We treated 13 cases of subtrochanteric fracture at Kitakyushu city Yahata hospital from November 1988 to April 1991. Subjects comprised 10 males and 3 females with an average age of 42 years (range: 16-81). Fractures were classified into Type II A (3 cases), Type II B (2 cases), Type II C (1 case), Type III A (2 cases), Type III B (2 cases), Type IV (2 cases), Type V (1 case) as defined by Seinsheimer. One case treated with an AO plate did not achieve union, due to the weakness of the AO plate for subtrochanteric fracture. Two cases treated with DHS deveroped medical displasement because their Lag screws were inserted into fracture lines. But 9 cases were treated with DHS and all achieved primary healing.
