Subtalar dislocation

INTRODUCTION: Medial swivel type of talonavicular dislocation is a very rare injury; caused by high high-velocity trauma. This injury occurs due to forceful adduction of the forefoot without inversion of the foot; causing talonavicular joint to dislocate medially while calcaneum swivels under the talus with intact talocalcaeneal interosseous ligament and calcaneocuboid joint. CASE REPORT: We report a case of 38-years-old male who had medial swivel injury to his right foot, sustaining a high- velocity road traffic accident with no other injuries...

INTRODUCTION: Fractures of the talus and its associated hindfoot dislocations are uncommon. They usually result from high-energy trauma. These fractures can lead to permanent disability. Optimal treatment relies on accurate evaluation of the injury with proper imaging to identify the fracture pattern and associated injuries and to be able to make an appropriate pre-operative plan. Avoiding soft-tissue complications, avascular necrosis, and post-traumatic arthrosis are the main goal of treatment...

Although uncommon, subtalar joint dislocations remain a frequently missed orthopaedic emergency. Detailed soft tissue and neurovascular assessment is important and these should be documented as appropriate. Failure of urgent reduction might lead to increased risk of conversion to an open injury as a result of pressure necrosis of the overlying skin, risk of talar avascular necrosis and risk of neurovascular compromise. A computed tomography scan is needed in all cases following successful closed or open reduction to identify associated occult foot and ankle fractures...

BACKGROUND: To date, only a few studies have reported postoperative changes in coronal ankle alignment after valgus knee correction through medial closing wedge distal femoral varization osteotomy (MCWDFO). This study aimed to measure the changes of MCWDFO on coronal ankle and hindfoot alignment. METHODS: We retrospectively reviewed the radiographic findings of 27 consecutive patients (34 cases) with knee valgus malalignment who underwent MCWDFO for either lateral knee joint osteoarthritis (OA) or recurrent patellar subluxation/dislocation (RPD)...

BACKGROUND: Total dislocation of the talus from all its surrounding joints (talonavicular, tibiotalar, subtalar) is one kind of serious injury of the lower extremity with rare occurrence. It is usually accompanied by fractures of the talus and its periphery, as well as severe soft tissue injury, which is difficult to reset. Complications such as skin necrosis and infection are prone to occur in the early stage, and talus necrosis are prone to occur in the late stage, all of which aggravate disease severity and increase difficulties for its treatment...

BACKGROUND: The operative treatment of high-grade talar neck fractures remains challenging, despite numerous previous reports. Our goal was to determine long-term outcomes and to establish a plan for management of postoperative complications (especially, avascular necrosis [AVN] of talar body) after high-grade talar neck fractures. We hypothesized that not every case with AVN of talar body require secondary surgical interventions. METHODS: We retrospectively reviewed the radiographic and clinical findings of 14 patients who underwent operative treatment for high-grade talar neck fractures (modified Hawkins type III and IV) between January 2000 and December 2017...

INTRODUCTION: Talar neck fractures are injuries which frequently result in adverse outcomes or impairment of functional activity. Four groups were identified according to Hawkins classification and Canale modification. We present a female patient with a fractured neck of the talus associated with talonavicular dislocation, but intact tibiotalar and subtalar joints; an injury pattern not fulfilling the criteria described in the Hawkins classification. PATIENT CONCERNS: A 46-year-old woman missed a step and fell down stairs with an immediate painful right ankle and inability to bear weight...

PURPOSE: Corrective midfoot resection arthrodesis is the standard treatment of Charcot arthropathy type Sanders 2 and 3 with severe dislocation. In order to critically evaluate the effect of surgical correction, a retrospective analysis of our patient cohort was performed. Hereby, special emphasis was set on the analysis of the pre- and post-operative equinus position of the hindfoot. METHODS: Retrospectively, all patients (n = 82) after midfoot resection arthrodesis in Charcot type Sanders 2 or 3 were included...

BACKGROUND: Complete isolated calcaneal dislocation, defined as dislocation of talocalcaneal and calcaneocuboid joints with intact talonavicular joint without significant fracture, is an exceedingly rare injury. CASE PRESENTATION: A 49-year-old man, after a motor vehicle collision, presented with a closed isolated anterolateral dislocation of the calcaneus associated with fracture of the sustentaculum tali, cuboid, lateral process of the talus, and avulsion fracture of superior peroneal retinaculum...

