Asymmetric sacrotuberous and sacrospinous ligament
Journal Title: International Journal of Anatomical Variations - Year 2017, Vol 10, Issue 4
Abstract
Aim: To describe a case of medial asymmetry in the sacrotuberous/sacrospinous ligament complex (SSTL). Methods: Description of the anatomical findings in a cadaver with an asymmetrical SSTL and comparison to five anatomically normal cadaveric dissections. Results: Marked asymmetry with an atypical proximal origin and cord-like SSTL is described and contrasted to the more typical fan-shaped ligament complex. No vascular perforators traversed the SSTL in the atypical case and the vessels were relatively protected during SSTL release. Conclusion: Significance variance and asymmetry within the SSTL can occur. Surgeons should be aware of this phenomenon and consider anatomical variations when performing a peri-sacral dissection.

Multiple variations in vertebrobasilar system: A cadaveric study
The intracranial parts of the vertebral arteries (VAs), basilar artery (BA) and their branches together form the vertebrobasilar system (VBS). Numerous anomalies have been seen in VBS, which are usually benign. Many auth...
Morphological study on mitral valve chordae tendineae in the hearts of human fetuses
BACKGROUND: Mitral valve chordae tendineae (CTs) are filaments of connective tissue that attach the mitral valves to the papillary muscles, which contract and cause tension on these chordae, so as not to allow separation...
Bilateral presence of a variant subscapularis muscle
We describe the presence of an accessory subscapularis muscle observed bilaterally in a human anatomy laboratory. The muscle originated from the mid-region of the lateral subscapularis inserting into the proximal humerus...
Nonrotation of the intestine: embryological and clinical correlation
A defect in the rotation of midgut to assemble the parts of the gut in the normal anatomical location results in nonrotation. This is a very rare variation with an incidence of 1:500. This case is reported for its extrem...
Medical illustration in anatomical variations
The history of anatomic variations is as old as the history of anatomy. Vesalius, considered the initiator of the modern age of the anatomy, has done many dissections on human body. Since anatomical variations are not co...
