Trapeziectomy and Mini TightRope Suspensionplasty for First Carpometacarpal Joint Arthritis

First carpometacarpal (CMC) joint arthritis is a common debilitating condition affecting thumb function. Surgical management often involves trapeziectomy to alleviate pain and restore functionality. The suspensionplasty techniques maintain the trapezial height after trapeziectomy. The older techniques used the help of ligamentoplasty by taking the flexor carpi radialis or the abductor pollicis longus. A new technique of suspensionplasty where the first metacarpal is suspended to the second by means of a strong suture material (fiberwire) and tied with help of a suture button (Mini TightRope; Arthrex, Naples, FL, USA). This technique is less invasive than the previous ligamentoplasties, because there is no need to harvest another nearby tendon. The addition of Mini TightRope suspensioplasty aims to stabilize the joint, potentially improving outcomes.
