Follow-up on Percutaneous Vertebroplasty Using PMMA in Osteoporotic Patients

Abstract

We reviewed the follow-up findings of patients who received percutaneous vertebroplasty, in order to understand the effects of vertebroplasty on following issues: pain relief, height restoration, wedge deformity correction, kyphosis correction, and other radiological findings found in follow up studies, such as new fractures. Generally, the pain relieving effect after vertebroplasty is long lasting except when new fracture occurred, or presence of other problems that caused the back pain. Height restoration and wedge deformity correction last for more than one year. The effect of kyphosis angle correction may vanish one year after procedure due to occurrence of new fracture in adjacent vertebral bodies.

Augmentation of failed human vertebrae with critical un-contained lytic defect restores their structural competence under functional loading: An experimental study

“…Augmentation significantly decreased the kyphotic angle of the failed vertebral bodies, a finding previously reported for osteoporotic vertebrae in vitro (Alkalay et al, 2008;Belkof et al, 2000Belkof et al, , 2001 and in clinical radiographic follow-up studies (McKiernan et al, 2003;Teng et al, 2003Teng et al, , 2006. However, in agreement with in-vitro (Alkalay et al, 2008) and clinical (Dublin et al, 2005;McKiernan et al, 2003;Voggenreiter, 2005) studies, the change in the dimensions of the vertebral bodies was reversed to pre-augmentation levels once the vertebrae were re-tested under load.…”

Surgical management of lower limb radiculopathy following acute singe-level osteoporotic vertebral fracture of lower lumbar spine in geriatric patient: a retrospective study

“…Next, these patients underwent posterior decompression and instrumentation, in which one patient died of postoperative intracranial hemorrhage. The refracture rate of the cemented vertebrae after PVP was as high as 63% in patients with osteoporosis [ 20 ], especially in those cases who had an over-restoration of the anterior height of vertebral body [ 21 ]. An adequate restoration of the posterior height of vertebral body is important to decrease the refracture rate of the cemented vertebra [ 21 ].…”

An adequate restoration of the posterior height of vertebral body is important to decrease the refracture rate of the cemented vertebra [ 21 ]. Revision surgery should be avoided as much as possible considering the poor general conditions of such elderly patients.…”

Establishment of a risk prediction model for residual low back pain in thoracolumbar osteoporotic vertebral compression fractures after percutaneous kyphoplasty

“…The anterior vertebral height (AVH) and Cobb angle of the fractured vertebral body were measured prior to the surgical procedure and one day after surgery. The AVH of the fractured vertebra and the posterior border height of the adjacent normal vertebral body were measured on lateral radiographs using the method described by Teng et al [ 15 ]. Due to the different presentation sizes of the radiographs, the vertebral body height was expressed as relative magnitude: (AVH of the fractured vertebral body /mean of the heights of adjacent posterior vertebral body) × 100% (Fig.…”
