Fractures of the neck of the talus.

One hundred and twenty-three patients with fracture of the neck of the talus were followed up over an average of 22 months. Ffity-four fractures were undisplaced, 53 associated with subtaler dislocation, and 16 associated with dislocation of the talus in both ankle joint and subtalar joint. Of the total 123 patients, 21% (26/123) developed avascular necrosis, 31% (38/123) developed talo-crural and 47% (58/123) subtalar osteoarthrosis. Fifteen per cent (18/123) of the fractures united with considerable deformity, and four per cent (5/123) exhibited non-union of the neck. Out of 63 patients with isolated fracture of the neck of the talus, 65% (41/63) reported moderate or severe complaints, and 52% (33/63) complained of functional disability often resulting in a change to lighter work. Even among the 54 undisplaced cases there were unexpected numbers of late sequelae, such as osteoarthrosis, subjective complaints and disablement.
