Abstract: Objective To investigate the correlation between elevation modes of lower limbs and deep venous thrombosis (DVT) in the elderly patients with hip fracture, and to decrease the risk of lower limb DVT in the patients. Methods The clinical data of 105 elderly patients with hip fracture in the department of orthopedics from June 2018 to June 2019 were retrospectively analyzed. The patients receiving postoperative elevation with fowler position were enrolled in group A (33 cases), the patients receiving triangle decubitus elevation were enrolled in group B (5 cases), and the patients receiving trapezoidal decubitus elevation were enrolled in group C (37 cases). The incidence of lower limb DVT was recorded and compared among the three groups after intervention. Results Seven to ten days after surgery, the color Doppler ultrasound of lower limbs showed that the incidence of lower limb DVT in group B was 34.29% (12/35), compared with 9.09% (3/33) in group A and 8.11% (3/37) in group C, with significant difference (χ² =10.277, P=0.006). Conclusions The postoperative application of trapezoidal position and fowler position in the elderly patients with hip fracture can promote the venous velocity of lower limbs, thus decreasing the risk of lower limb DVT. The elevation mode of triangle position can not effectively prevent lower limb DVT. Therefore, it is necessary to avoid raising the affected limb with a soft pillow under the knee.
