Fifty seven consecutive trochanteric hip fracture treated with Smith-Petersen nail and Thornton plate who were treated at the Department of Orthopedic Surgery, St. Mary´s Hospital Catholic Medical College, during the period- of January 1969 to September 1975 were reviewed. This covered a period of six years and nine months. Of the fifty seven cases treated with this method, only thirty four cases were able to be analysed completely. Of these thirty four cases, in two cases the nail penetrated to the hip joint, four cases showed a loosening bolt of the S-P nail, one case involved a delayed union and three cases resulted in malunion, showing a total failure rate of 29.4%. In addition, foul cases of intertrochanteric hip fractures of children were reviewed.
1) The sex ratio was 2.1:1 (male to female). Those in their fifth decade showed the highest incidence at 26.3%, next came those in their third decade.
2) The most common cause of the trochanteric hip fractures was traffic accidents (57.9%), other cause were slipping or faring down, direct trauma and pathological fractures.
3) The ratio of left trochanteric hip fractures to right was 7 : 6.
4) In the group which received external immobilization with Buck´s extension skin traction and delayed weight bearing method, the results were better than that group to which external immobilization was not applied and early weight bearing was allowed. ´
5) The group which received the external immobilization and delayed weight bearing method showed a total failure rate of 21.8%.
6) The group to which external immobilization was not applied and early weight bearing was allowed a total failure rate of 64%.
