Anika Launches the WristMotion® Total Wrist Arthroplasty System at the American Society for Surgery of the Hand Annual Meeting
“We are excited to offer surgeons and patients multiple options to treat wrist arthritis with our WristMotion family of products,” said
Designed in collaboration with Dr.
The WristMotion TWA System 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 date1. The WristMotion TWA System 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 area2. 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 joints2.
“Historically, patients suffering with advanced wrist pain caused by arthritis or trauma were treated with older versions of total wrist arthroplasty systems or with wrist fusions. Existing total wrist arthroplasty implants on the market today may enable some wrist motion but are at higher risk of carpal loosening. Alternatively, a wrist fusion may severely limit a patient’s ability to move and use their wrist. Neither option restores wrist function, and that’s the core reason the WristMotion TWA System is a significant step forward for surgeons and patients,” said
The WristMotion TWA System has been available to select customers during a limited market release starting after the first case was performed by
“The WristMotion TWA System’s proprietary central threaded taper post helps ensure secure carpal fixation. This secure carpal fixation, coupled with the ability to adjust the height and tension of the wrist joint on the radial side rather than carpal, strengthens the implant’s stability and also preserves the natural center of rotation,” said
The WristMotion TWA System, along with the WristMotion Hemiarthroplasty System, provide surgeons with multiple treatment options for different stages and severities of wrist arthritis. Both options are available in
