股骨转子间骨折四种内固定方法的临床比较（Clinical comparison of four internal fixation methods for intertrochanteric fracture） Clinical comparison of four internal fixation methods for intertrochanteric fracture Update Date: 2011-03-01, Qiu Xueli, Zhong Zhigang, Lin Bendan, Cai Zhiying Our department has used four kinds of internal fixation methods to treat intertrochanteric fracture since 1993~1996. 33 cases will be followed up as follows. clinical data 1. general data: this group is male 26, female 7, age 5~88 years old, average 54 years old. Fractures were classified according to Boyd and Criffin (1): type 6, type II, type 2, type 13, type 12, group 8, and fracture line spread to the upper femur or fracture of middle and upper femur. 2. operation methods: Patients with contralateral decubitus, femoral upper lateral incision, when necessary to extend into the Waston-Jone incision, revealed the fracture and femoral neck fracture of the base block shift significantly, especially in the area of the lesser trochanter and medial posterior medial fracture block to anatomical reduction, with the continuous structure of medial cortical bone the recovery of the medial and posterior. The ordinary compression steel plate is formed according to the shape of the big side rotor of the reinforcing side, and the first screw hole of the steel plate is expanded so that the screw thread can be screwed only by compression. After the reduction of the fracture, the guide needle is inserted into the guide needle outside the big rotor 1.5 to 2cm. The direction of the guide needle is the same as that of the right side of the neck and the anteversion angle. The guide pin is inserted into the compression nail, and this group has 12 cases. After applying the goose head nail, the guide pin was correctly inserted, then the compression nail was screwed, and the side plate was fitted. There were 10 cases in this group. The sliding compression goose head also enters the guide needle first, uses the joint drill to ext
