Treatment
We conclude that early detection of LRP5 mutations is important for initiation of treatment of reduced bone density in the patients and their carrier relatives. [ncbi.nlm.nih.gov]
However, bisphosphonates cannot be considered as an ideal treatment for treatment of OPPG in some patients. Streeten et al. reported fractures in three of nine OPPG patients with low-normal hip areal BMD after treatment with bisphosphonates (12). [brieflands.com]
