Description
Technical field
The invention belongs to technical field of medical instruments, relate in particular to a kind of device for the treatment of femur head necrosis.
Background technology
Femur head necrosis is blood supply of the femoral head interruption or impaired, causes osteocyte and the death of bone marrow composition and reparation subsequently, then causes the disease of femoral head structural change, collapse of the femoral head, joint function disturbance.Femur head necrosis (osteonecrosis of the femoral head, ONFH) claim again ischemic necrosis of femoral head (avascularnecrosis, AVN), is the common refractory disease in orthopaedics field.ONFH can be divided into the traumatic and large class of atraumatic two, and the former is caused by the hip such as fracture of femoral neck, dislocation of hip joint wound, application and excessive drinking that the latter is corticosteroid in the main cause of China.Along with the development of economic society, wound increases, is addicted to drink, the abuse of hormone, and the many factors such as the rising of disease of immune system sickness rate, causes femur head necrosis rate progressively to rise.The cardinal symptom of femur head necrosis, progressively develops into rest pain from discontinuity pain, then causes muscle spasm, joint motion by pain and be restricted, and finally causes seriously to disable and walk lamely.The treatment of femur head necrosis is the difficult problem that current orthopaedics faces, though its Therapeutic Method is many, but curative effect is all dissatisfied, often further develop to subsiding or subsiding of making to have existed further increased the weight of, finally cause long-term pain or and the useless use of hip joint and have to carry out hip replacement surgery.
Along with scientific and technological progress, to the diagnostic method of femoral head osteonecrosis, also at gradual perfection, and Therapeutic Method is varied especially.At present, for the Therapeutic Method of femoral head necrosis, be mainly divided into Noninvasive and invasive treatment, its main purpose is all to improve the blood fortune of femur head necrosis district sclerotin, promotes the reparation of necrotic area sclerotin, to reach the object of clinical treatment.
To the early stage treatment of femur head necrosis, a kind of common Therapeutic Method is marrow core drilling decompression, its method is to after patient's administration of anaesthetic, under X-ray examination, keep certain collodiaphyseal angle and top rake to femoral head internal drilling in femoral greater trochanter below, make Kirschner wire tip arrive 4-5mm under femoral head cartilage, in femoral head, neck of femur, make osseous tunnel, reach the object of decompression.Though the method has certain curative effect, but still there are a lot of weak points: the one, operation wound is larger, and to neck of femur internal skeleton, tissue injury is larger, total bone injury volume large (damage of the bone drill volume of three times or more times); The 2nd, can only be determined by the direction of inserting needle in the direction of necrotic area decompression, change direction and need to increase again the osseous tunnel of squeezing into necrotic area; The 3rd, postoperative patient further subsides for fear of the rear femoral head that bears a heavy burden, and needs the bed of long period.
In current various Therapeutic Method, how major part improves capital blood confession and promotes capital reparation if concentrating on, and relatively less to how preventing its research of subsiding.The method that prevents collapse of the femoral head and make the femoral head that subsided recover normal morphology comprise utilize after windowing or holing apparatus from inside to outside jack-up subside after cartilage and implant cortical bone, or implant and remember titanium alloy reticulated, the elasticity of utilizing the refresh memory of memory titanium alloy reticulated to have, supports the femoral head subsiding.
Summary of the invention
