Abstract:

Objective

The meta-analysis was performed to determine whether the early use of the anti-resorptive drugs would affect bone union.

Methods

We searched MEDLINE, EMBASE, CENTRAL and CBM for the related studies from each database inception until December 19, 2020. The inclusion criteria were all relevant clinical randomized controlled studies that studied the relationship between the anti-resorptive drugs and bone union. We assessed the quality of the included studies with version 5.2 of the Cochrane risk-of-bias tool, and the software for data synthesis was Review Manager 5.4.1. The effect measure was risk ratio (RR) with 95% confidence interval (CI), the Mantel-Haenszel method and the fixed effect model were used to analyze data.

Results

25 studies met the inclusion criteria, 18 studies were included in the meta-analysis, including 3, 421 people, the total bone union RR=1.013(95% CI: 0.994, 1.032, P=0.198). In the sensitivity analysis of excluding 11 non-low-risk studies, RR=1.008 (95% CI: 0.987, 1.029, P=0.475). In the subgroup analysis, the limb fracture population(9 studies, 2, 891 persons), RR= 1.009 (95% CI: 0.989, 1.029, P=0.399); the spinal fusion population (9 studies, 530 persons), RR=1.034 (95% CI: 0.979, 1.091, P=0.230), the osteoporotic population (13 studies, 749 persons), RR=1.038 (95% CI: 0.993, 1.086, P=0.103); the internal fixation surgery population (15 studies, 2,967 persons), RR=1.005 (95% CI: 0.989, 1.021, P=0.540). The results of each analysis included an invalid value of 1, that is, the early use of the anti-resorptive drugs in bone repair did not affect bone union.

Conclusions

In general, the early application of the anti-resorptive drugs in bone repair does not affect bone union. Among them, no matter the limb fracture patients or the spinal fusion patients, whether the osteoporotic patients, or the patients undergoing internal fixation surgery, the use of the anti-resorptive drugs in the early stage of bone repair to prevent secondary osteoporosis fracture does not affect bone union. Therefore, for patients suitable for anti-osteoporosis treatment, it is recommended to start anti-osteoporosis treatment immediately after fracture.
