Abstract
INTRODUCTION: There were higher rates of revision, complication, non-union, delayed union, and poorer functional outcomes reported in super-aged patients of undisplaced femoral neck fractures treated with internal fixation. Therefore, we designed this randomized comparative study aiming to compare the effectiveness and long-term follow-up results of hemiarthroplasty (HA) with that of multiple cannulated screws (MCS). MATERIALS AND METHODS:Eligible participants were randomly assigned into two groups for different methods of operation (hemiarthroplasty group and internal fixation group). The related indexes and data of two groups were collected for comparative analysis during the average follow-up period of 38.68 ± 28.24 months. RESULTS: There were only two patients performed reoperation in HA group, and the reoperation rate of HA group (5.41%, 2/37) was significantly lower than that of IF group (21.4%, 9/41) (P value = 0.000). The comparison of survival curves for reoperation showed significant differences between two groups (P value = 0.031).The results of Cox proportional hazards model suggested that only operation method significantly affected the occurrence of reoperation (P value = 0.049). The results of survival analysis showed that there was no significant difference in survival time between two groups (P value = 0.682). And in the Cox proportional hazards model, only age significantly affected the occurrence of death (P value = 0.000). The average Harris scores of two groups were all above 75 points, and there was no significant difference in Harris scores between the two groups (P value greater than 0.05). But in the early term follow-up, the excellent and good rate of hip joint function in HA group was significantly higher than that in IF group (P value less than 0.05). CONCLUSIONS:Hemiarthroplasty with less postoperative complications, low reoperation rate and better function recovery in early stage provide a good choice for the treatment of super-aged patients with nondisplaced femoral neck fracture.
