Anatomic total shoulder arthroplasty for posteriorly eccentric and concentric osteoarthritis: a comparison at a minimum 5-year follow-up.

Background: In patients with glenohumeral osteoarthritis and posteriorly eccentric wear patterns, the early to midterm results of total shoulder arthroplasty (TSA) using conservative glenoid reaming with no attempt at version correction have been favorable at early follow-up. The purpose of this study is to compare the clinical and radiographic outcomes of TSA using this technique for patients with and without eccentric wear patterns at a minimum 5-year follow-up.

Methods: Patients who underwent TSA with minimum 5-year follow-up were identified from an institutional registry.

Anatomic Total Shoulder: Predictors of Excellent Outcomes at Five Years after Arthroplasty.

Purpose: The objectives of this study were to: report minimum 5-year outcomes in patients undergoing TSA and determine characteristics predictive of patients achieving an excellent functional outcome.

Methods: Pre-operative demographic variables and Simple Shoulder Test (SST) scores were obtained pre-operatively and at a minimum of five years after surgery. A final SST ≥ 10 and percentage of maximal possible improvement (% MPI) of ≥ 66.

Managing rotator cuff tear arthropathy: a role for cuff tear arthropathy hemiarthroplasty as well as reverse total shoulder arthroplasty.

Background: Disabling cuff tear arthropathy (CTA) is commonly managed with reverse shoulder arthroplasty (RSA). However, for patients with CTA having preserved active elevation, cuff tear arthropathy hemiarthroplasty (CTAH) may offer a cost-effective alternative that avoids the complications unique to RSA. We sought to determine the characteristics and outcomes of a series of patients with CTA managed with these procedures.

Routine Indwelling Urinary Catheterization Is Not Necessary During Total Hip Arthroplasty Performed Under Spinal Anesthesia.

Background: Perioperative indwelling urinary catheterization remains common in patients undergoing total hip arthroplasty. This study sought to examine the effect of routine catheterization following total hip arthroplasty performed under spinal anesthesia on urinary complications.

Methods: A total of 991 consecutive patients who underwent primary total hip arthroplasty under spinal anesthesia over a 4-year period were retrospectively reviewed.

Enhancing Vascularization through the Controlled Release of Platelet-Derived Growth Factor-BB.

Using delivery systems to control the in vivo release of growth factors (GFs) for tissue engineering applications is extremely desirable as the clinical use of GFs is limited by their fast in vivo turnover. Hence, the development of effective platforms that are able to finely control the release of GFs in vivo remains a challenge. Herein, we investigated the ability of multiscale microspheres, composed by a nanostructured silicon multistage vector (MSV) core and a poly(dl-lactide-co-glycolide) acid (PLGA) forming outer shell (PLGA-MSV), to release functional platelet-derived growth factor-BB (PDGF-BB) to induce in vivo localized neovascularization.
