Collum Chirurgicum'un Morfometrik Değerlendirilmesi

Abstract

fractures constitute approximately 5% of all fractures (2). Fractures of the proximal humerus account over 75% of all humeral fractures (3). In the last 5 years, the incidence of these fractures has increased by 15% (2). Surgical neck is a very frequently fractured area of the proximal humerus as the humerus begins to taper down at this point and is structurally weaker ABSTRACT Purpose: Surgical neck fractures have been a subject to vast numbers of researches, its structural dispositions 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 of humerus and surgical neck. Methods:In order to achieve the above-mentioned objective, measurements were performed on dry humerus specimens from 60 male and 60 female origins. The circumference of surgical neck (SNC) and humerus 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 not between the right-left sides (p=0.054). Although there was a significant difference between male and female HL on the right side (p=0.001), there was no significant difference on the left side (p=0.051). The highest 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 value obtained in females (4.84 cm2). There was a significant difference between sexes for both indexes (p<0.05). Conclusion:The morphometric data of this area may be utilized for forensic investigations, it may provide insight for the fracture treatments and solving clinical problems. We are opined that since the measurements of surgical neck varies in male and female samples, it may be an essentially important structure in determining sex of a given skeleton.
