Chopart fracture

Radiography is the appropriate initial imaging modality to assess for midfoot and forefoot pathology before turning to advanced imaging techniques. While most lesions of the mid- and forefoot can be diagnosed clinically, the exact nature and severity of the pathology is often unclear. This review addresses the use of the ultrasound, as well as the added value of magnetic resonance imaging, in diagnosing conditions of the midfoot and forefoot. Ultrasound allows a dynamic assessment as well as enabling imaging-guided interventions for diagnostic and therapeutic purposes...

INTRODUCTION AND OBJECTIVES: Subtalar dislocations are a rare entity (<1%) in traumatic foot injuries. There is a loss of anatomical relationship between the talus, calcaneus and scaphoid. There are only small-published series. MATERIAL AND METHODS: We present a series of patients (N=13) with subtalar dislocations in which a descriptive analysis of the main epidemiological, clinical and radiological variables was carried out, from which an urgent treatment algorithm is proposed...

INTRODUCTION: Chopart injuries can be allocated into 4 broad groups, ligamentous injury with or without dislocation and fracture with or without dislocation, which must occur at the talonavicular joint (TNJ) and/or calcaneocuboid joint (CCJ). Chopart dislocations are comprised of pure-dislocations and fracture-dislocations. We aim to review the literature, to enable evidence-based recommendations. METHODS: A literature search was conducted to identify relevant articles from the electronic databases, PubMed, Medline and Scopus...

PURPOSE: Trimalleolar ankle fractures (TAFs) are common traumatic injuries. Studies have described postoperative clinical outcomes in relation to fracture morphology, but less is known about foot biomechanics, especially in patients treated for TAFs. The aim of this study was to analyze segmental foot mobility and joint coupling during the gait of patients after TAF treatment. METHODS: Fifteen patients, surgically treated for TAFs, were recruited. The affected side was compared to their non-affected side, as well as to a healthy control subject...

INTRODUCTION: Fractures of the anterior process of the calcaneus (APC) are easily overlooked in clinical practice. Most patients have good to excellent clinical outcome after conservative treatment, while some patients may have persisting symptoms and unfavorable functional outcomes. The aim of this study was to identify the risk factors associated with unfavorable functional outcome after conservative treatment in APC fractures. METHODS: All patients presenting with APC fractures and receiving conservative treatment from April 2019 to April 2020 were retrospectively assessed...

BACKGROUND: Fractures of the anterior process of the calcaneus are often missed, and their treatments and results receive little attention in the current literature. The aim of this study was to specify treatment algorithms through a modification of the Degan classification. METHODS: Between 2009 and 2019, patients with APC fractures were retrospectively analyzed. The Degan classification was used and modified. Type III fractures were further divided into subgroups A (not displaced) and B (displaced)...

Fracture-dislocations of the midfoot are relatively rare injuries. We present a case of a 20-year-old man presenting with navicular-cuneiform and calcaneal-cuboid fracture-dislocation of his right foot due to a crush injury during work. The patient's injury was treated by open reduction internal fixation.

OBJECTIVES: To investigate injury patterns and long-term outcomes of mid-tarsal (Chopart) injuries in a sizeable number of patients. DESIGN: Prospective study. SETTING: Level-1 Trauma Center. PATIENTS: One-hundred and twenty-two patients (average age 37.6 years) with 128 Chopart injuries over a 15-year period, 27% of which were polytraumatized. In 47% more than one of the 4 bones of the mid-tarsal joint was fractured...

BACKGROUND: Trimalleolar fractures osteosynthesis is associated with a suboptimal outcome. It is hypothesized that patients with trimalleolar fractures face different ankle joint kinetics at mid- and long-term causing compensations at the distal foot joints. RESEARCH QUESTION: Do patients with a history of a trimalleolar fracture demonstrate different foot joint mechanics and energetics (1) between their affected side and their matched controls? (2) between their unaffected side and their matched controls? (3) between their affected side and their unaffected side? METHODS: Fifteen patients who sustained a trimalleolar fracture and underwent osteosynthesis for both the lateral, medial and posterior malleolus were compared to a asymptomatic control group which was matched for sex, age and walking speed...

