We hypothesize that a change in the anatomical angle of the hamatum curvature changes the carpal tunnel volume. To prove our hypothesis, we used a mathematical simulation model considering the carpal tunnel as a truncated cone. We reviewed the wrist CT scans of 91 adults (&gt;18 years of age), including 51 men and 40 women. We measured the angle of the hamatum curvature in the CT scans. We measured cross-sectional areas at the outlet of the carpal tunnel at the level of the trapezium and hook of hamate (<jats:italic>r<\/jats:italic>1) and at the inlet at the level of the scaphoid and pisiform (<jats:italic>r<\/jats:italic>2) and the length (<jats:italic>h<\/jats:italic>) of the carpal tunnel. We attempted to calculate the effect of 2 degree by 2-degree changes in the angle of the hamatum curvature between the angles of 98\u00b0 and 140\u00b0 on the carpal tunnel volume. The mean angle of the hook of hamatum of the subjects was 122.55\u00b0\u2009\u00b1\u20098.20\u00b0 (range, 97.20\u00b0\u2009\u2212\u2009139.31\u00b0). No suitable cutoff point was found for the angle values. There was no difference between the gender groups according to the angle value. The data clearly show that there is a high correlation between carpal tunnel volume and the angle of hamatum curvature. The results of our study emphasize the importance of taking into account the anatomical features of the hamatum bone, especially the angle of curvature, which may play a predisposing role in idiopathic carpal tunnel syndrome.<\/jats:p>","DOI":"10.1155\/2020\/7582181","type":"journal-article","created":{"date-parts":[[2020,3,10]],"date-time":"2020-03-10T23:38:56Z","timestamp":1583883536000},"page":"1-6","source":"Crossref","is-referenced-by-count":0,"title":["The
