Objective: To evaluate the clinical outcome of percutaneous kyphoplasty in treating vertebral compression fractures.
Methods: From October 2008 to May 2010,41 patients with osteoporotic vertebral compression fractures were treated with percutaneous kyphoplasty. There were 10 males and 31 females, ranging in age from 61 to 83 years, with an average of 67.5 years. Fracture site was from T9 to L4 including 65 vertebral bodies. Clinical symptom was lumbar and back pain to affect orthobiosis. The pain, height of vertebral body, Cobb angle, function of daily activities were analyzed by VAS sore, imaging data, Oswestry score before and after operation.
Results: All operations were successful and no severe complications were found. Bone cement leakage occurred in 7 vertebrae, but no clinical sympton. All lumbago obtained obviously anesis after operation. All patients were followed up from 7 to 26 months with an average of 14 months. Preoperative, postoperative and at final follow-up, VAS score was 8.38 +/- 0.60, 2.45 +/- 0.38, 2.53 +/- 0.36, respectively; Oswestry score was 40.00 +/- 1.16, 17.00 +/- 2.11, 15.00 +/- 1.41, respectively; height of vertebral body was (14.64 +/- 1.30), (25.11 +/- 1.12), (23.16 +/- 1.14) mm, respectively; Cobb angle was (30.17 +/- 1.45) degrees, (12.10 +/- 1.37) degrees, (14.31 +/- 0.51) degrees, respectively. There was significant difference between postoperative and preoperative, and between at final follow-up and preoperative (P<0.05). There was no significant difference between final follow-up and postoperative (P>0.05).
Conclusion: Percutaneous kyphoplasty is effective for treatment of senile osteoporotic vertebral compression fractures, which can expeditiously relieve pain and effectively recover height of vertebral body and kyphosis Cobb angle, has advantages of minimal trauma and good security.
