Kalamazoo, Michigan-based Stryker designed its Gamma4 system to treat stable and unstable fractures. It also holds an indication for the stabilization of bones and the correction of bone deformities.
It covers bone deformity correction in the intracapsular, trochanteric, subtrochanteric and shaft regions of the femur. Gamma4 also treats both osteoporotic and osteopenic bone.
“Since 2004, the Gamma3 System has been the proven workhorse of our Trauma business,” said Eric Tamweber, VP and GM, Stryker’s Trauma business unit. “But we aren’t proven because we have a legacy; we have a legacy because we are proven. That’s why we’re so excited to introduce Gamma4 — an enhanced, modern product that is designed to fulfill our customers’ hip fracture needs.”
Stryker’s system features the Precision Pin to reduce the potential for skiving by 66%. It has a redefined nail design with a shortened proximal body and chamfered distal tip, plus a pre-inserted set screw. Gamma4 also offers an integrated platform on the existing IMN basic set.
Dr. James Maxey, an orthopaedic surgeon, worked as a design surgeon for Gamma4. He said the designers aimed to “make it easier” for surgeons and better for patients.
“The Gamma4 System features the Precision Pin, which allows me to control the placement of the lag screw while having familiar instrumentation to the T2 Alpha system,” said Dr. David Forsh, an orthopaedic surgeon at Mount Sinai Hospital in New York. “The instrumentation is sleek, the nail design and geometry have been enhanced, and the nail facilitates the ease of insertion, which is one of the biggest benefits I have experienced firsthand in the operating room.”
