Design and preparation of proximal femoral combination prosthesis

After the development of distal femoral and proximal tibial prostheses, the company further cooperated with Xijing Hospital to complete the design and preparation of proximal femoral prostheses, which is an important addition to the family of limb segmentary prostheses, which is of great significance for improving the product group of limb segmentary prostheses and expanding the product adaptation range. The prosthesis is composed of proximal femoral assembly (customized), backbone assembly, extended connector, rough surface thread structure and side screw hole of proximal femoral assembly and backbone assembly to provide intramedullary fixation conditions, threaded holes on the extension connector are used to connect and fix movable internal fixation system, intramedullary-extramedullary fixation can be selected on demand, good postoperative mechanical stability, and fast recovery of limb function.
