CMC Joint Arthritis

CMC arthroplasty with TightRope, also known as carpometacarpal suspensionplasty, is a novel procedure employed for the treatment of basal joint arthritis (thumb arthritis) found within the trapezium bone of the carpometacarpal (CMC) joint. It addresses the associated narrowing of the joint space, instability, and dislocation. The procedure involves trapezial resection to remove the diseased joint tissue and repair of the first and second metacarpal using a suspensory device or TightRope to maintain proper thumb functioning.

Trapeziectomy is a surgical procedure to treat a medical condition called “thumb base arthritis”. The procedure involves removal of a small, cube-shaped bone known as the “trapezium” at the base of the thumb joint which joins your thumb to your wrist.
