Displaced femoral neck fractures treated with the Gouffon pin

One hundred fractures of the neck of the femur, Garden stage III or IV, were treated with Gouffon pins during a three year period. Seventy-nine were followed from 24 to 52 months. Union occurred in 59 fractures. Eighteen fractures did not unite and 2 became redisplaced within the first week. Avascular necrosis was noted on radiographs in 14 of the 59 united fractures. A higher pin migration rate was found in Garden stage IV fractures, and in the failures.
