From 1980 to 1991, 14 patients with pure ankle dislocation unassociate
d with fracture were identified. All patients were young adults (18-41
years of age) with a male preponderance (11 of 14). The cause of inju
ry in nine of the 14 cases was a motor vehicle accident and in the rem
ainder, sporting events or fall from a height. Thirteen of the 14 inju
ries were open, and 12 patients underwent lateral ligamentous repair.
Twelve of the 14 patients were available for follow-up, which ranged f
rom 15 to 122 months. Two patients had poor results; the remainder (10
of 12) had good and excellent results. Interestingly, no patient had
signs or symptoms of instability. One patient required immediate below
-the-knee amputation for open dislocation associated with avulsion of
soft tissue and neurovascular structures.
