Parathyroid Hormone in the Management of Pelvic Fragility Fractures: A Systematic Review and Meta-Analysis
Abstract
Background: Fragility fractures of the pelvis (FFPs) are increasingly prevalent given ageing populations. Conservative management is often primarily utilised due to its initial minimal displacement and the high risks of surgery in this vulnerable population. However, this can lead to rapid deconditioning, especially with non-weight-bearing protocols. Parathyroid hormone (PTH), as a bone anabolic agent, has the potential to improve clinical and radiological outcomes in FFPs, but the evidence remains limited. Methods: A systematic review and meta-analysis following PRISMA guidelines was undertaken. Database search results were independently screened by two authors, and data were extracted. The primary outcome measure was time to fracture healing as assessed by imaging, with the secondary outcome measure of pain levels (VAS/NRS). Results: There were 1230 articles screened, and 893 unique results identified. Six studies were included in the final analysis. These compared the use of PTH and its analogues with standard care, placebo, or sacroplasty. The findings suggest that PTH may accelerate fracture healing and reduce pain in this patient population, although evidence is limited and at high risk of bias. Conclusions: Treatment with PTH may improve bone healing and visual analogue pain scores, although the evidence is limited. There may be a benefit from adjunctive PTH treatment for patients with FFPs; however, larger methodologically robust studies are required to confirm this.
