A major cause of failure in shoulder surgery is shoulder infections. Here’s a Cutibacterium case showing a shoulder periprosthetic infected.
I. The authors of The POSI Study: Gender differences among 94 cases postoperative shoulder injury infection: Results from a multicenter retrospective study over 7 years that examined the characteristics of patients with postoperative shoulder injuries. Two positive cultures, more than one of the same microorganisms, or a clear clinical infection with only one positive culture were considered to be a confirmed shoulder infection.
The median patient age at index operation was 59 years, with a range of 22-91. Most patients were men (74%). The most common index procedure was arthroplasty. Followed by fracture fixation and arthroscopic surgeries were the next two.
The median time from index surgery to first positive sample was five months. It ranged from minimum 6 days up to maximum 27 year. For Cutibacterium infections, the median time between diagnosis and index surgery was 8.6 months. This compares to 3.9 months for other organisms.
64 Cutibacterium species have been identified in 64 patients (68%), and 59 of these were Cutibacterium Acnes (63%). 86% of…
