Aequalis Humeral Head Resurfacing in Glenohumeral Arthritis at a Minimum Followup of 2 Years
Aim. To evaluate results of Aequalis humeral head resurfacing in patients with end-stage glenohumeral arthritis at a minimum followup of two years. Patients and Methods. Twenty-one consecutive patients underwent humeral head resurfacing hemiarthroplasty between 2007 and 2009. Three patients did not fulfill the inclusion criteria. 18 patients with mean age of 75.1 years (range 58-91 years) and a...
متن کاملHumeral resurfacing hemiarthroplasty with meniscal allograft in a young patient with glenohumeral osteoarthritis.
STUDY DESIGN Case report. BACKGROUND Management of glenohumeral joint osteoarthritis in young, active patients is challenging due to the significant functional limitations and progression of the disease, coupled with the limited lifespan of prosthetic implants presently in use. The purpose of this report is to present the detailed rehabilitation program and outcome of a patient who suffered a...
متن کاملBiomechanical comparison of anatomic humeral head resurfacing and hemiarthroplasty in functional glenohumeral positions.
BACKGROUND Resurfacing of the humeral head has gained interest as an alternative to traditional hemiarthroplasty because it preserves bone stock and respects the native geometry of the glenohumeral articulation. The purpose of this study was to compare the biomechanics of the intact glenohumeral joint with those following humeral head resurfacing and following hemiarthroplasty. METHODS Seven ...
متن کاملDetermination of humeral head size in anatomic shoulder replacement for glenohumeral osteoarthritis.
BACKGROUND We hypothesized that a sphere mapped to specific preserved nonarticular landmarks of the proximal humerus can accurately predict native humeral head radius of curvature (ROC) and head height (HH) in the osteoarthritic, deformed humeral head. METHODS Three consistent nonarticular landmarks were defined with a 3-dimensional sphere (and 2-dimensional circle in midcoronal plane) placed...
متن کاملDurability of partial humeral head resurfacing.
BACKGROUND Partial humeral head resurfacing arthroplasty uses a stemless device, which conserves bone and restores normal anatomy. We hypothesized that this does not offer a reasonable alternative to full resurfacing or total shoulder arthroplasty. METHODS We performed a retrospective study of 39 shoulders with focal chondral defects of the humeral head treated with partial resurfacing arthro...
