Abstract：Objective Tocompareclinicalefficacybetweenpercutaneousreductionhollowscrewinternalfixationand openreductionplateinternalfixationinthetreatmentofSandersⅡ、Ⅲtypecalcanealfracture.Methods 6casesoffreshand unilateral SandersⅡ、Ⅲ type calcaneal fractures from October 2011 to September 2012 were divided into group A and group B. Both group has 28 cases. The cases of group A were treated with percutaneous reduction and hollow screw internal fixation, and the cases of group B were treated with open reduction and plate internal fixation. We compared the two groups of patients with correlated observation index:operation time,intraoperative blood loss,incision healing time,hospitalization time after oper-ation,the imaging parameters before and after operation,the postoperative complications and the functional recovery of foot, whichwasevaluatedbyMarylandscore.Thenthedataofobservedindexeswerestatisticallyanalyzed.Results 56patients had been followed up for 12 months,significant difference could be found between operation time,peri-operative bleeding, wound healing time and hospitalization time;postoperative Bolher angle. Gissane angle and the excellent rate of functional re-covery between the two groups had no significant difference(P﹥0. 05),two groups of postoperative radiographic parameters had obviously improved than that before operation(P﹤0. 05);the group A was slightly higher than the group B in Maryland score and the excellent rate of functional recovery,but the difference was not statistically significant(P﹥0. 05). There were significantdifferencesbetweenthetwogroupsinthecomplicationincidence(P﹤0.05).Conclusion Minimallyinvasiveper-cutaneous reduction and hollow screw internal fixation for the treatment of SandersⅡ、Ⅲ type calcaneal fracture also can ob-tain good reduction and reliable fixation,and can not only lower intraoperative bleeding and postoperative complications,but can also shorten operation time,wound healing time and hospitalization time. So it is a reliable,effective and practical operation technology in the treatment of calcaneal fracture.
