The TFNA Augmentation System can be used to provide enhanced implant fixation in cases where the potential risk of cut-out is significant. Cut-out is a loss of implant anchorage or stability in the bone, frequently occurring in those with poor bone quality. It causes the femoral neck-shaft angle to collapse, andis aleading clinical complication during hip fracture surgery. Cut-out can also lead to reoperation, which increases risks to the patient and increases costs to the healthcare system.
Each year, more than 300,000 hip fractures occur in the United States.1 These fractures are common in the elderly, especially those with osteoporotic bone. Fractures are expected to increase as the population ages.2 When used together with the TFNA System, the TFNA Augmentation System is designed to help reduce the risk of cut-out and provide enhanced implant fixation.3,4
“The TFNA Augmentation System addresses an important clinical need for patients who undergo hip fracture surgery, especially those who suffer from poor bone quality,” said Charisse Y. Sparks, M.D., Franchise Medical Leader Trauma, DePuy Synthes Trauma. “This new system complements the TFNA System and has the potential to improve patient outcomes, reduce costs, and increase patient satisfaction.”
DePuy Synthes, part of the Johnson & Johnson Medical Devices Companies, provides a comprehensive orthopedics portfolio in specialties including joint reconstruction, trauma, craniomaxillofacial, spinal surgery and sports medicine.
