BACKGROUND: In patients with painful ankle arthrodesis, the surgical treatment is challenging, and may include takedown of ankle arthrodesis and conversion to a total ankle replacement (TAR). This procedure is technically demanding given the altered anatomy after arthrodesis. Few studies have evaluated TAR in the setting of prior arthrodesis. QUESTIONS/PURPOSES: (1) What intraoperative and perioperative complications were observed in patients who underwent conversion of an ankle arthrodesis to a TAR? (2) Was durable fixation achieved at short term, and what was the alignment of the components? (3) What subsequent surgical procedures were performed, including revisions? (4) What improvements were observed in pain, tibiotalar range of motion (ROM), and quality of life? METHODS: Between January 2007 and December 2014, 18 patients with a painful ankle arthrodesis underwent conversion to TAR at our tertiary referral center...

BACKGROUND: Pantalar dislocations without associated talar fracture are rare and have high risks of complications, including infection, osteonecrosis, and posttraumatic osteoarthrosis. Limited information on later function exists. This study evaluated complications and outcomes following pantalar dislocation without talar fracture. METHODS: Nineteen patients were identified with open (n = 14) or closed (n = 5) pantalar dislocations without talar fracture. Ten male and 9 female patients with a mean age of 39...

Anterior arthroscopic tibiotalar arthrodesis has been well codified. A posterior approach with the patient in prone position is indicated when the anterior approach is precluded by soft tissue issues or for a 1-step procedure associated with posterior subtalar fusion. In an anatomic study, we assessed the feasibility of posterior arthroscopic tibiotalar fusion and sought to determine the arthroscopy entry points, mortise cartilage freshening quality, and risk of osseous, tendinous, vascular, and neural complications...

Extruded talus is a rare serious result from a high-energy injury to a supinated and plantar flexed foot. Treatment remains controversial with a lack of congruent evidence for talar reimplantation. A 34-year-old woman was involved in a road traffic accident at 40 mph. Imaging revealed a left talus extruded anterolaterally with a talar neck fracture. Additional injuries included right acetabular fracture, transverse process fractures and rib fractures, which were treated conservatively. The talus was reimplanted and the talar neck fixed with a cortical screw...

BACKGROUND: Isolated type B ankle fractures with no injury to the medial side are the most common type of ankle fracture. OBJECTIVE: This study aimed to determine if surgery is superior to non-surgical management for the treatment of these fractures. METHODS: A pragmatic, multicentre, single-blinded, combined randomised controlled trial and observational study. Setting Participants between 18 and 65 years with a type B ankle fracture and minimal talar shift were recruited from 22 hospitals in Australia and New Zealand...

PURPOSE: The impact of isolated malleolar fractures on the intra-articular load distribution within the ankle joint has been studied in several biomechanical cadaver studies during the last decades. Recently, computed tomography osteoabsorptiometry (CT-OAM) has been proposed as a valuable tool to assess intra-articular joint load distribution in vivo. The purpose of this retrospective matched pair analysis was to apply CT-OAM to evaluate in vivo changes of talar load distribution after lateral malleolar fractures in patients treated with open anatomic reduction and internal fixation (ORIF) compared to patients treated non-operatively...

OBJECTIVE: To investigate the characteristics and the results of realignment surgery for the treatment of malunited ankle fracture. METHODS: Thirty-three patients with malunited fractures of the ankle who underwent reconstructive surgery at our hospital from January 2010 to January 2014 were reviewed. The tibial anterior surface angle (TAS), the tibiotalar tilt angle (TTA), the malleolar angle (MA), and the tibial lateral surface angle (TLS) were measured. Clinical assessment was performed with use of the American Orthopaedic Foot and Ankle Society (AOFAS) scale and visual analogue scale (VAS) scores, and the osteoarthritis stage was determined radiographically with the modified Takakura classification system...

BACKGROUND: Mobile-bearing total ankle replacement (TAR) enables motion at the tibial implant-polyethylene insert interface. This motion could lead to coronal translation of the talus relative to the tibia and may affect radiographic outcome. We aimed to assess the translation of the talus before and after mobile-bearing TAR to determine whether translation of the talus after TAR is associated with coronal plane alignment of the lower limb and hindfoot as well as to investigate the complications associated with talar translation...

