Intended Use

The Contemporary Acetabular Component is intended to be used to replace the bearing portion of the acetabulum in primary or revision total hip arthroplasty. This component is designed to be cemented into the acetabulum.

Device Story

The Contemporary Acetabular Component is an all-polyethylene acetabular cup used in total hip arthroplasty. It serves as the bearing surface for the hip joint and is designed for fixation via bone cement. The device is available in outer diameters ranging from 38mm to 80mm in 2mm increments. It is intended for use by orthopedic surgeons in a clinical or hospital setting during hip replacement procedures. The device replaces the natural acetabular bearing surface to restore joint function and mobility in patients requiring primary or revision arthroplasty.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Material: Ultra High Molecular Weight Polyethylene (UHMWPE) conforming to ASTM F-648. Design: All-polyethylene acetabular cup for cemented fixation. Dimensions: 38-80mm outer diameter in 2mm increments. Class II device (CFR 888.3350).

Indications for Use

Indicated for patients undergoing primary or revision total hip arthroplasty requiring replacement of the acetabular bearing surface.

Regulatory Classification

Identification

A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).
