Summary
Posterior instability surgery has high rates of recurrence, revision, and complications. Many patients experience persistent pain and restricted external rotation, indicating unsatisfactory outcomes.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Shoulder Instability
Background:
- Posterior shoulder instability presents unique surgical challenges.
- Assessing outcomes after surgical repair is crucial for patient management.
Purpose of the Study:
- To evaluate the outcomes of soft-tissue posterior instability surgery.
- To identify challenges and complications associated with the procedure.
Main Methods:
- Retrospective review of 19 patients undergoing posterior shoulder instability surgery (2000-2015).
- Analysis of recurrence, revision, pain, subjective improvement, complications, and range of motion.
- Statistical comparison using Fisher's exact and Mann-Whitney U tests.
Main Results:
- High rates of recurrent subluxation (32%) and persistent pain (58%).
- Significant need for revision surgery (53%) and complications (37%).
- Postoperative external rotation was restricted in 64% of patients.
Conclusions:
- Soft-tissue posterior instability surgery is associated with high rates of poor outcomes.
- Patients should be counseled regarding the risks of persistent pain, instability, and limited range of motion.
- Further research is needed to improve surgical techniques and patient results.
