The Full XPE cup offers the surgeon all the benefits of a cemented all polyethylene cup with the added advantage of optimized head-to-cup ratio and a proven cross-linked polyethylene articulation. The full XPE cup incorporates a 20° lip, a pressurizing flange and horizontal and vertical grooves for cement fixation. The PMMA spacers ensure adequate cement mantle whilst the X-ray marker assists with detecting cup position post-operatively.

Enhanced joint stability:
The Full XPE™ cup optimises head and cup size ratio, allowing for the use of larger heads when compared with conventional systems; thus enhancing hip joint stability, range of motion and reducing risk of dislocation. Evidence demonstrates that the larger head paired with the XPE™ Cup allows for 178° ROM without impingement[1]. In addition, the 20° lip further reduces the risk of joint dislocation in patients with poor soft tissue stability.
UOC’s XPE™, highly cross-linked polyethylene material has demonstrated 89% reduction in wear rates when compared with conventional polyethylene thereby providing a long lasting, all polyethylene cup solution[2].
