Description
Technical field
The present invention relates to a kind of memorial alloy greater trochanter girdle device.
Background technology
Intertrochanteric fracture of the femur was suffered from also known as intertrochanteric fracture, the advanced age being more common in more than 60 years old clinically
Person.Senile osteoporosis phenomenon is serious, easily causes fracture.Treatment of Intertrochanteric Fractures in Aged Patients wound
It is caused that case intertrochanteric fracture of the femur wound mostly is violence damage.Such as traffic accident wound, traumatic injury, crush injury
Fracture caused by the direct external force of hip etc. is caused with unexpected incidents.Its account for whole body fracture 4.5%, the most not
Stable fracture accounts for 35%～40%.The idea of traditional treatment fracture of rib was in the past, thick to old people's femur
Grand fracture takes expectant treatment more, and this kind of Therapeutic Method cycle will be between multiple moons and half a year, time long
Between bed cause patient not only painful but also costly, the complication producing lung and other internal organs is many, causes
Mortality rate increases.Along with the maturation of artificial joint technology, Treatment of Intertrochanteric Fractures in Aged Patients is taked more
Replacement of Hip Joint.But greater trochanter portion bone piece fixes the difficult problem become in current clinic, fragmentation
The abduction muscle group attachment point of hip joint is adhered on greater trochanter.As fixing bad meeting causes hip joint after operation in patients
Abduction function is poor.In art, many crushing according to patient bone broken line and bone piece asks money to use ulna far-end wound at present
Fixation steel plate or proximal humeral steel plate are fixed, because steel plate design is not directed to femoral greater trochanter portion fracture
Fixing, art need more secondary moulding, although fixation can be reached, can but steel plate secondary is moulding
The problems such as energy can bring steel plate form matching degree low, intensity reduction.And tuberosity bone piece is little, screw is fixing tired
Femoral stem occupy-place in pulp cavity in the middle part of difficulty, and femur, Interal fixation screw can only be fixed by mono cortex, and
And need to prevent screw long scuffing type femoral bone end prosthesis face coat.The best fixing device becomes
For in Treatment of Intertrochanteric Fracture problem in the urgent need to address.
Summary of the invention
It is an object of the invention to provide one and can reliably and efficiently hold fixing greater trochanter, art is not required to
Wanting excessive prolonged incison, can shorten operating time, reduce amount of bleeding, operation technique is simple, convenient,
Can effectively substitute and existing intertrochanteric fracture patient's hip replacement use the memory of greater trochanter steel plate close
Gold greater trochanter girdle device.
