Full Definition
Ligament reconstruction and tendon interposition is a surgical procedure for treating thumb base arthritis. The procedure involves removing the trapezium bone, reconstructing the supporting ligaments using tendon grafts, and placing tendon tissue in the space to prevent collapse. This technique maintains joint space while providing pain relief and preserving thumb mobility.
