Material used in veerbroplasty is :
Correct Answer: Polymethyl methacrylate
Description: Polymethyl methacrylate [Ref: Harrison 17/e p112; Veebroplasty and kyphoplasty are interventional radiologic procedures for the treatment of the intense pain refractory to medical management or bracing caused by veebral compression fracture associated with osteoporosis, tumors, and trauma. Veebroplasty and kyphoplasty involve intraosseous injection of acrylic cement- polymethyl methacrylate under local anesthesia and fluoroscopic guidance. Pain reduction or elimination is immediate, and the risk of complications is low. Neither veebroplasty nor kyphoplasty are intended for the treatment of interveebral disc disease or ahritis. Veebroplasty may also be applied prophylactically to an at-risk veebra between 2 other abnormal veebrae. Veebroplasty does not restore the height of the compressed veebral body. A related procedure, kyphoplasty, is intended to restore lost height by inflating a balloon pump within and between the fracture fragments prior to the infusion of the cement. Both procedures result in similar relief of pain due to veebral compression fractures. The risks of the procedure are low and include extravastion of cement into the epidural space causing myelopathy, or fatal pulmonary embolism from extension of cement into paraspinous veins.
