Allograft-Prosthetic Composite Reconstruction for Massive Proximal Humeral Bone Loss in Reverse Shoulder Arthroplasty.

07:00 EST 20th December 2017 | BioPortfolio

Summary of "Allograft-Prosthetic Composite Reconstruction for Massive Proximal Humeral Bone Loss in Reverse Shoulder Arthroplasty."

Reverse total shoulder arthroplasty (RTSA) performed in the setting of massive proximal humeral bone loss often requires special reconstructive techniques. Restoration of the proximal part of the humerus with an allograft provides a number of theoretical benefits, including implant support, restoration of humeral length, deltoid tensioning, and an opportunity to repair the posterior aspect of the cuff to improve strength in external rotation and repair of the subscapularis to improve stability. However, reverse allograft-prosthesis composites (APCs) are costly, are technically demanding to use, and can be compromised by progressive allograft resorption.

Medical and Biotech [MESH] Definitions

A cartilage-capped benign tumor that often appears as a stalk on the surface of bone. It is probably a developmental malformation rather than a true neoplasm and is usually found in the metaphysis of the distal femur, proximal tibia, or proximal humerus. Osteochondroma is the most common of benign bone tumors.

Adhesives used to fix prosthetic devices to bones and to cement bone to bone in difficult fractures. Synthetic resins are commonly used as cements. A mixture of monocalcium phosphate, monohydrate, alpha-tricalcium phosphate, and calcium carbonate with a sodium phosphate solution is also a useful bone paste.
