Abstract：Objective To investigate the clinical effect of modified porous core decompression(CD)combined with vacuum sealing drainage(VSD)in the treatment of early avascular necrosis(AVN)of the femoral head in adults.Methods A total of 80 adult patients with early AVN admitted to the Affiliated Hospital of Hebei University of Engineering from May 2022 to January 2024 were retrospectively selected.According to the different surgical methods,they were divided into CD group(37 cases,treated with modified porous CD)and combined group(43 cases,treated with modified porous CD combined with VSD).The treatment effect,hip joint function,pain,hip joint activity and postoperative complications were compared between the two groups.Results The total effective rate of the combined group was higher than that of the CD group[95.3％(41/43)vs 81.1％(30/37)](x2=4.055,P=0.004).At 3,6,and 12 months after operation,the Harris hip scores of the combined group were higher than those of the CD group,and the visual analogue scale scores of pain were lower than those of the CD group(all P＜0.05).The range of motion of hip joint in the combined group was greater than that in the CD group at 6 months after operation(P＜0.05).The total incidence of long-term postoperative complications in the combined group was lower than that in the CD group[7.0％(3/43)vs 24.3％(9/37)](x2=4.694,P=0.030).Conclusion Modified porous CD combined with VSD has a good effect in the treatment of adult patients with early AVN,which can improve hip joint function,control disease progression,reduce pain,increase hip joint activity,and has high safety.
