| Objective:To discuss the importance of the entering point of Dynamic Compression Screw (DCS) to the treatment of reverse peritrochanteric and condyle femoral fracture and the solidification of internal fixation through researches on anatomy and mechanics of peritrochanteric and condyle femoral.Method:Treat 63 cases of the reverse peritrochanteric fracture and 68 cases of condyle femoral fracture with the DCS surgery. The surgery applies indirect replacement or incisive replacement under fluoroscopy and internal fixation of DCS. After the surgery,take conventional x-rays in obverse position and oblique position of peritrochanteric and condyle femoral. Judge the healing situation from the entering point and the healing state.Result:This group consists of 63 cases of reverse peritrochanteric fracture and 68 cases of condyle femoral fracture. Take a 8-24 months' follow-up visit.The average is 16 months.4-6 weeks after the peritrochanteric surgery,the patients can move with crutches. After 16～18 weeks they can move without crutches and bear a complete burden. The average healing time is 20 weeks.2-3 days after the condyle femoral surgery, the patients can move with crutches, after 8 weeks they are allowed to burden partly.12～14 weeks after the surgery, they can bear complete burden gradually.The average healing time is 15 weeks.10 cases failed dealed with replacement of peritrochanteric fracture and 6 cases failed dealed with replacement of condyle femoral fracture.Conclusion:Judging the fracture type and shifting direction before the surgery, and deciding the correct entering point according to the anatomical relation over the surgery is the basic guarantee for the healing rate of applying DCS to enhance the peritrochanteric and econdyle fmoral fracture. |
