Risk Factors for Glenoid Bone Loss in the Setting of Posterior Glenohumeral Instability.

Background: Posterior instability has been reported to account for up to 24% of cases of shoulder instability in certain active populations. However, there is a paucity of data available regarding the risk factors associated with posterior glenoid bone loss.

Purpose: To characterize the epidemiology of, and risk factors associated with, glenoid bone loss within a cohort of patients who underwent primary arthroscopic shoulder stabilization for isolated posterior-type glenohumeral instability.

Prevalence and Risk Factors of Glenoid Bone Loss in Combined Shoulder Instability in Young, Active-Duty Military Patients.

Background: US military servicemembers experience higher rates of posterior and combined-type instability as compared with their nonmilitary peers.

Purpose: (1) To determine the prevalence of glenoid bone loss (GBL) in young, active-duty military patients with combined-type shoulder instability who underwent operative shoulder stabilization; (2) to evaluate whether GBL is associated with differences in postoperative outcomes; and (3) to identify factors associated with larger defects.

Study Design: Case series; Level of evidence, 4.

Comparative Outcomes for the Treatment of Articular Cartilage Lesions in the Ankle With a DeNovo NT Natural Tissue Graft: Open Versus Arthroscopic Treatment.

Background: The treatment of osteochondral lesions of the talus (OLTs) with a juvenile cartilage allograft is a relatively new procedure. Although other treatment options exist for large OLTs, the potential advantage of a particulated juvenile allograft is the ability to perform the procedure arthroscopically or through a minimal approach. No previous studies have looked at the results of an arthroscopic approach, nor have any compared an arthroscopic technique with an open approach.

A reason to renovate: The association between hospital age of plant and value-based purchasing performance.

Background/purpose: Value-based purchasing (VBP) is increasing in influence in the health care industry; however, questions remain regarding the structural factors associated with improved performance. This study evaluates the association between age of hospital infrastructure and VBP outcomes.

Methodology: Data on 1,911 hospitals from three sources (the American Hospital Association Annual Survey Database, the American Hospital Association DataViewer Financial Module, and the Centers for Medicare & Medicaid Services Hospital VBP Total Performance Scores data set) were evaluated.
