Spinal fractures constitute one of the most prevalent injuries to the human skeletal system with approximately 1.4 million fractures per annum worldwide. Treatments for these injuries have evolved from simple bed rest through to the intricacy of modern minimally invasive surgery. Balloon kyphoplasty is one such treatment that uses a balloon to decompress collapsed vertebra, followed by injection of bone cement to stabilise the fracture. Recent research has correlated a ‘halo’ feature on kyphoplasty patient x-rays with a 78% re-collapse rate. The present work documents a new method of mechanical analysis to evaluate balloon kyphoplasty and explores alterations to current …

Balloon Kyphoplasty uses an inflatable bone tamp and cement augmentation to repair vertebral compression fractures. A recent clinical study observed a 78% re-collapse rate in patients showing a radiolucent phenomenon at the bone-cement interface following Kyphoplasty. Two experimental studies showed significant height loss following Balloon Kyphoplasty under cyclical loads. The present study investigates the alteration in load angle corresponding to this height loss and its effect on load transfer to the bone-cement interface. A validated finite element model of a human thoracolumbar spine was segmented into a single L1 vertebral body and modified to replicate bilateral Balloon Kyphoplasty. Cement was …
