A new bioresorbable implant utilizes ultrasonic energy to liquefy and flow into cancellous bone to provide stable soft tissue to bone fixation.
The Stryker (Kalamazoo, MI, USA) SonicAnchor is a bioresorbable implant made of poly-L-DL-lactic acid (PLDLLA), which is placed into a hole drilled into the cancellous bone. Once high frequency, low amplitude ultrasonic energy is applied to liquefy the tip of the implant, PLDLLA flows into the bone cavities. Following cessation of the ultrasound pulse, the material re-solidifies and hardens, providing stable three-dimensional (3D) anchoring within five seconds.
The SonicAnchor is intended for suture or tissue fixation in foot, ankle, knee, hand, wrist, elbow, and shoulder open procedures.
