Comprehensive Review of Osteogenesis Imperfecta: Current Treatments and Future Innovations.

Abstract

Osteogenesis imperfecta (OI) is a rare genetic disorder characterized by bone fragility due to reduced bone quality, often accompanied by low bone mass, recurrent fractures, hearing loss, skeletal abnormalities, and short stature. Pathogenic variants in over 20 genes lead to clinical and genetic variability in OI, resulting in diverse symptoms and severity. Current management involves a multidisciplinary approach, including antiresorptive medications, physiotherapy, occupational therapy, and orthopedic surgery, which provide symptomatic relief but no cure. Advancements in gene therapy technologies and stem cell therapies offer promising prospects for long-lasting or permanent solutions. This review provides a comprehensive overview of OI's classification, pathogenesis, and current treatment options. It also explores emerging biotechnologies for stem cells and gene-targeted therapies in OI. The potential of these innovative therapies and their clinical implementation challenges are evaluated, focusing on their imminent success in treating bone disorders.
