OsseoFit® Stemless Shoulder humeral components have a porous surface and are indicated for uncemented biological fixation applications Compatible Glenoid components are intended to be implanted with bone cement. The porous posts may be inserted without bone cement. Compatible Convertible Glenoid Baseplate components are intended for cementless applications with the addition of screw fixation. ## Device Story OsseoFit Stemless Shoulder System is an anatomic total shoulder prosthesis; includes stemless humeral anchor with porous surface for biological fixation; used with compatible humeral heads and glenoid components. Subject submission adds modular 'Universal' surgical broaches to facilitate humeral anchor implantation. Broaches consist of 2-piece construction (proximal and distal bodies) allowing intra-operative flexibility between Inlay and Onlay configurations; assembled broaches replicate geometry of previously cleared monoblock broaches. Used by orthopedic surgeons in clinical settings for bone preparation during shoulder arthroplasty. System provides structural support for joint replacement; porous surface promotes biological fixation. ## Clinical Evidence No clinical data provided. Substantial equivalence supported by non-clinical bench testing of the new Universal Broaches, confirming they meet acceptance criteria for structural integrity and extraction capability during surgical use. ## Technological Characteristics System includes stemless humeral anchor with OsseoTi porous technology. Universal Broaches are 2-piece modular instruments (proximal/distal bodies) for bone preparation. Materials and sterilization methods are identical to the predicate. Devices are non-sterile, reusable instruments. ## Regulatory 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.
