Plain English summary of protocol

Background and study aims
Syndesmotic injuries are injuries to the ligaments that connect the bones of the lower leg to the ankle joint. The current gold standard treatment for these is screw fixation where the bones are screwed together. However, this leads to problems due to the limited movement of the joint. Newer such devices as flexible TighRope Knotless have been developed which allow healing to take place without the use of screws.
The aim of this study is compare screw fixation with flexible fixation.

Who can participate?
Patients with a syndesmosis injury combined with an ankle fracture identified by clinical examination and X-ray

What does the study involve?
Participants will be randomly allocated to receive either dynamic (TighRope Knotless) or static fixation (Screw). Follow up is at 3, 6 and 12 months following surgery.

What are the possible benefits and risks of participating?
TighRope Knotless does not require a knot reducing wound complications related to the suture knot reported in previous studies performed with classic TighRope. This reduces risks related to a second surgery such as loss of reduction or infection.

Where is the study run from?
University Hospital Infanta Sofía, Madrid (Spain)

When is the study starting and how long is it expected to run for?
March 2019 to November 2023

Who is funding the study?
Foundation of Spanish Trauma and Orthopedic Surgery Society (SECOT).

Scientific titleClinical and functional results of screws and TighRope Knotless device in the treatment of syndesmosis acute injuries: a randomized controlled trial
Study objectivesNew-generation suture button device (TighRope Knotless) would provide similar results as screw fixation in syndesmosis injuries.
Ethics approval(s)Approved 28/03/2019, Ethics committee of the University Hospital LA PAZ (P.º de la Castellana, 261, 28046 Madrid, Spain; +34 91 727 75 30; secretariatecnica@idipaz.es), ref: 5242
Health condition(s) or problem(s) studiedTreatment of syndesmosis injury
InterventionDuring surgery, once bone fractures have been fixed, the lesion of syndesmosis is verified by performing an external rotation stress test with the radiological study. If the patient suffers a syndesmosis injury, we open a randomization envelope and treat the injury with the corresponding implant: screw or tighrope.
All patients in both treatment groups are treated with a splint postoperatively for two weeks.
Afterwards, mobilization without load is allowed for a month and then progressive load begins. Until six months after surgery, impact sports activities are not authorized. All patients are reviewed two weeks after the intervention, one month, and at 3,6 and 12 months.
