BACKGROUND:The ankle fusion is an important treating means of end-stage ankle joint disease. Internal fixation of implant has become the preferred way of fixation, but fixation of different implants has different effects. OBJECTIVE:To explore the value of different internal fixation methods in ankle fusion. METHODS:A retrospective analysis was performed in 64 cases of ankle fusion from September 2012 to March 2015. They were divided into the observation group (32 cases) and control group (32 cases) according to the way of internal fixation of implant. The observation group underwent headless compression screw fixation. The control group underwent interlocking compression plate fixation. Length of incision, operation time, postoperative drainage volume, postoperative complications, healing time of bone and functional recovery of ankle-hindfoot were observed and compared between the two groups. RESULTS AND CONCLUSION:(1) There was no statistical significance in operation time and healing time of bone between the two groups (P>0.05). (2) Length of incision and postoperative drainage volume were significantly greater in the control group than in the observation group. The incidence of postoperative complications was significantly higher in the control group than in the observation group (P0.05), but the score was significantly higher in the observation group than in the control group in final fol ow-up (P<0.05). (4) These findings suggest that compared with the interlocking compression plate, headless compression screw treatment for ankle fusion can obtain better effect, smal trauma, less postoperative complications, fixed firmly, more in line with the physiological and biomechanical requirements.
