Intended Use
The WMT Modular Shoulder is indicated for use in shoulder arthroplasty for reduction or relief of pain and/or improved shoulder function in skeletally mature patients with sufficient and satisfactory bone stock to support the prosthesis with the following conditions: Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis; Rheumatoid arthritis or post-traumatic arthritis; Revision where other devices or treatments have failed; Correction of functional deformity; Treatment of acute fracture of the humeral head unmanageable using other treatment methods; and Cuff tear arthroplasty. Hemi-shoulder replacement is also indicated for: Ununited humeral head fractures; and Avascular necrosis of the humeral head. The humeral stem may be implanted by press-fit or cement fixation.
Device Story
Modular shoulder prosthesis system comprising humeral stems, humeral heads, and glenoid implants. Designed for shoulder arthroplasty to address degenerative joint disease, fractures, and revision cases. Components allow for press-fit or cemented fixation of humeral stems. System provides multiple stem sizes and head radii/heights to accommodate patient anatomy. Used by orthopedic surgeons in clinical settings to restore joint function and reduce pain. Device functions as a mechanical replacement for the shoulder joint; no electronic or software components involved.
Clinical Evidence
Bench testing only.
Technological Characteristics
Modular shoulder prosthesis system. Components: humeral stem, humeral head, glenoid implants. Materials: metal/polymer. Fixation: press-fit or cemented. Humeral stems available in various lengths (110mm-225mm) and diameters (6mm-16mm). Humeral heads available in 5 radii (20-28mm) and 3 heights. Mechanical device; no energy source, connectivity, or software.
Indications for Use
Indicated for skeletally mature patients requiring shoulder arthroplasty for pain relief or improved function due to osteoarthritis, avascular necrosis, rheumatoid arthritis, post-traumatic arthritis, functional deformity, acute humeral head fractures, cuff tear arthroplasty, or revision of failed treatments. Hemi-shoulder replacement indicated for ununited humeral head fractures and avascular necrosis.
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).
