Description
Technical field
Ankle, which is protected, the present invention relates to the field of medical instrument technology more particularly to assembly type protects knee tibial shaft prosthese.
Background technique
The site of pathological change of malignant bone tumor is common with femur and tibial metaphysis, especially common with knee joint peripheral.Pernicious bone
Tumor invasion age level is common with children and teenager.Shin bone is kneed main composition portion as important load-bearing bone
Point.By the application of new adjuvant chemotherapy and adjuvant chemotherapy, early diagnosis and multidisciplinary assistance, so that 5 years survival rates have been approached
80%.The implementation of new surgical technic, the higher functional requirement of patient, the raising of prosthetic designs level, novel imaging technique go out
It is existing, make it possible the existing conventional treatment mode of limb-sparing surgery.
But at present for the processing mode of child or adolescent's proximal tibia malignant bone tumor are as follows: complete resection tumour
Afterwards, tibial neoplasms knee prosthesis is carried out.Which will destroy the metaphysis of Ipsilateral proximal tibia and distal femur, to Ipsilateral bone
Growth effect is huge, will lead to leg length discrepancy, walks lamely, the later period need to repeatedly carry out revision procedure.Both want to guarantee patient's itself
Knee joint, and want to rebuild bone defect, it is that existing prosthese is unappeasable.When the tumour of complete resection proximal tibia, while can be with
When complete reservation proximal tibia epiphysis, it is desirable to obtain good initial stability at once, while so that interface is quickly healed again, also
Guarantee good stability at a specified future date and good knee joint function, is a current research emphasis.
