Objective In this paper,the advantages and disadvantages of robot-guided surgery and traditional surgery,as well as their clinical efficacy.And it compares with biplane orthopedic robot-assisted pore core decompression and traditional pore core decompression in the treatment of early femoral head necrosis.Methods This article selects in January 2018 to January 2021 were in the Affiliated Hospital of Inner Mongolia medical university,who was femoral head necrosis patients were treated by conservative surgery of 31 patients were involved in the study.This study uses a retrospective study method.According to the surgical ways,the patients separate into the robot core decompression(RCD)and the conventional core decompression(CCD)group.The RCD group operates by an orthopedic robot.CCD group treated with traditional core decompression operation.An orthopedic robot-assisted system was used to complete the decompression of the pulp core and compare it with the conventional decompression of the pulp core.The study collected contains age,sex,body mass index,and the Association Research Circulation Osseous(ARCO)stage.And it also includes operation time,the parallelism between interpositive and lateral radiographs of the hollow nail,operation time after skin opening.And the number of guide needle attempts,number of intraoperative fluoroscopies,and amount of blood loss also need to be in it.Harris hip score(HHS)and visual analog scale(VAS)apply to evaluate clinical functions and the efficacy of robot-assisted systems.The data of all follow-up patients were processed and analyzed by SPSS 23.0 statistical software.Results Surgery completes in both groups,and no postoperative incision infection,delayed healing,end plant rejection,and other complications observe.Postoperative follow-up data of the two groups were well preserved,and the follow-up time ranged from 16 to 24 months,with an average follow-up of 20 months.There were 15 patients in the RCD group,aged from 38 to 47 years,with an average of(42.00± 2.73)years;The average BMI was(25.57 ± 1.17)kg / m2;Arco stage Ⅱ a,Ⅱ B and Ⅱ C were 3 cases,5 cases,and 7 cases respectively;There were 16 patients in CCD group,aged from 39 to 50 years,with an average of(44.13 ± 3.14)years;The average BMI was(25.85 ±0.92)kg / m2;Arco stage Ⅱ a,Ⅱ B and Ⅱ C were 2 cases,8 cases,and 6 cases respectively.There were no significant differences in age,sex,BMI,and ARCO stage between the RCD and CCD groups(P>0.05).There was no significant difference in the duration of complete operation(P=0.783).The operation time after skin incision(P<0.001),the parallelism of anteroposterior film of hollow needle(P<0.001),and the parallel of the lateral film(P<0.001)were significant differences between the RCD and CCD group.So do the number of guide needle attempts(P<0.001),the number of intraoperative fluoroscopies(P<0.001),and the amount of blood loss(P<0.001).The clinical function of the RCD group and CCD group evaluates by HHS score and VAS score at 3,6,and 12 months after the operation,respectively,but there was no statistical significance(P>0.05).Conclusions 1.The core decompression assisted by an orthopedic robot based on a biplane positioning algorithm is superior to the traditional core decompression in the aspects of guide needle parallelism and bleeding volume in the decompression of the femoral head in the early stage of femoral head necrosis.So do the operation time completely and operation time after skin incision,intraoperative guide needle insertion time,intraoperative guide needle puncture times,and intraoperative radiation times.2.An orthopedic surgical robot can improve the accuracy of operation,reduce the trauma caused by the surgery,shorten the operation time and further reduce the risk of surgery.The operation mode of the robot is safe and reliable,which is worthy of further application and promotion. |
