Abstract:
Objective To investigate the effect of percutaneous plucking reduction and internal fixation technology on the levels of norepinephrine (NE) and angiotensin II receptor antagonist, AngⅡ (AngⅡ) and hip joint function in elderly patients with irreversible intertrochanteric fractures.
Methods A total of 102 elderly patients with irreversible intertrochanteric fractures treated in our hospital between January 2018 and January 2020 were selected and divided into the control group (n=51) and the observation group (n=51) according to the random number table method. The control group was treated with open reduction and internal fixation, and the study group was treated with percutaneous prying PFNA closed reduction and internal fixation technology. The two groups were followed up for 2 months after operation. The operation-related indicators, the hip joint excellent rate and complications between the two groups were compared, the levels of serum NE and AngⅡ before and after 1 day after operation between the two groups were compared; the score of Harris 1, 2 months after operation were calculated.
Results The operation time (46±4) min, incision length (5.0± 0.5) cm and hospital stay (11.1±1.6) d in the study group were shorter than that in the control group [(78±6) min; (12.6±1.4) cm; (12.9 ±2.8) d, t=31.137, 37.955, 4.039, P<0.05)], intraoperative blood loss (132±27) mL was less than the control group [(156±25) mL, t=4.715, P<0.05)]. The excellent and good hip joint rate in the study group at 1 and 2 months after surgery were 80.39% and 94.12%, which were higher than the control group at 60.79% and 68.63% (t=8.421, 9.314, P<0.05). Compared with preoperation, the score of Harris in both groups showed a gradually increasing trend at 1 and 2 months post-operation (F=11.537, 15.458, P<0.05), and the study group were higher than the control group at 1 and 2 months after operation (F=5.824, 3.736, P<0.05). Compared with preoperation, the levels of serum NE and AngⅡ increased in the two groups after 1 day (study group, t=19.396, 12.789, control group, t=41.450, 17.143, P<0.05), and the study group were lower than the control group (t=22.705, 4.683, P<0.05). The incidence of complications in the study group was 5.88%, which was lower than the 11.76% in the control group (χ2=4.126, P<0.05).
Conclusion Percutaneous prying PFNA closed reduction internal fixation technology can improve the surgical indicators of elderly patients with irreversible intertrochanteric fractures, and can reduce the serum NE and Ang Ⅱ levels of patients and reduce fracture injuries, thereby helping to enhance the hip function of patients, improve the excellent rate of hip joints, and have higher safety.
