Article Synopsis
- The study focused on evaluating the effectiveness of an arthroscopic bone block procedure using xenograft, in addition to Bankart repair and subscapularis augmentation, for treating recurrent anterior shoulder instability in contact athletes.
- Among the 16 athletes analyzed, none experienced new dislocations post-surgery, and there was a significant improvement in functional scores after treatment.
- The glenoid bone surface area also improved significantly, indicating successful bone integration, and all participants returned to their pre-injury levels of sport activity.
Background: Unexpected positive cultures (UPCs) are frequently observed in primary shoulder arthroplasty, and its clinical significance has not yet been well defined. This study aimed to evaluate the UPCs in humeral head in primary shoulder replacement and to understand if UPCs increase in patients with risk factors for contamination (previous surgery or infiltrations).
Methods: Patients undergoing total shoulder replacement were enrolled in this prospective observational study.
Article Synopsis
- The study aimed to assess how a software update affected measurements of glenoid inclination, version, and humeral head subluxation using a 3D planning program for shoulder surgeries.
- The analysis involved 76 CT scans from patients who had shoulder replacements, comparing results from the 2018 version of the software to the updated 2020 version.
- The results showed a significant change in glenoid inclination measurements after the update, suggesting surgeons need to critically evaluate data from automated software due to its potential variability.
Background: Shoulder arthroplasty is a successful procedure to treat degenerative and traumatic diseases of the glenohumeral joint. Periprosthetic infection represents an infrequent but dreaded complication (2%-4%). Application of intrawound vancomycin powder seems to reduce periprosthetic infections, but limited information is available on its efficiency in shoulder arthroplasty.

Clinical and radiographic outcomes were compared with the same RTSA for PHFs without a calcar fragment at a minimum of five-year follow-up.
Methods: A retrospective analysis was performed on acute PHFs "with a medial calcar fragment" (group A) and "without a calcar fragment" (group B) treated with a RTSA and cementless metaphyseal stem fixation.
