Introduction: Scaphoid is the second largest among all the carpal bones of the hand. It is located on the radial side of the proximal row of carpal bones. Among the carpal bones, scaphoid is more predisposed for fracture. The blood supply of scaphoid is unique, the route taken being from distal to proximal. A waist of scaphoid fracture leads to disruption of blood supply, and eventually leading to avascular necrosis, which warrants a bone replacement surgery. This study is aimed at analysing the morphologic and morphometric parameters of adult human scaphoids among the South Indian population which will act as a useful guide in treatment and procedure for pathologies of scaphoid.
Materials and methods: A total of 100 scaphoids were dissected from 25 male and 25 female cadavers, from Department of Anatomy, Saveetha Medical College. 5% potassium hydroxide solution was used to loosen the soft tissues and vernier and thread were used to measure the scaphoids.
Results: All the 100 scaphoids showed the presence of tubercle. 77% showed the presence of one main dorsal sulcus. Double foramina in the main dorsal sulcus was seen in 42 right and 48 left specimens. Differences were also found in length, waist and proximal, middle and distal width of the bones.
Conclusion: The data obtained from the present study was compared with previous studies and significant morphologic and morphometric differences were found between right and left side and among other studies. This study might prove useful in the intervention of fracture scaphoid for radiologists and orthopedicians.
