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...

When insertional Achilles tendinopathy is addressed surgically via a central-Achilles splitting approach, the calcaneal osteotomy has classically been performed from distal to proximal. We describe a simple proximal to distal technique that allows optimal resection of both the calcaneal exostosis and Achilles enthesophyte, minimizes risk to the soft tissues and skin, provides a bony attachment surface parallel to the axis of the Achilles tendon, and avoids the risk of osteotomy extension into the subtalar joint...

INTRODUCTION: It has been widely postulated that structural and functional misalignments of the foot, such as flat foot, may cause mechanical deviations of the lower limb during walking. The aim of this study was to investigate the effect of foot orthoses on lower extremity joint moment asymmetry during the stance phase of walking in children with asymptomatic flexible flat feet. METHODS: Fourteen volunteer male children, clinically diagnosed with flexible flat feet, participated in this study...

PURPOSE: A too-long anterior process of the calcaneus is a common cause of pain and hind-foot instability. Our goal was to evaluate the early results of arthroscopic resection in terms of static foot disorders in children and adolescents. METHODS: We retrospectively studied 11 ft (10 patients). The inclusion criteria were treatment of TLAP by arthroscopic resection and a minimum follow-up period of six months. Surgery was indicated in cases with persistent symptomatic TLAP resistant to orthopaedic treatment...

Talus fractures with associated dislocations are rare but have high rates of complications, including avascular necrosis (AVN). Management of these injuries involves urgent surgical reduction and fixation, although there are no definitive data defining an operative time frame for preserving the blood supply and preventing complications. To determine the effect of time to surgical reduction of talus fractures and talus fracture-dislocations on rates of AVN and posttraumatic osteoarthritis (PTOA), we retrospectively reviewed talus fractures surgically managed at a level I trauma center during the 10-year period 2003 to 2013...

Hasan Bombaci
Calcaneal apophyseal fractures are usually considered sport-related injuries. Previous repetitive microtrauma has been proposed as a predisposing factor for such injuries. However, unlike previously reported cases, in our patient, the fracture resulted from acute trauma after stepping on uneven ground. Although the first treatment option for such cases is closed reduction, most cases will require surgical treatment. Furthermore, lesions accompanying this injury have not been sufficiently considered. We report the case of a 9-year-old female with a calcaneal apophyseal fracture treated by fixation of the avulsed proximal part of the apophysis using Kirschner wires and a cerclage wire...

This pictorial review focuses on basic procedures performed within the field of podiatric surgery, specifically for elective reconstruction of the midfoot and rearfoot with focus on the flatfoot deformity. Our goal is to demonstrate objective radiographic parameters that surgeons utilize to initially define the deformity, lead to procedure selection, and judge post-operative outcomes. We hope that radiologists will employ this information to improve their assessment of post-operative radiographs following reconstructive foot surgeries...

mTOR inhibitors have been associated with SWC when used in the perioperative period. Limited literature is available to guide providers in managing chronic mTOR inhibitor use in the perioperative period, especially in the pediatric setting. The primary aim of this study was to describe the prevalence of SWC with mTOR inhibitor continuation during the perioperative period for major surgeries. Heart transplant recipients ≤25 years old at the time of primary heart transplant receiving sirolimus maintenance therapy during a surgical procedure and within the study period were included...

Posterior subtalar dislocation is an exceedingly rare entity. Clinically, the appearance of the foot can simulate a complex fracture dislocation. It is important to recognize that not all posterior subtalar dislocations are true posterior dislocations. We report a true posterior subtalar dislocation in a 34-year-old female, managed promptly with closed reduction and resulting in an excellent functional outcome. A chronic dislocation or an irreducible dislocation may need open reduction.

BACKGROUND: Collapse of the medial longitudinal arch and subluxation of the subtalar joint are common occurrences in adult flatfoot deformity. Controversy exists about the role of the tibialis posterior (TP) tendon as first and/or essential lesion. Subtle changes in the foot configuration can occur under weight bearing. PURPOSE: This human cadaveric study is designed to investigate the effect that isolated actuation of the TP tendon has on the medial longitudinal arch and the hindfoot configuration under simulated weight bearing...

The purpose of this study is to investigate the compensatory correlation between knee and hindfoot in patients with rheumatoid arthritis (RA). This cross-sectional study included 218 patients (407 lower extremities). Radiographs of the hindfoot and full-length posteroanterior hip-to-calcaneus standing radiographs were evaluated. The destruction of the hindfoot was evaluated using the Larsen grading system. The coronal angular deformity of the knee and hindfoot was evaluated by the femorotibial angle (FTA) and the angle between the tibial shaft and the entire hindfoot (tibiohindfoot angle, THFA)...

The in vivo kinematic characteristics of the tarsal joints during gait stance phase were still unclear in adult-acquired foot deformity (AAFD). This study included seven healthy subjects (fourteen feet) and twelve stage II AAFD patients (fourteen feet). The 3D models of tarsal bones were reconstructed based on CT scan. Each subject took standard gait on the single fluoroscopy system. Continuous lateral fluoroscopic images were collected. The key postures during the stance phase were selected. The 2D-3D registration technique was applied to explore the spatial motions of the tarsal joints in 6 degrees of freedom (DOF)...

BACKGROUND: Hindfoot arthritis or significant deformity involving the ankle and subtalar joint (STJ) is a disabling condition with few salvage options. Many surgeons note a decreased STJ fusion rate compared with ankle union when a retrograde nail construct is used. The purpose of this study was to report the STJ fusion rate of tibiotalocalcaneal (TTC) arthrodesis with retrograde nail. METHODS: A chart and radiographic review was performed. TTC fusions performed in patients with osteoarthritis, posttraumatic arthritis, or deformity correction with retrograde nail fixation were included...
