Morphometric study of sexual dimorphism by estimation of maximum length and width of left human scapula in adult Bangladeshi people

Abstract

Context: The scapula is a complex bone of the shoulder girdle that exhibits sexual dimorphism and shows population-specific variations. Understanding its morphometry is crucial for forensic identification, anthropological studies, and clinical applications, particularly in orthopedic and reconstructive surgeries. Objectives: This study aimed to assess the morphometric study of maximum length and width of left human scapula in Bangladeshi people. Methods: This cross-sectional analytical study was conducted at Dhaka Medical College from July 2022 to June 2023. A total of 140 dry fully ossified left human scapulae were examined, comprising 66 male and 74 female specimens identified through discriminant function analysis. Statistical analysis was performed using SPSS version 25.0, employing unpaired Student's t-test for comparison between sexes. Results: Maximum length of scapula (male: 136.07±11.37 mm, female: 131.51±11.96 mm, p