BACKGROUND: This study aims to analyze the ligaments of the dorso-lateral calcaneo-cuboid joint and to assess the biomechanical relevance of the bifurcate ligament. METHODS: 16 specimens were analyzed for their ligamentous anatomy of the dorso-lateral calcaneo-cuboid joint and side-alternating assigned to two groups with varying ligamentous dissection order. The Chopart joint was stressed in plantar, medial, and lateral direction measuring the displacement by an 3D motion tracker for every dissection step...

The tarsal navicular is an essential component of the Chopart joint and crucial for most of hindfoot motion. Most fractures are low-energy dorsal avulsions that may be treated nonoperatively. Displaced comminuted fractures require open reduction and internal fixation, sometimes with external fixation, bridge plating, and bone grafting. Diagnosis of stress fractures is commonly delayed. Conservative treatment is associated with good results, but surgery allows for quicker return-to-play in athletes. Nonunion in acute and stress fractures needs open debridement, grafting, and stable fixation...

Ankle sprains are frequently encountered. They result most of the time in lesions of the lateral ligament complex. Nevertheless, in the context of an ankle sprains, more severe injuries including fracture of the lateral process of the talus, fracture of the base of the 5th metatarsal, tear of the medial ligament complex, lesion of the syndesmosis, sprain of the Chopart joint, and peroneal tendons luxation are potentially overlooked and, if treated inadequately, may be associated with poor functional outcome...

A rare case of Dorsal Chopart's fracture dislocation after a fall from height is presented. It combines the features of pure dorsal Chopart's dislocation and the longitudinal swivel variant described by Main and Jowett presenting as dorsomedial fracture dislocation of the medial three fourths of the navicular, crushing the lateral one fourth. The possible mechanism of injury has been described. It has been successfully treated with closed reduction and percutaneous k-wire fixation. At two-year follow-up the patient was asymptomatic, back to his moderately active work...

BACKGROUND: Common etiologies for post-traumatic ankle osteoarthritis are ankle fractures and chronic ankle instability. As the nature of trauma is different for these two etiologies, it might be expected that the two subtypes of post-traumatic ankle osteoarthritis would display different foot mechanics during gait. RESEARCH QUESTION: The objective of this exploratory cross-sectional study was to compare the foot kinematics and kinetics of patients suffering from post-fracture ankle osteoarthritis with those of patients suffering from post-sprain ankle osteoarthritis...

BACKGROUND: Pirogoff amputation is a calcaneal amputation invented by Nicolás Pirogoff that involves partial preservation of the calcaneus. CASE: A 59-year-old woman was diagnosed with left Lisfranc and Chopart joint fracture-dislocation 9 months after a fall. The patient underwent debridement together with Pirogoff amputation and surgery to place an Ilizarov external fixator. Five months later, the patient was transferred to a rehabilitation hospital. Because of inadequate bone fusion, for 3 months after the amputation the patient underwent gait training with a patellar tendon weight-bearing orthosis to avoid loading the amputated side...

BACKGROUND: Talar head fractures account for 2.6% to 10% of all talar fractures and are often associated with concomitant musculoskeletal injuries. The current literature only describes a total of 14 patients with talar head fractures and, with that, guidelines for management are lacking. The aim of the current study was to evaluate the management and long-term outcome of patients who have hindfoot trauma with concomitant talar head fractures. METHODS: This study includes a retrospective cohort of patients with talar head fractures...

We report a unique case of the total loss of the intermediate cuneiform by posttraumatic avascular necrosis resulting from a left foot open fracture and dislocation of the navicular bone and medial and intermediate cuneiforms at the Chopart and Lisfranc joints in a 64-year-old woman. The injury was managed with open reduction and internal fixation with Kirschner wires and cannulated screws. During postoperative follow-up, we observed avascular necrosis of the intermediate cuneiform and the total loss of the bone...

OBJECTIVE OF SURGERY: Joint-spanning transfixation of the ankle joint aims at mostly temporary retention of the reduction, i.e. restoring length and axial alignment and stabilization of the ankle mortise in highly unstable fractures around the ankle and under critical soft tissue conditions. In selected cases, external fixation serves as an additional stabilization also following completed internal fixation or the fracture can be treated in the external fixator. The goal of surgery is to allow quick soft tissue recovery, prevention of redislocation and stabilization of the ankle and adjacent structures...
