Eccentric Reaming is Superior to Augmented Components in B2 Glenoids: a Biomechanical study.
J Shoulder Elbow Surg
January 2025
Division of Orthopaedic Surgery, The Ottawa Hospital, University of Ottawa, Ottawa, ON, Canada. Electronic address:
Introduction: Primary glenohumeral arthritis is typically associated with glenoid retroversion and posterior bone loss. Glenoid component fixation remains a weak link in the survivorship of anatomical total shoulder arthroplasty, particularly in the B2 glenoid. The aim of this study was to compare biomechanical properties of two glenoid preparation techniques in a B2 glenoid bone loss model.

Georgetown University School of Medicine, MedStar Georgetown University Hospital, Washington, D.C, USA. Electronic address:
Introduction: As the number of revision total knee arthroplasties (rTKA) continues to rise, there is increasing interest in the use of contemporary rotating hinge prostheses. These devices often incorporate porous cones to fill bone defects and enhance long-term fixation. This study evaluated the clinical and functional outcomes and survivorship in rTKA patients utilizing a rotating hinge prosthesis with flexible titanium (FT) cones, porous tantalum (PT) cones, or no cones.

Cell wall extensibility is a key biophysical characteristic that defines the rate of plant cell growth. It depends on the wall structure and is controlled by numerous proteins that cut and/or (re)form links between the wall constituents. Cell wall extensibility is currently estimated by different in vitro biomechanical tests.

Pseudotumors are defined as exuberant non-neoplastic inflammatory masses. This condition can be associated with hip and knee arthroplasty but has not been reported in Total Ankle Arthroplasty (TAA). This paper reports a pseudotumor that formed following TAA, highlighting its clinical presentation, management, and histopathology.

Shoulder and Elbow Surgery, Schulthess Clinic Zürich, 8008 Zürich, Switzerland.
: Classical reverse shoulder arthroplasty (RSA) with a high neck-shaft angle (NSA) of 155° has shown satisfactory outcomes. However, newer RSA designs aim to improve results by modifying the stem design. This study evaluates the 5-year outcomes of a stem design featuring a rectangular metadiaphyseal fixation and a 135° NSA.
