New KinematX Total Wrist Arthroplasty from Extremity Medical

Extremity Medical announced the first surgical case using the KinematX™ Total Wrist device.

KinematX is the only midcarpal implant designed to mimic the natural range of motion in patients with wrist arthritis and other degenerative conditions. The system was cleared for U.S. marketing by FDA in 2020.

The new KinematX Total Wrist is similar in design to the KinematX Hemiarthroplasty implant, a midcarpal-based implant that has been available outside of the U.S. since 2011. Clinical data on the original partial wrist implant indicate improved wrist range of motion, grip strength and patient-reported outcome scores.

The design of KinematX was based on a new research approach to developing, identifying, tracking and measuring the precise motions of the eight bones in the human wrist.

“KinematX is the only wrist replacement designed and engineered to mimic the motion of the human wrist for a durable and natural range of motion that allows normal acitivies,” said Matt Lyons, CEO of Extremity Medical. “The challenge of addressing mechanical properties of the wrist is something few medical device companies have tackled and – until now – none have mastered.”
