talotarsal dislocation

BACKGROUND: The partial dislocation of the talus from the calcaneus and navicular bones is a primary factor leading to a prolonged overpronation during weightbearing. This study aimed to assess the possibility of returning to physical activity and long-term patient satisfaction after an extra-osseous talotarsal stabilization (EOTTS) procedure with a HyProCure sinus tarsi implant for partial talotarsal joint dislocation (TTJ). METHODS: A total of 41 adult patients (61 feet), with an average age of 46...

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...

Introduction: Flexible flat foot is one of the most common foot conditions found amongst any age group across the world. One very important reason for this condition is the incongruency or partial dislocation of one or more joints within the talo-tarsal mechanism. This flexible talo-tarsal malalignment is termed as recurrent talo-tarsal joint dislocation (RTTJD). Materials and Methods: Between 2016 and 2018, 32 patients were advised Extra osseous talo-tarsal stabilization (EOTTS) as a standalone procedure for RTTJD following detailed clinical examination including foot posture index (FPI) scoring and weight-bearing radiographic evaluation...

Isolated acute traumatic subtalar dislocations are quite rare. They correspond to talotarsal dislocation, including the talonavicular and talocalcaneal joints. The purpose of the present study was to evaluate the functional and radiologic outcomes of the treatment of acute traumatic isolated subtalar dislocations. The present retrospective study included 13 patients who had sustained isolated subtalar dislocations during a 10-year period. Of the 13 cases, 10 (76.9%) were medial dislocations and 3 (23.1%) were lateral dislocations...

The diagnosis of and preferred treatment regimens for pediatric flatfoot, a complex and ambiguous deformity, continues to be debated. Incongruence of the talotarsal joint, whether flexible or rigid, is always present in pes planovalgus. However, it is important to note that talotarsal dislocation can occur without a flatfoot. The displacement of the talus on the hindfoot bones serves as the apex of the deformity. External measures, such as conservative care, are limited in providing correction to this internal deformity...

The present multicenter, prospective study evaluated the subjective outcomes in patients after extraosseous talotarsal stabilization using the HyProCure(®) stent as a standalone procedure for the treatment of recurrent and/or partial talotarsal joint dislocation (RTTD) in a population of pediatric and adult patients. RTTD has been cited as a possible etiology for a number of foot ailments and might contribute to the development of pathologic features localized more proximally in the weightbearing musculoskeletal chain...

The purpose of this study was to determine radiographic correction achieved in adult patients treated with an extraosseous talotarsal stabilization (EOTTS) procedure. Patients diagnosed with flexible/reducible talotarsal joint dislocation (partial) underwent surgical correction with the HyProCure(®) EOTTS device. Preoperative and postoperative weightbearing radiographs taken in the anteroposterior (AP) and lateral views for a total 95 feet (in 70 patients) were analyzed to determine standardized radiographic angles, and to quantify the correction obtained after the EOTTS procedure...

Displacement of the articular facets of talus on the tarsal mechanism, or partial talotarsal dislocation, is a condition seen in children, adult, and geriatric populations. A characteristic of this pathologic condition is a prolonged period of and excessive amount of pronation (hyperpronation) on weightbearing. The ill effects of this condition may lead to a multitude of other foot pathologies and to pathologies associated with the proximal lower extremity musculoskeletal structures. A variety of conservative and operative treatment options have been used to eliminate or minimize hyperpronation...

The purpose of this retrospective study was to determine long-term functional outcomes and device tolerance achieved in adult patients who chose to undergo an extraosseous talotarsal stabilization procedure HyProCure(®) for the treatment of flexible talotarsal joint deformity. Eighty-three adult patients participated in this study. Postoperative subjective assessment of device performance was evaluated using Maryland Foot Scores, which were collected at a mean follow-up period of 51 months. The mean postoperative Maryland Foot Score was 88 out of 100; postoperatively, 52% of cases reported complete alleviation of foot pain, 69% of cases had no limitations on their foot functional abilities, and 80% of cases reported complete satisfaction with the appearance of their feet...

The navicular drop in the sagittal plane on weight-bearing is a valid indicator of foot pronation. Dislocation of the talus on the tarsal mechanism results in hyperpronation, which can lead to excessive navicular drop. The purpose of the present study was to radiographically determine the efficacy of HyProCure(®) in realigning the navicular bone in hyperpronating feet. We hypothesized that following the placement of HyProCure(®), the navicular height would increase significantly compared to its preoperative value...
