Abstract
Objective
Two-stage exchange with an antibiotic-loaded polymethylmethacrylate (PMMA) spacer is standard treatment for chronic periprosthetic joint infection of the shoulder. We present a safe and simple technique for patient-specific spacer implants.
Indication
(Chronic) periprosthetic joint infection of the shoulder.
Relative contraindications
Known allergy against components of PMMA bone cements. Inadequate compliance for two-stage exchange. Patient is unfit to undergo two-stage exchange.
Surgical technique
Hardware removal, histologic and microbiologic samples, and debridement. Preparation of targeted or calculated antibiotic-loaded PMMA. Tailoring of patient-specific spacer. Spacer implantation.
Postoperative management
Rehabilitation protocol. Antibiotic treatment. Reimplantation after successful eradication of infection.
