BACKGROUND Ankle osteoarthritis commonly involves sagittal malalignment with anterior translation of the talus relative to the tibia. Total ankle arthroplasty has become an increasingly popular treatment for patients with symptomatic ankle osteoarthritis. However, no comprehensive study has been conducted on the outcomes of total ankle arthroplasty for osteoarthritis with preoperative sagittal ...

Total dislocation of the talus from all of its joints is a rare injury specially when the talus and malleoli are not fractured and frequently it is as a result of a high-energy trauma. It usually leads to degenerative changes in neighboring joints and frequently avascular necrosis is a predictable outcome. We present a case of total talus dislocation because of a high-energy trauma in associati...

Avascular necrosis after fracture of the talus is well recognized, but is very rare in children. We report a case of avascular necrosis of the talus simulating juvenile idiopathic arthritis. The diagnosis was confirmed by open biopsy, and non-operative treatment was performed. The patient was asymptomatic with full range of motion postoperatively for two years. We hypothesize that avascular nec...

Osteochondral lesions of the talus (OLT) are rare joint disorders. The talus is the third most common location of this disorder, following the knee and elbow joints. OLT represents 4% of all osteochondral lesions in the body. This article discusses the surgical treatment and postoperative rehabilitation of osteochondral lesions of the talus.

It has long been known that avascular necrosis of the talus may occur as a sequel to certain fractures and dislocations. Consequently the blood supply to the talus has been the subject of considerable investigation. The arterial supply to the talus has been well described in most of its aspects but the arterial distribution and the anastomoses within the bone have not been elucidated completely...

ABSTRACT Total talus dislocation is a rare injury and is commonly accompanied by associated fractures. Common worrisome sequelae are infection, avascular necrosis and post-traumatic arthritis. We report here on a patient who sustained an open total talus dislocation with an ipsilateral medial malleolus fracture. Following early debridement, reduction and a combination of internal and external f...

We present a review of the literature on classification and treatment of osteochondral defects of the talus. We report the case of an isolated Berndt and Harty grade II lesion treated with a fresh osteochondral allograft. We believe that fresh allograft osteochondral grafting of the talus is an excellent technique for symptomatic Berndt and Harty grade II or higher lesion of the talus without s...

20 In a pilot study, I observed a relationship between domestic livestock grazing and location of 21 American pika (Ochotona princeps) haypiles in the eastern Sierra Nevada and several Great 22 Basin mountain ranges. Where vegetation communities adjacent to talus bases (forefields) were 23 grazed, mean distance from talus borders to closest fresh haypiles was 30.1 m (SD = 18.9 m, n = 24 27), an...

A completely extruded talus without any remaining soft tissue attachments is extremely rare. The present report describes treatment of a 45-year-old man who sustained a completely extruded talus injury following a rock-climbing fall. Upon admission, the extruded talus was deep-frozen in our bone bank. The open ankle joint underwent massive wound debridement and irrigation for 3 days. Four days ...

Talus slopes in western North America frequently are bordered by vegetation that differs in biomass, cover, height, and species composition from vegetation located farther from talus. These areas are grazed by pikas (Ochotona princess, which nest in that talus. Foraging theory predicts that pikas will produce a gradient of grazing pressure, which could produce the observed vegetational zonation...
