Grai Orthopedic Implants
Modern implants utilize advanced bearing surfaces like ceramic-on-ceramic or ceramic-on-polyethylene, which are highly wear-resistant. This greatly extends the implant's lifespan and reduces the long-term risk of revision surgery.
The product portfolio covers both hemiarthroplasty (replacing only the femoral head) and total hip replacement (replacing both the femoral head and acetabulum).
Through a modular model design system, surgeons can tailor the procedure for each patient like "assembling parts," ensuring precise fit and function.
Each product has a clear matching list that strictly defines which models of femoral heads, stems, acetabular cups, and liners can be safely combined.
| Hip Joint System | Introduction |
|---|---|
| Acetabular Cup | Implanted into the acetabulum to replace damaged articular cartilage and bone. Typically porous to encourage bone growth (osseointegration) for long-term fixation. Made of titanium or cobalt-chromium alloy. |
| Acetabular Liner | A wear-resistant insert fitted inside the metal cup. Serves as the actual bearing surface. Made from highly cross-linked polyethylene, ceramic, or metal to minimize friction. |
| Femoral Head | The spherical ball component that attaches to the femoral stem. Rotates within the liner to enable range of motion. Made of ceramic or polished cobalt-chromium alloy. |
| Femoral Stem | A rod-like component inserted into the medullary canal of the femur. Provides stability and support. Features a tapered connection for the femoral head. |
