Summary
This study details a surgical technique using extensor retinaculum flaps to reconstruct ligaments for chronic trapeziometacarpal joint instability. The method offers versatile repair options for both dorsal and palmar ligament injuries.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Anatomy
Context:
- Chronic instability of the trapeziometacarpal (TMC) joint often requires surgical intervention.
- Ligamentous complex injuries can lead to significant pain and functional deficits.
Purpose:
- To describe a surgical technique for correcting chronic trapeziometacarpal joint instability.
- To reconstruct the posteromedial ligamentous complex using extensor retinaculum flaps.
Summary:
- The technique involves harvesting free segments of extensor retinaculum via small dorsal incisions for superficial dorsal injuries.
- A clip through a palmar counterincision facilitates complementary palmar reconstruction.
- An extended palmar incision allows for anterior ligament repair using a pedicled retinacular flap.
Impact:
- Provides a detailed description of a reconstructive surgical technique for TMC joint instability.
- Offers potential for improved outcomes in patients suffering from trapeziometacarpal joint instability.
- Highlights the versatility of extensor retinaculum flaps in ligament reconstruction.
