The Effect of Vertebroplasty on Costal Pain Related to Osteoporotic Thoracic Compression Fractures in Elderly Patients

Abstract

Objective: To analyze the effect of vertebroplasty on costal pain which develops following osteoporotic thoracic compre-ssion fractures (OTCFs). Methods: The authors reviewed the medical records of 35 patients who underwent vertebral augmentation for the treatment of OTCFs over a five year period. The patients were divided into two groups: the costalgia group included patientswho had costal pain after a vertebral fracture and the non-costalgia group included patients without costalgia. To evaluate the effect of vertebroplasty on costal pain and factors related to costal pain, several factors including: vertebral body fracture type, pedicle injury, bone mineral density, the fracture level and clinical outcome were confirmed with magnetic resonance imag-ing and chart reviews. Results: Among 35 patients, ten patients (28.6%) complained of costal pain with back pain. Only five of the ten patients (50%) had improved costal pain after a vertebroplasty. In the remaining 5 patients, the costal pain was improved through the use of medication including pain killers or a costal block during the follow-up period. Although the incidence of wedge deformity in the costal group was low (10%), there was no significant relationship to the incidence of costal pain statistically. Pedicle injury, bone mineral density and the fracture level had no significant relation to costal pain. Conclusion: The patients with wedge type, OTCFs may have a low incidence of costal pain as compared to those patients with bi-concave and crush deformities. The vertebroplasty effect on costal pain may not be effective. Therefore, before doing vertebroplasty, the surgeon should advise patients of this potential outcome in those treated for OTCFs.
