Percutaneous Balloon Kyphoplasty for the compression Vertebral fractures: one year outcome in height restoration and correction/ improvement of Kyphosis

Sandra Sungailaite

Objective

The objective of the study is to look for the effectiveness of percutaneous balloon kyphoplasty in the restoration of Vertebral body height and correction or improvement of kyphosis.

Design- Retrospective study.

Subjects- Patients with Vertebral column wedge compression fracture.

Methods

A retrospective  analysis of  112 patients presented  over 4  years and 4 months with 200  symptomatic  wedge vertebral compression fractures treated by Percutaneous  balloon Kyphoplasty. To assess  degree of kyphosis  and height restoration of  fractured  vertebral  body , we reviewed  digital radiographs  and measured  pre  and post cobb and wedge angle for  kyphosis ; Ratios of the height of the anterior border, centre, and posterior borders of the collapsed vertebra to the height at the posterior border of an adjacent normal vertebral body were measured in  immediate post-operative period  and next follow up   and also  calculated  gain of  height in anterior , middles and posterior  part of  Vertebral body, percentage of lost height restoration.

 Results

The height of vertebral body height increases after kyphoplasty. The anterior body height improved 10% in first post-operative and subsequently 14% in next follow up . Middle and posterior heights also revealed 13%, 17% and 9% , 11% improvement  respectively.  The restoration percentage for the  lost vertebral height were 34 % for anterior  border in the first  Post operative  period , 49%  in the next  out patient follow up; 46%  and 60% for middle border, and  62%, 76% for posterior  border of vertebral  height. The mean reduction in kyphotic angle was 3.1 degree, and 2.4 degree in wedge angle, restoration percentages for the kyphosis angle and wedge angle were 11.3% and 18.7%, respectively.

Conclusions: 

Kyphoplasty result in improvement of height of vertebral body and angular deformity.
