Description
Technical field
The invention belongs to medical instruments fields, and in particular to a kind of fixed dress of screw placement for fracture of neck of femur model
It sets.
Background technique
Fracture of neck of femur is fracture of the femoral head between femoral trochanter, accounts for the 3.6% of adult whole body fracture.Lead to stock
The reason of bone fracture of cervical vertebra be it is various, as people's lives Quality advance and service life extend, Aging Problem is had become sternly
The social concern of weight, and in elderly population, osteoporosis accounting is high, bone biomechanical fragile structure, shows as bone trabecula change
Carefully, bone amount reduce, thus fracture of neck of femur be more common in, the elderly.In addition, this kind of crowd be also possible to because muscle group regression or
Other underlying diseases and cause risk of bone fracture to dramatically increase.After patient fractures, except the suffering limb that may be showed is lopsided, affected part
Outside pain and swelling, serious person usually has normal stand and is influenced on foot, and which results in the great physical pain of patient and the hearts
Reason burden, particularly with older patient, the risk performed the operation after fracture is also dramatically increased.
Treatment of femoral neck fracture means include traction, interior fixation and prosthetic replacement etc., however, fracture of neck of femur is often
It is difficult to obtain satisfied reset and fixation, and then leads to serious complication, influence prognosis, this also further increases fracture hand
The difficulty of art.When implementing internal fixation operation of cutting and resetting, under X-ray examination, after resetting satisfied, commonly use positive triangle mode or
Inverted triangle mode is squeezed into three forcing screws and is fixed, because such mode configuration intensity is larger, while to local blood supply shadow
Sound is relatively small.Also there is related mechanical test to carry out the fixed effect of the different fixed forms of comparison or different screws simultaneously, but is making
Make to will appear during fracture of neck of femur model screw placement that screw is not parallel, the situation inconsistent into nail position.
