    Abstract:
    OBJECTIVE: To explore clinical efficacy of cannulated screw internal fixation in treating sustentaculum tali fractures with articular surface. METHODS: From August 2012 to June 2017, 13 sustentaculum tali fracture patients with articular surface were treated by cannulated screw internal fixation, including 10 males and 3 females, aged from 26 to 58 years old. Joint plane flatness was evaluated by calcaneal width, clearance distance of middle-range and posterior talar articular surface on coronal position of CT scan before operation and 1 year after operation. AOFAS score at 1 year after operation was applied to evaluate clinical efficacy. RESULTS: All patients were followed up from 9 to 70 months. The fractures were healed well from 8 to 16 weeks. No subtalar arthritis and tenosynovitis occurred. Calcaneal width before operation was from 46.2 to 52.7 mm, and decreased from 35.2 to 39.2 mm after operation; clearance distance of middle-range before operation was from 4.5 to 4.8 mm, and decreased from 1.9 to 2.2 mm after operation; clearance distance of posterior talar articular surface before operation was from 2.4 to 2.8 before operation, and decreased from 1.9 to 2.3 mm after operation. AOFAS score at 1 year after operation ranged from 77 to 94, and 1 got excellent result and 12 moderate. CONCLUSIONS: The clinical efficacy of two cannulated screws with cross internal fixation for sustentaculum tali fractures with articular surface is satisfactory, sustentaculum tali fracture could obtain good reduction, recover smooth of middle talar articular surface, and the function of feet were improved.
