Intended Use

Hemiarthoplasty/Conventional Total Application: - Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis. - Rheumatoid arthritis. - Correction of functional deformity. - Fractures of the proximal humerus, where other methods of treatment are deemed inadequate. - Difficult clinical management problems, including cuff arthropathy, where other methods of treatment may not be suitable or may be inadequate. Optional use in revision: in some medical conditions (e.g. revision when healthy and good bone stock exists), the surgeon may opt to use primary implants in a revision procedure. Reverse Application: Zimmer Biomet Reverse Shoulder products are indicated for use in patients whose shoulder joint has a grossly deficient rotator cuff with severe arthropathy and/or previously failed shoulder joint replacement with a grossly deficient rotator cuff. The patient must be anatomically and structurally suited to receive the implants, and a functional deltoid muscle is necessary. The Zimmer Biomet Reverse Shoulder is indicated for primary, fracture, or revision total shoulder replacement for the relief of pain and significant disability due to gross rotator cuff deficiency. The assembled humeral component may be used alone for hemiarthroplasty or combined with the glenoid component or reverse components for total shoulder arthroplasty (conventional or reverse applications). The humeral components may be used cemented or uncemented (biological fixation). The Titanium Humeral Head and Glenosphere components are indicated for patients with suspected cobalt alloy sensitivity. The wear properties of Titanium and Titanium alloys are inferior to that of cobalt alloy. A Titanium humeral head or Glenospheres not recommended for patients who lack suspected material sensitivity to cobalt alloy. Comprehensive Nano Stemless Shoulder System: 1. Primary total shoulder arthroplasty. 2. Non-inflammatory degenerative joint disease including osteoarthritis. Comprehensive Nano Stemless Shoulder humeral components have a porous coated surface coating and are indicated for uncemented biological fixation applications. The Comprehensive Modular Hybrid Glenoid is intended to be implanted with bone cement. The porous titanium peg may be inserted without bone cement.

Device Story

Comprehensive Humeral Head Adapter (CHHA) serves as line extension to Identity Shoulder System; provides modularity/adaptability for glenohumeral joint restoration. Device acts as interface component; enables compatibility between Identity Humeral Heads and existing Comprehensive humeral stems/Nano Stemless shoulder components. Used in orthopedic surgery; implanted by surgeons in clinical settings. Facilitates anatomic total shoulder arthroplasty or hemiarthroplasty. Benefits patient by allowing individual anatomical adjustment; restores joint function; provides alternative for patients with cobalt alloy sensitivity. Output is physical structural support for shoulder joint; assists in pain relief and restoration of mobility.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by non-clinical verification testing including fatigue, fretting, corrosion, fixation stability, range of motion (ROM), static modular junction strength, and MRI compatibility.

Technological Characteristics

Modular humeral head adapter; metallic construction consistent with predicate shoulder systems. Features porous-coated surfaces for biological fixation (uncemented) or cemented options. Designed for compatibility with existing humeral stems and heads. Sterilization and packaging identical to predicate. No software or active energy source.

Indications for Use

Indicated for patients requiring primary, fracture, or revision total shoulder arthroplasty or hemiarthroplasty due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or cuff arthropathy. Reverse application indicated for patients with grossly deficient rotator cuff and severe arthropathy or failed prior replacement; requires functional deltoid muscle. Titanium components indicated for patients with suspected cobalt alloy sensitivity.

Regulatory Classification

Identification

A shoulder joint metal/polymer/metal nonconstrained or semi-constrained porous-coated uncemented prosthesis is a device intended to be implanted to replace a shoulder joint. The device limits movement 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 (Co-Cr-Mo) and titanium-aluminum-vanadium (Ti-6Al-4V) alloys, and a glenoid resurfacing component made of ultra-high molecular weight polyethylene, or a combination of an articulating ultra-high molecular weight bearing surface fixed in a metal shell made of alloys such as Co-Cr-Mo and Ti-6Al-4V. The humeral component and glenoid backing have a porous coating made of, in the case of Co-Cr-Mo components, beads of the same alloy or commercially pure titanium powder, and in the case of Ti-6Al-4V components, beads or fibers of commercially pure titanium or Ti-6Al-4V alloy, or commercially pure titanium powder. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. This generic type of device is designed to achieve biological fixation to bone without the use of bone cement.

Special Controls
