Implant device and system for stabilized fixation of bone and soft tissue

A system for syndesmosis repair includes a flat band secured to bone by pulling a metal button through both the tibial and fibula bones, which button is then toggled into position to create tension, along the band, across the two bone segments to be fixated. Once the button is secure against the bone, flat suture tails against the lock at the initial insertion site serves to tension the band and bone segments in place. The system band offers syndesmosis repair with a knotless closure. The system is designed to provide this stabilized fixation for bone fractures, osteotomies, and arthrodesis, plus soft tissue to bone attachment, if desired. It is designed to apply a restorative fixation force across the tissue segments to stabilize them. The band's rigidity and compliant nature provides consistent and rigid fixation during the healing phase.
