Abstract：Objective To compare the biocompatibility and repair effect of different internal fixation materials in the treatment of calcaneal fracture.Methods A total of 84 patients with calcaneal fracture treated from May 2020 to May 2022 were selected as the research subjects and divided into group A and group B according to different internal fixation materials,with 42 cases in each group.Absorbable screws were used for internal fixation in group A,and metal screws were used for in-ternal fixation in group B.Perioperative indexes,complications,repair effects,imaging indexes,and red cell immune indexes before and after surgery[synergistic tumor erythrocyte immune garland rate(ATER),direct tumor erythrocyte garland rate(DTER),and red blood cell C3b receptor garland rate(RBC-C3bR)]of the two groups were observed.Results The dura-tion of operation was shorter in group A than in group B,and the amount of intraoperative blood loss was less than that of group B(P＜0.01).There was no significant difference in weight-bearing time and fracture healing time between the two groups(P＞0.05).At 3 months after surgery,Gissane Angle,Bohler Angle and calcaneus height in the two groups were higher than those before surgery,and calcaneus width was smaller than that before surgery(P＜0.05),and there was no statistical signif-icance between the two groups(P＞0.05).At 3 d after operation,ATER,RBC-C3bR and DTER in the two groups were low-er than those before surgery,which,however,were higher in group A than in group B(P＜0.05).The total incidence of complications in group A was4.76%(2/42),which was lower than that of group B[23.81%(10/42)](P＜0.05).At 3 months after operation,there was no significant difference in the excellent and good rate of repair between the two groups(P＞0.05).Conclusion Absorbable screw and metal screw have similar effects in internal fixation of calcaneal fracture.The for-mer has more advantages in shortening the duration of operation,reducing intraoperative blood loss and complications,and al-leviating red blood cell immune challenge.
