Clinical diagnosis and treatment features of Maisonneuve fracture and analysis of clinical outcome of 15 patients / 中国骨伤

ABSTRACT

OBJECTIVE@#To explore clinical diagnosis and treatment features of Maisonneuve fractures (maisonneuve fractures of the fibula, MFF), and evaluate its clinical effects.@*METHODS@#From March 2017 to June 2018, 15 patients with MFF were treated with operation, including 9 males and 6 females, aged from 27 to 54 years old with an average of (35.00±7.46) years old, the time from injury to operation ranged from 5 to 8 days with an average of (6.33±1.04) days. All the fractures were fresh and closed injury. The time of bone union and postoperative complications were observed, and AOFAS score was used to evaluate recovery of ankle joint function at 12 months after operation.@*RESULTS@#All patients were followed up from12 to 28 months with an average of (17.00±3.79) months. Four patients were misdiagnosed. All fractures were obtained bone union from 4 to 6 months with an average of (4.80±0.94) months. No postoperative complications such as infection, delayed union or nonunion occurred. Postoperative AOFAS score at 12 months was 90.23±7.27, among which 9 patients got excellent result, 3 good, and 3 fair.@*CONCLUSION@#Maisonneuve fracture is an unstable fracture. High fibular fracture and the separation of the lower tibia and fibula could be easily neglected, which could lead to misdiagnosis and missed care. Surgical treatment could recover anatomical relation of the lower tibia and fibula and ankle mortise, and obtain satisfying clinical effect.
