Intended Use

The Equinoxe Shoulder System is indicated for use in skeletally mature individuals with degenerative diseases or fractures of the glenohumeral joint where total or hemi- arthroplasty is determined by the surgeon to be the preferred method of treatment. Clinical indications for the PRIMARY (P), LONG/REVISION (L), and FRACTURE (F) humeral components are as follows: [Table of indications omitted for brevity as per instructions to concatenate]. The Equinoxe Reverse Shoulder System is indicated for use in skeletally mature individuals with degenerative diseases of the glenohumeral joint and a grossly deficient, i rreparable rotator cuff. The Equinoxe Reverse Shoulder is also indicated for a failed glenohumeral joint replacement with loss of rotator cuff function resulting in superior migration of the humeral head. The Equinoxe Platform Fracture Stem is indicated for use in skeletally mature individuals with acute fracture of the proximal humerus and displacement of the tuberosities, displaced 3- and 4part fractures of the proximal humerus (hemi-arthroplasty), or acute fracture of the proximal humerus with failure of the glenohumeral joint (primary total shoulder arthroplasty). The Equinoxe Platform Fracture Stem is also indicated for acute fracture of the proximal humerus in combination with degenerative diseases of the glenohumeral joint and a grossly deficient, irreparable rotator cuff resulting in superior migration of the humeral head (reverse total shoulder arthroplasty). The Equinoxe Platform Fractures Stein is indicated for cemented use only.

Device Story

Cemented humeral stem prosthesis; designed for use with Equinoxe primary and reverse shoulder components; intended for surgical repair of acute proximal humerus fractures. Device implanted by orthopedic surgeons in clinical/hospital settings. Provides structural support for humeral reconstruction; restores joint function; facilitates fixation in cemented applications. Benefits patient by addressing fracture-related mobility loss and joint degeneration.

Clinical Evidence

Bench testing only. Dynamic compression testing performed; all constructs met criteria without failure. Engineering evaluation confirmed device sufficiency under worst-case conditions for expected life.

Technological Characteristics

Cemented humeral stem; forged titanium alloy (ASTM F136, ASTM F620). Non-constrained/semi-constrained design. Intended for cemented fixation.

Indications for Use

Indicated for skeletally mature individuals with acute proximal humerus fractures, tuberosity displacement, 3- or 4-part proximal humerus fractures, or proximal humerus fractures with glenohumeral joint failure. Also indicated for fractures combined with degenerative joint disease and irreparable rotator cuff deficiency. For cemented use only.

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).

## Exactech® Equinoxe® Platform Fracture Stem Special 510(k) - Summary of Safety and Effectiveness

- Device Shelf Life. The Equinoxe Platform Fracture Stem and the predicate device . have the identical shelf life.
### Summary of Non-Clinical Performance Data VII.

Sunmal y of Non-Chinearing evaluations were conducted to demonstrate substantial equivalence of the proposed device to the predicate Equinoxe Platform Fracture Stem

- A dynamic compression test was conducted. All constructs met the criteria without . failure.
- An engineering evaluation determined under worst case conditions that the proposed . device is sufficient to sustain clinically relevant loads during its expected life.

The results demonstrate that the proposed device is as substantially equivalent to the predicate device.
