BACKGROUND: Third generation total talar prostheses (TTPs) are viable options for talar avascular necrosis (AVN) in the absence of neighboring joint pathology. The use of modern three-dimensional (3D) printing allows the production of custom implants that exactly mimic the patient's anatomy. The aim of this study is to determine the accuracy of 3D printing in reproducing a synthetic talus and, in doing so, restoring more normal anatomical relationships. We hypothesize that this mode of replication will restore and maintain normal radiographic alignment of the ankle, subtalar, and forefoot joints in the setting of talar AVN...

PURPOSE: Foot orthoses maybe used in the management of musculoskeletal disorders related to abnormal subtalar joint (STJ) pronation. However, the precise mechanical benefits of foot orthoses for preventing injuries associated with the STJ are not well understood. The aim of this study was to investigate the immediate effect of foot orthoses on the energy absorption requirements of the STJ and subsequently tibialis posterior (TP) muscle function. METHODS: Eighteen asymptomatic subjects with a pes planus foot posture were prescribed custom-made foot orthoses made from a plaster cast impression...

The use of subtalar joint neutral (STJN) in the assessment and treatment of foot-related musculoskeletal symptomology is common in daily practice and still widely taught. The main pioneer of this theory was Dr Merton L. Root, and it has been labeled with a variety of names: "the foot morphology theory," "the subtalar joint neutral theory," or simply "Rootian theory" or "Root model." The theory's core concepts still underpin a common approach to musculoskeletal assessment of the foot, as well as the consequent design of foot orthoses...

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...

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...
