U-Motion II E-XPE Cup Liner includes 0° and 20° hood designs, which are available in 28 mm, 32 mm, 36 mm and 40 mm inner diameter (ID). The 28 mm liners fit the acetabular cups with outer diameter (OD) ranging from 44-46 mm, the 32 mm liners fit the acetabular cups ranging from 46-50 mm, the 36 mm liners fit the acetabular cups ranging from 50-70 mm, and the 40 mm liners fit the acetabular cups ranging from 56-70 mm. The E-XPE Cemented Cup is design for cemented use and assembled with a PMMA Spacer and an X-ray marking wire. The cement mantle is built within the outer surface of acetabular cup. The PMMA Spacer is designed for cement fixation with a uniform cement thickness and the X-ray marking wire is designed for X-ray image identification purpose. E-XPE Cemented Cups are available in a range of sizes to fit varying anatomical {5}------------------------------------------------ ## C E-XPE Acetabular Components #### requirements. #### For U-Motion II Acetabular Cup The indication for use, materials, cup hole types, size distribution, sterilization method, safety and effectiveness of subject device are identical to predicate device (K122185) except the locking design. The subject device are available in sizes from 44 mm through 80 mm outer diameter in 2 mm increments. #### Intended Use: #### For E-XPE Cup Liner and U-Motion II Acetabular Cup The device is used for reduction or relief of pain and/or improved hip function in skeletally mature patients with the following conditions: - Painful, disabling joint disease of the hip resulting from: degenerative arthritis, 1. rheumatoid arthritis, post-traumatic arthritis or late stage avascular necrosis. - Revision of previous unsuccessful femoral head replacement, cup arthroplasty or other 2. procedure. - Clinical management problems where arthrodesis or alternative reconstructive 3. techniques are less likely to achieve satisfactory results. - Correction of functional deformity. 4. - Treatment of nonunion femoral neck and trochanteric fracture of the proximal femur 5. with head involvement that is unmanageable using other techniques. This device is a single use implant and intended for cementless use only. #### For E-XPE Cemented Cup - Non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, 1. ankylosis, and painful hip dysplasia; - 2. Inflammatory degenerative joint disease such as rheumatoid arthritis; - Correction of function deformity; 3. - 4. Revision procedures where other treatments or devices have failed; - 5. Treatment of nonunion and femoral neck fractures of the proximal femur with head {6}------------------------------------------------ ## C E-XPE Acetabular Components involvement that is unmanageable using other techniques. This device is a single use implant and intended for cemented use only. #### Comparison to Predicate Device: #### For E-XPE Acetabular Components The features of the subject devices are comparable to the predicate devices in terms of the same design, indication for use, locking mechanism and sterilization method expect material and size distribution. In material respect, the subject U-Motion II E-XPE Cup Liner is made from highly cross-linked Vitamin E UHMWPE (E-XPE) which is different from highly cross-linked UHMWPE (XPE) used for "UNITED" U-Motion II Acetabular System (K122185) but is substantially equivalent to "Corin" Trinity Acetabular System ECIMA Liners (K111481) and "Encore" X-alt™ Highly Cross Linked Acetabular Liner with Vitamin E (K130365). The subject E-XPE Cemented Cup is made from E-XPE, PMMA and Co-20Cr-15W-10Ni. These materials are identical with those used for "UNITED" Full XPE Cup (K163441) except E-XPE material. The size distribution of the subject devices is within the size range of "UNITED" U-Motion II Acetabular System (K122185) and "UNITED" Full XPE Cup (K163441). The differences between subject and predicate devices would not pose issues about safety and effectiveness. Non-clinical tests were also performed and the tests results demonstrate that the subject devices are substantially equivalent to the predicate devices. #### For U-Motion II Acetabular Cup The features of the subject devices are comparable to the predicate devices (K050262, K122185) in terms of the indication for use, materials, and sterilization method except the locking design and size distribution. The differences between the subject devices and predicate devices have been validated by locking strength testing to demonstrate that the subject U-Motion II Acetabular Cup does not introduce new risk of safety and effectiveness. {7}------------------------------------------------ # (9) E-XPE Acetabular Components #### Performance Data: ### ● Non-clinical Performance Tests as follows were conducted to evaluate the safety and effectiveness of the subjected device: - a. Locking Strength Test - b. Impingement Test - c. Wear Simulation Test - d. Abrasive Wear Simulation Test - Range of Motion Analysis e. - Material Properties of E-XPE Material f. - g. Bacterial endotoxin testing was conducted and met the endotoxin limit as specified in USP <161>. Performance data demonstrate the device is as safe and effective and is substantially equivalent to the legally marketed predicate devices. ### ● Clinical Performance Data/Information None provided as a basis for substantial equivalence.
