Effectiveness of unilateral percutaneous vertebroplasty for acute traumatic non-osteoporotic compression vertebral...

Although vertebroplasty is a well-known treatment for osteoporotic and neoplastic compression fractures, there is limited evidence to support its use in traumatic compression fractures without osteoporotic degeneration. The purpose of this study was to evaluate the correlation of kyphosis and wedge angles with pain relief and functional outcome after percutaneous vertebroplasty. 38 patients who harbored acute traumatic non-osteoporotic compression vertebral fractures without neurological complications refractory to at least 5 days of conservative treatment were included in this study. Follow-up evaluations included pain (assessed with the visual analog scale) and medication use. Functional outcome was measured using Oswestry low back pain disability questionnaire. Cobb angles, Gardner angles and kyphotic angles were measured on the full-spine radiographs preoperatively and postoperatively. The axial pain visual analog scale score (8.05 ± 1.23 pre-op vs 1.18 ± 1.09 post-op, P < .05) and The Oswestry low back pain disability questionnaire score (33.45 ± 6.97 pre-op vs 4.47 ± 2.41 post-op, P < .05). The Cobb's angle (19.66° ± 8.68° pre-op vs 15.08° ± 7.51° post-op, P < .05), the Gardner's angle (17.72° ± 6.52° pre-op vs 14.13° ± 7.13° post-op, P < .05) and the kyphotic angle (17.51° ± 5.8° pre-op vs 8.81° ± 4.14°post-op, P < .05) were significantly reduced postoperatively therefore, local kyphosis was markedly restored after vertebroplasty. Our findings show that vertebroplasty for patients with traumatic spinal compression fractures reduces pain, improves mobility, reduces the need for painkillers, and significantly affects kyphotic angles.
