Trial Outcomes & Findings for Evaluation of Outcomes for Quality of Life and Activities of Daily Living for BKP in the Treatment of VCFs (NCT NCT01871519)

NCT ID: NCT01871519

Last Updated: 2017-03-29

Results Overview

Back pain was measured using NRS. Patients rated their back pain on a scale from 0-10, with a score of 0 representing "no pain" and a score of 10 representing "pain as bad as it could be."

Participant Flow

A total of 354 subjects were enrolled in this study. Among them, 350 subjects had BKP surgery and 4 subjects were not treated with BKP. Two of the non-treated subjects voluntarily withdrew from the study and 2 subjects were lost-to-follow-up before surgery.

Balloon Kyphoplasty
This group of patients were treated with balloon kyphoplasty in the treatment of painful, acute VCFs associated with either osteoporosis or cancer. Balloon kyphoplasty: The devices to be used in this study are intended for percutaneous balloon kyphoplasty (BKP) and consist of the Kyphon® bone access needles and cannulae, inflatable bone tamps, curettes, polymethyl methacrylate bone cement (PMMA) bone cements, and bone filler devices.

For subjects with cancer, the Karnofsky performance scale was used for rating subject activities of daily living.The Karnofsky performance scale rates a subject on an 11-step scale from 0 (dead) to 100 (normal, no complaints, no evidence of disease), and a score of 70 is a clinically meaningful threshold for self-care.

To some extent missing data were from unanswered questions, missing image, etc.

AHRP (Absolute height restored as percent) was the amount of height restored in the vertebral body expressed as a percent of estimated pre-fracture (EP) height. Measurements were assessed at anterior, medial, and posterior locations on the vertebral body.

The number analyzed was based on the observed data and there were missing data stemming mostly from subject drop-out or lost-to-follow-ups. To some extent missing data were from unanswered questions, missing image, etc.

The vertebral body kyphosis angle (VBA) was defined as the angle formed by lines drawn parallel to the caudal and cranial fractured vertebral body endplates.

Balloon Kyphoplasty
n=490 Treated levels
This group of patients were treated with balloon kyphoplasty in the treatment of painful, acute VCFs associated with either osteoporosis or cancer. Balloon kyphoplasty: The devices to be used in this study are intended for percutaneous balloon kyphoplasty (BKP) and consist of the Kyphon® bone access needles and cannulae, inflatable bone tamps, curettes, polymethyl methacrylate bone cement (PMMA) bone cements, and bone filler devices.

Population: A total of 490 treated levels in 344 subjects were included in LCA analysis. The number analyzed was based on the observed data and there were missing data stemming mostly from subject drop-out or lost-to-follow-ups. To some extent missing data were from unanswered questions, missing image, etc.

The local Cobb angle (LCA) was defined as the angle formed by lines drawn parallel to the superior endplate of the vertebral body above and the inferior endplate of the vertebral body below.

Neurological functions were assessed preoperatively and postoperatively. Each of the individual functions was comprised of a number of elements. Investigators evaluated whether observations in each function category was normal or abnormal, and documentation of abnormal findings were required for each element in that function. Success for each component was defined as maintenance or improvement from preoperative for all elements. Success for overall neurologic status was defined as successful in all components.
