Abstract

INTRODUCTION: Most previous reports indicate that traditional bilateral kyphoplasty improves patient function and restores height of collapsed vertebral bodies, but limited data about the effects of unilateral kyphoplasty on clinical and radiological outcome are available.

MATERIAL AND METHODS: One hundred five patients were treated by unilateral kyphoplasty between January 2004 and December 2006. These patients underwent 105 operations to treat 132 vertebral compression fractures between T8 and L5. Sagittal alignment was analyzed from standing radiographs. Clinical outcomes were determined by comparison of preoperative and postoperative data from patient-reported index (visual analogue pain scale score). Radiographs were assessed as to percent vertebral collapse, vertebral height restoration and local kyphosis correction.

RESULTS: Mean length of follow-up was 15.3 months (range 3-36 months); improved height 2.3 and 4.0 mm in the anterior and medial columns, respectively (P > 0.05); Cobb angle increased 3.0 degrees (P < 0.05), visual analogue pain scale score improved from 8.7 +/- 1.4 before surgery to 2.3 +/- 0.9 (P < 0.05); no adverse medical or procedural complications; 6.8% (9/132) cement leakage rate.

CONCLUSION: Unilateral transpedicular kyphoplasty improves physical function, reduces pain, and may correct kyphotic deformity associated with vertebral compression fractures. This result shows comparable to traditional bilateral kyphoplasty procedure.
