AbstractObjective To investigate the effects of different lower limb length balancing strategies on the postoperative lower limb length and hip joint function after artificial femoral head replacement. Methods A retrospective analysis was conducted on 78 patients who underwent artificial femoral head replacement in Anhui Provincial Corps Hospital of Chinese People's Armed Police Force between January 2020 and December 2022. According to the order of admission time, 26 patients were grouped together, namely Group A (Shuck test method), Group B (improved head neck ratio method), and Group C (Kirschner wneedle marking positioning method). The The unequal length of lower limbs ( LLD) value and Harris score of hip joint were compared before and after treatment in 3 groups, and the general surgical condition, postoperative gait and complications were compared in 3 groups. Results After treatment, the LLD value and Harris score of the hip joint and the postoperative gait speed, single leg support time, and stride frequency in groups B and C were better than those in group A (P<0.05), while there was no statistically significant difference between groups B and C (P>0.05). There were no statistically significant differences between the three groups in terms of intraoperative bleeding volume, surgical time, hospital stay, postoperative VAS score, and hospital expenses. The incidence of postoperative complications in Group B was the lowest, which was better than that in Groups A and C (P<0.05), and there was no statistically significant difference between Groups A and C (P>0.05). Conclusions Both the improved head to neck ratio method and the Kirschner needle marking positioning method can effectively reduce the LLD value after artificial femoral head replacement, which is beneficial to the recovery of postoperative gait and hip joint function, and is superior to the traditional Shuck test method. The modified head to neck ratio method is a non-invasive method, simple and easy to implement, with fewer postoperative complications, and is more suitable for elderly patients.
