Suture button construct with dog bone shaped button for acromioclavicular joint fixation

摘要

Systems for AC joint repair using a fixation device having a specific "dog bone" configuration in a minimally invasive approach. One AC fixation system is formed of dog bone shaped buttons and at least one suture tape used to secure the buttons during an AC joint repair. The buttons are provided with openings that allow the passage of suture/tape limbs. Another AC joint fixation system is formed of a metal button inserted over a fused/joined construct having multiple flexible strands. The fused/joined construct is formed of multiple independent and separate suture strands and/or suture tapes that are joined (fused together) at about the midpoint of the tapes and/or sutures, resulting in multiple independent limbs of suture/tape. A suture tape loop construct having an integrally formed eyelet at one end of the loop may also be used in the fixation systems.
