The primary objective of this study was to evaluate randomized controlled trials (RCTs) that have reported the effects of teriparatide on bone-healing in osteoporotic hip and pelvic bone fractures to determine the efficacy of teriparatide in lowering the rate of treatment failure. A total of 2,809 studies were identified using a comprehensive literature search (MEDLINE [n=1,061], Embase [n=1,395], and Cochrane Library n=353]). Five RCTs were included in the final analysis. Treatment failure rates at the last follow-up of osteoporotic hip and pelvic bone fractures between the teriparatide and control groups was the primary outcome. Treatment failure was defined as non-union, varus collapse of the proximal fragment, perforation of the lag screw, and any revision in cases due to mechanical failure of the implant during the follow-up period. The number of treatment failures in the teriparatide and placebo groups were 11.0% (n=20 out of 181) and 17.6% (n=36 out of 205), respectively. Although the rate of treatment failure in the teriparatide group was lower than that in the control group, this difference was not significant (odds ratio, 0.81 [95% confidence interval, 0.42-1.53]; P=0.16; I =42%). This meta-analysis did not identify any significant differences in the rate of treatment failure between the teriparatide and control groups at final follow-up. Based on these results, we believe that there is a lack of evidence to confirm efficacy of teriparatide in reducing treatment failures in osteoporotic hip and pelvic bone fractures.
