title: Different ways to treat subtrochanteric fractures with the Medoff sliding plate.
abstract: Thirty-two consecutive subtrochanteric fractures in 32 patients were stabilized using the Medoff sliding plate and were followed up prospectively for 1 year. Two patients died during the first postoperative year. Twenty-nine of the remaining 30 (97%) fractures united by 1-year followup. Two types of plate dynamization schema were used: uniaxial (17 patients) and biaxial (15 patients). With uniaxial dynamization, plate sliding averaged 12 mm along the femoral shaft without medialization of the femoral shaft. With biaxial dynamization along the femoral shaft and the neck, plate sliding averaged 11 mm and screw in barrel sliding averaged 9 mm; medialization of the femoral shaft ranged from 0% to 35% of the femoral shaft diameter. Three fractures treated with uniaxial dynamization had migration of the lag screw within the femoral head; all three fractures united without additional screw migration after secondary or staged biaxial plate dynamization.
