A journal article was obtained on 10-mar-2026 that reported a retrospective study from the united states.The purpose of the study was to describe a novel technique for treatment of this unique patient population along with its risk of complications and reinfection in patients undergoing staged revision shoulder arthroplasty.The study reviewed 17 patients and 18 shoulders (1 bilateral) between january 2019 and december 2023 who underwent revision for suspected periprosthetic joint infection with proximal humeral bone loss noted preoperatively or at the time of surgery.After removal of the previous implants, a cement spacer was implanted using a osteoremedies prefabricated antibiotic humeral head, a steinmann pin, and a zimmer biomet straight humeral nail, and unspecified antibiotic cement to connect the pieces together.The spacer was press-fit into the humeral canal.Second stage reimplantation was considered in cases once patients had completed at least 6 weeks of antibiotics, they had negative inflammatory labs and there was no evidence of wound erythema or drainage.The mean age at the time of spacer placement was 63.6 ± 7.4 years, with an average follow-up of 22.8 ± 16.0 months (range 4-57 months) the study had 8 males and 9 females.It was reported through a journal article that a patient underwent stage 1 revision of unknown implants of the right shoulder on an unknown date due to infection and humeral fracture.The stage 1 implants consisted of a cemented humeral nail, steinmann pin, and cement spacer head.Approximately 3 months postop, the patient was revised to a reverse total shoulder with proximal humeral replacement due to pain.No intraop complications were identified.Due diligence has been completed for this complaint; to date all available additional information has been received.
