Sexual Dimorphism in Scaphoid Dimensions Among Undergraduate Students

Abstract

The scaphoid is the largest bone in the proximal row of the carpal bones and occupies an important position within the wrist joint. Its dimensions contribute to the structural arrangement and functional mechanics of the wrist, while variations in its morphology may have clinical and anthropological significance. Differences in scaphoid dimensions between males and females may provide useful information on sexual dimorphism and contribute to the understanding of anatomical variation within young adult populations. The study will assess sexual dimorphism in scaphoid dimensions among undergraduate students. Specifically, it will determine selected dimensions of the scaphoid in male and female participants and compare the measurements between the two groups. The study will also assess the extent to which the measured scaphoid parameters demonstrate observable differences between male and female participants. A cross-sectional descriptive research design will be adopted for the study. Undergraduate students who meet the established inclusion criteria will be selected using an appropriate sampling technique. Selected dimensions of the scaphoid will be obtained using standardized osteological or imaging-based measurement procedures, depending on the study setting. The collected data will be analyzed using descriptive statistics such as mean and standard deviation, while appropriate inferential statistical tests will be used to determine significant differences between male and female measurements. The study is expected to reveal measurable variation in scaphoid dimensions among the participants and may demonstrate differences between male and female groups. The findings are expected to provide information on the dimensional characteristics of the scaphoid and the pattern of sexual dimorphism within the study population. Such information may contribute to a better understanding of variation in carpal bone morphology. The findings will be useful to anatomists, anthropologists, radiologists, orthopaedic professionals, forensic practitioners, and other healthcare professionals involved in the assessment of wrist anatomy. The study may provide useful reference data for comparative anatomical research, radiological interpretation, forensic skeletal assessment, and clinical evaluation of the scaphoid. The study will conclude by describing the observed differences in scaphoid dimensions between male and female undergraduate students. It will recommend the use of standardized measurement procedures in studies of carpal bone morphology and encourage further research involving larger and more diverse populations to establish broader anatomical reference data on scaphoid dimensions.
