Device Description

The Consensus Acetabular Shell System consists of four modular shell options which mate with currently marketed polyethelyne insert components for replacement of the acetabular surface during total hip arthroplasty. The shells are designed to be implanted without bone cement. Cementless (press-fit) fixation is achieved by coating the external surface of the cup with commercially pure (CP) titanium sintered beads.

All of the shell options have the following common features:

The substrate material of the Consensus Shells is titanium alloy (ASTM F136, Ti-6AI-4V) ●
· The shell is porous coated with commercially pure (CP) titanium sintered beads (ASTM F67, irregular bead geometry).
· The shells have the same internal locking mechanism as the previously cleared Consensus Acetabular Shells (K922561).
· The apical dome hole of the shells is threaded to accept an impaction tool for implanting the component. After implantation and the impaction tool is removed, a threaded titanium (ASTM F67 or F136) hole plug can be inserted into the threaded hole to prevent migration of unwanted particles through the dome hole.

The following shell options are available:

· Total Hemispherical in no screw holes or three (3) quadrant screw holes options.
· Hemispherical with rim flare in no screw holes or three (3) quadrant screw holes options.

AI/ML Overview

I am sorry, but the provided text does not contain information about the acceptance criteria or a study that proves the device meets specific criteria. The document is a 510(k) summary for a medical device (Consensus Acetabular Shell System), which primarily focuses on device description, intended use, and demonstrating substantial equivalence to previously cleared predicate devices.

Therefore, I cannot provide the requested table or answer the specific questions about sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, or ground truth establishment based on this text.

Comparison to Cleared Device

The following changes have been made to the previously cleared Consensus Acetabular Shell (K922561):

Addition of the Hemisphical with rim flare outer profile .
Removal of the two inferior screw holes. Holed cups now have three instead of five screw holes. .
The apical dome hole has been threaded. .
. A threaded apical dome hole plug is now available.
. The porous coating is being modified from a spherical sintered CP titanium bead to an irregular sintered CP titanium bead.

The locking mechanism between the polyethylene (UHMWPE) liner and the acetabular shell is identical to the previously cleared Consensus Acetabular Shell (K922561). The safety and effectiveness of this locking detail is described in testing contained within the original submission.

Substantial Equivalence Information

The intended use, material, design features and type of interface of the Consensus Acetabular Shell System are substantially equivalent to competitive devices previously cleared for market. The safety and effectiveness of the Consensus Acetabular Shell System are adequately supported by the substantial equivalence information and materials data provided within this Special 510(k) submission.

Regulation Number and Section

§ 888.3358 Hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis.

(a)
Identification. A hip joint metal/polymer/metal semi-constrained porous-coated uncemented 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 has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.(b)
Classification. Class II.
