Percutaneous vertebroplasty (PVP) is an effective treatment modality for management of osteoporotic compression fracture. However physicians sometimes have problems of high pressure in cement delivery and cement leakage when using Jamshidi® needle (JN). Bone void filler (BVF) has larger lumen which may possibly diminish these problems. This study aims to compare the radiologic and clinical outcome of JN and BVF for PVP.
One hundred twenty-eight patients were treated with PVP for osteoporotic vertebral compression fracture (VCF) where 46 patients underwent PVP with JN needle and 82 patients with BVF. Radiologic outcome such as kyphotic angle and vertebral body height (VBH) and clinical outcome such as visual analog scale (VAS) scores were measured after treatment in both groups.
In JN PVP group, mean of 3.26 cc of polymethylmethacrylate (PMMA) were injected and 4.07 cc in BVF PVP group (p<0.001). For radiologic outcome, no significant difference in kyphotic angle reduction was observed between two groups. Cement leakage developed in 6 patients using JN PVP group and 2 patients using BVF group (p=0.025). No significant difference in improvement of VAS score was observed between JN and BVF PVP groups (p=0.43).
For the treatment of osteoporotic VCF, usage of BVF for PVP may increase injected volume of cement, easily control the depth and direction of PMMA which may reduce cement leakage. However, improvement of VAS score did not show difference between two groups. Usage of BVF for PVP may be an alternative to JN PVP in selected cases.

To analyze the effect of vertebroplasty on costal pain which develops following osteoporotic thoracic compression fractures (OTCFs).
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 imaging and chart reviews.
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.
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.
