Clinical study on closed reduction and interlocking intramedullary nail fixation for the treatment of humeral surgical neck fractures under the guidance of orthopedic surgical robots
Objective To investigate the clinical effect of closed reduction and interlocking intramedullary nail fixation in the treatment of humeral surgical neck fractures under the guidance of orthopedic surgical robots.Methods 60 cases of humeral surgical neck fractures were selected as the research subjects.They were divided into a control group and an observation group based on the surgical procedures,with 30 cases in each group.Patients in the control group underwent open reduction and locking plate internal fixation treatment,while patients in the observation group underwent closed reduction and interlocking intramedullary nail internal fixation under the guidance of orthopedic surgical robots.Comparison was made on the surgical time,incision length,intraoperative bleeding volume,fracture healing time,visual analogue scale(VAS)score,and Neer shoulder joint function score,and postoperative complications between the two groups.Results In the observation group,the surgical time of(80.13±22.17)min was significantly longer than(62.60±16.12)min in the control group,the surgical incision length of(4.23±1.85)cm was shorter than(10.87±2.71)cm in the control group,the intraoperative bleeding volume of(68.53±25.87)ml was less than(143.63±30.37)ml in the control group,and the fracture healing time of(9.40±1.43)weeks was significantly shorter than(14.17±2.87)weeks in the control group.The difference was statistically significant(P＜0.05).The VAS score of(3.77±1.14)points at 1 week after surgery of the observation group was significantly lower than(4.37±1.03)points of the control group,and the Neer shoulder function score of(55.63±4.76)points at 1 month after surgery was significantly higher than(47.53±4.79)points of the control group.The difference was statistically significant(P＜0.05).There was no statistically significant difference in VAS score at 1 month after surgery and the Neer shoulder function score at 3 months after surgery between the two groups(P＞0.05).No complications such as radial nerve injury,wound infection,avascular necrosis of the head of the humerus,varus deformity union,internal fixation rupture or screw removal were observed in the two groups at the last follow-up.Conclusion Closed reduction and interlocking intramedullary nail fixation under the guidance of orthopedic surgical robots for the treatment of humeral surgical neck fractures increases the surgical time compared with traditional open reduction and locking plate internal fixation treatment,but with smaller incisions,less bleeding,and good postoperative functional recovery of the patient,which is a minimally invasive,effective,and safe treatment method.
