  Fig. 3. Postoperative change in the levels of hemoglobin, total protein, and albumin and white blood cell count. The levels of hemoglobin (Fig. 3A), total protein (Fig. 3B), and albumin (Fig. 3C) and white blood cell count (Fig. 3D) were measured on postoperative days 1, 3, 5, and 7. To follow the patient’s recovery over time, the changes from postoperative days 1 to 3, 3 to 5, and 5 to 7 were analyzed. The variation in the levels of hemoglobin, total protein, and albumin in the HA group on postoperative days 3 to 5 was negative; however, the results were positive in the PFNA group. During this period, the variation in hemoglobin level was − 4.20 ± 8.47 g/L for the HA group and 2.19 ± 11.36 g/L for the PFNA group (Fig. 3A, P* < 0.05); the variation in the total protein level was − 0.19 ± 5.07 g/L for the HA group and 1.31 ± 4.59 g/L for the PFNA group; the variation in the albumin level was − 0.14 ± 4.27 g/L for the HA group and 0.65 ± 3.23 for the PFNA group; and the variation in the white blood cell count was − 2.10 ± 2.08 × 107/L for the HA group and − 0.12 ± 2.72 × 107/L for the PFNA group (Fig. 3D, P* < 0.05). On postoperative days 5 to 7, the variations in the levels of hemoglobin,…

Patients were divided into subgroups according to age at surgery, and the resultant scores were as follows: there was a significant difference between the HA and PFNA groups in the subgroup of patients aged older than 90 years (Fig. 4A, P* < 0.05).
