Carrying angle, or cubital angle defined as the acute angle formed by the median axis of the arm when forearm is in fully extended and supinated position. This angle changes with skelatal growth and maturity. This study was aimed to investigate the correlation of carrying angle with bi-acromial diameter and bi-acromial diameter/bi-trochanteric diameter in our healthy young adult population. This was a cross-sectional study that included 400 (204 male,196 female) young adult students selected from Cukurova University aged between 18-25 years (mean +/- standard deviation of females: 20.11 +/- 2.05 years; mean +/- standard deviation of males: 20.45 +/- 1.82 years) which originated from different cities in Turkey. After recording demographic data, carrying angle, forearm length, ann length, bi-trochanteric diameter and bi-acromial diameter were measured by using nonelastic tape measure, pelvimeter and manuel goniometer. In addition, body mass index and bi-acromial diameter/bi-trochanteric diameter were calculated for each participants. The mean values of body height and weight were in following respectively for both genders: 178.53 +/- 6.40 cm (male), 163.88 +/- 5.73 cm (female); 74.89 +/- 10.81 kg (male), 57.56 +/- 8.61 kg (female). Whereas on dominant arm this angle was as in males 9.77 degrees +/- 2.82 degrees and 13.94 degrees +/- 3.97 in females. The mean value of the carrying angle on nondominant ann in males was 9.85 degrees +/- 2.95 degrees and 14.03 degrees +/- 4.08 degrees in females. The mean carrying angle was 9.81 degrees +/- 2.82 degrees in males and 13.99 degrees +/- 3.97 degrees in females. There are linear relationship between the carrying angle and height r=-0.474, p<0.001, bi-acromial diameter (r=-0.490, p<0.001), bi-acromial diameteribi-trochanteric diameter (r=-0.449, p<0.001), forearm length (r=-0.366, p<0.001) and arm length (r=-0.273, p<0.001). We believe that the reference values of carrying angle will help the clinician in the management of elbow displacements, fractures, prosthetic design and diagnosis of epicondylar diseases.
