## Intended Use

The Porous Plasma Spray (PPS) Ringloc + Acetabular System is intended to replace the natural acetabulum damaged by disease, trauma or revision of previous arthroplasty.

## Device Story

The Porous Plasma Spray (PPS) Ringloc + Acetabular System is a series of acetabular shells used in hip arthroplasty to replace a damaged natural acetabulum. The device is implanted by a surgeon in a clinical setting. It features a titanium alloy shell with a porous plasma spray coating to facilitate bone integration. The system utilizes the Ringloc + locking mechanism, allowing compatibility with Biomet's M2a Ringloc Acetabular Liners or conventional Ringloc UHMWPE liners. By providing a stable, uncemented acetabular component, the device restores joint function and addresses deformities or fractures, ultimately aiming to reduce pain and improve mobility for patients requiring hip replacement or revision surgery.

## Clinical Evidence

Bench testing only. No clinical data provided.

## Technological Characteristics

Titanium alloy shell (ASTM F-136) with porous plasma spray coating of titanium alloy powder (ASTM F-1580). Uncemented acetabular prosthesis. Features Ringloc + locking mechanism for modular liner compatibility.

## Regulatory Identification

A hip joint metal/metal semi-constrained, with an uncemented acetabular component, prosthesis is a two-part 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 consist of a femoral and an acetabular component, both made of alloys, such as cobalt-chromium-molybdenum. The femoral component is intended to be fixed with bone cement. The acetabular component is intended for use without bone cement (§ 888.3027).

## Predicate Devices

- M2a Ringloc® Acetabular Liners ([K002379](/device/K002379.md))
- Regenerex Ringloc + Modular Acetabular Shell ([K070369](/device/K070369.md))

Intended Use: The Porous Plasma Spray (PPS) Ringloc + Acetabular System is intended to replace the natural acetabulum damaged by disease, trauma or revision of previous arthroplasty.

## Indications For Use:

- 1. Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis.
- 2. Rheumatoid arthritis
- 3. Correction of functional deformity
- 4. Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques.
- 5. Revision procedures where other treatment or devices have failed.

The Porous Plasma Spray (PPS) Ringloc + Acetabular System is intended for uncemented use only.

Summary of Technologies: The subject Porous Plasma Spray (PPS) Ringloc®+ Acetabular System shells are made of titanium alloy conforming to ASTM F-136 with a porous plasma spray outer surface coating of titanium alloy powder conforming to ASTM F-1580.

Testing: Since the locking mechanism of the subject and predicate devices is identical, no testing was required to demonstrate substantial equivalence of the Porous Plasma Spray (PPS) Ringloc + Acetabular System to the predicate Regenerex Ringloc - + Modular Acetabular (1 - U - Ringlos -
