“…Several groups have previously modified suture button devices 30 or implementation of such devices 32 with the intention of improving mechanical function, particularly in the sagittal plane. However, as was also determined in our work, modified flexible fixation devices tend to result in biomechanics similar to those of commercially available suture button constructs implemented according to manufacturer guidelines.…”

“…However, as was also determined in our work, modified flexible fixation devices tend to result in biomechanics similar to those of commercially available suture button constructs implemented according to manufacturer guidelines. 30 The metallic augmentation of the prototype suture button device used in this work was intended to address complications such as bone tunnel erosion rather than to modify device mechanics. Though no evaluation of long-term bone tunnel erosion could be performed in this cadaveric study, the biomechanical similarity in rotational stability of the prototype device compared to the suture button group indicated that the prototype design was functionally very similar to existing methods for syndesmotic repair.…”

“…The distal tibiofibular syndesmosis comprises 2 bones and 4 ligaments and is a delicate structure. It provides a dynamic relationship for the tibia and fibula during ankle motion (19,20). The main treatment of distal tibiofibular syndesmosis injury includes conservative care and surgery.…”

Unstable external-rotation type ankle fractures with concomitant syndesmosis injury commonly occur. Syndesmosis screw fixation has long been regarded as a reference standard treatment for syndesmosis injury. However, its complications and biomechanical disadvantages have become controversial; thus, we designed a novel elastic syndesmosis hook plate (ESHP) that combines the features of both rigidity and flexibility. The purpose of the present study was to introduce this new method and compare its clinical outcomes with those of routine screw fixation. We randomized 25 patients to the screw fixation group and ESHP group. The average follow-up period was 12 months. The clinical outcomes included malreduction or loss of reduction, overall complications, and function. During the follow-up period, 3 cases (25%) of malreduction were found in screw fixation group on postoperative computed tomography. In the ESHP group, only 1 patient (7.69%) had a narrowed anterior gap between the distal tibia and fibula. However, the difference in the malreduction rate between the 2 groups was not significant statistically (p = .32). The overall complication rate in the ESHP group was lower than that in the screw group, although no significant differences were found between the 2 groups. The mean visual analog scale scores in the ESHP and screw groups were 1.46 ± 1.33 and 2.42 ± 2.07, respectively. The average dorsiflexion range of motion in both groups was satisfactory (14.77° versus 12.83°; p = .16). However, a statistically significant difference was found in the plantarflexion range of motion between the 2 groups (p < .05). In addition, the ESHP group had an earlier time to return to work (p < .05). The ESHP fixation construct can stably fix syndesmosis, retain the physiologic micromotion function of the syndesmosis, and results in fewer complications compared with routine syndesmosis screw fixation for syndesmotic instability. In conclusion, our results have shown ESHP to be a viable method for treatment of syndesmosis instability.

“…Some limited investigations have attempted to compare dynamic suture button fixation with syndesmotic screw fixation [54,[57][58][59][60][61][62]. Westermann et al performed a cadaveric study to see if there was a difference in the malreduction of syndesmotic injuries when comparing screw fixation with tightrope fixation [58].…”

Ideal management of the various presentations of syndesmotic injury remains controversial to this day. High quality evidentiary science on this topic is rare, and numerous existing studies continue to contradict one another. The primary reasons for these discrepancies are that previous studies have failed to (1) properly distinguish between isolated (nonfractured) and non-isolated injuries, (2) accurately define stable from unstable injuries, and (3) sufficiently differentiate between acute and chronic injuries. The purpose of this review is to summarize today's body of literature regarding diagnosis and management of syndesmotic injury and discuss current trends and important future directions to optimize care of this very heterogeneous population.

Biomechanical comparison of bionic, screw and Endobutton fixation in the treatment of tibiofibular syndesmosis injuries

Abstract: The bionic fixation at least equals the performance of Endobutton fixation; it also allows more physiologic movement of the syndesmosis when compared to the screw fixation and may serve as a viable option for the fixation of the tibiofibular syndesmosis.
