Accessory muscles around the superior radioulnar joint: a morphological study.

摘要: During anatomical dissections on 36 human elbow joints, we observed the presence of three muscles around superior radioulnar joint usually neglected by classical literature, lateral tensor muscle annular ligament (with an incidence 16.6%), medial (11.1%) and accessory supinator (16.6%). We could not establish any association between subject handedness sidedness these aberrant muscles, neither found a predominance in or gender. Furthermore, did notice significant related to occupation specifically heavy labor occupations. On contrary be more common non-laborers, which supports assumption that variants constitute rather genetic than epigenetic traits. The knowledge such facilitate surgeon operating region better interpret supernumerary muscular bundles operative field.
