Comparative study of balloon kyphoplasty with unilateral versus bilateral approach in osteoporotic vertebral compression fractures.

This study analyses the radiological and clinical results according to the two techniques of unilateral and bilateral balloon kyphoplasty in osteoporotic vertebral compression fractures. Fifty-two patients with osteoporotic vertebral compression fractures occurring at the thoracolumbar junction were enrolled in this study. All patients were classified into two groups; group I was treated with a unilateral approach and group II with a bilateral approach. The Cobb angle was measured each time to evaluate the kyphotic angle during the pre- and post-operative periods and at last follow-up, and a 10-point visual analog scale for pain was recorded at the same time. We found that the bilateral approach had a greater advantage in the reduction of kyphosis and the loss of reduction was less than the unilateral approach for the treatment of osteoporotic vertebral compression fractures.
