Stryker Launches New Gamma4 Hip Fracture Nailing System

KALAMAZOO, Michigan–(BUSINESS WIRE)–Stryker (NYSE:SYK) has launched the Gamma4 System, building on the product’s 30-year legacy of continuous innovation and clinical history. The all-new Gamma System will provide surgeons with the next generation of Stryker’s intramedullary nailing system.

“Since 2004, the Gamma3 system has been the proven workhorse of our Trauma business,” said Eric Tamweber, vice president and general manager of Stryker’s Trauma business unit. “But we haven’t proven ourselves because we have a heritage; we have a heritage because we have proven ourselves. That’s why we’re excited to introduce Gamma4, an improved, modern product designed to meet our customers’ hip fracture needs.1

The Gamma4 System is indicated for the treatment of stable and unstable fractures as well as for the stabilization of bone and the correction of bone deformities in the intracapsular, trochanteric, subtrochanteric and diaphyseal regions of the femur (including osteoporotic and osteopenic bone). The system includes:

  • Precision pin: With the Precision Pin™, the beveling potential is reduced by 66% compared to a standard ∅3.2 k wire.2
  • A redefined nail design: The nail designed by SOMA features a length-dependent RoC, a shortened proximal shaft and a chamfered distal tip with a pre-inserted set screw.
  • An integrated instrumental platform: The simplified range of all Stryker nails now works off of the existing IMN Basic set.

“Our design team has spent the past decade understanding how we could improve the Gamma system based on surgeon experience and feedback,” said James Maxey, MD, orthopedic surgeon and designer surgeon for Gamma4. “Our goal when designing the Gamma4 system was to make it easier for the surgeon and better for the patient. As one of the most commonly used devices for hip fracture repair, I am confident that we have achieved our goal of reshaping the care of hip fracture patients for many years to come. »

“The Gamma4 system includes the Precision Pin™, which allows me to control lag screw placement while having instrumentation familiar to the T2 Alpha system,” said David Forsh, MD, orthopedic surgeon at Mount Sinai Hospital in New York. “The instrumentation is sleek, the nail design and geometry have been improved, and the nail facilitates ease of insertion, which is one of the biggest benefits I’ve seen firsthand in the room. ‘operation.”
