Intended Use

The Pinnacle Metal-On-Metal Acetabular Cup Liners are indicated for use as the acetabular component in total 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, 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.

The Pinnacle Metal-On-Metal Acetabular Cup Liners are intended for use with DePuy Pinnacle Acetabular Shells and M-Spec Co-Cr-Mo femoral heads only.

Device Description

The Pinnacle Metal-On-Metal (MOM) Acetabular Cup Liner is a metal liner that is intended for use with Pinnacle Acetabular Shells that have been cleared previously. The liners currently are offered with inner diameters (ID) of 28-36mm, this modification is to add 40 and 44mm Ids and to add a 36mm liner with a outer diameter (OD) of 50mm. The liners are offered in a neutral style only. The subject Pinnacle MOM liner is mechanically locked with the shell via a taper junction which is identical to the taper junction used for the cleared 28 and 36mm liners and articulates with previously cleared M-Spec metal prosthetic femoral heads.

AI/ML Overview

The provided text is a 510(k) summary for the DePuy Pinnacle Metal-on-Metal Acetabular Cup Liners. This document focuses on demonstrating substantial equivalence to previously cleared devices rather than presenting a study with specific acceptance criteria and performance data for a device.

Therefore, I cannot provide the requested information regarding acceptance criteria and a study proving a device meets those criteria, as this information is not contained within the provided text. The document is for a medical device that has been cleared through the 510(k) process, which relies on demonstrating substantial equivalence to a predicate device, not on meeting predefined performance criteria through a new study.

§ 888.3330 Hip joint metal/metal semi-constrained, with an uncemented acetabular component, prosthesis.

(a)
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).(b)
Classification. Class III.(c)
Date PMA or notice of completion of PDP is required. A PMA or a notice of completion of a PDP is required to be filed with the Food and Drug Administration on or before May 18, 2016, for any hip joint metal/metal semi-constrained prosthesis with an uncemented acetabular component that was in commercial distribution before May 28, 1976, or that has, on or before May 18, 2016, been found to be substantially equivalent to a hip joint metal/metal semi-constrained prosthesis with an uncemented acetabular component that was in commercial distribution before May 28, 1976. Any other hip joint metal/metal semi-constrained prosthesis with an uncemented acetabular component shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.
