Summary
Silicone trapezium replacement surgery effectively treats arthritis of the trapezio-metacarpal joint. Patients experience significant pain relief, improved grip strength, and good function with a low complication rate.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Rheumatology
Background:
- Trapezio-metacarpal joint arthritis is prevalent, particularly in women.
- Multiple surgical interventions exist, but optimal technique remains unclear.
- This study evaluates silicone trapezium replacement outcomes.
Purpose of the Study:
- To assess the effectiveness of silicone trapezium replacement for trapezio-metacarpal joint arthritis.
- To evaluate patient satisfaction, pain, grip strength, range of motion, and disability.
- To determine the complication rate associated with this procedure.
Main Methods:
- Prospective assessment of 86 patients undergoing silicone trapezium replacement.
- Evaluation at an average of 46 months post-surgery.
- Data collected on satisfaction, pain (0-5 scale), grip strength, range of motion, complications, and DASH scores.
Main Results:
- 92% patient satisfaction reported.
- Significant pain reduction from 4.2 to 0.6.
- Grip strength recovered to 72% (key) and 84% (power) of normal.
- Low complication rate (2 cases of persistent pain, one requiring revision).
- Average DASH score was 30.
Conclusions:
- Silicone trapezium replacement is an effective surgical option for trapezio-metacarpal joint arthritis.
- The procedure provides excellent pain relief, functional recovery, and strength.
- Complications are infrequent, with good long-term outcomes.
