Bone Peg Fixation of the Femoral Head Fracture Associated with Posterior Dislocation of the Hip / 대한정형외과학회잡지

ABSTRACT

Seven cases of traumatic fractured femoral heads with posterior dislocation of the hip were treated at the Keimyung University Hospital between November 1973 and December 1981. All cases were followed from 6 months to 8 years. Five cases were caused by traffic accidents. The other two cases were caused by a landslide. In six cases, at first a closed reduction was performed under general anesthesia and the femoral head was reduced in the acetabulum, but in 5 of the 6 cases head fragments were not reduced. So, after one or more days, open reductions were performed on the remaining 5 cases by internal fixation with iliac bone pegs (two-four). In the remaining one case of the 6, who had a head injury and an intestinal rupture, after the closed reduction, one head fragment was reduced but not anatomically. But because of his poor general condition, conservative treatment was taken. During conservative treatment redislocation and displacement of the head fragment occurred at the 4th week after the closed reduction was done. So this case was also treated by the above method. The 7th case, who has an ipsilateral femoral neck and intertrochanteric fracture, was reduced by primary open reduction. By the classification of the Pipkins, there were 4 cases of Type I and Type II, III and IV each had I case. The post operative X-ray and follow-up study showed that two were classified as excellent, four as good and the one who had the ipsilateral femoral neck and intertrochanteric fracture (Pipkin's Type III) was classified as poor.
