Summary
This study demonstrates that ligament reconstruction effectively restores stability and mobility to the trapeziometacarpal (first carpometacarpal or CMC-I) joint. The procedure offers good to very good outcomes for patients suffering from chronic CMC-I joint instability.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Reconstructive Surgery
Background:
- The trapeziometacarpal (CMC-I) joint is crucial for thumb function.
- Instability of the CMC-I joint can result from trauma, congenital conditions, or osteoarthritis, leading to pain and functional limitations.
Purpose of the Study:
- To evaluate the efficacy of transosseous ligament reconstruction for restoring stability and preserving mobility in the CMC-I joint.
- To assess the outcomes of this surgical technique in patients with chronic CMC-I joint instability.
Main Methods:
- A radiopalmar approach was utilized for CMC-I joint access and reduction.
- Transosseous ligament reconstruction was performed using a distally pedicled tendon strip from the abductor pollicis longus muscle.
- Postoperative management involved splint immobilization for 5 weeks.
Main Results:
- The ligament reconstruction procedure demonstrated good to very good outcomes in the majority of patients.
- One out of 24 patients experienced a rupture of the ligament reconstruction.
- The technique successfully relieved pain and restored stability while maintaining functional range of motion.
Conclusions:
- Ligament reconstruction is an effective treatment for chronic CMC-I joint instability.
- This surgical approach restores thumb joint stability and function, improving patient quality of life.
