Background technology
Intertrochanteric fracture is fractured between being also known as the thick dragon of femur, is clinical most common hip it occur frequently that in the elderly
One of fracture, country's statistics account for the 35.7% of Hip Fracture.As aging population aggravates, elderly population increase, and old
People often merges osteoporosis, is more easy to fracture compared with young man under external force, and the incidence of Hip Fracture improves constantly, because
The elderly's respond declines, muscle of hip protectiveness is poor, and Hip Fracture can occur for slight damage.Pertinent literature reports stock
Bone intertrochanteric fracture accounts for Hip Fracture ratio and is even up to 50%.Intertrochanteric fracture is common in the elderly, femoral trochanteric
Blood fortune is abundant, few disunion after fracture, and expectant treatment or open reduction and Kirschner wire fixation treatment may be selected in therapeutic modality.
Expectant treatment usually needs local braking, laid up etc., and fracture end often aligns not good enough, often results in as short
Contracting, the malunion of coxa vara, have a strong impact on patients ' life quality.
Intertrochanteric fracture lateral wall correlative study is the concept just put forward in recent years, and especially it is to femoral trochanter
Between Fracture internal fixaiion stability influence, lateral wall fracture fixation is insecure, or unsuitable methods of internal fixation will cause bone
Folding, which resets, to be lost, and causes Limb Shortening and hip abduction torque shortens, pelvis equilibrant force is lost, at present between resected femur rotor
Fracture lateral wall, only lag screw and steel wire, fixed effect are imprecise.
