To discuss the correlation between morphological changes in ankle mortise and ankle joint functions after a surgery for Ruedi-Allgower Type III Pilon fracture. A retrospective analysis was conducted for 60 patients who received operative treatment for Ruedi-Allgower Type III pilon fracture and attended a follow-up visit from January 2007 to December 2012, among which, 32 were male and 28 were female; aged 20-25 years and averaged at 38 years; the time for follow-up visit is at 18-24 months averaged at 20 months. On the X-ray film photographed at the last follow-up visit, the following indexes were measured: (I) Height of ankle mortise, (2) Width of ankle mortise, (3) Depth of ankle mortise, (4) Angle of ankle mortise coronal, (5) Angle of ankle mortise sagittal view The functions of ankle joint on the affected side were scored and grouped at the last follow-up visit based on such scoring methods as Mazur and the like. 41 cases were assigned to the Excellent Group, 12 cases were assigned to the Good Group and 7 cases were assigned to the Moderate+Poor Group. The correlation between morphological changes in the ankle mortise and functions was analysed based on comparison among the five indexes of the ankle mortises on the affected side and the unaffected side of 60 patients and comparison of the difference values of the indexes for the affected side and unaffected side among the three groups. The research has shown that all differences in width of ankle mortise, depth of ankle mortise, coronal view and sagittal view angles have statistical significance except that height of ankle mortise does not have statistical significance based on the comparison among various indexes for the affected sides and the unaffected sides of 60 patients. The remaining four difference values exhibit negative correlation with scores and difference values increase with decreasing scores. It indicates that treatment of ankle mortise width, depth, angles of coronal view and sagittal view during operation exhibits significant correlation with postoperative ankle joint functions. Anatomical reduction of ankle mortise width, depth, angles of coronal view and sagittal view for patients with Ruedi-Allgower Type III pilon fracture during operation imposes a significant effect on postoperative functions of ankle joints. Thus the anatomic form of ankle mortise should be recovered as much as possible.
