Suture Button Fixation in Shoulder Instability Surgery to Achieve Bone Healing: A Critical Analysis Review

» Suture button fixation has emerged as an effective surgical construct in arthroscopic and open Latarjet and anterior glenoid reconstruction with free autograft bone with high rates of bone block healing. » Biomechanical data suggest that screw and suture button mechanical fixation constructs provide similar load to failure and stability for the Latarjet procedure. » Preliminary bone healing models have identified that flexible fixation may exhibit a higher degree of bone callus maturation, whereas rigid fixation results in excessive callus hyperplasia » Mechanical tensioner use provides consistent tensioning of suture button constructs and improves bone-to-bone healing rates when used for anterior glenoid reconstruction surgery. » Evidence is lacking regarding the reliability of bone-to-bone healing of allografts to native bone with use of suture button constructs. » Suture button fixation provides good short- and mid-term clinical outcomes for the arthroscopic Latarjet and anterior glenoid reconstruction with free autograft bone.
