Summary
A 49-year-old woman with chronic glenohumeral osteomyelitis underwent a 2-stage soft-tissue shoulder interposition arthroplasty. This procedure successfully controlled pain and prevented reinfection, offering a viable alternative for high-risk patients.
Area of Science:
- Orthopaedic Surgery
- Infectious Disease
- Reconstructive Surgery
Background:
- A 49-year-old female patient presented with severe shoulder dysfunction and pain two years post-arthroscopic surgery.
- Evaluation revealed chronic glenohumeral osteomyelitis and irreparable damage to the humeral articular surface.
Observation:
- A two-stage soft-tissue shoulder interposition arthroplasty was performed to address the joint's instability and damage.
- The surgical approach aimed to rebalance the glenohumeral joint.
Findings:
- Long-term follow-up demonstrated significant functional improvement and effective pain management.
- No evidence of reinfection was observed post-procedure.
Implications:
- This interposition arthroplasty technique serves as a functional salvage option for patients with high reinfection risk or those unsuitable for prosthetic joint replacement.
- The study highlights the potential of this approach in managing complex shoulder osteomyelitis cases.
