Figure 4 Comparative of hip flexion and abduction range of motion between the two groups after surgery (°, mean ± SD). A: Bucking; B: Outreach. Contrasted with the control group, the research group has greater degree of hip flexion and abduction after surgery. P < 0.05 means that the control group and the research group at different time points (24 h, 36 h, 48 h, 7 d, 15 d after the surgery) hip flexion contrasted with abduction activity, the variance was significant difference.
