Suture Anchor Aids Reattachment of Soft Tissue

A new bioresorbable suture anchor system is used for soft tissue reattachment to bone, primarily in the treatment of rotator cuff injuries.

The anchor is made from a self-reinforced copolymer, resulting in a stronger device that does not require surgeons to deviate from standard technique. Moreover, the anchor maintains 90% of the eyelet tensile strength through the 12-week healing period. Called the Duet Suture Anchor, the device was developed by Bionx Implants, Inc. (Blue Bell, PA, USA), a developer and manufacturer of polymer implants for use in orthopedic surgery. The company says the new suture has three advantages over other anchor products: a gradual loss of stiffness to reduce stress shielding, radiolucence to prevent interference with post-surgical radiographs, and complete absorption of the implant to eliminate need for removal.

"We are extremely pleased that we have been able to work with a leading group of orthopedic surgeons to develop the Duet Suture Anchor, which is an improvement over other anchors that are being used for rotator cuff repairs,” said Gerard S. Carlozzi, president and CEO of Bionx.
