The Select Shoulder Humeral Stem is a metallic humeral component manufactured from cobalt chrome alloy (CoCrMo) and is intended for use with bone cement in total shoulder arthroplasty. The humeral stem is available in a variety of sizes and features a proximally grit blasted surface (except for the head stem taper) for enhanced cement fixation. The proximal trapezoidal shape tapers in the A-P plane, thus providing for a stable cement mande. The proximal body also features an antirotation fin on the lateral aspect. Suture holes are provided in the medial proximal body and lateral fin to allow for soft tissue/bony fragment attachment and tensioning, thus resulting in a more biomechanically stable construct for repair for proximal fractures. A male IOI morse type taper permits attachment of one of the metallic humeral heads offered by Intermedics Orthopedics. This taper is identical to the taper of the previously cleared Select Shoulder System. Distally, the stem is rounded and fluted to provide enhanced fixation and rotational stability. The distal stem tip is designed to accept a cement centralizer. The humeral stem is designed for use with Intermedics Orthopedics humeral heads and glenoid components in a variety of sizes and heights for increased stability of the glenohumeral joint.
This document is a 510(k) summary for a medical device (Intermedics Orthopedics, Inc. Select® Shoulder System CoCr Humeral Stem) and describes its physical characteristics and intended use. It does not contain any information about acceptance criteria or a study proving the device meets acceptance criteria related to AI/ML performance.
Therefore, I cannot fulfill your request for information regarding:
- A table of acceptance criteria and the reported device performance
- Sample size used for the test set and the data provenance
- Number of experts used to establish the ground truth for the test set and their qualifications
- Adjudication method
- Multi-reader multi-case (MRMC) comparative effectiveness study
- Standalone performance
- Type of ground truth used
- Sample size for the training set
- How the ground truth for the training set was established
The provided text focuses on the mechanical and material properties of a humeral stem and its equivalence to other legally marketed devices, rather than on the performance of an AI/ML algorithm.

Fatigue analysis and taper testing of the Select Shoulder Humeral Stem indicated that the device would survive physiologic loading.
The Select Shoulder CoCr Humeral Stem is similar to those of the Depuy Global Total Shoulder System, the Biomet Bio-Modular Total Shoulder, the Zimmer Fenlin Total Shoulder, the Kirschner Integrated Shoulder System, the 3M/Orthomet Neer II Shoulder System, and the Smith

§ 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:
