Gamma4, the newest Gamma system, offers the next generation of Stryker’s intramedullary nailing system. The company designed Gamma4 to treat hip and femur fractures and streamline procedural workflows for surgeons. It received CE mark in September 2023 and Stryker announced an expansion with an intermediate nail in January of this year.
Stryker designed Gamma4 for fractures in the intracapsular, trochanteric, subtrochanteric and shaft regions of the femur. Its features include a redefined nail design, improved workflow and integrated instrumentation.
Using a database of over 34,000 3D bone models generated from CT scans, Stryker developed the refined nail for Gamma4. It has a chamfered distal tip, a 5mm shorter proximal body compared to Gamma3 and a length-dependent radius of curvature for long nails. This enhances anatomical fit and usability, according to a news release.
Gamma4 enhances workflows with a Precision Pin for more resistance to pull out, reducing the potential for skiving. Its integrated instruments now all work on the same instrument platform, too, standardizing surgical procedures.
“The Gamma4 system represents the latest chapter of the Gamma legacy, and we are excited to expand availability to our European customers after a successful launch in the U.S.,” said Markus Ochs, vice president and general manager of Stryker’s European Trauma & Extremities division. “This latest system demonstrates our commitment to working together with our customers to understand their needs. With evolved features to the trusted Gamma system, we believe the system will help our customers rebuild patient lives.”
