Several techniques have been developed for kyphosis secondary to osteoporotic vertebral compression fractures during the last 2 decades. Techniques of vertebral body augmentation have been developed in an effort to treat these refractory cases. The high pressure injection of low viscosity of (PMMA) has potential risk for neural compromise and pulmonary embolism by uncontrolled leakage. Therefore, balloon kyphoplasty and vertebroplasty using a large cannula low pressure injection of PMMA in a high viscosity state has been introduced. Percutaneous kyphoplasty (PKP) is a recently developed, minimally invasive surgical treatment for OVCF. complications for balloon kyphoplasty include non-target PMMA embolization, adjacent vertebral body or rib fracture and infection.
