Abstract

Abstract: BACKGROUND: Hip replacement has become the main treatment for femoral neck fracture in the elderly at present, but there is no simple, effective or reproducible method to reduce the incidence of unequal length of lower limbs.
OBJECTIVE: To investigate the effectiveness of head-neck ratio in balancing the difference of lower extremity length in femoral neck fracture replacement.
METHODS: From January 2017 to March 2019, 132 aged patients undergoing unilateral artificial femoral head replacement for femoral neck fracture were selected as the research object. From January 2017 to February 2018, 68 cases were treated by traditional method of equilibrium of lower limb length, known as the traditional group. From March 2018 to March 2019, 64 patients with head and neck for spell equilibrium in lower limb length were included in the improved group. The operation time, hospital stay, postoperative double lower limbs length difference, the last follow-up function Harris hip score and complications after surgery were selected for retrospective analysis in both groups.
RESULTS AND CONCLUSION: (1) All patients were followed up for 6-20 months. (2) There were no statistically significant differences between the modified group and the traditional group in operation time, hospital stay, and postoperative complications (P > 0.05), but the improved group (4.56±3.07) mm had a significant advantage over the traditional group (6.09±3.31) mm in the balanced length of lower limbs, and the difference between the two groups was statistically significant (P < 0.05). (3) At the last follow-up, Harris score of hip function in the improved group (92.36±3.35) points was higher than that in the traditional group (91.09±3.41) points, and the difference between the two groups was statistically significant (P < 0.05). (4) These results indicate that artificial femoral head replacement for elderly patients with unilateral femoral neck fracture using head-neck ratio is simple and effective. It is effective in balancing the unequal length of lower limbs after surgery and promoting the recovery of hip function.
