Summary
Scapho-trapezio-trapezoid (STT) fusion effectively treats wrist instability and pain, offering good functional recovery. This study confirms its reliability for various wrist conditions, including Kienböck's disease and joint arthritis.
Area of Science:
- Orthopedic Surgery
- Hand and Wrist Surgery
- Musculoskeletal Research
Background:
- Scapho-trapezio-trapezoid (STT) fusion stabilizes the wrist's radial column.
- Controversial outcomes reported in previous studies necessitate further investigation.
Purpose of the Study:
- To evaluate the efficacy of STT fusion for various wrist pathologies.
- To assess functional outcomes, pain reduction, and patient-reported disability.
Main Methods:
- Retrospective review of 111 patients undergoing STT fusion between 1992 and 1997.
- Indications included scapholunate dissociation, STT joint arthrosis, Kienböck's disease, and trapezium dislocation.
- Average follow-up of four years.
Main Results:
- Significant improvements in wrist range of motion (81% extension/flexion, 68% deviation).
- Marked pain reduction (76% non-stress, 55% stress) and improved grip strength (65%).
- Good outcomes reported via modified Mayo wrist score (average 66) and low DASH scores (average 27).
Conclusions:
- STT fusion demonstrates reliability and effectiveness in treating wrist instability and pain.
- The procedure offers reasonable functional results across diverse indications.
- This study supports STT fusion as a viable treatment option for specific wrist conditions.
