Case-control study on robot-assisted core decompression and conventional core decompression for early necrosis of femoral head / 中国骨伤

ABSTRACT

OBJECTIVE@#To compare clinical effect of robot-assisted core decompression and conventional core decompression in treating ARCO Ⅰ stage necrosis of femoral head.@*METHODS@#A retrospective analysis was performed on 60(unilateral operation) patients who underwent core decompression for femoral head necrosis from February 2018 to February 2020. Among them, 30 patients(30 hips) were underwent robot-assisted core decompression (RCD group), including 19 males and 11 females, aged from 17 to 58 years old with an average of(38.50±10.61) years old;30 patients(30 hips) were underwent traditional core decompression surgery (CCD group), including 20 males and 10 females, aged from 20 to 55 years old with an average of (40.63±10.63) years old. Intraoperative fluoroscopy times, intraoperative blood loss and operation time between two groups, and Harris score, visual analogue scale (VAS) before opertaion and 24 months after operation were compared.@*RESULTS@#All patients were followed up, RCD group followed up from 21 to 26 months with an average of(23.40±1.65) months, CCD group followed up from 21 to 26 months with an average of (23.30±1.66) months, and had no difference between two groups(P>0.05). The number of intraoperative X-ray fluoroscopy, intraoperative blood loss and operative time in RCD group were (9.43±1.14) times, (153.80±22.04) ml, (33.40±1.87) min, respectively;while(19.67±1.32) times, (165.04±20.41) ml and (54.75±3.46) min in CCD group respectively;and there were statistical difference between two groups(P<0.05). In addition, there were no statistical difference between two groups in Harris score and VAS at 24 months after operation(P>0.05).@*CONCLUSION@#Compared with conventional core decompression, robot-assisted core decompression could reduce the number of intraoperative fluoroscopy, shorten operation time, and reduce risk of surgery.
