Osteoporotic spinal deformity: a biomechanical rationale for the clinical consequences and treatment of vertebral body compression fractures.
This review article develops a biomechanical rationale for the clinical consequences and treatment of osteoporotic vertebral body compression fracture. In patients with osteoporotic vertebral fractures and spinal deformity, altered spinal biomechanics and global spinal imbalance are important factors in the increased morbidity and mortality reported in this population. Severe spinal deformity impairs physical functioning, health, and quality of life. The spinal deformity itself, independent of pain, is a significant cause of disability. Spinal deformity is also an independent risk factor for hip fracture. Treatments directed at osteoporotic vertebral compression fractures should ideally address spinal deformity as well as pain. Balloon kyphoplasty, the minimally invasive technique of reduction and internal fixation of osteopenic vertebral body compression fractures that addresses pain and spinal deformity, is discussed.
