Clinical Study of Different Bone Graft Materials in the Treatment of Calcaneal Bone Cyst
Objective:To explore the effect of different bone graft materials on the treatment of calcaneal bone cyst.Methods:The clinical data of 35 cases of calcaneal bone cyst treated by curettage and bone grafting were analyzed from June 2011 to August 2019.According to different implant materials,they were divided into group A and group B.18 cases in group A were treated with allogeneic transplantation(Xin Kangchen).17 cases in group B were transplanted with autologous iliac bone and allogeneic bone(Xin Kangchen),and the ratio was 1∶2.The perioperative indexes,serum indicators and inflammatory factor,the incidence of postoperative complications,the clinical cure rate 3 months and 4 months after operation,and AOFAS ankle hindfoot score preoperation and 5 months after operation were recorded.Results:The operation time and intraoperative bleeding in group A were lower or less than those of group B(t=9.204,18.470;P＜0.05).Serum alkaline phosphatase(ALP)and osteocalcin(BGP)in group A were better than those in group B 3 months after operation(t=7.036,5.481;P＜0.05).There was statistically significant difference in CRP between the two groups 1 month after operation(t=15.022,P＜0.05).CRP of group A was higher than group B 1 week after operation,recovery rate of group A was superior to group B 3 months after operation,and there was statistically significant difference in the compliance rate of two groups(P＜0.05).The AOFAS ankle-hindfoot score 5 months after operation of the two groups improved compared with those before operation(t=1.386,0.453;P＜0.05).Conclusion:Autogenous bone combined with allogeneic bone transplantation has an impact on the early healing rate compared with simple allogeneic bone transplantation after curettage of calcaneal bone cyst,while simple allogeneic bone transplantation influences the recovery of inflammatory indexes.But it has the advantages of shorter operation time,lesser trauma and lesser postoperative complications.
