Abstract:

BACKGROUND: The injury of tibiofibular syndesmosis ligament often leads to traumatic arthritis and ankle instability and other sequelae if the diagnosis or treatment of tibiofibular syndesmosis ligament injury is not timely. At present, there is no clear report on the treatment of tibiofibular syndesmosis ligament injury with anchor.

OBJECTIVE: To retrospectively analyze the clinical efficacy and safety of double-strand anchor in the treatment of tibiofibular syndesmosis injury.

METHODS: From July 2016 to October 2018, 30 cases of ankle fracture with lower tibiofibular syndesmosis injury were treated in South Hospital of First People’s Hospital Affiliated to Shanghai Jiao Tong University. The patients were randomly assigned to two groups (n=15). In the experimental group, the lower tibiofibular syndesmosis was fixed with double strands of suture anchors. In the control group, the lower tibiofibular syndesmosis was fixed with screw. Age, gender, and preoperative swelling degree of the ankle joint were preoperatively recorded. Three-dimensional CT images of the ankle and X-ray anteroposterior and lateral images of the ankle were captured. X-ray films of ankle joint were obtained 1 day and 1.5, 3, 6, 12 months after operation. American Orthopaedic Foot and Ankle Society scores were assessed at 3, 6 and 12 months after surgery.

RESULTS AND CONCLUSION: (1) All surgical incisions healed at stage I, and no complications such as lower limb venous thrombosis, infection, nonunion of bone, loose anchor was found. (2) At 3, 6 and 12 months after surgery, there was no significant difference in American Orthopaedic Foot and Ankle Society scores between the two groups. American Orthopaedic Foot and Ankle Society scores were significantly higher than that before surgery in both groups (P < 0.05). (3) Within one year after the operation, 5 cases (33%) in the experimental group and 2 cases (13%) in the control group showed the enlargement of tibiofibular syndesmosis. (4) Results suggested that double-strand suture anchor treatment of tibiofibular syndesmosis injury has a certain effect, and high safety. However, there is a high probability of reseparation of tibiofibular syndesmosis post-operation.
