Morphological And Morphometric Study Of Dry Scaphoid Bone In The North Indian Population

ABSTRACT

Background: A review of the relevant literature showed that previous descriptions of scaphoid were not detailedenough to match our present clinical knowledge or the requirements of modern imaging especially in the NorthIndian population. With this in mind a study was conducted on 50 dry cadaveric scaphoids of North Indianorigin.Material and Methods: The study was performed on 50 dry human scaphoid bones of the North Indian population.Various morphological and morphometric parameters were observed and measured using vernier callipers, anon-stretchable thread, centimetre scales and a protractor.Results: All the morphological parameters studied were present in all the 50 bones except the sulcus for flexorcarpi radialis that was absent in 12 and the ridge for the scapho-capitate interosseous ligament that was absentin 13 bones. The tubercle was conical in 36, pyramidal in 13 and round in the remaining 1 bone. The maximallength of scaphoid and the thickness of waist were significantly higher on the right side. 30 bones had equallydeveloped, 10 bones had under developed proximal while the remaining 10 bones had under developed distalpole. The average value of anteroposterior intra scaphoid angle of 50 scaphoid was found to be 39.20+6.420.Clinical significance: The data obtained in the present study will be helpful for the hand surgeons, radiologists,morphologists and clinical anatomists
