## Intended Use

The ULTIMA Fx Femoral Hip Stem is indicated for use in total or partial hip replacement procedures for patients suffering severe pain and disability due to structural damage in the hip joint from rheumatoid arthritis, osteoarthritis, post-traumatic arthritis, collagen disorders, avascular necrosis, traumatic and non-union of femoral fractures. Use of the prosthesis is also indicated for patients with congenital hip dysplasia, protrusio acetabuli, slipped capital femoral epiphysis, and disability due to previous fusion, where bone stock is inadequate for other reconstruction techniques.

## Device Story

ULTIMA Fx Femoral Hip Stems; cemented and uncemented designs; manufactured from cobalt-chromium-molybdenum (Co-Cr-Mo) alloy. Used in total or partial hip replacement procedures; implanted by orthopedic surgeons in clinical settings. Stems mate with P.F.C. or ULTIMA Unipolar hip heads (10/12 taper). Provides structural support for hip joint; restores joint function; alleviates pain/disability caused by arthritis, fractures, or congenital conditions. Cemented version includes cobra flange; press-fit version designed for uncemented fixation.

## Clinical Evidence

Bench testing only; no clinical data provided.

## Technological Characteristics

Materials: Cobalt-chromium-molybdenum (Co-Cr-Mo) alloy. Design: Cemented (8-11mm distal diameter, 130-165mm length, 2.0-3.6mm cement mantle, 37-46mm offset, cobra flange) and uncemented/press-fit (10.5-15mm distal diameter, 125-165mm length, 34-46mm offset). Interface: 10/12 taper for hip head attachment.

## Regulatory 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) or implanted by impaction.
