Objective To summarize the short-term effectiveness of TightRope system for the treatment of syndesmotic tibiofibular diastasis. Methods Between June 2013 and June 2015, 23 patients with syndesmotic tibiofibular diastasis were treated by TightRope system, including 15 males and 8 females with an average age of 32.3 years (range, 16-63 years). Injury was caused by sports in 13 cases, by traffic accident in 6 cases, and by falling from height in 4 cases. The locations were the left side in 13 cases and the right side in 10 cases. The time from injury to operation was 6 hours to 12 days (mean, 3.8 days). According to Lauge-Hansen classification, 13 cases were rated as supination-external rotation type, 7 cases as pronation-abduction type, and 3 cases as pronation-external rotation type; according to Weber classification, 5 cases were rated as type A, 11 cases as type B, and 7 cases as type C. Results The mean operative time was 68.1 minutes (range, 48-93 minutes); the mean intraoperative blood loss was 70.3 mL (range, 20-150 mL); and the mean hospitalization days were 7 days (range, 5-13 days). Superficial local skin necrosis occurred in 6 cases, and primary healing of incision was obtained in the others. All patients were followed up 8-30 months (mean, 16.4 months). X-ray films showed bone union was achieved within 6-12 weeks (mean, 9.4 weeks). No related complications of reduction failure and re-fracture occurred. The internal fixators were removed at 10-18 months postoperatively (mean, 13.3 months). According to American Orthopaedic Foot and Ankle Society (AOFAS) score for ankle function evaluation, the results were excellent in 19 cases and good in 4 cases at last follow-up. Conclusion TightRope system is a good method to treat syndesmotic tibiofibular diastasis, because of safety, convenient operation, and satisfactory short-term effectiveness.
