Device Story

Modular shoulder prosthesis system; components include distal stem, anatomic metaphysis, and assembly screw. Assembled in OR by surgeon; mates with existing humeral heads and glenoid replacements. Distal stem and metaphysis made of Ti-6Al-4V ELI; assembly screw made of CoCrMo alloy with UHMWPE plug to prevent loosening. Single-use components; humeral stem for cemented or cementless use; glenoid component for cemented use. Provides structural replacement for diseased or damaged shoulder joints; restores function and reduces pain.

Clinical Evidence

Bench testing only.

Technological Characteristics

Modular shoulder prosthesis. Materials: Ti-6Al-4V ELI (ASTM F136) for stem/metaphysis; CoCrMo alloy (ASTM F1537) for assembly screw; UHMWPE (ASTM F648/ISO 5834-2) plug. Single-use. Cemented or cementless humeral stem; cemented glenoid component.

Indications for Use

Indicated for patients with shoulder joint disability due to rheumatoid arthritis, non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), functional deformity, humeral head fractures, or traumatic arthritis.

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).

Special Controls

*Classification.* Class II. The special controls for this device are:(1) FDA's: (i) “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Devices—Part I: Evaluation and Testing,’ ” (ii) “510(k) Sterility Review Guidance of 2/12/90 (K90-1),” (iii) “Guidance Document for Testing Orthopedic Implants with Modified Metallic Surfaces Apposing Bone or Bone Cement,” (iv) “Guidance Document for the Preparation of Premarket Notification (510(k)) Application for Orthopedic Devices,” and (v) “Guidance Document for Testing Non-articulating, ‘Mechanically Locked’ Modular Implant Components,” (2) International Organization for Standardization's (ISO): (i) ISO 5832-3:1996 “Implants for Surgery—Metallic Materials—Part 3: Wrought Titanium 6-aluminum 4-vandium Alloy,” (ii) ISO 5832-4:1996 “Implants for Surgery—Metallic Materials—Part 4: Cobalt-chromium-molybdenum casting alloy,” (iii) ISO 5832-12:1996 “Implants for Surgery—Metallic Materials—Part 12: Wrought Cobalt-chromium-molybdenum alloy,” (iv) ISO 5833:1992 “Implants for Surgery—Acrylic Resin Cements,” (v) ISO 5834-2:1998 “Implants for Surgery—Ultra-high Molecular Weight Polyethylene—Part 2: Moulded Forms,” (vi) ISO 6018:1987 “Orthopaedic Implants—General Requirements for Marking, Packaging, and Labeling,” and (vii) ISO 9001:1994 “Quality Systems—Model for Quality Assurance in Design/Development, Production, Installation, and Servicing,” and (3) American Society for Testing and Materials': (i) F 75-92 “Specification for Cast Cobalt-28 Chromium-6 Molybdenum Alloy for Surgical Implant Material,” (ii) F 648-98 “Specification for Ultra-High-Molecular-Weight Polyethylene Powder and Fabricated Form for Surgical Implants,” (iii) F 799-96 “Specification for Cobalt-28 Chromium-6 Molybdenum Alloy Forgings for Surgical Implants,” (iv) F 1044-95 “Test Method for Shear Testing of Porous Metal Coatings,” (v) F 1108-97 “Specification for Titanium-6 Aluminum-4 Vanadium Alloy Castings for Surgical Implants,” (vi) F 1147-95 “Test Method for Tension Testing of Porous Metal,” (vii) F 1378-97 “Standard Specification for Shoulder Prosthesis,” and (viii) F 1537-94 “Specification for Wrought Cobalt-28 Chromium-6 Molybdenum Alloy for Surgical Implants.”
