Vertebroplasty

Jensen et al. in 1997 presented 29 patients (47 compression fractures) who underwent vertebro-plasty after failing conservative treatment (7). Twenty-six patients out of 29 (90%) had reduction

of pain within 24 hours of the procedure. Barr et al. reported on 47 patients (84 compression fractures) who underwent vertebroplasty three weeks to three months after the onset of symptoms. Twenty-four of 47 (63%) patients had complete pain relief, 12 (32%) had moderate pain relief, and only 1 (5%) had no pain relief. The most contemporary study is from Evans et al. who reported a multicenter study that evaluated 467 cases of vertebroplasty with a follow-up three-part subjective scale system that included (i) pain relief (a 10-point scale), (ii) activities of daily living, and (iii) abnormal ambulation. Evaluation of preoperative to postoperative status showed a mean drop in the pain scale of 9 out of 10 to 3.2 out of 10. In regard to activities of daily living, only 9% of patients reported having no significant problem preoperatively, which increased to 67% postoperatively. Preoperatively 98% of patients had an abnormal gait-pattern ambulation compared to 28% postoperatively (8).
