Abstract

Background Context

Percutaneous vertebroplasty (PVP) and kyphoplasty (KP) are minimally invasive treatment options for VCFs due to malignancy.

Purpose

To perform a systematic review evaluating the effectiveness and safety of vertebral augmentation for malignant vertebral compression fractures (VCFs).

Study Design

Systematic Review

Study Sample

Studies on PVP or KP for VCFs in patients with malignant spinal lesions.

Outcome Measures

Visual Analog Scale (VAS) for pain, Oswestry Disability Index (ODI), Karnofsky Performance Score (KPS), and complications were extracted from eligible studies.

Methods

Using PRISMA guidelines, studies published between January 1, 2000 and January 3, 2018 were identified by combining the results of a report by Health Quality Ontario with an updated literature search.

Results

The review identified 2 RCTs, 16 prospective studies, 44 retrospective studies, and 25 case series for a patient sample size of 3426. At the earliest follow-up, pain improved from 7.48 to 3.00 with PVP, and from 7.05 to 2.96 with KP. ODI improved from 74.68 to 17.73 with PVP, and from 66.02 to 34.73 with KP. KPS improved from 66.99 to 80.28. Cement leakage was seen in 37.9% and 13.6% of patients treated with PVP and KP respectively. Symptomatic complications (N=43) were rare.

Conclusions

This review showed clinically relevant improvements in pain, ODI, and KPS in patients with VCFs due to malignancy treated with either PVP or KP. Cement leakage is common, but rarely symptomatic. PVP and KP are safe and effective palliative procedures for painful VCFs in patients with malignant spinal lesions.
