ABSTRACT: OBJECTIVES: Fractures of the scaphoid are the most common of the carpal bone injuries, because of its connection with the two rows of carpal bones. The scaphoid fractures are slow to heal because of the limited circulation to the bone. Hence they must be recognized and treated quickly, as prompt treatment by immobilization or surgical fixation avoids mal-union or non-union. This study presents the anatomical variations in dimensions and appearance of scaphoid bone. MATERIALS AND METHODS: Thirty dried human scaphoid bones were studied from the Department of Anatomy, Mahathma Gandhi medical college, Puducherry, to identify the possible anatomical variations. The morphometric Parameters were measured with vernier calipers. The circumferences and length were measured using a thread. The number of foramina was observed using a magnifying lens. RESULTS: Out of 30 scaphoid studied, the tubercle was present in all of the bones. Among the left sided scaphoid 7 were conical and 8 were pyramidal in shape. Similarly on the right side 9 were conical and 6 were pyramidal in shape. Most of the scaphoid had main dorsal sulcus (19 Scaphoids) and 11 scaphoids had two dorsal sulci. All the scaphoids had more than five foramina on the dorsal sulcus.
