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

Abstract

» 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.
