Torsion Humerus

Die Torsion des Humerus beschreibt die physiologische Verdrehung des Humerus in seiner Längsachse. Zur Torsionsbestimmung sind verschiedene klinische und radiologische Messverfahren beschrieben. Die computertomographische Messung stellt derzeit die standardmäßige Methode dar. Hierbei orientiert sich der Winkel zum einen an der Humeruskopf- und an der transepikondylären Achse und wird als Retroversion beschrieben. Die Retroversion des Humerus wird in der Literatur mit Werten zwischen 10. torsion in over 600 human humeri as well as in those of about 40 anthropoids and 100 various mammals and birds. He came to the conclusion that a true torsion of the humerus exists and placed its value in the adult human at 164 degrees. Later, Le Damany (1903, 1906) reported his observations on humeral torsion in man and many lower forms. Le Daman 1.5 Knochen der freien Gliedmaße: Torsion des Humerus.

Humeral Torsion as a Risk Factor for Shoulder and Elbow Injury in Professional Baseball Pitchers. The results of this study show a contrast in dominant humeral retrotorsion between pitchers who suffered shoulder and elbow injuries compared with those without an injury Er beträgt bei Neugeborenen etwa 60° (Torsion des Humerus). Durch Abflachung des Thorax in sagittaler Richtung verändert sich die Stellung des Schulterblatts. Dieser Änderung muss der Humeruskopf folgen, sodass der Torsionswinkel bei Erwachsenen nur noch etwa 20° beträgt The torsion of the humerus describes the physiological rotation of the humerus around its longitudinal axis. Various clinical and radiological methods for measurement have been described. The computed tomography method is currently the gold standard. The angle between the humeral head axis and the transepicondylar axis is measured. This angle is called retroversion

  2. DEVELOPMENTAL DYNAMICS provides a focus for communication among developmental biologists who study the progressive and dynamic emergence of form and function during embryonic development. The journal is an international forum for the exchange of novel and substantive information on mechanisms that control development. We seek manuscripts presenting work done at all levels of biological.
  3. When humeral shaft or supracondylar fractures are treated, or when rotational deformities of the humerus are corrected, this method of measurement is very practical, because the humeral torsion of the unaffected side provides a standard for the individual. With this method of measuring humeral torsion, we also found that cubitus varus deformity after supracondylar fracture in children is caused not only by an increase in varus angulation but also by internal rotation of the distal fragment
  4. Humeral torsion describes the angular difference between the orientation of the proximal humeral head and the axis of the elbow at the distal humerus. 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 distall
  5. The right humerus of lB1 has relatively limited degree of humeral torsion according to morwood et al. (2005). The humeral torsion is approximately 110°, which is less than in large bodied apes.
  6. La torsion de l'humérus est un de ces cas : cet os, chez l'Homme, est tordu, tordu visiblement sur son axe et d'environ i 80 degrés, et cela toutefois sans qu'aucune force de torsion se soit exercée à aucune époque sur la substance de l'organe individuel que nous avons sous les yeux. En effet, ainsi que nous l'a fait remarquer l'érainent naturaliste de Montpellier, cetie disposition se montre déjà au moment où l'os fait son apparition première chez le fœtus, et en quelque sorte.
  7. The torsion of the humerus describes the physiological rotation of the humerus around its longitudinal axis. Various clinical and radiological methods for measurement have been described. The computed tomography method is currently the gold standard. The angle between the humeral head axis and the transepicondylar axis is measured. This angle is called retroversion. Values of retroversion vary.

The Torsion of The Humerus

humerus was identified as the most accurate method for assessing the precision of torsion during MIS for humeral shaft fractures. The transepicondylar axis line is more internally rotated than the intertubercular sulcus tangent line. The mean angle was measured to be 41.1 degrees. Conclusions: The axis of the distal humeral condyles is internally rotated by approximately 41.1 degrees compared. Fractures of the humeral shaft are common, as they account for 10% of long-bone fractures and 3-5% of all fractures [ 1 , 2 ].

Th e mean angle of torsion was found to be 62.8 ° wit h a range of 40 ° (minimal value 42 °, maxima l. A further (ontogenetic) torsion is superimposed upon the phylogenetic one in man which increases from birth until the proximal epiphysial cartilage of the humerus disappears and bony fusion occurs. There is a distinct correlation between the calculated strength of humeral rotator muscles inserting above and below the proximal epiphysis; this suggests that they provide the forces involved in.

Our investigation revealed that humeral torsion is inversely proportional to weight, length, and mid-shaft circumference of the humerus. This study established the existence of bilateral asymmetries in the humeri of all the geographical regions investigated with more asymmetry observed in the male compared with the female. Several studies have established a relationship between morphological.
