English Abstract:

  【Abstract】 Objectives: To Summarize the complications of percutaneous kyphoplasty(PKP) for osteoporotic vertebral compression fractures(OVCFs), and to investigate its causes and prevention. Methods: From September 2004 to June 2009, the PKP was performed on 115 OVCFs patients. There were 24 males and 91 females, with an average age of 68 years(range, 52-83 years). 83 cases had single vertebra, 24 cases had double vertebrae, 5 cases had 3 vertebrae, 2 cases had 4 vertebrae, 1 case had 5 vertebrae involved. Preoperative MRI STIR sequence was used to determine injured segment, including 1 in T6, 2 in T7, 2 in T8, 8 in T9, 9 in T10, 24 in T11, 44 in T12, 41 in L1, 18 in L2, 5 in L3, 3 in L4, 2 in L5. The complications and causes were analyzed. Results: A total of 21 cases was noted complications, with the rate of occurrence of 18.2%. Bone cement leakage was noted in 13 cases(11.3%); intraoperative balloon rupture in 3 cases(2.6%); perforation into the spinal canal in 2 cases(1.7%); loss of height in 2 cases(1.7%); postoperative vertebral collapse 1 cases(0.9%). No severe neurological deficit, epidural hematoma or pulmonary embolism was noted. Conclusions: The complications associated with PKP treatment include bone cement leakage, balloon rupture, perforation into the spinal canal, vertebral height loss, postoperative vertebral collapse, which should be managed by corresponding preventions.
