Improved Clinical Outcomes After Lateralized Reverse Shoulder Arthroplasty: A Systematic Review.

Background: Lateralized reverse shoulder arthroplasty (RSA) has emerged as an attempt to improve on some of the drawbacks of conventional RSA, such as glenoid notching and decrease in ROM. Although this new design is being used in clinical practice, the evidence is mostly limited to case series and has not been systematically reviewed.

Questions/purposes: (1) How much did patient-reported outcome measures (PROMs) and ROM improve among patients who receive a lateralized RSA implant? (2) What proportion of shoulders experience complications, revision surgery, or scapular notching?

Methods: The PubMed and EMBASE databases were searched from database inception to January 31, 2020.

Cryptococcus magnus Periprosthetic Shoulder Infection: A Case Report.

Case: We present a 68-year-old diabetic man with a periprosthetic shoulder infection (PSI) by Cryptococcus magnus. The fungus was identified 4 weeks after a revision surgery for a chronic bacterial PSI. Treatment was successful with a 2-week course of intravenous liposomal amphotericin B (5 mg/kg) followed by 6 weeks of fluconazole (200 mg/d).

Benefits of radial distortion correction in arthroscopic surgery: a first experimental study on a knee model.

Background: Lens probes used in arthroscopy typically have a small diameter and wide field-of-view. This introduces strong radial distortion (RD) into the image, ultimately affecting the surgeon's hand-eye coordination. This study evaluates potential benefits of using distortion-free images in arthroscopic surgery.
