The Comprehensive® Shoulder Solutions’ Modular Hybrid Glenoid from Biomet is a revolutionary design for replacement of the glenoid in total shoulder arthroplasty. It provides three outer pegs and three central peg options for surgical implantation. In vitro testing of the Modular Hybrid Glenoid resulted in mean axial pull-out peak loads ranging from 209 to 303 lbf, mean inferior/superior shear ...

This edition includes ten new chapters – total elbow arthroplasty, revised shoulder arthroplasty, proximal humerus hemiarthroplasty, extra articular proximal tibial fractures, submuscularis locked plating, subtrochanteric femur fractures, ankle fractures, calcaneal fractures, tibial pilon fractures, and staged ORIF. Seventeen chapters have been rewritten by new contributing authors and leaders ...

Osteoarthritis (O.A) affects over 50 million Americans. This includes mostly O.A of the shoulder, hip, and knee. Shoulder osteoarthritis (O.A) has been demonstrated in cadaver and radiographic studies to affect up to 33% of patients over the age of 60 [1]. Patients with shoulder O.A have pain, crepitus, decreased ability to place their hand at a desired point in space and loss of motion, severe...

Reverse shoulder arthroplasty (RSA) is increasingly being used to revise anatomical total shoulder arthroplasty cases. This procedure's high complication rate has been reduced by the availability of modular shoulder systems, which allows the humeral component to be preserved during the conversion. This case report describes the revision of an anatomical shoulder implant inserted in 1998. Polyet...

Over the last decade, reverse total shoulder arthroplasty has gained significant popularity due to its ability to address difficult reconstructive shoulder problems that could not be adequately treated in the past. The concept of the reverse shoulder prosthesis was introduced in the 1970s, but the initial attempts were associated with high complication and implant failure rates. The pioneering ...

BACKGROUND The effects of tranexamic acid (TXA) in the setting of shoulder arthroplasty are unclear. The objective of this study was to examine the effects of TXA in reducing the need for blood transfusions and blood loss in patients undergoing primary total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA). METHODS We conducted a systematic review and meta-analysis o...

HYPOTHESIS We hypothesized that the malpositioning of the humeral component can preclude the long-term success of anatomical total shoulder arthroplasty. The goal of this study was to evaluate the mechanical consequences of superior and inferior malpositioning of the humeral head. MATERIALS AND METHODS A numerical musculoskeletal model of the shoulder joint allowing natural humeral head trans...
