BACKGROUND: The purpose of this study was to assess the radiographic progression of subtalar and talonavicular degenerative joint disease in a series of patients who had undergone TAA (total ankle arthroplasty) with minimum follow-up of 5 years. METHODS: TAA patient radiographs from a single institution were analyzed for peritalar arthritic changes by extrapolating the modified Kellgren Lawrence (KL) grades of the knee to the subtalar and talonavicular joints. Patients were included if they had a minimum of 5 years of follow-up...

BACKGROUND: The purpose of the current study was to determine sagittal plane talocrural and subtalar kinematic differences between barefoot and controlled ankle movement (CAM) boot walking. This study used fluoroscopic images to determine talar motion relative to tibia and calcaneal motion relative to talus. METHODS: Fourteen male subjects (mean age 24.1 ± 3.5 years) screened for normal gait were tested. A fluoroscopy unit was used to collect images at 200 Hz during stance...

BACKGROUND: Calcaneum is the most commonly fractured tarsal bone. The optimal treatment for displaced calcaneus fractures involving the posterior facet is surgical. The extensile lateral approach is commonly preferred because it provides sufficient exposure of the subtalar facet. However, this technique has the risk of complications such as wound necrosis and sural nerve injury. Various minimally invasive approaches, such as sinus tarsi approach, limited posterior approach, and percutaneous approach, have been introduced to reduce possible complications...

INTRODUCTION/AIM: Foot structure has been implicated as a risk factor of numerous overuse injuries, however, the mechanism linking foot structure and the development of soft-tissue overuse injuries are not well understood. The aim of this study was to identify factors that could predict foot function during walking. METHODS: A total of eleven variables (including measures of foot structure, anthropometry and spatiotemporal gait characteristics) were investigated for their predictive ability on identifying kinematic, kinetic and energetic components of the foot...

Dislocation of the fourth and fifth tarsometatarsal joints in conjunction with lateral subtalar dislocation is a rare occurrence. Little is known about the mechanism of injury, the appropriate treatment for this condition, and its ultimate prognosis. In this report, we describe this atypical presentation in a middle aged, otherwise healthy male who sustained a trivial twisting injury to the ankle when he slipped and fell on ice. Open reduction and K-wire fixation were necessary to affix the lateral tarsometatarsal and talonavicular joints...

Tibial coronal inclination is often recognized in everyday life, but the compensatory kinematic changes to maintain plantigrade of the hindfoot in response to tibial coronal inclination remain unclear. Lower legs and foot specimens obtained from seven human cadavers were loaded vertically with traction of Achilles' tendon in different tibial inclinations: 0° (neutral), 5°, and 10° medial inclination, and 5° and 10° lateral inclination. The orientations of the tibia, talus, and calcaneus were recorded under vertical load by a three-dimensional digitizing stylus...

BACKGROUND: Tibiotalocalcaneal arthrodesis is most common and effective surgical treatment for severe hindfoot pathology, but the fusion rate is often lower than the ordinary tibiotalar arthrodesis because of the more serious joint disease associated with obvious deformity and osteoporosis. Recent literature describe tibiotalocalcaneal arthrodesis with reverse PHILOS plate with good clinical outcome result, though some patients non-union, due to eccentric force of the plate may be hidden...

Flatfoot is a common condition in growing-age patients. Despite its common presentation, nowadays surgical indications and treatments are still debated. Arthroereisis is a widely used technique, and several implants designs have been proposed over time. Despite the good results shown in the literature, the main drawback of these techniques has always been the need for a second surgery for implant removal. Bioabsorbable devices have been introduced to overcome this necessity.Correct approach to the patient, indications and contraindications and available studies on bioabsorbable implants for subtalar arthroereisis in pediatric flatfoot were analyzed in this narrative review...

BACKGROUND: Fractures of the talar neck are relatively uncommon yet current interventions suffer from a high incidence of complications and poor functional outcomes. In the present study, we report a surgical treatment of Hawkins type III talar neck fracture through the approach of medial malleolar osteotomy and mini-plate for fixation and discuss the therapeutic effects after long-term follow-up. METHODS: From January 2010 to January 2015, 21 patients with 22 fractures were treated using this approach within days of sustaining the injury...

A subset of C2/C3 pilon fractures, open pilon injuries, metaphyseal bone comminution, and those involving substantial soft tissue or vascular injury may be nonreconstructable. Such injuries are at risk of progress to nonunion and failing open reduction internal fixation (ORIF). The risk of infection, malunion, and nonunion is relatively high with such injury patterns. In such cases, tibiotalar arthrodesis is performed after ORIF fails as a salvage procedure. Overall, the literature agrees that all pilon fractures will develop posttraumatic osteoarthritis, and these patients are ultimately treated with an arthrodesis or in narrow population with total ankle arthroplasty...

OBJECTIVES: Adequate management of haemophilia patients requires early detection of joint impairment in relatively asymptomatic patients. This study sought to quantify the impact of the ankle's structural impairment on muscle strength in children, adolescent and young adults with haemophilia (CAAwH). METHODS: Twenty-three CAAwH underwent bilateral magnetic resonance imaging (MRI) assessing the anatomical status of tibiotalar joint (TTJ) and subtalar joint (STJ) using the International Prophylaxis Study Group MRI scale...

Tibiotalocalcaneal arthrodesis is an effective salvage procedure in cases of combined ankle and subtalar osteoarthritis as well as severe multiplanar deformities and severe joint destruction of the hindfoot. Special mention should be made of this procedure in cases of bone loss, especially from the talus, secondary to failed previous surgeries or bone infection, often being the only way to achieve a stable and painless foot and ankle. We present a case of ankle fracture in a patient with associated morbidity and multiple complications following osteosynthesis, in which tibiotalocalcaneal arthrodesis with cemented with antibiotic coated retrograde nail has achieved a satisfactory final result...

PURPOSE: Early post-operative exercise and weight-bearing activities are found to improve the functional recovery of patients with displaced intra-articular calcaneal fractures (DIACFs). We hypothesized that early functional exercise after surgery might have a secondary reduction effect on the subtalar joint, in particular the smaller fracture fragments that were not fixed firmly. A prospective study was conducted to verify this hypothesis. METHODS: From December 2012 to September 2013, patients with unilateral DIACFs were enrolled and received a treatment consisting of percutaneous leverage and minimally invasive fixation...

Use of subject-specific axes of rotation may improve predictions generated by kinematic models, especially for joints with complex anatomy, such as the tibiotalar and subtalar joints of the ankle. The objective of this study was twofold. First, we compared the axes of rotation between generic and subject-specific ankle models for ten control subjects. Second, we quantified the accuracy of generic and subject-specific models for predicting tibiotalar and subtalar joint motion during level walking using inverse kinematics...
