Summary
Scaphotrapeziotrapezoid fusion is a viable wrist surgery option, offering good range of motion and strength. Careful technique minimizes complications like nonunion, making it suitable for active individuals with wrist issues.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Wrist Biomechanics
Background:
- Scaphotrapeziotrapezoid (STT) arthritis is a common cause of wrist pain.
- Surgical intervention is often required for significant STT joint pathology.
Purpose of the Study:
- To evaluate the long-term outcomes of 800 scaphotrapeziotrapezoid fusions.
- To assess functional recovery and complication rates following STT fusion surgery.
Main Methods:
- Retrospective review of 800 STT fusion cases over 27 years.
- Postoperative assessment of range of motion, grip/pinch strength, pain, return to work, arthritis development, and complications.
Main Results:
- Achieved 70-80% of contralateral range of motion and 69-89% of strength.
- 88% of patients returned to previous employment.
- Low incidence of post-fusion arthritis (1.8%) and overall complication rate of 13.4%.
Conclusions:
- Scaphotrapeziotrapezoid fusion is a successful treatment for wrist pathology, particularly in young, active patients.
- Meticulous surgical technique is crucial for minimizing complications such as nonunion.
