The SMR Shoulder System is intended for partial or total, primary or revision shoulder joint replacement.

The SMR Anatomic Shoulder System is indicated for partial or total, primary or revision shoulder joint replacement in patients suffering from disability due to:

• non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis;
• inflammatory degenerative joint disease such as rheumatoid arthritis;
• treatment of acute fractures of the humeral head that cannot be treated with other fracture fixation methods;
• revision of a failed primary implant; in case of SMR Short Stems only if sufficient bone stock remains);
• cuff tear arthropathy (CTA Heads only);
• glenoid arthrosis without excessive glenoid bone loss: A1, A2 and B1 according to Walch classification (SMR TT Hybrid Glenoid only).

The SMR Reverse Shoulder System is indicated for primary, fracture or revision total shoulder replacement in a grossly rotator cuff deficient joint with severe arthropathy (disabled shoulder). The patient's joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device.

The SMR TT Hybrid Glenoid Reverse Baseplate must not be used in cases of excessive glenoid bone loss and/or when bone graft is needed.

The Modular SMR Shoulder System allows the assembly of components in various humeral and glenoid constructs. The constructs are intended for cemented and uncemented use as specified in the following table.

In the Anatomic shoulder the humeral construct consists of the humeral stem, the humeral body, the adaptor taper and the humeral head. In the Reverse shoulder the humeral construct consists of the humeral stem, the reverse humeral body and the reverse liner. On the humeral side the fixation of the humeral stem determines if the construct is cemented or uncemented.

The Anatomic glenoid construct consists of an all polyethylene glenoid, a polyethylene glenoid with metal peg or a metal back assembled with a liner; the Reverse glenoid consists of a metal back/connector/glenosphere construct or of a peg/baseplate/glenosphere construct.

On the glenoid side, the fixation of all polyethylene glenoid, the polyethylene glenoid with metal peg or the metal back determines if the construct is cemented or uncemented.

The PRIMA Glenoid System is indicated for primary, fracture or revision total shoulder replacement in a grossly rotator cuff deficient joint with severe arthropathy (disabled shoulder). The patient's joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device.

The PRIMA Glenoid System components are intended for uncemented use with the addition of screw fixation.

The PRIMA Humeral System is intended for partial or total, primary or revision, shoulder joint replacement in skeletally mature patients. The patient's joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device. The PRIMA Short Stem and PRIMA Short Stem Plus are intended for use in cementless and cemented applications, at the discretion of the surgeon.

The PRIMA Anatomic implant is indicated for partial or total, primary or revision shoulder joint replacement, in patients suffering from pain and disability due to:

• Non-inflammatory degenerative joint disease (i.e. osteoarthritis),
• Inflammatory arthritis of the glenohumeral join including rheumatoid arthritis,
• Avascular necrosis of the humeral head,
• Traumatic/post-traumatic arthritis,
• Fractures of the humeral head where adequate fixation can be achieved and adequate bone stock remains,
• Post-fracture deformity with intact rotator cuff, where adequate fixation can be achieved and adequate bone stock remains,
• Cuff tear arthropathy (CTA Heads only).

The PRIMA Reverse implant is indicated for primary reverse total shoulder replacement or for revision when converting an anatomic PRIMA arthroplasty to a reverse total shoulder arthroplasty (i.e. in case of cuff tear arthropathy or in a grossly rotator cuff deficiency joint with severe arthropathy).

Revision surgery with retention of the PRIMA Short Stem and PRIMA Short Stem Plus are intended as conversion surgery from anatomic to reverse, where the stem is stable, well positioned and tissue integrated. Other revisions of the humeral prosthesis part should be treated with traditional shoulder prostheses.

The PRIMA reverse implant is indicated for patients suffering from pain and disability due to:

• Rotator cuff tear arthropathy,
• Osteoarthritis with rotator cuff tear,
• Rheumatoid arthritis with rotator cuff tear,
• Massive irreparable rotator cuff tear,
• Avascular necrosis of the humeral head,
• Correction of functional deformity, where adequate fixation can be achieved and adequate bone stock remains,
• Fractures of the humeral head where adequate fixation can be achieved and adequate bone stock remains.

The subject devices consist of a line extension of the SMR Shoulder System and the PRIMA Shoulder System. The new devices introduced with this 510(k) are SMR and PRIMA Glenospheres with diam. 40 and 44mm made of Vitamin E crosslinked UHMWPE (LimaVit) and corresponding CoCrMo humeral liners.

The PRIMA Humeral System consists of the following single use components:

• Anatomic configuration:
  • Stem
  • adaptor for humeral heads.
• Reverse configuration:
  • stem
  • reverse tray and polyethylene reverse insert, or
  • metallic reverse insert.
