Deltoid Muscle , Multiple Heads ,Variations , Vertebral Border of Scapula ,Scapular Flaps ,Surgeons ,

Aim to study the variant deltoid muscle. 100 upper limbs of 50 donated embalmed cadavers (45 males & 5 females) of age group ranging from 70 to 80 years were dissected in the department of Anatomy at K. J. Somaiya Medical College, Sion, Mumbai, INDIA. The variant deltoid muscle was observed in 2 specimens. The neurovascular pattern in the arm was also observed. The photographs of the variation of the deltoid muscle were taken for proper documentation. The multiple heads of the deltoid muscle was observed in 2 specimens. The posterior fibers of the left deltoid muscle were enclosed in a distinct fascial sheet and the deltoid muscle was seen to arise from the middle 1/3 of the vertebral border of the scapula. However there was no variation in the blood supply and the nerve supply of the deltoid muscle. The existence of the multiple heads of the deltoid muscle should be kept in mind by surgeons operating on deltoid, posterior deltoid, or doing scapular flaps.
