The C2 uncemented stem represents a Zweymuller philosophy stem optimized to allow for use in primary and simple revision cases. On the market since 1996, the C2 Stem is indicated for cases where strong cortical contact is preferred. The calcar region of the stem has been optimized with a rounded profile to allow for even distribution of the loads and reduce the risk of calcar resorption. The blunt tip reduces risk of distal contact with consequent reduction of thigh pain occurrence. C2 stem presents a special machining treatment in the proximal profile that increases the contact surface with the bone for a solid and stable secondary fixation.
