Intended Use

The Anatomical Shoulder™ Fracture System is intended for use in prosthetic replacement of the proximal humerus and the glenoid articular surface of the scapula during total-, hemi- and fracture shoulder arthroplasty in treatment of the following: Complex 3 and 4 part fractures of the proximal humerus with subluxation of the head fragment; Complex 3 and 4 part fractures of the proximal humerus with loosening of the spongiosa in the head fragment; Complex 3 and 4 part fractures of the proximal humerus with additional cross split of the head fragment; Fracture instability after osteosynthesis of 3 and 4 fragments of the proximal humerus; Posttraumatic necrosis of the humeral head; Posttraumatic arthrosis after humeral head fracture. The Anatomical Shoulder Fracture stem is intended for cemented or cementless use.

Device Story

Prosthetic system for proximal humerus and glenoid replacement; treats complex fractures and post-traumatic conditions. Components include stem, baseplate, screw, and head. Features spikes on proximal stem and baseplate for tuberosity anchoring; includes suture holes for fixation. Stem compatible with Anatomical Shoulder System glenoid components and Inverse/Reverse humeral cup for conversion surgery in cases of irreparable rotator cuff. Used in orthopedic surgery; implanted by surgeons. Provides stable fixation of humeral tuberosities; restores joint function; enables conversion to reverse arthroplasty if needed.

Clinical Evidence

Bench testing only. Performance testing confirmed all components meet or exceed predetermined performance criteria for intended use.

Technological Characteristics

Modular shoulder prosthesis consisting of stem, baseplate, screw, and head. Features include proximal spikes for tuberosity anchoring and integrated suture holes. Designed for cemented or cementless fixation. Materials and manufacturing methods consistent with predicate shoulder arthroplasty systems.

Indications for Use

Indicated for patients requiring total, hemi, or fracture shoulder arthroplasty due to complex 3 or 4-part proximal humerus fractures (with subluxation, spongiosa loosening, or cross-split), fracture instability post-osteosynthesis, post-traumatic humeral head necrosis, or post-traumatic arthrosis.

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).

consists of four components, a stem, baseplate. screw and head. The Anatomical Shoulder Fracture System baseplate offers right and left side-specific versions in order to appropriately match the original shoulder anatomy with respect to right and left humeral anatomy.

The Anatomical Shoulder Fracture System head is also designed to articulate with the glenoid components of the Anatomical Shoulder System (K030259). The Anatomical Shoulder Fracture System stem is also designed to accept the Anatomical Shoulder Inverse/Reverse humeral cup (K053274) for conversion from hemi- or total shoulder arthroplasty to an inverse/reverse shoulder arthroplasty in situations when the rotator cuff is irreparable and the patient is experiencing severe instability of the shoulder joint.

The Anatomical Shoulder Fracture System stem is comparable in shape and size to stems traditionally used for hemi- and total shoulder arthroplasty. The Anatomical Shoulder Fracture System stem, however, has two features which distinguish it as a stem designed for treatment of proximal humeral fractures. The proximal surface of the humeral stem and much of the surface of the baseplate offer spikes which assist in the stable anchoring of the humeral tuberosities to the stem and allow for primary stability of the tuberosities. The Anatomical Shoulder Fracture System stem and baseplate also offer several suture holes to allow initial stable fixation of the humeral tuberosities with sutures.

The Anatomical Shoulder Fracture System is substantially equivalent to the predicate devices in regards to its intended use, design, size ranges, materials and manufacturing methods.

Non-Clinical Performance and Conclusions: Performance testing indicates that all components meet or exceed predetermined performance criteria for their intended use.
