ABSTRACT
Objective To study the clinical outcome of percutaneous vertebroplasty (PVP) for the s disease who had been suffering severe back pain even after conservative therapy for months were treated with PVP. Their preoperative CT images indicated nonunion of factures and "vacuum signs". Dynamic X-ray films demonstrated formation of pseudoarthrosis in the involved vertebral bodies in some eases. Their back pain was evaluated with visual analogue scale (VAS). Their preoperative and postoperative VAS scores and radiological indexes were compared. Results The mean VAS scores were 7.0±1.2 preoperatively, but 3.1±1.5 at the follow-up (P < 0.05) . The height of anterior margin of involved vertebral body was (2.1±0.3) cm pre-operatively, but (2.3±0.2) cm at the follow-up (P < 0.05). The ratio of anterior margin height to posterior margin height of the involved vertebral body was 0. 67±0. 10, but 0.84±0.08 at the follow-up (P<0.05), The focal kyphosis angle was 27.3°± 6.4° preoperatively but 20.7°±5.0° at the follow-up (P < 0.05). No pulmonary embolisms or neurological injuries happened. Conclusion PVP is an effective method for anterior margin of the involved vertebral body partially, and decrease the focal kyphosis.
