Clinical and Demographic Characteristics of Patients Who Were Treated with Kyphoplasty Due to Osteoporotic Fracture

Abstract

Objective: The aim of this study is to determine the demographic and clinical characteristics of patients who underwent kyphoplasty due to osteoporotic fractures. Materials and Methods: This retrospective study included 55 patients who underwent kyphoplasty due to osteoporotic fracture between the years 2011 and 2014. The patients divided into two groups according to their ages (under/over 65 years), and divided into three groups according to fracture regions (T10 and above; between T11-L1; L2 and under). Thus the age and gender distributions of the patients were made. Resting pain scores of all patients were determined by using visual analog scale (VAS) and daily life activities by Oswetry Disability Index (ODI) before and in the first month of treatment. Results: Seventeen of the all patients were male (30.9%) and 38 were female (69.1%), with a mean age of 69.9±8.7 years (between 50-88 ages). 90% of the patients older than 65 years had fracture in T11 and below. In 45.5% of all patients, the fracture was in the T11-L1 (thoracolomber junction) region. Resting VAS and ODI scores significantly improved from 8.7±1.5 to 2.1±1.2 and 44.7±7.2 to 15.4±3.5 respectively in the first month after kyphoplasty (p<0.05). Kyphoplasty material extravasated to the disc space in 7 (12.7%) patients and in 4 (7.3%) patients to cerebrospinal fluid. Conclusion: Osteoporotic fractures affect patients over 65 years of age and are frequently occur in the thoracolumbar junction and lower vertebras. Kyphoplasty is a minimally invasive treatment option to relieve pain and to improve functional status.
