SELECT SHOULDER PEGGED ALL-POLY GLENOID by INTERMEDICS ORTHOPEDICS

The Pegged All-Poly (ASTM F648) Glenoid is a one piece design intended to reproduce the function of the natural glenoid. The design of this glenoid component allows use in the right or left shoulder. The implant is cemented into the subchondral bone of the glenoid cavity providing a cement mantle of approximately 1-2 mm.

The Pegged All-Poly Glenoid Component features a flat back, two grooved pegs and a circumferential dovetail cement groove on the medial surface to provide translational and rotational stability to the implant as well as to enhance cement fixation. The peg grooves allows for intraoperative trimming in the event of shallow glenoid anatomy. The concave lateral surface of the glenoid implant accommodates the humeral head. The geometry of the component is nonconstrained. Titanium pins in the inferior and superior aspects of the component assist in postoperative evaluation.

AI/ML Overview

This 510(k) summary describes a medical device (Intermedics Orthopedics, Inc. Select® Shoulder All-Poly Glenoids) and does not contain information about a study proving its performance against acceptance criteria in the context of an AI/algorithm-driven device. Therefore, I cannot extract the requested information.

The document describes a physical medical implant (a glenoid prosthesis) and discusses its design, materials, and substantial equivalence to other existing glenoid prostheses on the market. It mentions "contact area testing" but provides no details on acceptance criteria, reported performance values, study design, sample sizes, expert involvement, or any of the other AI/algorithm-specific metrics requested.

Classification Name:	21 CFR Part 888.3650 - Shoulder joint metal/polymer non-constrained cemented prosthesis
Common/Usual Name:	Glenoid prosthesis
Trade/Proprietary:	Select® Shoulder Pegged All-Poly Glenoids

Product Description/Substantial Equivalence:

Contact area testing indicated that the Pegged All-Poly Glenoids offer adequate contact area at various levels of abduction.

The designs are substantially equivalent to the glenoids used in the Orthomet/3M Modular Neer II Shoulder System, the Zimmer Fenlin Total Shoulder, the Smith & Nephew Richards Coffield Shoulder, the Kirschner/Biomet Modular Shoulder, the Biomet Bio-Modular Total Shoulder, and the Depuy Global Total Shoulder System.

Regulation Number and Section

§ 888.3650 Shoulder joint metal/polymer non-constrained cemented prosthesis.

(a)
Identification. A shoulder joint metal/polymer non-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder joint. The device limits minimally (less than normal anatomic constraints) translation in one or more planes. It has no linkage across-the-joint. This generic type of device includes prostheses that have a humeral component made of alloys, such as cobalt-chromium-molybdenum, and a glenoid resurfacing component made of ultra-high molecular weight polyethylene, and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II. The special controls for this device are:(1) FDA's:
(i) “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Devices—Part I: Evaluation and Testing,’ ”
