Aseptic loosening of the glenoid component after total shoulder arthroplasty presents a considerable treatment challenge in the setting of substantial glenoid bone loss. Glenoid component explantation and bone grafting of defects have become common methods of recreating bone stock in hopes of preventing later fractures, maintaining joint kinematics, and allowing for later glenoid reimplantation...

BACKGROUND Aseptic loosening of glenoid components is a common problem associated with total shoulder arthroplasty and one cause for failure. A new cementless fluted glenoid component was developed and has shown excellent bony ingrowth in a canine model. HYPOTHESIS Clinical utilization of this cementless fluted pegged glenoid component in total shoulder arthroplasty would lower rates of radio...

Shoulder arthroplasty represents one of the fastest growing orthopaedic procedures in the USA. In comparison to hemiarthroplasty, total shoulder arthroplasty has higher patient satisfaction and lower revision rates. Aseptic glenoid loosening remains a concern for longevity of total shoulder arthroplasties. Cement fixation on the glenoid side represents the primary and only mode of fixation in t...

Background: The projected increase in revision shoulder arthroplasty has increased interest in the outcomes of theseprocedures. Glenoid component removal and conversion to a hemiarthroplasty (HA) is an option for aseptic glenoidloosening after anatomic total shoulder arthroplasty (aTSA).Methods: We identified patients who had undergone revision shoulder arthroplasty over a 15-...

Loosening of the glenoid component is a frequent cause of failure of total shoulder arthroplasty (TSA). The etiology of glenoid component loosening is multifactorial and includes aseptic osteolysis, rotator cuff insufficiency, soft tissue instability, and infection. A loose glenoid component is frequently associated with a substantial loss of glenoid bone, which necessitates additional procedur...

Abstract Background Aseptic loosening of glenoid implants is the primary revision cause in anatomic total shoulder arthroplasty (aTSA). While supported by biomechanical studies, impact bone quality, more specifically mineral density (BMD), on aseptic remains unclear. We hypothesized that lower preoperative BMD was associated with implant aTSA. Methods retrospectively included 93 patients (69 fe...

Glenohumeral osteoarthritis is the most common reason for shoulder replacement. Total shoulder arthroplasty provides reliable pain relief and restoration of function, with implant survivorship reported at 85% at 15 years. Glenoid component wear and aseptic loosening are among the most common reasons for revision. Glenoid wear characteristics have been correlated with, among other things, the de...

2 Department of Orthopaedic Surgery, Harvard Medical School, Boston, MA Revision of the glenoid component in total shoulder arthroplasty (TSA) remains an unresolved problem. Even with meticulous surgical technique, available bone stock may preclude the implantation of a new glenoid component. Multiple studies have demonstrated that patients in whom a new glenoid can be placed have improved pain...

HYPOTHESIS The success of shoulder arthroplasty surgery has been limited by a common complication: glenoid implant loosening. Eccentric loading of the glenoid due to migration of the humeral head is considered to be the major cause of glenoid loosening and is referred to as the rocking-horse phenomenon. Glenoid implant loosening may cause pain, limitation of function, and the need for complicat...
