Reverse rhino sign as a radiological sign of low-grade infected reverse shoulder arthroplasty.

Introduction: Low-grade infections following shoulder surgery are difficult to diagnose. Recently, curved-shaped bony spurs, further mentioned "reverse rhino signs" because of its shape, growing inferior on the glenoid were noticed on X-rays of patients with a reverse shoulder arthroplasty (RSA) and a Cutibacterium acnes (C. acnes) infection.

Better diagnostic value of tissue cultures obtained during mini-open and arthroscopic procedures compared with sterile punctures to identify periprosthetic shoulder infections: a retrospective cohort study.

Background: This study aimed to determine the sensitivity and specificity of sterile shoulder needle aspiration and cultures obtained during arthroscopic and mini-open procedures for detecting periprosthetic shoulder infections using tissue cultures from revision surgery as the gold standard.

Methods: All shoulder arthroplasty patients who underwent a synovial fluid puncture between August 2012 and February 2018 were selected. In addition, arthroplasty patients with cultures obtained during arthroscopic or mini-open procedures between May 2014 and May 2021 were selected.

Pre- and peroperative diagnosis of infections in shoulder surgery: A systematic review.

Background: is the most commonly detected pathogen during shoulder surgery. Lack of typical infection signs make infections difficult to diagnose. This systematic review aims to determine which pre- and peroperative diagnostic tools are most reliable to identify infections after shoulder surgery.

Cutibacterium acnes infections in revision surgery for persistent shoulder complaints: a retrospective cohort study.

Introduction: Low-grade Cutibacterium acnes (C. acnes) infections after shoulder surgery usually result in unexplained complaints. The absence of clinical signs of infection makes the incidence unclear and underreported.

The presence of Cutibacterium acnes on the skin of the shoulder after the use of benzoyl peroxide: a placebo-controlled, double-blinded, randomized trial.

Hypothesis And Background: We hypothesized that benzoyl peroxide (BPO) would reduce the presence of Cutibacterium acnes on the skin of the shoulder by 50% compared with placebo. Infections after shoulder surgery are most commonly caused by C acnes. Current prophylactic methods do not effectively reduce the bacterial load of this bacterium.
