Objective to explore the efficacy of internal fixation with hollow screws in the treatment of ankle fractures of Weber B type. Methods A total of 80 patients with ankle fractures of Weber B type aged 31-78 were selected and divided into two groups according to the admission time： the control group （n=39） was treated with open reduction and internal fixation method and the observation group （n=41） was treated with internal fixation with hollow screws. The duration of operation, intraoperative amount of bleeding, healing time, healing rate, AOFAS ankle score and the incidence of such complications as incision infection, malunion and fracture of internal fixture in the two groups were observed and the efficacy of internal fixation with hollow screws was evaluated. Results The duration of operation, healing time, intraoperative amount of bleeding and recovery of ankle function in the observation group were superior to those in the control group （P 〈 0.05）, while the difference of the incidence of such complications as incision infection, malunion and fracture of internal fixture between the two groups was of no statistical significance （P 〉 0.05）. Conclusion The treatment of ankle fractures of Weber B type with internal fixation with hollow screws has such advantages as minor operative wound, less amount of bleeding, quick healing and good recovery of ankle function after the operation, and is worth clinical popularization and application.
