Anika Therapeutics commenced full launch of the WristMotion® Total Wrist Arthroplasty (TWA) System. The system's novel design maximizes carpal stability and enables rotational freedom, including the “dart thrower’s” motion.
WristMotion TWA is a modular joint preservation system that replaces both the radial and carpal sides of the wrist joint for patients suffering from rheumatoid arthritis, osteoarthritis or post-traumatic arthritis. The system incorporates Anika’s proven fixation technology in the central carpal taper post design, also used in the WristMotion Hemiarthroplasty System, which has been in clinical use since 2015, with over 2,600 cases performed to date.
WristMotion also utilizes Anika’s dual curvature design feature in the carpal implant combined with the dorsal flange (or hood) which allows for greater range of extension due to the increased implant surface area. Preclinical robotic testing has demonstrated that the combination of these features provides improved range of motion and rotational freedom compared to competitive devices, consistent with Anika’s design philosophy of preserving the complex kinematics of the native joints.
WristMotion TWA and the WristMotion Hemiarthroplasty System provide surgeons with multiple treatment options for different stages and severities of wrist arthritis. Both options are available in the United States, and the WristMotion Hemiarthroplasty System was recently launched in Europe.
