Modular hip joint prosthesis

摘要

The modular hip prosthesis has an axial stem forming its distal part. Two modular proximal parts can be mounted on the stem from its proximal end and be rigidly connected thereto. Because the prosthesis has two modular parts at its proximal end, it can be optimally adapted to match the bone geometry intraoperatively. The diameter of the prosthesis in its proximal part and the position of the hip joint can be defined independently. Due to its slim shape and a drain for medullary material, the stem can directly be driven into the bone and does not require a pre-drilled cavity.
