Syndesmotic Injuries Clinical Trial
Official title:
Bilateral External Torque CT, a Novel Diagnostic Tool for Detection of Syndesmotic Insufficiency
Study population: the investigator set them sample size to 30 patients. Primary endpoint (concerning both study questions): is the applied torque measurement in Newton meters (maximum up to 7.5 Nm) up to the pain tolerance limit. For the chronic injuries, a minimum of 5 Nm should be achieved. If this is not possible due to pain, an intra-articular infiltration into the upper ankle joint with 5ml Ropivacaine 2% is performed under sterile conditions. In addition, fibula translation while exercising the maximum tolerated External Torque CT (maximum up to 7.5 Nm). Secondary endpoint (1st study question): the comparison to stress fluoroscopy without anesthesia and under anesthesia. Secondary endpoint (2nd study question): the comparison of patients with and without symptoms. Secondary endpoint in patients who received intra-articular infiltration is the increase in tolerated Newton meters.