A 16-year-old boy presented with 6 days of left iliac fossa pain. He had a medical history of right subtalar dislocation and appendicitis requiring laparotomy 3 years earlier, complicated by wound dehiscence. His family history was significant for his brother's sudden death 3 weeks prior after a 12-month illness with intermittent epigastric pain, weight loss, and hemoptysis. Travel history was significant for travel to the Philippines 3 years prior, in which he spent time in the hospital for appendicitis.

BACKGROUND: Subtalar joint dislocation (1% of all dislocations) is the permanent loss of articular relationships in the talonavicular and talocalcaneal joints, without other involvement of the foot. Dislocation can occur medially (85%), laterally (15%), posteriorly (2.5%) and anteriorly (1%). Reduction can be performed by closed or open technique; lateral dislocations often require open reduction because of inclusion of soft tissues or bone fragments. Lateral dislocations are frequently complicated by bone exposure, risk of infection and associated soft tissues injuries...

Introduction: Subtalar dislocations are rare injuries, representing around 1% of all dislocations. Defined as talonavicular and talocalcaneal separation, occurs in medial, lateral, anterior, or posterior direction. They are more common in young men, usually as a result of high energy trauma and are associated with posttraumatic arthritis, especially when accompanied with peritalar fracture (a cuboid fracture in this case), so prompt recognition is necessary in order all these complications to be avoided...

A rare case of serious non-fatal pedestrian-motor vehicle accident in the constructions sector is described, leading to severe orthopedic trauma and disability. A 49-year-old male worker was admitted to the orthopedic department due to reported occupational injury. The accident occurred at the workplace during the construction of a cycling road, where the victim as pedestrian was referred to be crashed by a motor vehicle at his left lower extremity. He consequently fell on the ground and the vehicle drifted his whole limb with its caterpillar...

Subtalar dislocations are uncommon injuries that involve disruption of the talocalcaneal and talonavicular joints. Whereas medial subtalar dislocations are usually caused by low-energy mechanisms and are reducible by closed means, lateral subtalar dislocations occur due to high-energy trauma, have associated foot injuries, and may require open reduction. Good outcomes can be expected for low-energy medial dislocations, whereas high-energy dislocations have guarded outcomes. Hindfoot deformity and chronic instability can result from nonanatomic reduction and inadequate stabilization...

The aim of this study was to characterize ankle stability of total talar prosthesis (TTP) and to determine the effect of implant sizes on stability as well as the resistance to TTP dislocation. Twelve below-knee cadaveric specimens were divided into two groups. Group 1 received a size matched implant and Group 2 received downsized implant by 5%. The stability assessment under fluoroscopy was performed for each cadaver in its native state. Following TTP insertion process, each then underwent evaluation of the TTP ankle stability...

INTRODUCTION AND IMPORTANCE: Combined fracture of the lateral malleolus and cuboid due to a lateral subtalar dislocation is an uncommon injury. Literature is scarce on this trauma association. To the best of our knowledge, this represents a new lesion pattern. Hereby we describe its mechanism, management and outcomes. CASE PRESENTATION: We report a case of a 58-year-old woman, who fell from the stairs and presented with pain and an acute deformity of the left foot and ankle...

Talar dislocations are rare injuries of the foot and ankle and require quick and decisive diagnostic and therapeutic decisions. Evidence concerning the treatment and outcome of these injuries is sparse. The aim of this study was to analyze all talar dislocations of the last ten years treated in a large German level I trauma center in an effort to add to the experience on these injuries. METHODS: All patients with a talar dislocation injury were retrospectively included. Medical reports, x-ray and computertomography scans were analyzed for the sex, age, trauma mechanism, and injury classifications as well as for the clinical outcome as measured by the Foot Function Index (FFI)...

Treatment of calcaneal fractures has to be tailored to the individual pathoanatomy. If operative treatment is chosen, anatomic reconstruction of the calcaneal shape and joint surfaces is mandatory. For most of the displaced, intraarticular fractures, this can be achieved by less invasive reduction and fixation via a sinus tarsi approach, which may be extended along the "lateral utility" line for calcaneocuboid joint involvement or calcaneal fracture-dislocations. Purely percutaneous fixation is the treatment of choice for displaced extraarticular fractures and simple intraarticular fractures with adequate control of joint reduction...
