RESUMEN
OBJECTIVE: To evaluate the indications, surgical techniques and clinical effects of the fixation of posterior malleolus in complicated external rotation ankle fractures and illuminate the importance of anatomical reduction and rigid internal fixation of posterior malleolar fracture. METHODS: From July 2007 to June 2009, 32 patients were treated with open reduction and internal fixation,involving 21 males and 11 females with an average age of 36 years old (ranged from 19 to 68 years old). According to Lauge-Hansen classification: 13 cases of pronation-external rotation type (IV), 7 and 12 cases of supination-external rotation type (III and IV). Postoperative functional exercise and regular follow-up were done and outcomes were assessed. RESULTS: All the patients were followed up,and the duration ranged from 7 to 20 months,with an average of 14.5 months. According to Ankle Hindfoot Clinical Rating System of the American Orthopaedic Foot & Ankle Society (AOFAS), 23 patients got an excellent result, 7 good, 2 fair, 0 poor. CONCLUSION: Anatomical reduction and rigid internal fixation of posterior malleolar fracture as well as early functional exercise have significance in restoring ankle joint function and reducing the incidence of traumatic arthritis.

OBJECTIVE: To explore operative method in the treatment of syndesmosis injury of ankle fractures. METHODS: Twenty-four patients with ankle fractures and syndesmosis diastasis were treated with shape memory fracture staples, including 10 males and 14 females ranging in age from 19 to 71 years, with an average of 43 years. All patients were diagnosised with history, body examination and image data and were operated according to classification of Lauge-Hansen. RESULTS: All patients were followed up from 6 to 28 months with an average of 16 months, and all fractures healed, with a mean time 9.2 (8 to 14) weeks. Only one case had radiological and clinical manifestations of traumatic arthritis, but no breakage of shape memory fracture staple in all cases. Sixteen patients got excellent results, good in 5, fair in 2, poor in 1. CONCLUSION: Shape memory staple fixation for the treatment of syndesmosis diastasis in ankle fractures not only can perseve the physical motion of ankles, but also be remove earlier before weight bearing.
