Abstract:
The two—flange compression screw is a new instrument developed by us. This nail consists of two parts, the two—flange plate part and the compression screw part. We used it to treat 67 cases of femoral neck fracture, aged 39～79 years in 1988 to 1992. In the 67 cases there were 12 cases with stage Ⅰ type fracture, 14 with stage Ⅱ type fracture, 24 with stage Ⅲ type fracture and 17 with stage Ⅳ type fracture. We followed—up 42 cases for 8 months to 3 years, with result of good unjon in 38 cases (90%), avascular necrosis of the femoral head in 2 (5% ) and non—union in (5%). The biomechanical research demonstrated that the two—flange compression screw had the function of resisting rotation and section compression.
