Kyphoplasty, Patient Selection and Potential Complications

Kyphoplasty was first performed in 1998. It may be defined as inserting an inflatable balloon within the vertebral body through a trocar. The cavity formed in the vertebral body is filled with bone cement. Kyphoplasty was developed to cope with high rates of cement leakage by vertebroplasty and the inability of vertebroplasty to correct fracture deformity. Creation of a cavity within the vertebral body decreases the potential for cement leakage as well as creating a high density zone in the vertebral body. Evaluation of patients for vertebral augmentation should identify those likely to benefit from vertebral augmentation, as well as screen for contraindications. Primary indication for kyphoplasty is painful or progressive osteoporotic or osteolytic compression fractures, that are refractory to conservative medical therapy. Contraindications are Local or systemic infection, coagulopathy, cardiopulmonary insufficiency, height loss of the vertebral body greater than 80% of the pre-fracture height, true burst fractures, and fractures associated with neurological findings. Some of potential complications are hemorrhage, infection, cement extrusion or leakage (paravertebral, intravenous, or into the spinal canal), and transient radiculopathy.
