Detailed MRI–Anatomic Study of the Lateral Epicondyle of the Elbow and Its Tendinous and Ligamentous Attachments in Cadavers
AJR. American journal of roentgenology, 2010Co-Authors: Cristiane S. Zoner, Florian M. Buck, Fabiano Cardoso, Ramon Gheno, Debra Trudell, Tori D. Randall, Donald ResnickAbstract:OBJECTIVE. The objective of our study was to document discrete bone landmarks in the lateral epicondyle of the humerus that represent the “footprints” of those tendons and ligaments that attach to it using MRI–anatomic correlation in cadavers.MATERIALS AND METHODS. Thirty-three dried humeral specimens were inspected to document bone landmarks in the lateral epicondyle. MRI with anatomic correlation was performed in 10 additional cadaveric elbows. The locations of the tendinous and ligamentous attachments to the lateral epicondyle were determined with respect to the same osseous landmarks.RESULTS. The surface of the lateral epicondyle ranged from a flat surface to a surface with up to six discrete landmarks: superior tubercle, anterior tubercle, posterior tubercle, Intertubercular Sulcus, rough area surrounding the tubercles, and epicondylar ridge. The radial collateral ligament attached to the superior aspect of the Intertubercular Sulcus and inferior aspect of the superior tubercle and was indistinguisha...

Intertubercular Sulcus of the humerus as an indicator of handedness and humeral length
Clinical anatomy (New York N.Y.), 1995Co-Authors: Selvakumar Vettivel, G. Chandi, Inbam Indrasingh, K.g. Selvaraj, S. M. ChandiAbstract:Measurements of the maximum width and depth of the Intertubercular Sulcus (ITS), angles of the medial and lateral walls with the floor of the ITS, as well as the length of the humerus in 100 right and 100 left matched, unpaired dry humeri of 100 adults were statistically analyzed. Since 90–95% of the general population is right handed, on the basis of altered size of the dimensions of the right ITS relative to the left, it is proposed that greater width and smaller angles of the medial and lateral walls of the ITS of one side are indicative of handedness on that side. Handedness can further be deduced by the presence of a

Handedness can further be deduced by the presence of a <50° angle of the medial wall and of a supratubercular ridge of Meyer on that side. The length of the humerus correlated with the width and depth of the ITS (P < 0.001). Regression equations of the length of the humerus on width, depth, as well as width and depth of the ITS have been derived. © 1995 WiIey-Liss, Inc.

Variations in the Intertubercular Sulcus of the humerus related to handedness
Journal of Anatomy, 1992Co-Authors: Selvakumar Vettivel, G. Chandi, Inbam Indrasingh, S. M. ChandiAbstract:Measurements of the maximum width and depth of the Intertubercular Sulcus (ITS) and the angles formed by the medial and lateral walls of the ITS with the plane of its floor were recorded in 200 adult human humeri, 100 each from the right and left sides. The ITS was more often wider and its medial wall formed a more acute angle with the plane of its floor in right-sided humeri. A supratubercular ridge on the humerus was present more frequently on the right than on the left. The presence of this ridge is probably more necessary on the right to prevent medial displacement of the long head of the biceps tendon from the ITS. The greater thrust exerted by the taut tendon of the long head of the biceps in the upper limb that is used preferentially probably induces structural differences in the ITS.

Correlation between the retroversion of the humeral head and the orientation of the Intertubercular Sulcus: a CT scan anatomical study
Surgical and Radiologic Anatomy, 2015Co-Authors: Daphne Guenoun, Thomas Le Corroller, Aude Lagier, Vanessa Pauly, Pierre ChampsaurAbstract:The purpose was to study the anatomy of the humeral head, more specifically the retroversion of the humeral head and the orientation of the Intertubercular Sulcus, using CT scan, and to make correlations between those two entities of the proximal humerus. Sixty dry adult humeri from an osteological collection underwent CT scan from the proximal to the distal extremity. The measurements obtained by CT-reformation were recorded by two independent radiologists. We determined the humeral head axis, the transepicondylar axis, the retroversion of the humeral head, and the orientation of the Intertubercular Sulcus (ITS). Statistical analysis using SPSS determined the Pearson correlation coefficient. The CT scan measurements were similar to those in the literature, and thus allowed us to validate CT scan assessment. Statistical analysis showed a significant reverse correlation [the coefficient of correlation was -0.37 (p = 0.004)] between the retroversion of the humeral head and the orientation of the Intertubercular Sulcus: the more the retroversion of the humeral head increases, the more the angle of the orientation of the ITS decreases. To the best of our knowledge, this reverse correlation between the retroversion of the humeral head and the orientation of the Intertubercular Sulcus has never been described. This new anatomical data might be helpful for orthopedic surgery.

Handedness identification from Intertubercular Sulcus of the humerus by discriminant function analysis
Journal of Clinical Forensic Medicine, 1999Co-Authors: K.g. Selvaraj, Inbam Indrasingh, Vettivel Selvakuhmar, G. ChandiAbstract:The accurate determination of skeletal handedness is a critical requirement in physical anthropology and forensic science. To differentiate handedness, discriminant function analysis is applied using the parameters of right and left Intertubercular sulci. A total of 200 matched unpaired adult humeri (100 right and 100 left), collected from the Department of Anatomy, were used to measure four parameters of the Intertubercular Sulcus namely, width (X ), depth (X ), 1 2 angle of medial wall (X ) and angle of lateral wall (X ) and to note the presence of supratubercular 3 4 ridge of Meyer (X ). The discriminant function obtained with the significant variables, angle of 5 medial wall (X ), angle of lateral wall (X ) and presence of the supratubercular Meyer (X ) 3 4 5 is:Y 5 0.093X 1 0.056X 1 0.775X 2 13.46. The accuracy of correct classification using the 3 4 5 discriminant function is 89% which is the best starting point for handedness determination approach. The methodology of using discriminant function can be crucial for medicolegal jurisprudence. 1998 Elsevier Science Ireland Ltd. All rights reserved.

To differentiate handedness, discriminant function analysis is applied using the parameters of right and left Intertubercular sulci. A total of 200 matched unpaired adult humeri (100 right and 100 left), collected from the Department of Anatomy, were used to measure four parameters of the Intertubercular Sulcus namely, width ( X 1 ), depth ( X 2 ), angle of medial wall ( X 3 ) and angle of lateral wall ( X 4 ) and to note the presence of supratubercular ridge of Meyer ( X 5 ). The discriminant function obtained with the significant variables, angle of medial wall ( X 3 ), angle of lateral wall ( X 4 ) and presence of the supratubercular Meyer ( X 5 ) is: Y =0.093 X 3 +0.056 X 4 +0.775 X 5 −13.46. The accuracy of correct classification using the discriminant function is 89% which is the best starting point for handedness determination approach.
