Debridement Technique for Single-Stage Revision Shoulder Arthroplasty

Area of Science:

• Orthopedic Surgery
• Infectious Disease
• Arthroplasty

Background:

• Periprosthetic joint infection (PJI) is a growing concern in revision shoulder arthroplasty.
• Treatment options for shoulder PJI are debated, including debridement, implant retention, and staged surgeries.
• Single-stage revision offers a favorable alternative by avoiding the morbidity of two-stage procedures.

Purpose of the Study:

• To describe a meticulous debridement technique for revision shoulder arthroplasty.
• To highlight the importance of thorough debridement in managing shoulder PJI.
• To emphasize the efficacy of single-stage revision with debridement.

Main Methods:

• Utilizing a previous deltopectoral incision with extensions to address draining sinuses.
• Developing subcutaneous flaps and carefully dissecting tissue planes to expose the joint.
• Performing complete capsular excision around the glenoid while protecting the axillary nerve.
• Thorough debridement of exposed bone surfaces and irrigation with antiseptic solutions.
• Obtaining multiple cultures for tailored postoperative antibiotic therapy.

Main Results:

• Meticulous debridement in single-stage revision shoulder arthroplasty is associated with a low recurrent infection rate of 5%.
• This approach aims to reduce bacterial burden and achieve stable bone-implant interfaces.
• Effective management of shoulder PJI can be achieved without the need for a second-stage surgery.

Conclusions:

• A detailed debridement technique is crucial for successful single-stage revision shoulder arthroplasty.
• This method minimizes the risk of recurrent infection, offering a viable alternative to two-stage procedures.
• All revision shoulder arthroplasties should be managed with thorough debridement due to the high incidence of unexpected positive cultures.
