ABSTRACT
Objective To explore the biomechanical property on Suture-Button and conventional screw fixating the distal tibiofibular syndesmosis injury.Methods The distal tibiofibular syndesmosis injury models were made by cutting the anteroinferior tibiofibular ligaments,posteroinferior tibiofibular ligaments,interosseous tibiofibular ligaments or deltoid ligaments of 8 fresh frozen calves.These models were randomly and equally divided into the two groups.The two groups were respectively fixed by Suture-Button and conventional screw.The contact area and peak intra-articular pressure of tibiatalar joint were measured by biomechanical testing methods and the stress and strain sensing technology.Results The maximal contact area and peak intra-articular pressure of Suture-Button fixation group had no significant differences with the conventional screw group by the four kinds of ankle flexion-extension angles in the sagittal plane (t =3.52,4.49,5.93,4.75,all P > 0.05),peak intra-articular pressure was also similarly improved (t =3.61,3.97,4.68,2.41,all P > 0.05).But biomechanical markers of two fixation groups had an improvement trend.Conclusion Suture-Button fixing the distal tibiofibular syndesmosis injury had similar biomechanical effect to compare with traditional conventional screw,and two fixation groups both improved trend to compare with ligament-cut group.
