Device Description I Total Hip Arthroplasty (THA) has become one of the most successful treatments in orthopedics; having both good patient satisfaction and long-term survivorship. However, challenging problems still exist-especially for physically active individuals-ranging from postoperative dislocation, bearing wear, and insufficient range of motion. The U-Motion II + Acetabular System uses improved implant materials, BIOLOX ® delta ceramic heads, highly cross-linked polyethylene (XPE) and Vitamin E stabilized highly cross-linked polyethylene (E-XPE) liners. With this unique material technology, the U-Motion II + Acetabular System offers larger femoral head sizes to improve hip flexion and to reduce the risk of joint dislocation. The U-Motion II + acetabular liner accommodates both ceramic and metal heads. Bearing options with 28 mm, 32 mm, 36 mm and 40 mm articulation diameters are available in the U-Motion II + Acetabular System. Full range of acetabular cup size from 44 mm to 70 mm (in 2 mm increments) supports the variety of acetabular anatomy. TPS Plus TM surface coating increases the roughness of the implant and provides initial stability of acetabular component. The enhanced grip of the interface allows immediate bone and implant interlocking further contributing to bone ingrowth. The advanced acetabular system grants orthopedic surgeons flexibility during surgery for addressing clinical problems they might meet.
