Background: Syndesmosis injury and rupture is quite common in Lauge–Hansen external-rotation type ankle fractures (ERAF). The injured syndesmosis may remain unstable even the fractures are well reduced and fixed. The aim of this work is to compare between Suture-Button and Syndesmosis Screw as treatment of Syndesmotic Rupture.
Methods: This prospective randomized study was conducted on Forty patients with ankle fracture admitted to Orthopedic Surgery unit., at Benha from Jan 2022 to September 2023. Forty Patients were randomly enrolled, the allocation of the patients into each group was done using a 1:1 computer-generated sequencing placed in sealed envelopes into three groups:
Group A SS (N=20): patients were treated with Syndesmosis Screw, Group B SB (N=20): patients were treated with Suture-Button.
Results: Regarding the mean total score of The American Orthopaedic Foot & Ankle Society (AOFAS), at 3 months, the mean score in group A was 58.5±12.9 and in group B was 64.75±10.9 with p-value 0.05(p-value ≤0.05 is statistically significant). At 6 months, the mean total score in group A was 86.95±11.45 and in group B was 94.15±5.35 with p-value 0.005.
Conclusions: The dynamic fixation of acute syndesmosis injuries by tightrope gives better clinical outcomes than static fixation at 3 and 6 months follow up. the implant offers adequate syndesmosis stabilization without the risk of screw breakage. Also, it decreases the reoperation rate.
