Chopart complex injuries (CCIs) are thought to be uncommon; however, recent literature states the rate of misdiagnosis to be between 20 and 41%. Chopart complex injuries are not ankle injuries, with which they are initially confused due to a similar mechanism of trauma in many cases. Injury to the Chopart complex commonly affects multiple structures. The key to optimal treatment is a high index of clinical suspicion combined with timely accurate imaging studies. Careful diagnostic workup with high-quality radiographs of the foot in neutral position should be obtained...

OBJECTIVE: Lisfranc joint injury is a rare injury and can be easily missed at the initial treatment. Once ignored, late reduction is very difficult and requires extensive dissection. Surgical outcome is not as good as in the case of an early reduction. The aim of this cohort study was to analyze the midterm clinical and radiographic outcomes of staged reduction and fixation in a consecutive series of patients with old Lisfranc injuries. METHODS: Fifteen patients (16 feet) with missed Lisfranc injuries were treated with staged reduction...

Chopart joint injuries have a profound effect on global foot function. Surgical treatment aims at joint reconstruction and axial alignment with restoration of the normal relationship of the lateral and medial foot columns. Internal fixation is tailored to the individual fracture pattern and achieved with resorbable pins, Kirschner wires, screws, and/or anatomically shaped minifragment plates. If instability persists, temporary joint transfixation may be achieved with Kirschner wires or bridge plating. Primary fusion sacrifices essential joints and should be reserved for severe initial cartilage damage...

Charcot fracture pattern (FP) and Charcot dislocation pattern (DP) are 2 distinct collapse patterns identified in Charcot neuroarthropathy of the foot and ankle. These patterns are believed to demonstrate relative differences in central bone mineral density (BMD), which has been theoretically extrapolated to describe local BMD. To assess variation in local bone composition of FP and DP patients, 10 patients, 5 DP and 5 FP were recruited. The patient's age, body mass index (BMI), radiographs, central BMD, local BMD, sRANKL (soluble receptor activator nuclear factor kappa-beta ligand), sRAGE (soluble receptors of advanced glycated end-products), and osteocalcin were measured to determined bone metabolic status and density...

The midtarsal joint, also known as the Chopart or the transverse tarsal joint, is composed of the talonavicular and calcaneocuboid articulations.(1) Midtarsal joint dislocations are rare injuries given the strong periarticular ligamentous support.2, 3 Medial, lateral, dorsal, and rarely plantar dislocations have been reported from multiple high-energy mechanisms.4, 5 We describe the case of a 24-year-old male who sustained talonavicular and calcaneocuboid plantar dislocations associated with a middle and lateral intercuneiform dislocation, open proximal 5th metatarsal fracture, 2nd-4th metatarsal base fractures, and lateral cuneiform fracture...

BACKGROUND AND AIMS: Peripheral artery disease in dialysis cases is more prone to critical limb ischemia compared to non-dialysis cases, with a significantly high rate of major amputation of the lower limbs. Lesions are distributed on the more distal side in dialysis critical limb ischemia cases. The aim of this study was to investigate the usefulness of indocyanine green angiography to determine differences in the regional circulation in the foot between dialysis and non-dialysis patients...

INTRODUCTION: Foot and ankle injuries (FAI) are very common, with about 6000 cases per day in France. Unlike lateral ankle sprain (LAS), the diagnosis of midtarsal joint sprain (MJS, also known as Chopart's joint sprain) is not widely known. This prospective study aims to detail the epidemiology of MJS and compare it to LAS. PATIENTS AND METHOD: The study was conducted within our institution over a period of 16 months. Patients with clinical signs predictive of MJS without radiographic bone lesion underwent ultrasound assessment...

Coalitions involving three joints of the midfoot are rare. To our knowledge, this is the first report of a patient having fibrocartilaginous coalition of the calcaneonavicular joint along with partial osseous fusion of the naviculocuneiform (Chopart's joint) and medial cuneiform-first metatarsal joints. These multi-coalition pathologies are challenging to address operatively as pain can persist even after recognizing and surgically addressing each coalition in a patient.

