain and swelling after falling down from 1-m-high stone. He was unable to bear weight on his right foot. DIAGNOSES: Imaging studies confirmed that it was a sanders type IIIAB calcaneal fracture without broken lateral wall and the middle part of the posterior calcaneal articular facet collapsed...

AIMS: The pathogenesis of intraneural ganglion cysts is controversial. Recent reports in the literature described medial plantar intraneural ganglion cysts (mIGC) with articular branches to subtalar joints. The aim of the current study was to provide further support for the principles underlying the articular theory, and to explain the successes and failures of treatment of mICGs. PATIENTS AND METHODS: Between 2006 and 2017, five patients with five mICGs were retrospectively reviewed...

PURPOSE: To compare fixed- or variable-angle locking screws in calcaneal fracture plates using a sawbones biomechanical model. METHODS: Intra-articular calcaneal fractures were created in synthetic bones. Reduction and stabilization was performed with three different plates. In Group A, a fixed-angle locking plate was used with screws fastened perpendicularly to the plate (3.5 LCP, DePuySynthes). In Groups B and C (2.7 VA-LCP, DePuySynthes and 3.5 Aptus, Medartis, respectively), fracture fixation was performed using variable-angle locking plates...

BACKGROUND: Physical activity during childhood can be beneficial in the long term. However, this practice can influence the child's physiological development. The aim of this study was to determine whether the practice of soccer, in moderation, could be a risk factor for the inadequate development of the lower limb. METHODS: The study group was composed of 115 children, of whom 59 (mean age 8.03±0.89years) practised soccer 3 times a week and had a positive Physical Activity Questionnaire for Adolescents (PAQ-A) score, while a further 56 (mean age 7...

The triceps surae primarily acts as plantarflexor of the ankle joint. However, the group also causes inversion and eversion at the subtalar joint. Despite this, the Achilles tendon moment arm is generally measured without considering the potential influence of inversion/eversion of the foot during plantarflexion. This study investigated the effect of foot inversion and eversion on the plantarflexion Achilles tendon moment arm. Achilles tendon moment arms were determined using the centre-of-rotation method in magnetic resonance images of the left ankle of 11 participants...

BACKGROUND: Although it has been proposed that in mid-stage ankle osteoarthritis, the subtalar joint can compensate for deformities above the ankle joint, the evidence is weak. We thus investigated subtalar joint alignment in different stages of ankle osteoarthritis using weightbearing computed tomography (CT) scans. METHODS: The subtalar joint of 88 patients with osteoarthritis of the ankle joint and a control group of 27 healthy volunteers were assessed. Subgroups were performed according to the ankle deformity (varus and valgus) and stage of ankle joint osteoarthritis...

BACKGROUND: Subtalar arthrodesis through an open approach carries significant risk of complications. An arthroscopic approach aims to minimise damage to the soft tissue envelope to improve recovery, union and complication rates. A two portal approach through the sinus tarsi was used. METHODS: A retrospective review of all patients undergoing isolated arthroscopic arthrodesis was performed. RESULTS: Seventy-seven procedures were performed. Successful arthrodesis was achieved in 75 (97...

Fractures of the talus are challenging to manage, with historically poor outcomes and a high rate of complications. The rare nature of this injury limits the number of studies available to guide treatment. Fortunately, a number of advancements have been made in the last decade. There is increased recognition regarding the importance of anatomic reconstruction of the osseous injury. Advanced imaging is used to assess the subtalar joint, where even slight displacement may predispose to arthritis. Increasing use of dual anteromedial and anterolateral approaches, along with plate fixation, has improved our ability to accurately restore the anatomy of the talus...

BACKGROUND: Several anatomical studies have shown that the articular facets of the calcaneus can present with different anatomy. This study assessed the 3D anatomy of lateral calcaneal lengthening (LCL) osteotomy in relation to the anterior and middle facet of the calcaneus in a group of skeletally immature patients treated for symptomatic flatfoot deformity. METHODS: During the study period, 14 consecutive patients (10 males, 4 females) presenting symptomatic flatfoot (20 feet) with different aetiologies underwent LCL osteotomy and CT scan with 3D reconstruction of the operated feet...

BACKGROUND: The treatment of malignant tumours of the distal tibia is a challenging surgical problem due to the scarce soft tissue coverage and the instability of the ankle joint that often occurs after resection. However, there is no consensus on the ideal treatment for malignant tumours of the distal tibia. METHODS: We report a new reconstruction for five patients with high-grade osteosarcoma of distal tibia, using dual ipsilateral vascularized autogenous fibular graft in a trapezoid-shaped array and external fixator, with ankle arthrodesis and preserving subtalar joints...

INTRODUCTION: One of the reasons for revision of total ankle replacement (TAR) implants is loosening due to subchondral cysts. Reconstruction and fusion of the ankle is often the first choice for revision procedures due to the large bone defects, which are typically filled with autograft and/or allograft. Filling the defect with a trabecular metal tantalum implant is a potential alternative given the biomechanical properties of this component. HYPOTHESIS: Using tantalum as a spacer provides primary stability and contributes to fusion of the ankle joint after removal of failed TAR implants...

PURPOSE: The purpose of our study was to determine the results of arthroscopic ankle arthrodesis (AAA) and how the procedure affects adjoining joints and functional scores. METHODS: Between 1993 and 2013, 116 patients (120 ankles) underwent AAA. Nineteen ankles were lost to follow-up due to death, insufficient radiographic studies, or inability to contact, resulting in 97 patients (101 ankles). Mean age at surgery was 61.1 years (range, 35.8-79.6 years); mean follow-up was 86 months (range, 24-247 months)...

The effectiveness of subtalar arthrodesis has been well documented in treating degenerative subtalar joint disease. The arthroscopic subtalar approach for arthrodesis has also been proved to give excellent results in terms of bone fusion rates and reduction of wound-related pain and complications. To date, the main concerns about arthroscopy have regarded incision-related neurologic complications such as lesions of the tibial, fibular, and sural nerves. In this context, we present a 2-portal lateral (anterior and middle) approach to arthroscopic subtalar arthrodesis, recently documented in the literature, that provides similar excellent access to the joint with a lower risk of nerve damage...

PURPOSE: This study aimed to assess radiological changes of the ankle joint, subtalar joint and foot following the correction of varus deformity of the knee with total knee arthroplasty (TKA). It was hypothesized that following the correction of varus deformity by TKA, compensatory reactions would occur at the subtalar joint in accordance with the extent of the correction. METHODS: For this prospective study, 375 knees of patients who underwent TKA between 2011 and 2012 were enrolled...
