Occipital spurs are quite common; however, they are also the source of frequent discomfort to the patients. Their role has been implicated in causation of pain at the base of skull, which may extend to shoulder limiting the movement of the shoulder and neck. The present was carried out to find out the prevalence of occipital spur in human skull and to find out the anatomic morphological characteristics of occipital spur. A total of 30 cadaveric skulls were examined in the Department of Anatomy, Uttar Pradesh University of Medical Sciences, for the presence of occipital spur. These skulls were the part of boneset obtained as a part of undergraduate training in the department. All the measurements were taken using a digital Vernier Caliper after taking all necessary precaution to avoid any damage to these spurs. The prevalence of occipital spur in the present study was 10%. The mean width recorded in the present study was 13.40 mm (±6.7) and the mean length recorded was 13.45 mm (±1.05). Similarly, mean thickness noted was 2.43 mm (±0.43). Thus, the present study concludes that occipital spurs are the frequent source of discomfort to patients. The knowledge of this tubercle is of paramount importance to neurosurgeons, sports physicians, and radiologists for the diagnosis of such discomfort.
