MORPHOMETRIC CHARACTERIZATION OF THE COLLUM CHIRURGICUM (SURGICAL NECK)

Abstract

Purpose: Surgical neck fractures have been a subject to vast numbers of researches, its structuraldispositions depending on the variants of sex and directional morphometry requires further investigation.Therefore, we aimed to evaluate sex and side differences by using morphometric measurements ofhumerus and surgical neck.Methods: In order to achieve the above-mentioned objective, measurements were performed on dryhumerus specimens from 60 male and 60 female origins. The circumference of surgical neck (SNC) andhumerus length (HL) were measured in centimeter. After the completion of these measurements the area(SNA) of surgical neck was calculated and the data obtained was utilized to create two separate indexes.Results: The circumference of surgical neck differed significantly between the sexes (p=0.001), but notbetween the right-left sides (p=0.054). Although there was a significant difference between male andfemale HL on the right side (p=0.001), there was no significant difference on the left side (p=0.051). Thehighest mean value of the SNC in females (7.13 cm) was lower than the minimum value obtained in males(7.20 cm). The lowest mean value of the SNA in males (4.92 cm2) was higher than the maximum valueobtained in females (4.84 cm2). There was a significant difference between sexes for both indexes(p
