Smith & Nephew Releases Capture-Head Orthopedic Screw

London, United Kingdom-based Smith & Nephew plc has released the Trigen low-profile screw, a “captured” head screw for orthopedic applications. A captured screw head has internal threads designed to securely attach the screw to the screwdriver, potentially removing the risk of a screw being lost during surgery.

Low-profile screws can help reduce irritation to surrounding soft tissue because they do not protrude as much as traditional bone screws.

“The new Trigen low-profile screws are the best of three worlds,” said William Ricci, M.D., professor of orthopedic surgery and chief of orthopedic trauma service at Washington University School of Medicine in St. Louis, Miss. “They are low profile, they provide excellent feel related to when the screw head is down to bone, and they retain the capture feature.”

The new screws are available in 2.5 mm increments and also feature a fluted design that reportedly helps surgeons tactilely detect when the screw is fully seated.

“Within this one screw, our commitment to improving surgical outcomes for both patients and surgeons is on full display,” said Gaurav Agarwal, vice president and general manager for Smith & Nephew’s Advanced Surgical Devices Division.

The Trigen low-profile screw is used with the entire Trigen system, a portfolio of nailing options for long bones that addresses lower-extremity fractures. Consisting of three patented nail designs, the Trigen system’s special “working channel” approach is intended for a simplified procedure, a smaller incision, enhanced soft tissue management, and improved access to the bone.

The new low-profile screws also can be used with Smith & Nephew’s Trigen Sureshot distal targeting system. The Sureshot system is a virtual, real-time imaging system that reportedly allows surgeons to distally lock screws without the use of fluoroscopy. The intention is greater accuracy, easier alignment and less radiation exposure for the patient, surgeon, and surgical staff in the operating room.

Smith & Nephew develops technology in the orthopedic reconstruction, advanced wound management, and sports medicine and trauma spaces.
