System components include humeral stems (cemented/uncemented), Bigliani/Flatow (B/F) humeral heads, B/F glenoids, Trabecular Metal glenoids, and a new AS B/F Adaptor. The adaptor serves as an interface, featuring two taper geometries: one connecting to Anatomical Shoulder humeral stems and the other to B/F humeral heads. This allows surgeons to combine components from the Anatomical Shoulder and Bigliani/Flatow systems. The device is implanted by orthopedic surgeons in a clinical/hospital setting. By restoring joint articulation, the system aims to alleviate pain and improve function in patients with advanced shoulder joint destruction. The adaptor's taper interfaces are designed to match the geometry of predicate components, ensuring secure assembly. ## Clinical Evidence No clinical data provided. Substantial equivalence is supported by non-clinical bench testing, including evaluation of loading conditions, fatigue analysis, fretting corrosion, and assembly strength tests. ## Technological Characteristics Modular shoulder prosthesis. Materials: Protasul-1 (Co-Cr-Mo), Protasul-100 (titanium alloy), Zimaloy (Co-Cr-Mo), UHMWPE, and Trabecular Metal. Features dual-taper adaptor for component compatibility. Cemented or cementless fixation. Mechanical assembly via taper interfaces. ## Regulatory Identification A shoulder joint metal/polymer non-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder joint. The device limits minimally (less than normal anatomic constraints) translation in one or more planes. It has no linkage across-the-joint. This generic type of device includes prostheses that have a humeral 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.

12/10/2002 | -- {1}------------------------------------------------ ### Device Description: The Anatomical Shoulder (AS) Combined System consists of the following: - AS Humeral Stem (cemented or . uncemented) - AS Fracture Humeral Stem � - Bigliani/Flatow Head . - Bigliani/Flatow Gleniod . - Trabecular Metal (TM) Glenoid . - AS Bigliani/Flatow (AS B/F) Adaptor . The AS B/F Adaptor is a new product designed to be used with the humeral stems of the Anatomical Shoulder System and Anatomical Shoulder Fracture System and with any humeral head of the Bigliani/Flatow (BF) System in a conventional hemi or total shoulder arthroplasty procedure. The B/F humeral heads are used with existing UHMWPE B/F glenoids and TM glenoids manufactured from Trabecular Metal and UHMWPE. AS cemented humeral stems are manufactured from Protasul -1 (Co-Cr-Mo); the uncemented and fracture stems from Protasul-100 (titanium alloy). The B/F heads are manufactured from Zimaloy® (Co-Cr-Mo). Collectively, these components are identified as the Anatomical Shoulder Combined System. The Adaptor features two taper interfaces, one connecting to the Anatomical Shoulder humeral stems and the other connecting to the Bigliani/Flatow humeral heads. The proximal taper of the adaptor (connecting to the Bigliani/Flatow heads) is identical to the male taper geometry from the predicate Bigliani/Flatow humeral stems. The distal taper of the adaptor (connecting to the Anatomical Shoulder humeral stem) is a male oval taper, identical to the oval taper of the predicate Anatomical Shoulder Ball-Taper component. Both the AS B/F Adaptor and the predicate AS Ball-Taper component are manufactured from Protasul-100, a forged titanium alloy. Advanced destruction of the shoulder joint resulting from: - Omarthrosis. ● - Rheumatoid arthritis .

When used with the following humeral stems the Anatomical Shoulder Combined System is intended for cemented use: - Anatomical Shoulder Standard Cemented t Humeral Stem. - Anatomical Shoulder Revision Stem. . When used with the following humeral stem the Anatomical Shoulder Combined System is intended for cementless use: - Anatomical Shoulder Standard Uncemented . Stem. When used with the following humeral stems the Anatomical Shoulder Combined System is intended for cemented or cementless use: - Anatomical Shoulder Fracture Stem. . - Anatomical Shoulder Fracture Long Stem. . When used with the following glenoids the Anatomical Shoulder Combined System is intended for cemented use: - Bigliani/Flatow Glenoid (pegged and keeled). . - Trabecular Metal Glenoid. . Comparison to Predicate Device: The proposed Anatomical Shoulder Combined System consists of some of the same devices as the referenced predicates, including: Anatomical Shoulder humeral stems, Bigliani/Flatow humeral heads and glenoids, and the Trabecular Metal glenoid. Additionally, the new AS B/F component has identical proximal taper geometry to that of the predicate Bigliani/Flatow humeral stem and identical distal taper geometry to that of the predicate Anatomical Shoulder Ball-Taper component. Collectively, the proposed system has the same intended use, has similar performance {3}------------------------------------------------ characteristics, is manufactured from similar materials using similar processes, and is similar in design to the predicate devices. Performance Data (Nonclinical and/or Clinical): Non-Clinical Performance and Conclusions: The results of non-clinical (lab) performance testing and/or analyses demonstrate that the devices are safe and effective and substantially equivalent to the predicate devices. Performance testing and/or analyses included: Evaluation of Loading Conditions, Fatigue Analysis, Fretting Corrosion, Assembly Strength Test. Clinical Performance and Conclusions: Clinical data and conclusions were not needed for this device. {4}------------------------------------------------ Image /page/4/Picture/1 description: The image shows the seal of the Department of Health & Human Services USA.
