# §888.3390. Hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis.

- (a) **Identification.** A hip joint femoral (hemi-hip) metal/polymer cemented or uncemented prosthesis is a two-part device intended to be implanted to replace the head and neck of the femur. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a snap-fit acetabular component made of an alloy, such as cobalt-chromium-molybdenum, and ultra-high molecular weight polyethylene. This generic type of device may be fixed to the bone with bone cement ([§ 888.3027](/cfr/21/888.3027.md)) or implanted by impaction.
