Modular stem extension

The modular stem component (10) may include a shaft portion (12), a head (14), and a sleeve (16). The shaft portion (12) is configured for receipt within the intramedullary canal of a bone and the head (14) is configured to receive another component of a modular prosthetic system, such as a femoral...

Beschreibung
Zusammenfassung:	The modular stem component (10) may include a shaft portion (12), a head (14), and a sleeve (16). The shaft portion (12) is configured for receipt within the intramedullary canal of a bone and the head (14) is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib (50) defining a flange (50) extending therefrom. The sleeve (16), which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends (66,67) and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head.
