Subtalar dislocation

Subtalar dislocation is characterized by simultaneous dislocation of the subtalar (talocalcaneal) and talonavicular joints, hence the name talocalcaneonavicular. These lesions can be grouped into four distinct categories: anterior and posterior, which are exceptional, lateral and medial. Medial subtalar dislocations are more frequent, are due to low-energy trauma and generally have good functional results. Anatomical reduction and stabilization of the subtalar joint and optimal management of all associated foot injuries are the key to good results...

BACKGROUND: Isolated subtalar joint dislocations without associated fractures are rare in the medical literature. They occur when the talus bone remains in place while the calcaneus and navicular bones shift out of place. These dislocations account for about 15% of talus bone injuries and 1 to 2% of all joint dislocations. They are more common in young men following inversion trauma. OBJECTIVE: This study aims to improve the understanding of diagnosis, treatment, and management of these rare injuries for better patient care...

We present a rare case of concurrent open Achilles tendon tear and pure subtalar dislocation in a 20-year-old male following a motorcycle accident, highlighting the complexity of managing such unique musculoskeletal injuries. The patient was initially admitted with an open and deformed left ankle, underwent prompt primary debridement, and received immediate medical intervention. Despite unsuccessful attempts to reduce the dislocation through external maneuvers, subsequent radiographic evaluation revealed a subtalar dislocation associated with a 90° rotation of the talus...

Lateral subtalar dislocations are rare injuries with the potential for misdiagnosis and for poor patient outcomes if missed. Prompt reduction and surgical intervention is the consensus and is key to improved patient outcomes.We present a case of a male patient in his 70s who was brought in by ambulance to the emergency department late one afternoon with a lateral subtalar dislocation associated with calcaneal and lateral malleolar fractures. He was operated on that evening, involving cannulated screw fixation of the calcaneus and buttress plating of the lateral malleolus...

Simultaneous talocalcaneal and talonavicular joint dislocation, in other words, subtalar joint dislocation, and navicular bone lateral process fracture are rare orthopedic injuries. In this case, we aimed to discuss the effectiveness and ergonomics of non-surgical follow-up with a short leg splint after reduction of talonavicular, talocalcaneal joint dislocation, and lateral process fracture of the navicular bone. A 17-year-old male patient was admitted to the emergency department with swelling and pain in his left foot after spraining his left foot while playing football...

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...

Lateral subtalar dislocations are rare and severe injuries caused by high-energy trauma, and they require urgent treatment. We reported two cases of lateral subtalar dislocation, which were treated with different methods. In case of open lateral subtalar dislocation, we used the method of distractional external fixation; the final outcome was good, without avascular necrosis of the talus. The case of closed subtalar dislocation has been treated with open reduction and K-wires fixation. The final outcome was poor, with avascular necrosis of the talus...

PURPOSE OF THE STUDY Extended lateral approach to calcaneus fractures is associated with a high risk of infection. Such risk can be reduced by using mini-invasive approaches. The sinus tarsi approach provides a good overview of the posterior joint facet of the calcaneus and can also be done as a mini-invasive procedure. The authors present their fi rst experience with osteosynthesis of joint depression calcaneal fractures using the anterolateral locking plate inserted through the sinus tarsi approach. MATERIAL AND METHODS During the period from 1 February 2020 to 31 January 2022, 18 patients were treated by the anterolateral locking plate in the authors' department (3 women, 15 men)...

BACKGROUND: Subtalar arthroereisis (STA) has gained growing acceptance as a viable approach solution for the management of pediatric flexible flatfoot. However, STA still remains controversial. The purpose of this study is to assess the effect of STA using the Talar-Fit implant for treating pediatric flexible flatfoot. Specifically, the aims of the study are as follows: first, to present the mid-term outcomes of STA using the Talar-Fit implant; second, to compare the radiographic and clinical outcomes associated with varying sizes of Talar-Fit implant; and third, to analyze the optimal position of the inserted implants...

BACKGROUND: Extruded talus (ET) injuries are rare, but high-energy open pantalar dislocations. Literature on these injuries is sparse and optimal treatment protocols are ill defined. The current study documents the clinical and radiological outcomes in cases seen at 2 centers, in an attempt to determine whether surgeons should choose primary reimplantation or primary talectomy and fusion for these injuries. METHODS: Patients with ET injuries were identified from the database of two hospitals...

A talar body fracture is typically associated with talar body dislocation, resulting in ankle and subtalar joint subluxation and/or dislocation. A talar body fracture with talar head dislocation is a very rare injury. In this report, we describe the case of a 23-year-old man who suffered a coronal shearing fracture of the talar body with talar head dislocation related to a navicular compression fracture. The patient sought orthopedic consultation 6 weeks after injury. The injury was managed with open reduction, talar head relocation, internal fixation of the talar body fracture with Kirschner wires and cancellous screws and talonavicular fusion with an iliac bone autograft...

INTRODUCTION: Subtalar dislocation is defined by a simultaneous total separation of the talocalcaneal and talonavicular joints. Lateral variety is the rarest. It is the result of a high energy trauma. It occurs following forced eversion, with the foot locked in a rut with pressure on the lateral aspect of the leg. Articular fractures of the calcaneus occur as a result of axial impact on the greater tuberosity.We report the case of a lateral subtalar dislocation associated with a calcaneal fracture...

CASE: A 74-year-old woman with rheumatoid arthritis had undergone total ankle arthroplasty (TAA) for severe ankle joint destruction at our hospital 14 years earlier. Radiographs of the ankle revealed displacement of the tibial component and subsidence of the talar component. Revision TAA was performed using a customized alumina ceramic total talar prosthesis. CONCLUSION: The 10-year outcome of revision TAA with a total talar prosthesis was satisfactory, with no postoperative complications, such as displacement of the tibial component, dislocation of alumina ceramic artificial talus, or progression of degenerative changes in the talonavicular and subtalar joints...

The demand for physical medicine and rehabilitation services has risen significantly. Immediate rehabilitation is not always readily available which may compromise patients' functional recovery. Here, we describe a rare subtalar dislocation case and how an unsupervised home-based rehabilitation program allowed functional recovery. A 49-year-old male presented to the emergency department with an injury to the right ankle which resulted from a 3-meter height fall with his foot in plantar flexion and inversion...

Subtalar joint is a complex joint in hindfoot formed by the talus superiorly and the calcaneus and navicular inferiorly. Subtalar dislocations are high-mechanism injuries, which are caused by simultaneous dislocation of both talonavicular and talocalcaneal joints, without major fracture of the talus. They are usually classified as medial (most common), lateral, anterior and posterior dislocations, based on the position of foot in relation to talus and the indirect forces that have been applied to cause this significant injury...

INTRODUCTION AND IMPORTANCE: Concomitant medial subtalar dislocation and a rotated displaced talar neck fracture may result in poor outcomes. This study aimed to explain this extremely rare injury and assess the clinical outcomes following surgical treatment. CASE PRESENTATION: A 22-year-old Iranian man referred to the emergency department with a gross deformity and pain in his right foot and ankle after a falling from 2 m. Plain radiographs showed a rotated free talar head accompanying medial subtalar dislocation...

Collapsing foot deformity (CFD) and its resulting sequelae caused by recurring talotarsal joint dislocation (RTTJD) affects pediatric and adult patients. An extraosseous talotarsal stabilization (EOTTS) procedure, a subset of subtalar arthroereisis (SA) procedures, is recommended as a minimally invasive, first in line surgical treatment option for CFD. The aim of this multicenter, retrospective study was to evaluate patient reported outcomes measures in patients who were treated for RTTJD with Type II EOTTS implants...
