ObjectiveTo investigate the clinical features of ankle fractures involving Tillaux-Chaput in adults, and to observe the surgical effectiveness.MethodsBetween May 2009 and May 2013, 15 adult patients with ankle fractures involving Tillaux-Chaput were treated by open reduction and internal fixation. There were 12 males and 3 females, with an average age of 32 years (range, 19-45 years). The causes included sport injury (8 cases), traffic accident injury (5 cases), and falling injury from height (2 cases). The left ankle was involved in 5 cases and the right side in 10 cases. There were 2 open fractures (Gustilo type I) and 13 close fractures. Five patients had single Tillaux-Chaput fractures. The mean time between injury and surgery was 8.5 days (range, 3 hours to 15 days). According to the Lauge-Hansen classification, there were 9 cases of supination-external rotation, 5 cases of pronation-external rotation, and 1 case of pronation-abduction.ResultsPrimary healing of incisions was obtained in 13 patients without infection and neurovascular injury; 2 patients had superficial infection which was cured after oral antibiotics and dressing change. All cases were followed up for 23 months on average (range, 13-36 months). X-ray films showed complete fracture healing at 10-16 weeks postoperatively (mean, 13 weeks) in all cases. The mean American Orthopaedic Foot and Ankle Society (AOFAS) score was 87 (range, 78-99), with an excellent and good rate of 80% (excellent in 9 cases, good in 3 cases, and fair in 3 cases).ConclusionOpen reduction and internal fixation for ankle fractures involving Tillaux-Chaput in adults can achieve excellent effectiveness.
