Hip Joint System | Introduction |
Acetabular Cup | This is the "bowl" or "socket" component of an artificial hip joint. It is implanted by the surgeon into the acetabulum (the socket of the pelvis) to replace the damaged original articular cartilage and bone. The cup is typically porous to encourage bone growth into it (osseointegration) for long-term fixation. It is usually made of metal (e.g., titanium or cobalt-chromium alloy). |
Acetabular Liner | The liner is a wear-resistant insert that is securely fitted inside the metal acetabular cup. It serves as the actual bearing surface of the hip joint. The femoral head articulates (moves) against this liner. It is commonly made from highly cross-linked polyethylene, ceramic, or metal to minimize friction and wear. |
Femoral Head | The head is the spherical ball component that attaches to the tapered neck of the femoral stem. It replaces the natural femoral head of the femur. This ball rotates within the acetabular liner, enabling the hip's range of motion (flexion, extension, rotation, etc.). It is typically made of a smooth, hard material like ceramic or polished metal (cobalt-chromium alloy). |
Femoral Stem | The stem is the long, rod-like component that is inserted into the medullary canal of the femur (thigh bone). It provides stability and structural support for the entire femoral component. Its top end features a tapered connection (a taper) to which the femoral head is attached. Stems are usually made from titanium or cobalt-chromium alloys and may have coatings or porous surfaces to facilitate bone ingrowth. |
