For the reconstruction of painful and/or severely disabled shoulder joints resulting from post-traumatic degenerative disease or avascular necrosis. The humeral head and neck and glenoid be of sufficient bone stock to support loading. The rotator cuff should be intact or reconstructable.

The device is a single use implant intended to be used for hemiarthroplasty or in conjunction with the Arthrosurface glenoid component for total shoulder arthroplasty.

Both humeral and glenoid components of the OVOMotion™ Shoulder Arthroplasty System are intended for cemented use only.

The OVOMotion™ Humeral prosthesis incorporates an articular resurfacing component and a taper post fixation component that mate together via a taper interlock to provide stable and immobile fixation of the implant and stress bearing contact at the bone/prosthetic interface.

The Arthrosurface OVOMotion™ Shoulder Arthroplasty System is intended as hemiarthroplasty or in conjunction with Sponsor's previously cleared and commercially marketed glenoid prosthesis (K091196) to repair and replace a shoulder joint when both articular surfaces of the joint are affected.

Humeral articular components are manufactured from CoCrMo and mate with corresponding Ti fixation component. Glenoid components are made from Ultra High Molecular Weight Polyethylene (UHMWPE). Both humeral and glenoid components are available in multiple sizes and curvatures and are intended to be implanted using bone cement.

This document is a 510(k) premarket notification for a medical device called the OVOMotion™ Shoulder Arthroplasty System. It focuses on demonstrating substantial equivalence to previously cleared devices rather than presenting a study to prove acceptance criteria for a new AI/software device.

Therefore, this document does not contain the information requested regarding acceptance criteria and a study proving a device meets those criteria, particularly for an AI/software-based medical device.

The information provided describes:

• The device: OVOMotion™ Shoulder Arthroplasty System, a shoulder arthroplasty (joint replacement) system.
• Its purpose: Reconstruction of painful and/or severely disabled shoulder joints due to post-traumatic degenerative disease or avascular necrosis.
• Materials: Humeral articular components from CoCrMo, Ti fixation components, and glenoid components from UHMWPE.
• Intended use: Hemiarthroplasty or total shoulder arthroplasty, intended for cemented use only.
• Regulatory classification: Class II medical device.
• Basis for clearance: Substantial equivalence to predicate devices (previously cleared shoulder arthroplasty systems).
• Non-clinical tests performed: Device comparative analysis, humeral head mechanical testing (Assembly & Disassembly, Resistance to Torque, Cyclic Fatigue, Fretting Corrosion, Static Compression to Failure, Shear Testing, Lever Out), and a Kinetic Chromogenic LAL Test for Bacterial Endotoxins.

None of these elements pertain to acceptance criteria for an AI/software device, clinical study data, ground truth establishment, or multi-reader, multi-case studies.
