Intertrochanteric Femoral Condyle Fracture Of The Anatomical Characteristics And The Dynamic Condylar Plate (dcs) Applications

Objective: To discuss the importance of the entering point ofDynamic Compression Screw (DCS) to the treatment of reverseperitrochanteric and condyle femoral fracture and the solidification ofinternal fixation through researches on anatomy and mechanics ofperitrochanteric and condyle femoral.Method: Treat 63 cases of the reverse peritrochanteric fracture and 68cases of condyle femoral fracture with the DCS surgery. The surgeryapplies indirect replacement or incisive replacement under fluoroscopyand internal fixation of DCS. After the surgery,take conventional x-raysin obverse position and oblique position of peritrochanteric andcondyle femoral. Judge the healing situation from the entering point andthe healing state.Result: This group consists of 63 cases of reverse peritrochantericfracture and 68 cases of condyle femoral fracture. Take a 8～24months' follow-up visit.The average is 16 months. 4～6 weeks afterthe peritrochanteric surgery,the patients can move with crutches. After8～12 weeks they can move without crutches and bear a complete burden.The average healing time is 20 weeks. 2～3 days after thecondyle femoral surgery, the patients can move with crutches, after 8weeks 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 peritrochantericfracture and 6 cases failed dealed with replacement of condyle femoralfracture.Conclusion: Judging the fracture type and shifting direction beforethe surgery, and deciding the correct entering point according to theanatomical relation over the surgery is the basic guarantee for the healingrate of applying DCS to enhance the peritrochanteric and econdyle fmoralfracture.
