Arthroscopic trapeziometacarpal arthroplasty

Advanced basal joint arthritis that has failed conservative treatment has traditionally been treated with some type of procedure that encompasses complete trapezial excision. An arthroscopic technique entailing only minimal trapezial debridement coupled with insertion of a synthetic interposition material is described. This provides the implicit benefits of a minimally invasive procedure, with less pain and faster recovery, along with the great advantage of trapezium preservation. The surgical technique is described along with a preliminary clinical series support-ing its use.
