A Diagnostic Tool for Healthcare Professionals. Dilation of aorta progressive if diameter is . Thirty-six patients with the phenotypic features of Marfan's syndrome (arachnodactyly, abnormal ratio of arm span to height, ligamentous laxity, and tall stature) were evaluated and classified into three groups. The second way to calculate the ape index is to subtract height from the wingspan. By contrast, Epstein reports that the average NBA player has an arms-to-height ratio of 1.06-to-1, "greater than the diagnostic criteria for Marfan syndrome, a disorder of the body's . The .

Marfanoid (or Marfanoid habitus) is a constellation of symptoms resembling those of Marfan syndrome, including long limbs, with an arm span that is at least 1.03 of the height of the individual, and a crowded oral maxilla, sometimes with a high arch in the palate, arachnodactyly, and hyperlaxity. Use of the arm-span to height ratio as a criterion for Marfan syndrome in Aboriginal Australians: Diagnostically challenging . The value of their arm span to height ratio was slightly below the criteria (>1.05), but these ratios were considered to be high for Japanese, as the incidence of an enlarged arm span to height . 1. At standing AP and LL X-rays of the spine, scoliosis > 20 or thoracolumbar kyphosis, measured by Cobb method, was observed in 37 patients (25.3%). A arm span greater than height is thought to be advantageous in some sports such as swimming, as longer arms may give greater propulsion. Typically, a person's arm span should be less than their body height; an increased arm span to body height ratio of >1.05 is considered a positive sign for Marfan syndrome. A typical ratio is 1, as identified by the Roman writer, architect and engineer Vitruvius prior to 15 BC. The above case is representative of Marfan Syndrome (MFS), and given the incidence, it is important for general pediatricians to be aware of the common features and management. The use of a correction factor for the estimated of height with arm span has been practiced for several decades due to reports by various studies involving predominantly Caucasian adult populations, that the mean arm span to height ratio for their population is 1.03 for men and 1.01 for women (Hepper et al. This ratio normally equal to 1, is around 1.03 in 80% of patients and becomes a criterion from 1.05 .
