81 Absence of anatomical posterior triangle of neck: Clinical and embryological perspective S. Singh Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, India Aim of the study was to report an uncommon case of unilateral absence of posterior triangle, portray its embryological and phylogenetic basis and to discuss its clinical implications. Formalin fixed adult male Indian cadaver was used for the study. This finding was noted during routine dissection of head and neck region for undergraduate medical teaching programme. The geometry of the left posterior triangle was obscured due to the failure of sternocleidomastoid and the trapezius muscles to exist as two separate entities. These two muscles were seen as a single unified sheet. However, an unfamiliar oval gap was observed in its postero-superior portion. Knowledge of such muscular variant augments the anatomical literature on one hand and provides a clinical insight for head and neck surgeons, radiologists, anesthetists and physicians in their clinical practice on the other hand. Conflicts of interest The author has none to declare. http://dx.doi.org/10.1016/j.jasi.2016.08.388 82 Duplication of the great saphenous vein: A case report Ashwini Kudopa L.N.M.C. Bhopal, Madhya Pradesh, India Course of great saphenous vein was traced in the subcutaneous tissue. Skin was removed along the course of great saphenous vein from its termination to its beginning in the foot. The study presents a case of partial duplication of great saphenous vein. During routine undergraduate dissection of the lower limb we came across a case of partial duplication of great saphenous vein on the left lower limb of female cadaver. Knowledge of duplication of great saphenous vein is necessary, as if missed can be a cause of recurrence of varicose vein after surgery.

vertebral arches are involved leaving the spinal cord intact. The bony defect is covered by skin. Usually no neurological defects occur. Total spina bifida occulta of sacrum is considered rare. During routine osteology demonstration for 1st year M.B.B.S. students we came across the presence of spina bifida occulta in sacrum. Usually no neurological defects occur. Total spina bifida occulta of sacrum is considered rare.

The objective of the study is to report a case of unusual communication of musculocutaneous nerve with median nerve. During routine dissection on a male cadaver aged about 60 yrs in the Department of Anatomy, RIMS, Imphal, Manipur, unusual bilateral communication of musculocutaneous nerve with median nerve was observed. On the right side, the lateral cord of brachial plexus gave a small lateral root for the Median nerve and at the same level the musculocutaneous nerve also originated, entered the anterior compartment of the arm by piercing the Coracobrachialis muscle, gave a separate branch each to Biceps brachii and Brachialis muscles and gave a large abnormal communication to the Median nerve in the arm. On the left side, the musculocutenous nerve instead of piercing the Coracobrachialis, it passed in front of the muscle and gave a separate branch to all the 3 muscles of the front of the arm. It also gave abnormal communication to the Median nerve in the arm. Anatomical knowledge of such variations will be of utmost importance in clinical practice.
