| Objective The clinical effective comparison of open reduction and plate fixation (ORAPF) and the closed reduction with percutaneous screw fixation (CRWPSF) for Sanders II and Sanders III calcaneal fracture. Method Retrospective analysis showed hospital’s 84 cases (88 feet) of Sanders II and Sanders III calcaneal fracture from January 2009 to October 2019. There are 41cases (42 feet) adopting ORAPF and 43 cases (46 feet) adopting CRWPSF. The comparisons are from two groups preoperative time, the average length of operation, bleeding amount during the operation, the complications of operative incision, and the degree of calcaneal anatomical parameter, by utilizing the American Orthopedic Foot and Ankle Society (AOFAS) scoring system for the ankle function evaluation. Result The preoperative time, average operation time and the bleeding amount of the closure group is significantly better than those of open operation group, with significant statistically differences (P<0.05). The operative incision complications of the closure group are less than those of open operation group (P<0.05). According to the ankle function score, there is no statistical difference between the two groups in the calcaneus length, width and height before operation (P>0.05), with a statistical difference between pre-operation and post-operation(P<0.05). However, there was no statistically significant difference between the closure group and the open operation group in the calcaneus length, width and height after operation (P>0.05). There is no statistical difference between the two groups in calcaneal bass Angle and geocene Angle (P>0.05), with a statistical difference between pre-operation and post-operation(P<0.05). The recovery of calcaneal bass Angle and geocene Angle in open operation group is better than that of closure group, with significant statistically difference between pre-operation and post-operation(P<0.05)Conclusion The advantages of CRWPSF are shorter average length of hospital stay, shorter average operation time, minimal invasion and less complications, which is a good minimally invasive treatment. |
