Intended Use

The Anatomical Shoulder System is intended for long-term implantation into the human shoulder joint in primary or revision, total or hemi shoulder arthroplasty. The system is intended to relieve pain and restore function in patients with adequate bone stock to support the prosthesis. The ASHCOM Shoulder System is intended for reverse shoulder arthroplasty.

Device Story

Modular shoulder prosthesis system; includes humeral stems, glenoid components, and ASHCOM AC-Connector. AC-Connector acts as double-tapered adapter allowing combination of Anatomical Shoulder Humeral Stems with Comprehensive Reverse Trays. Used in primary, revision, or fracture shoulder arthroplasty to relieve pain and restore function. Implanted by orthopedic surgeons in clinical/hospital settings. Provides structural replacement of shoulder joint; enables reverse configuration for patients with gross rotator cuff deficiency. Labeling update adds MR Conditional status for existing and new components.

Clinical Evidence

No clinical data. Substantial equivalence demonstrated via non-clinical performance testing including finite element stress analysis, cyclic fatigue testing, accelerated corrosion fatigue testing, and static taper connection testing (ASTM F2009). MRI compatibility evaluated per FDA guidance.

Technological Characteristics

Modular shoulder prosthesis; materials include metal and polymer. Features double-tapered AC-Connector. Static taper connection testing performed per ASTM F2009. MR Conditional labeling applied per FDA guidance for passive implants.

Indications for Use

Indicated for patients requiring primary, fracture, or revision total/hemi shoulder arthroplasty due to degenerative, posttraumatic, or rheumatoid arthritis, avascular necrosis, omarthrosis, cuff-tear arthropathy, or complex proximal humerus fractures. Requires adequate bone stock and functional deltoid muscle for reverse applications.

Regulatory Classification

Identification

A shoulder joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder 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 have a humeral resurfacing 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).

Comparison to Predicate Device: The ASHCOM AC-Connector allows the combination of the Anatomical Shoulder Humeral Stems with the Comprehensive Reverse Trays. The indications are shared with the reverse application of the Anatomical Shoulder predicate device. The ASHCOM AC-Connector utilizes the same material as the Anatomical Shoulder Humeral Stem and the same manufacturing process, and has similar technical features as the Anatomical Shoulder predicate device. This submission further covers a labeling modification to the existing Anatomical Shoulder and Anatomical Shoulder Combined System. The labeling modification consists of the addition of Magnetic Resonance Imaging (MRI) compatibility information to the Package Insert, and application of the "MR {9}------------------------------------------------ Conditional" symbol on the package label. No other changes are proposed. Performance Data (Nonclinical and/or Clinical): Results of non-clinical performance testing and analyses demonstrate that the ASHCOM Shoulder System is safe and effective and substantially equivalent to the predicate devices. Performance analyses included: 1. Finite Element Stress analysis and cyclic fatigue testing under worst case conditions 2. Accelerated Corrosion Fatigue Testing 3. Static taper connection testing according ASTM F2009 The components of the ASHCOM Shoulder System, the Anatomical Shoulder System and the Anatomical Shoulder Combined System and have been evaluated for compatibility in the MRI environment, per Guidance for Industry and FDA Staff, "Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment", August 2014. Based upon the results, the subject shoulder implants are recommended to bear the "MR Conditional" labeling and include MR compatibility safety information within the package insert. Clinical Performance and Conclusions: Clinical data and conclusions were not needed to demonstrate substantial equivalence.