Peripheral talus fractures include injuries to the lateral process, posteromedial talar body, and talar head. These injuries are rare and are often missed. Nonunion with conservative treatment is high and excision can lead to joint instability, rapid arthrosis, and earlier need for arthrodesis. Open reduction internal fixation of most peripheral talus fractures is critical to achieving a good outcome. Open reduction leads to more rapid union and ability to mobilize the ankle and subtalar joints, quicker revascularization of the talus, and lower rates of arthrosis...

Osteochondral lesions of the talus (OLT) occur in up to 70% of acute ankle sprains and fractures. OLT have become increasingly recognized with the advancements in cartilage-sensitive diagnostic imaging modalities. Although OLT may be treated nonoperatively, a number of surgical techniques have been described for patients whom surgery is indicated. Traditionally, treatment of symptomatic OLT have included either reparative procedures, such as bone marrow stimulation (BMS), or replacement procedures, such as autologous osteochondral transplantation (AOT)...

INTRODUCTION: Non-or partial weight bearing is frequently the standard treatment after peri-articular lower extremity fractures. Displaced talar neck fractures are severe injuries compromising vascularity of the corpus and consequently are at risk for non-union and avascular necrosis, the main reason to restrict weight bearing for up to three months according to most literature.

We report the unusual case of a 16-year-old young man who sustained a rare association of a Hawkins' type-II talar neck fracture with a complete medial subtalar dislocation (Hawkins type-IIB) that occurred as an isolated injury after indirect trauma during a soccer game. Following closed reduction of the subtalar dislocation, standard radiographs and computed tomography (CT) demonstrated a comminuted fracture of the talus involving the base of the talar neck. Open reduction was performed and the fracture was stabilized by ORIF...

Introduction Talar dislocation fractures of type IV (Marti and Weber) are extremely rare injuries with special challenges to the surgeon and poor results. Due to their low incidence and the sparse literature, it is unclear what is the optimal treatment and how complications can be minimised. Material and Methods A literature research was carried out using the online medical database "PubMed". The findings of the literature were then applied to a clinical case of type IV talar dislocation fracture (Marti and Weber)...

The talus is the second most common fractured tarsal bone. While their incidence may be low, talus fractures are severe injuries that can lead to long-term disability and pain. Displaced talar body fractures are typically treated through an open approach with the aim of obtaining anatomic reduction and stable fixation. There are several case reports in the literature demonstrating successful management of talus fractures arthroscopically. An arthroscopic approach minimizes soft tissue trauma, which can help decrease postoperative wound complications and infections...

PURPOSE OF THE STUDY Peripheral fractures of the talus (lateral talar process and posterior talar process) are rare injuries, easy to miss on examination due to their location and clinical manifestation. They account for 0.3% to 1.0% of all fractures of the talus. An incorrect or late treatment of talar process fractures can result in permanent pain, impingement syndrome, healing in malposition, pseudoarthrosis development and also, due to joint instability, in a potential development of severe subtalar arthritis...

Fractures of talus are relatively uncommon injuries with majority of them involving the neck region. Talar body fracture in sagittal plane in combination with medial malleolus fracture is very rare with few cases being reported in the literature earlier. We report such an unusual combination in an adolescent, which was treated with open reduction and internal fixation with screws for both talus and medial malleolus. This was followed by physiotherapy and non-weight bearing till the fracture united.

Isolated posteromedial ankle dislocation is a rare condition thanks to the highly congruent anatomical configuration of the ankle mortise, in which the medial and lateral malleoli greatly reduce the rotational movement of the talus, and the strength of the ligaments higher than the malleoli affords protection against fractures. However, other factors, like medial malleolus hypoplasia, laxity of the ligaments, peroneal muscle weakness and previous ankle sprains, could predispose to pure dislocation. In the absence of such factors, only a complex high-energy trauma, with a rotational component, can lead to this event...