Chopart (midtarsal) joint dislocations are relatively rare but potentially serious injuries. Their low prevalence and the possible absence of evident radiological findings cannot justify misdiagnosis because an adequate and correct treatment is required to achieve a proper clinical outcome.A midtarsal joint dislocation in a 19-year-old woman is described, in which diagnosis was performed at 8 weeks of evolution. An open reduction was performed by a double approach (medial and lateral) and a Kirschner wire joint stabilization...

The ideal treatment of displaced intra-articular calcaneal fractures is still controversially discussed. Because of the variable fracture patterns and the vulnerable soft tissue coverage an individual treatment concept is advisable. In order to minimize wound edge necrosis associated with extended lateral approaches, selected fractures may be treated percutaneously or in a less invasive manner while controlling joint reduction via a sinus tarsi approach. Fixation in these cases is achieved with screws, intramedullary locking nails or modified plates that are slid in subcutaneously...

Treatment of malunion and nonunion at the Chopart joint aims at axial realignment of the midfoot to the hindfoot and restoration of the normal relationship of the lateral and medial columns of the foot. In carefully selected patients with intact cartilage, joint-preserving osteotomies are feasible at all 4 bony components of the Chopart joint to restore near-normal function. Priority should be given to the anatomic reconstruction of the talonavicular joint because it is essential for global foot function. Patients must be counseled about the risk of progressive arthritis or osteonecrosis necessitating late fusion...

A 63-year-old man dropped a metal chunk onto his left foot during his work and suffered a crush injury of the left forefoot. He underwent Chopart's amputation followed by stump coverage with sole skin at the orthopedic department on the same day. He was referred to our department for reconstruction because of poor vascularization and subsequent necrosis of tissue at the stump. After the necrotic tissue was debrided, exposure of the talus bone was noted. An artificial dermis was then applied to the stump wound, followed by local negative pressure wound therapy...

BACKGROUND: While successful subtalar joint arthrodesis provides pain relief, resultant alterations in ankle biomechanics need to be considered, as this procedure may predispose the remaining hindfoot and tibiotalar joint to accelerated degenerative changes. However, the biomechanical consequences of isolated subtalar joint arthrodesis and additive fusions of the Chopart's joints on tibiotalar joint biomechanics remain poorly understood. QUESTIONS/PURPOSES: We asked: What is the effect of isolated subtalar fusion and sequential Chopart's joint fusions of the talonavicular and calcaneocuboid joints on tibiotalar joint (1) mechanics and (2) kinematics during loading for neutral, inverted, and everted orientations of the foot? METHODS: We evaluated the total force, contact area, and the magnitude and distribution of the contact stress on the articular surface of the talar dome, while simultaneously tracking the position of the talus relative to the tibia during loading in seven fresh-frozen cadaver feet...

The purpose of the present retrospective study was to evaluate the outcomes (ie, ulcer recurrence, major amputation, death) in diabetic patients undergoing Chopart amputation because of deep infection or gangrene extending to the midfoot. From 2009 to 2011, 83 patients, aged 71.4 ± 9.3 years, underwent a midtarsal amputation and were followed up until December 31, 2012 (mean follow-up 2.8 ± 0.8 years). Of the 83 patients, 26 were female, 61 required insulin, 47 had renal insufficiency, 19 underwent hemodialysis, 65 had hypertension, 34 had a history of cardiac disease, and 4 had a history of stroke...

BACKGROUND: Injuries to the mid-tarsal (Chopart) joint are frequently overlooked or misinterpreted and therefore, not adequately treated at initial presentation. Malunion results in a loss of essential joint function and a three-dimensional malalignment leading to considerable impairment of global foot function and a rapid development of painful posttraumatic arthritis. METHODS: If no symptomatic arthritis is present, joint displacement or non-union may be subject to secondary anatomical reconstruction and internal fixation...
