Clinical observation of tibial Pilon fractrure with multi-plate capture internal fixation

Objective To investigate the curative effect of the multi-plate capture internal fixation for tibial Pilon fracture.Methods In this study,87 patients with tibial Pilon fracture were enrolled.According to Ruedi-Allgower classification,there were 11 cases of type Ⅰ,51 cases of type Ⅱ,and 25 cases of type Ⅲ.Except 11 cases of type Ⅰ and 3 cases of type Ⅱ with serious skin contusion,the other 73 cases all used multi-plate capture internal fixation.The postoperative function of the ankle joint was evaluated using Mazur criteria.Results All the cases were followed up for 6-16 months(average 7.66 months).The healing time was 12 to 19 week(average 14 weeks).The results were excellent in 51 cases,good in 17 cases and fair in 5 cases according to Mazur's criteria.The excellent and good rate was 93%.There was no wound infection,delayed fracture healing or nonunion.The function of the ankle joint was good in each case.Conclusions Treating Pilon fractrure with multi-plate fixation accords with AO fixation principle.Because the plate is thin,it has strong plasticity.The thin screw has little impact on blood circulation of the fracture ends or on bone quality.The advantage of this method lies in simple operation,fixation reliability,early functional exercise,little trauma and few postoperative complications.The effect is satisfactory.
