nameDXA Humerus [Z-score] Bone density
descriptionMeasuring the bone density of the humerus helps determine the best approach to treatment for patients being considered for shoulder surgery and those with humeral fractures. Patients needing shoulder surgery are at higher risk of local osteoporosis due to lack of mechanical stimulation, and general osteoporosis is a common risk factor for proximal humerus fractures in patients aged 65 and over. Determining the presence of osteoporosis pre-operatively can help decide if different repair techniques and hardware, such as threaded anchors, should be used. [PMID: 25027108]

Fully-Specified Name

componentViews for bone density
propertyZscore  =  Z Score
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemUpper extremity>Humerus
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
