Summary
Shoulder replacement surgery shows over 90% success, but 14% experience complications like instability or loosening. Revision surgery is possible but technically demanding with inferior outcomes.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Reconstructive Surgery
Background:
- Shoulder arthroplasty demonstrates high success rates in early and mid-term follow-up studies, with over 90% of patients achieving good to excellent outcomes.
- Despite overall success, shoulder replacement surgery is associated with an unavoidable complication rate of approximately 14%.
Purpose of the Study:
- To identify and analyze the incidence and contributing factors of complications following shoulder arthroplasty.
- To discuss the management strategies for failed shoulder arthroplasty, including revision surgery.
Main Methods:
- Review of early and mid-range follow-up studies on shoulder arthroplasty outcomes.
- Analysis of identified complications and their relative frequencies.
- Discussion of the multifactorial etiology of complications and treatment approaches.
Main Results:
- The most frequent complications include instability, rotator cuff tear, ectopic ossification, and glenoid component loosening.
- Less common complications encompass intraoperative fracture, nerve injury, infection, and humeral component loosening.
- Successful management of complications necessitates thorough identification and analysis of multifactorial etiologies.
Conclusions:
- While shoulder arthroplasty yields high success rates, complications are a significant concern requiring careful management.
- Revision surgery for failed shoulder arthroplasty is technically challenging and associated with less favorable outcomes compared to primary procedures.
