Abstract

The invention belongs to the field of medical instruments, and particularly relates to a tibial prosthesis. The provided tibial prosthesis comprises a tibial replacement part and a fixing part, wherein the fixing part is used for fixing the tibial replacement part and a healthy bone in a preset replacement position, and the tibial prosthesis is a 3D-printed tibial prosthesis; and the tibial replacement part comprises a tibia medullary cavity insertion unit, a load-bearing unit and a talus fixing unit which are sequentially connected. According to the tibial prosthesis, the 3D-printed personalized distal tibial prosthesis is designed and placed according to CT data or nuclear magnetism data of an invasion range of a removed focus, compared with allogeneic bones and tibial plates used in theprior art, the tibial prosthesis has good stable reliability, moreover, surgery is more precise, the surgical difficulty and risks are greatly reduced, the surgery time is shortened, and recovery ofa patient is more facilitated; and the defects that in the prior art, during bone reconstruction, quick healing cannot be achieved, and good initial stability and long-term stability cannot be ensuredare overcome, and it is further ensured that the patient has good knee joint functions after the surgery.

Description

technical field

[0001] The invention belongs to the field of medical instruments, in particular to a tibial prosthesis. Background technique

[0002] The tibia, as an important load-bearing bone in the human body, is the main component of the lower limbs. As important components of the ankle-hindfoot complex, the tibiotalar joint and subtalar joint are responsible for maintaining the weight-bearing walking of the lower limbs and maintaining normal ankle mobility.

[0003] However, ankle or hindfoot trauma and malignant bone tumors and other diseases may cause secondary tibiotalar joint and subtalar joint lesions, causing severe pain and walking dysfunction. For patients who cannot achieve satisfactory results with conservative treatment, surgery Treatment can provide better pain relief and restore function. If the lesion is completely resected and the distal tibia and ankle joint are replaced, the distal tibia and ankle joint on the affected side will be destroyed, which w...
