Worldwide, shoulder replacement is considered the most exciting space within the joint replacement industry, and has seen double-digit annual growth in market revenue in recent years. The procedure has been gaining intensive interest among both orthopedic surgeons and medtech manufacturers. For surgeons, shoulder replacement is expected to become a popular joint reconstruction surgery, because in a society constantly seeking out a modern lifestyle, sports-related injuries, trauma, aging, and obesity are all contributing to an increased incidence of shoulder diseases. For companies, shoulder replacement represents one of the underserved extremity markets, with several clinical unmet needs to be addressed. In the past few years, companies have utilized different kinds of strategies to capitalize on this high-margin market, such as the fine-tuning of modular systems to provide intraoperative flexibility to surgeons, aggressive medical education to expand reverse shoulder systems’ indications, and the introduction of bone-sparing stemless designs to broaden their product portfolios. This year, patient-specific instruments (PSIs), the latest technological advance in knee replacement, have been brought to the shoulder space.
The bellwether companies that have recently launched PSIs for shoulder replacement are Zimmer, Biomet, and DJO. Zimmer’s Patient Specific Instruments Shoulder system uses 3D visualization software and complements the company’s Trabecular Metal Reverse Shoulder System. Biomet’s Signature Glenoid System features a patent-pending dual trajectory, and is used in conjunction with the company’s Comprehensive shoulder system. DJO’s Match Point System employs Materialise’s SurgiCase Connect software and is designed for the company’s Reverse Shoulder Prosthesis and Turon Modular Total Shoulder System. All these systems utilize computed tomography (CT) data to create preoperative case plans for surgeons to template and prepare for their surgeries. Upon review and plan approval by the manufacturer, shoulder surgeons are provided with an ergonomically-designed drill guide tailored specifically to the patient’s glenoid anatomy…
