Morphometric Analysis of the Scapula and Their Differences between Females and Males

Abstract

Sexual dimorphism is a key role for forensic anthropology. It allows ascertaining the sex of certain biological discoveries. By postmortem studies it is possible to establish a profile of individuals. This profile allows the identification in cases where bodies are skeletonized. Several bones present dimorphism and have been studied to increase approach for forensic identification. This study morphometrically evaluated the scapula bone and compared the measurements between scapula bone of female and male cadavers. Sixty parts were utilized in this experiment. All cadavers belonged to the Department of Animal Morphology and Physiology of the Federal Rural University of Pernambuco. The scapula bones were photographed and measured through software ImageJ®. Eight parameters of measurements were considered: scapula height (SH), distance between basis and spine (DBSp), scapula width (SW), spine width (SpW), acromion-coracoid width (ACW) and scapula body width at 2 (L2), 4 (L4) and 6 (L6) cm of the lower angle. The median morphometric values for the male scapulas were: SH -

Morphometric, anatomic and radiographic study of the scapula in the white‐footed tamarin (Saguinus leucopus): report of scapular cartilage and one variation in cranial (superior) transverse scapular ligament

“…; Oliveira‐Costa et al. ), similar to this study in S. leucopus . The differences found in the sizes of the bones in males and females are attributed in humans to the distribution of the work according to sex in ancient humans, when men had to perform greater physical efforts, which required a greater dietary protein requirement, and they therefore developed larger muscles and bones (Charisi et al.…”

“…; Oliveira‐Costa et al. ). Scapular growth depends almost entirely on the development of their associated muscles (Hrdlička, ).…”

Acromion types and morphometric evaluation of painful shoulders

“…The averages obtained from the values of the measures of the scapula were significantly higher in the population of male individuals [5]. A lot of studies given, the means of acromion lengths of males are higher than the ones of females [1,6,18].…”

Clinical Significance of the Morphometric Structures of the Scapula with the Emphasis on the Glenoid Cavity

“…The shoulder provides this range of motion with the simultaneous movement of five joints. These joints are the sternoclavicular, acromioclavicular, glenohumeral, scapulothoracic, and subacromial from medial to lateral (1,(7)(8)(9). In addition, the scapula plays a major role in the strength, and energy of shoulder function.…”
