Abstract:
Objective:To compare the clinical effects robot navigation assisted and conventional proximal femoral nail antirotation (PFNA) implantation and fixation in the treatment of elderly femoral trochanteric fractures.Methods:A total of 86 elderly patients with tuberosity fracture of the femur were admitted as research samples from January to March in 2022 in the Department of Trauma Orthopaedic, Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University, including 37 males and 49 females, who aged from 63 to 92 years, with an average age of (79.6 ± 6.9) years. All patients were treated with intramedullary nails (PFNA), 32 with dimensity robotic-assisted therapy (robot group) and 54 with traditional methods (conventional group). The length of incision, the number of intraoperative fluoroscopy, the amount of intraoperative blood loss, and the operation time were recorded. The occurrence of postoperative complications in the two groups was observed. The rate of excellent hip Harris score at 3 month after surgery was compared between the two groups. Measurement data with normal distribution were represented as mean ± standard deviation( ± s), and the comparison between groups was conducted using the t-test; the comparison of count data were represented as [ n(%)], and was conducted by Chi-square test or Fisher exact probability between groups. Results:All patients were followed up for 9 to 12 months, with an average of (10.6 ± 0.9) months. The incision length and tip apex distance (TAD) of the robot group were (3.40±0.82) cm and (21.85±1.44) mm, which were smaller than (4.82±0.75) cm and (26.83±1.75) mm in the conventional group ( P<0.05 for all). The number of intraoperative fluoroscopy and guide needle adjustment [(14.53±3.26) and 0 times] in the robot group were less than those in the conventional group [(20.67±4.84) and (2.83±1.42)] ( P<0.05). The intraoperative blood loss and drainage rate of the robot group were (87.03±9.41) and (46.40±8.91) mL, which were smaller than that of the conventional group [(110.00±12.52) and (69.62±10.22) mL] ( P<0.05). There was no significant difference in the number of days of hospitalization and operation time between the two groups ( P>0.05). The postoperative complication rate in the robot group was 9.4%, which was lower than that in conventional group (42.6%), and the difference was statistically significant ( χ2=11.88, P=0.036). The excellent rate of postoperative hip joint function in the robot group was 75.0%, and the conventional group was 66.7%, and there was no significant difference between the two groups ( χ2=0.66, P=0.416). Conclusion:Robot-assisted navigation downward PFNA surgery can have good clinical effect in the treatment of femoral tuberosity fracture in the elderly, which can reduce the number of surgical incisions and intraoperative fluoroscopy, and reduce the incidence of postoperative complications, which is helpful to achieve minimally invasive surgery and rapid recovery of elderly patients with femoral tuberosity fracture.
