Kummell's Disease Managed by Percutaneous Vertebroplasty / 대한척추외과학회지

ABSTRACT

STUDY DESIGN: Prospective study about fourteen consecutive patients with Kummell's disease who were treated by percutaneous vertebroplasty with bone cement. OBJECTIVES: To evaluate the results of percutaneous vertebroplasty using bone cement in the treatment of Kummell's disease. SUMMARY OF LITERATURE REVIEW Kummell's disease is a rarely reported, poorly documented, and poorly understood phenomenon. It is associated with intravertebral vacuum phenomenon and clinically manifested by painful kyphosis. The treatment of the disease had been conservative or surgical reconstruction, but both conservative and operative treatment were not satisfactory in some patients. MATERIALS AND METHODS: A review was conducted of 14 patients with 18 vertebrae treated with percutaneous vertebroplasty from June 1999 to May 2000. They had posttraumatic vertebral collapse or Kummell's disease and had failed medical therapy. Immediate and long-term pain response and complications of percutaneous vertebroplasty with bone cement were evaluated. RESULTS: All patients reported complete relief of pain within the first 24 hours. Ten(71.5%) were evaluated as excellent; three(21.4%), good; one(7.1%), fair until 3 months postoperatively. Eight(57.2%) were evaluated as excellent; four(28.6%), good; fair(7.1%), one; poor(7.1%), one at final follow-up. Five(35.7%) patients had cement extrusion into the disc, paravertebral vessels and epidural space without significant systemic symptoms. CONCLUSIONS: For patients with posttraumatic vertebral collapse or Kummell's disease, percutaneous vertebroplasty technique using bone cement would be a minimally invasive treatment option to achieve immediate relief of pain and stabilization without significant side effects.
