Application Research Of Minimally Invasive SuperPATH Surgical Approach In Total Hip Arthroplasty

Objective: To compare the clinical efficacy of minimally invasive SuperPATH approach and direct anterior approach(DAA)in total hip replacement surgery.Methods: A total of 9 6 patients with hip joint disease who met the inclusion criteria and required surgical treatment were selected from the Department of Orthopedics of Gansu Provincial People’ s Hospital from January 2 0 1 9 to August 2 0 2 2.The included patients were randomly divided into SuperPATH approach and DAA approach group(4 8 cases in each group).The two groups underwent unilateral minimally invasive total hip replacement using SuperPATH approach and DAA approach,respectively.Patients were followed up for a long time after surgery.In addition,the clinical efficacy of the two groups was compared by surgical parameters(incision length,operation time,intraoperative blood loss,postoperative drainage volume,acetabular abduction Angle and anterior inclination Angle of the prosthesis)and prognostic function indicators(Harris score,VAS score,etc).Results: The results showed that there were statistically significant differences in operation time,incision length and intraoperative blood loss between the SuperPATH group and the DAA group(P < 0.0 5),and the above indexes in the SuperPATH group were significantly lower than those in the DAA group.There was no significant difference in postoperative drainage volume between the two groups(P > 0.0 5).There was no significant difference in VAS pain scores at 1 month,3 months and 6 months between the two groups(P > 0.0 5).There were statistically significant differences in Harris functional scores at 1 month,3 months and 6 months after surgery between the two groups(P=0.013,P=0.020,P=0.031),and the Harris functional scores in SuperPATH group were significantly higher than those in DAA group.During postoperative hospitalization,1 patient in DAA group had hip dislocation(2.08%),closed traction reduction under anesthesia,assisted traction for two weeks,recovery and discharge.X-ray reexamination after surgery in the DAA approach group revealed3 patients with minor trochanteric fracture(6.2 5 %),and 2 patients with deep venous thrombosis of lower limbs(4.17%)were reported in the DAA group.None of the patients in the two groups developed postoperative infection,and none of the patients developed complications and were readmitted to hospital within 1 month after discharge.Conclusions: Compared with the DAA approach,the SuperPATH approach for total hip replacement has the advantages of less surgical trauma,faster postoperative functional recovery,and higher surgical safety,which can provide patients with better clinical efficacy and medical experience.
