• Applicant: Howmedica Osteonics Corp.
• Product Code: KWZ · Orthopedic
• Decision Date: Mar 8, 2007
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3310
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The PCA® Constrained Acetabular Liners are intended to be used with the various components of the PCA® Total hip System in the replacement of the acetabulum and femoral head bearing surface secondary to degenerative joint disease, trauma, or failed previous prosthesis. These constrained liner components provide the surgeon with an alternative method in treating the total hip replacement patient who chronically dislocates.

Device Story

PCA® Constrained Acetabular Liners function as components of the PCA® Total Hip System; used for acetabular and femoral head bearing surface replacement. Designed for patients with degenerative joint disease, trauma, or failed previous prostheses; specifically targets patients with chronic dislocation or high risk of dislocation due to bone loss, laxity, or neuromuscular conditions. Device provides mechanical constraint to prevent hip dislocation. Used in surgical settings by orthopedic surgeons. Benefits include reduced risk of recurrent dislocation in complex revision cases.

Clinical Evidence

No clinical data provided; substantial equivalence based on design and mechanical property comparisons.

Technological Characteristics

Metal/polymer constrained acetabular liner; cemented or uncemented prosthesis. Class II device (21 CFR 888.3310).

Indications for Use

Indicated for revision total hip prosthesis patients at high risk of dislocation due to history of prior dislocation, bone loss, joint/soft tissue laxity, neuromuscular disease, or intraoperative instability.

Regulatory Classification

Identification

A hip joint metal/polymer constrained cemented or uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device prevents dislocation in more than one anatomic plane and has components that are linked together. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular component made of ultra-high-molecular-weight polyethylene with or without a metal shell, made of alloys, such as cobalt-chromium-molybdenum and titanium alloys. This generic type of device is intended for use with or without bone cement (§ 888.3027).

Special Controls

*Classification.* Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance: Hip Joint Metal/Polymer Constrained Cemented or Uncemented Prosthesis.”
