Abstract

The invention relates to the field of artificial prosthesis replacement, in particular to an anatomical bionic tibia near-end tumor semi-knee joint prosthesis which comprises a tibia near-end prosthesis and an artificial ligament, and the tibia near-end prosthesis is provided with ligament through holes and ligament fixing grooves. The artificial ligament comprises an anterior cruciate ligament, a posterior cruciate ligament, a medial collateral ligament and an lateral collateral ligament which are respectively connected in the corresponding ligament fixing grooves of the proximal tibia prosthesis. The anatomical bionic tibia near-end tumor semi-knee joint prosthesis adopts a unipolar design, the movement function of the knee joint can be recovered by reasonably fixing the ligament, meanwhile, thighbone side epiphysis and surrounding tissues are reserved as much as possible, the bone growth function of young patients can be guaranteed while the movement function of the knee joint is reconstructed, and the stability of joint movement is maintained.

Description

technical field [0001] The invention relates to the field of artificial prosthesis replacement, in particular to an anatomical bionic proximal tibial tumor half-knee joint prosthesis. Background technique [0002] Malignant bone tumors often occur in the long bones of the extremities, and the principle of extensive resection should be followed in clinical practice. For example, bone tumors occur in the proximal tibia, and surgical resection will lead to defects in the proximal tibia, accumulating knee joints and causing knee joint dysfunction. At present, the hinged tumor-type knee replacement is the most commonly used surgical reconstruction method. The hinge-type tumor-type knee prosthesis needs to resect the proximal tibia and part of the distal femur to place the prosthetic components at the same time. Involvement of the distal femoral epiphysis. Osteosarcoma most often occurs in young people under the age of 20, especially children. The epiphysis of this group has not ...
