title: The relationship between the carrying angle and the distal extent of the 2nd and 4th fingertips.
abstract: The angle towards the lateral side between the arm and forearm when the  forearm is in full extension and supination is defined as the carrying angle. It is  well known that the 2nd finger is longer in women whereas the 4th finger is  longer in men, due to in-utero hormonal effects. In the present study, the  relationship between the carrying angle and the distal extent of the 2nd and  4th fingertips is studied. The findings reveal that the carrying angle was greater  both in left and right sides in women than in men. In addition, while the distal  extent of the 2nd fingertips was longer in women, the 4th fingertip was longer  in men. There was a moderately positive correlation between the carrying angle  and the distal fingertip lengths. Therefore, it could be suggested that the  morphometric factors play role on the distal extent of the fingertips other than  the hormonal effects.
