Minimally Invasive Treatments for Osteoporotic Vertebral Compression Fractures
Summary
Osteoporotic vertebral compression fractures (OVCFs) represent a growing global health challenge as an ageing population drives increased fracture incidence, morbidity and health-care costs. Minimally invasive vertebral augmentation techniques have become the mainstay of treatment for patients with persistent pain and functional limitation. Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) both aim to stabilise the fractured vertebral body by introducing polymethylmethacrylate bone cement under image guidance. PKP adds a balloon tamp to partially restore vertebral height and correct kyphotic deformity before cement delivery. These procedures typically provide rapid pain relief, early mobilisation and reduced reliance on systemic analgesia. However, complications such as cement leakage, adjacent-level fractures and loss of restored height remain a concern. In response, innovative augmentation devices—such as expandable implants, screw-cement hybrids and novel cavity-forming systems—have been developed to enhance load sharing, reduce cement extravasation and improve anatomic restoration. Biomechanical modelling and finite-element simulations increasingly inform implant design and surgical planning. Concurrently, meta-analyses and large observational studies have clarified patient-related risk factors, including low bone mineral density, advanced age and cement leakage, that predispose to recurrent or adjacent fractures. Collectively, these advances point towards a stratified approach in which device selection and perioperative management are personalised to optimise long-term vertebral stability and quality of life.
