Epub 2016 Oct 1. West EA, Knowles NK, Athwal GS, Ferreira LM. Angle of inclination=130-150 degrees 2. The study consisted of 36 healthy adults (18 males and 18 females aged between 20 and 68 years). [Results] The average angle of the glenoid version was -4.26° on the throwing side and -1.18° on the non-throwing side. The average difference in angle determination between the two methods was 0.9°; the maximum difference was 3°. Rev Chir Orthop Reparatrice Appar Mot. Determining Torsion Angle of Humerus Head Using MRI Method - PubMed Considering intersocietal anatomic differences, our study may shed light on torsion angle for Turkey by determining mean torsion angle value. Humeral torsion and retroversion in the literature: A reply to Larson Angle of inclination Angle of torsion 33. Results. So the humerus must be retroverted 15 degrees. Recent clinical studies have revived this topic by linking patterns of humeral torsion to … This site needs JavaScript to work properly. Anthropological interest in humeral torsion has a long history, and several functional explanations for observed variation in the orientation of the humeral head have been proposed. The identified associations include altered glenoid version [1], decreased humeral torsion [2], and variations in proximal humeral and acromial morphologies [3]. Shoulder Elbow. [Humeral retroversion and shoulder prosthesis]. Players had statistically significant (P<.001) side-to-side difference in humeral head version, with an average of 10.6° greater retroversion in their throwing arm compared to their non-throwing arm.A significant side-to-side difference was not observed in the control group (average difference, 2.3°; P = .197). Results: In general, increased humeral torsion angle was positively associated with increased IR ROM and decreased ER ROM ( Fig. v�����2T������ӱ'U\��-�fh� �0+�]��G`{�m?���i�(���ȣ���zɋ��z�S%���`i������a�: �Ctv� {�cY�������6��9���0��x����ğ�g��r"e}вv����UTʲ컸�C����e��C$��u��@Hɖ��0B���UxM�X���:3]n�*�U�(E�-i�o���'�E���g�~����ns���|��O]��ܥJQ�R�[�u� �~0 ���' 1995;81(5):419-27.

Relationship between humeral torsion and injury in professional baseball pitchers. J Clin Diagn Res. [Three-dimensional geometry of the proximal humerus and rotator cuff attachment and its utilization in shoulder arthroplasty]. The gender of the bones was also determined... Observations: The humeral torsion is greater in the male than in the female and greater on right side than left side humeri possibly because most individuals are right handed. 2018; 28 (4):678–684. 1995. The humeral torsion angle (HTA) was calculated using axial MRI images. The differences of humeral torsion angle and the glenohumeral rotation angles between young right-handed and left-handed pitchers.  |  This angle is measured at the intersection of two lines: one that evenly bisects the articular surface of the humeral head proximally, and the second being the transepicondylar line distally .

Epub 2017 Jun 6. Our own studies on this subject started in 1976 (13-16). RESULTS: Average humeral torsion angles of 27±10° (dominant side) and 31±10° (non-dominant side) were demonstrated in this elite swimming cohort. Despite a wide variation in the humeral torsion angle among the specimens from the different cadavera, the angle varied little between the two normal humeri of the same individual (mean side-to … SS �+�9Q���O� ��O���l����o�S���yQ ��}�e��v)�W�b�°���k��0�ּ�J�Jxwx���B�V��JX݁u�ۇ����t�݊9��$��}����I�a� ���8�,��)dc�p�5�r�x N�O ��Φ�Sq�p�P�kw|�9X�r�W7����U��W�8�n2�P�������Dy/$��Le"mf� �H�'PE����B�0�Eʿ��|���,�~ RESULTS Average humeral torsion angles of 27±10° (dominant side) and 31±10° (non-dominant side) were demonstrated in this elite swimming cohort. doi: 10.7860/JCDR/2016/22121.8672. The angle of humeral torsion may be determined in living subjects by computerised axial tomography, in conjunction with immobilisation of the arm on a rigid board. The angle formed by a line drawn through the center of the longitudinal axis of the neck and head of the humerus meeting a line drawn along the transverse axis of the condyles, when the base is viewed from above, looking straight down from above the head of the humerus; the normal angle of retroversion of the humerus is 20 to 40 degrees. NIH Moreover, this study indicated that HTA can be successfully measured using MRI. Epub 2013 Jun 20. Determining Angle of Humeral Torsion Using Image Software Technique. Moreover, this study indicated that HTA can be successfully measured using MRI. Mean humeral curvature was 20.4 ± 4.4° (range, 9.6° to 30.5°). 2016 Oct;10(10):AC06-AC09.
