Treatment of osteoporotic vertebral fractures

Osteoporosis is a public health problem that is contributing to an increasing number of osteoporotic vertebral fractures. The aim of this lecture is to summarize the current state of knowledge about osteoporotic fractures by answering five questions. 1/How does the spine typically age and how is osteoporosis diagnosed? Various normal aging processes will gradually modify the vertebral column (static, dynamic, bone quality). Osteoporosis is diagnosed through a DEXA scan. 2/How is an osteoporotic fracture evaluated clinically and radiologically? Magnetic resonance imaging is the preferred modality for making the diagnosis and selecting the most appropriate treatment. 3/What are the treatment options for an osteoporotic fracture? The options are conservative treatment, conventional surgery, and minimally invasive techniques (cementoplasty, percutaneous instrumentation). 4/Which fractures should be treated, and which technique should be used? The choice is clear when neurological deficits are present, although the indications are less firm when there is no deficit. The treatment can be conservative (back brace) if the fracture is non-displaced and minimally painful, vertebroplasty if the fracture is painful and shows hyperintensity on T2-STIR sequences, vertebral expansion if the radiological deformity worsens along with symptoms. 5/What are the technical challenges and complications related to the presence of osteoporosis when treating vertebral fractures surgically? The reduced bone stock increases the risk of poor implant hold and postoperative mechanical complications (adjacent fracture, junctional kyphosis). Technical solutions have been developed (augmented screw fixation, transitional zone) to limit their impact. It is essential to know and master these techniques, and their indications. Treatment of the osteoporosis itself is crucial. Level of evidence V; Expert opinion.
