Embodiment Construction

[0418] figure 1 is a schematic top view of the human acetabulum 1 , also known as the hip socket or cotyloid cavity. It is the bony part of the hip joint formed by the pelvis. The acetabulum is formed by the partial fusion of the ischium, ilium, and pubic bone. This fusion is complete at about 6 months of age.

[0419] Ideally, the acetabulum and the femoral head correspond to each other, ie the round femoral head fits precisely into the acetabulum, which inserts and encloses it over a wide area. The hip joint is a polyaxial ball and socket joint, and is therefore more or less free to move in almost any direction. This ensures high mobility and carrying capacity.

[0420] The arthritic part of the hip joint is surrounded by a capsule of connective tissue, which is lined with synovium, which is constantly producing new synovial fluid. The edge of the bone socket is formed by a circular articular lip composed of cartilage.

[0421] The acetabulum 1 has an anterior acetabul...

Abstract

The invention relates to an implant, especially for treating a bone defect. The implant has osteoconductive support bodies and an insertion aid. The insertion aid is designed for insertion of the osteoconductive support bodies into a bone defect and for holding together the osteoconductive support bodies. The invention also relates to a kit.

Description

technical field [0001] The present invention relates to implants and kits for the treatment of bone defects. Background technique [0002] Large acetabular bone defects are a major concern in revision hip surgery. In hip revision surgery, the three main goals are as follows. [0003] First, the original joint center must be restored. [0004] Another object is the stable fixation of implants for the treatment of bone defects. In the fixation of implants, a distinction is usually made between so-called primary stability and so-called secondary stability. [0005] Primary stability is understood to mean the fixation of the implant during the first few weeks after the surgical procedure due to friction or fastening elements such as eg bone screws. Secondary stability is understood to mean implant fixation based on osteosynthesis. Secondary stabilization is usually achieved about a month after surgery and can last for up to several years. [0006] The final goal is the bio...
