Smith & Nephew Releases New Hip Revision System
Having reported a solid financial third quarter, Smith & Nephew plc has released the new Redapt revision femoral system. The system is part of a plan to bring personalized medicine to the revision hip market—the system allows surgeons to recreate a patient’s unique functionality while addressing issues such as poor bone quality and proximal/distal mismatch.
“With other revision systems, the main goal is simply to provide a patient with a stable joint,” said Reid Brown, M.D., of Louisville Bone and Joint Specialists in Kentucky. “Redapt changes these outcome expectations to include the type of functional standards typically associated with primary total hip replacements. And, it does so with streamlined, reproducible instrumentation and a shorter learning curve.”
The Redapt system works by allowing the surgeon to prepare the femoral canal and complete full hip range of motion tests without any extra instruments. This, the company claims, gives the surgeon the ability to determine precise implant position for optimal stability before introducing a solid stem within the femoral canal. The monolithic stem enables surgeon to avoid placing a modular, mid-stem junction at a critical, high stress location for the stem.
The system is available in two different stem styles—a proximally fluted or sleeveless stem for use when proximal bone defects are limited, and a modular sleeved stem for cases where proximal and distal bone defects are more prevalent. The system also uses Smith & Nephew’s proprietary Rocktite flutes, which deliver distal fixation for all defects. According to Smith & Nephew, both stem styles were well received by surgeons during the pre-launch evaluation.
“Modularity [multi-piece stems] is critical in today’s increasing complicated total hip revision surgery,” said Mathias Bostrom, M.D., of the Hospital for Special Surgery in New York, N.Y. “As the revision becomes more complex, modularity is what allows me to restore center of rotation, return leg length and provide a stable hip for my patients.”
Redapt is customizable due to its five available neck options, four of which can be inverted. Combined, there are 54 possible head center options. Each neck is compatible with Smith & Nephew’s cobalt chrome, ceramic, and Oxinium heads.
“Our goal was to create one system that surgeons could rely on for any type of revision from mild to severe,” says Gaurav Agarwal, general manager for Smith & Nephew’s Advanced Surgical Devices Division. “Not only did we achieve our goal, we created a system that’s revolutionary in its versatility, its simplicity and its reproducibility.”
