Significant Change

Background:Dual energy X-ray absoprtiometry is the reference method to mesure bone mineral density (1). Loss of bone mineral density is significant if it exceeds the least significant change. The threshold value used in general population is 0,03 g/cm2 (2). Patients with obesity are known for having a higher bone mineral density due to metabolism and physiopathology characteristics (3,4).Objectives:The aim of our study was to determine the least significant change in bone densitometry in patients with obesity.Methods:We conducted an interventionnal study in 120 patients with obesity who performed a bone densitometry. We measured twice the bone mineral density at the lumbar spine, the femoral neck and the total hip in the same time (5,6). We determined the least significant change in bone densitometry from each pair of measurements, using the Bland and Altman method. We also determined the least significant change in bone densitometry according to each stage of obesity.Results:The least significant change in bone densitometry in patients with obesity is 0,046g/cm2 at the lumbar spine, 0.069 g/cm2 at the femoral neck and 0.06 g/cm2 at the total hip.Conclusion:The least significant change in bone densitometry in patients with obesity is higher than in general population. These results may improve DXA interpretation in this specific population, and may personnalize their medical care.References:[1]Lees B, Stevenson JC.

Abstract INTRODUCTION Diminished bone mineral density (BMD) places patients at increased risk for complications from lumbar fusion procedures. Dual-energy X-Ray absorptiometry (DEXA) scanners have been used as the gold standard in measuring BMD. More recently, various studies have suggested that Hounsfield unit measurements from computed tomography (CT) scans may be more accurate. METHODS After obtaining IRB approval, we retrospectively reviewed all patients aged 18 and older who underwent lumbar fusion procedures between 01/01/2010 and 12/31/2016 at our institution. We used linear regression to assess for a correlation between CT Hounsfield units and DEXA t scores. Student's t-test was used to compare CT Hounsfield units, lumbar spine t score and hip t scores for patients with and without pseudoarthrosis as well as those with and without hardware failure. RESULTS A total of 167 patients with lumbar fusion procedures met inclusion criteria. Ages ranged 24 to 88 yr old with a mean of 64. Using linear regression there was no correlation between CT Hounsfield units and Dexa T scores. There was no difference between the groups with respect to CT Hounsfield units or DEXA T scores when comparing patients with and without pseudoarthrosis and when comparing patients with or without hardware failure. CONCLUSION Diminished BMD is an important factor to consider when contemplating lumbar spine fusion procedures as this has been associated with increased risk of hardware failure or pseudoarthrosis. Traditionally DEXA scans and more recently CT Hounsfield units have used to screen patients for decreased BMD, however, in this relatively large retrospective series we found that neither correlate well with complications from lumbar spine fusion procedures. CT and DEXA scans may not be as reliable as once thought in assessing BMD.
