Arthroscopic repair of anterior-inferior glenohumeral instability using a portal at the 5:30-o'clock position: analysis of the effects of age, fixation method, and concomitant shoulder injury on surgical outcomes.

Background: Traumatic anterior-inferior shoulder joint dislocations are common injuries among the young athletic population. The aim of this study was to assess which factors, including concomitant injury (rotator cuff tears, superior labral anterior posterior [SLAP] lesions), patient age, and fixation methods, led to redislocation after arthroscopic stabilization.

Hypothesis: There are several risk factors for the outcome after arthroscopic anterior-inferior glenohumeral stabilization.

Bactericidal properties of the concentrated artificial kidney bath solution.

This study was undertaken to investigate the ability of a 30 times concentrated dialysate fluid to support or inhibit growth of bacteria, and to evaluate its shelf life. The solution was inoculated with the following organisms in the logarithmic-growth phase: Escherichia coli, coagulase-positive Staphylococcus aureus, enteric Streptococcus sp., Pseudomonas sp.
