Comparative Clinical Results of Vertebroplasty Using Jamshidi® Needle and Bone Void Filler for Acute Vertebral Compression Fractures

Abstract

ObjectivePercutaneous 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.MethodsOne 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.ResultsIn 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).ConclusionFor 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.

Percutaneous screw placement in the lumbar spine with a modified guidance technique based on 3D CT navigation system

“…Several reports of navigated percutaneous PS placement in the lumbar spine with the use of CT have been published. Jamshidi navigated needles are widely used for the placement of guidewires into the pedicles and vertebral bodies in this procedure as well as in vertebroplasty (30,67). According to our technique, cannulation of the pedicles for the placement of the guidewires is performed through a navigated drill guide.…”
