Background: Full anatomical stature estimation in forensic and anthropological experts is often limited by unavailability of complete bones after natural or man-made disasters.
Objective: This study investigates on morphometry of humerus and estimation of its length from bony segments using univariate and multivariate regression equations in Indian population.
Methodology: Total of 401 dry humerus (200 left, 201 right) were taken and analyzedafter excluding deformed, incompletely ossified bones.Measurements of replicable humeral bony segments was taken along its longitudinal axis. In addition, dimensions of bicipital groove and supratrochlear foramen (STF) were also recorded. For estimating humeral length, univariate and multivariate regression equations were generated for individual segments and in combination of significant segments respectively.
Results: Mean longitudinal length (left side:30.27±1.691 right side:30.46±1.899), bicipital groove dimensions and presence of STF between right versus left side didn’t differ significantly (P>0.05). Presence of STF was higher(36 out of 401 bones), showcased the necessity of expecting its presence during orthopedic, radiological examinationsamong Indian population.Only few segments were found significantly impacting the humeral length (P>0.05). The multiple regression models were reliable forestimating humeral length (P<0.05), which was evident from close agreement between predicted versus actual values.
Conclusion: The regression model developed in the current investigation may could be useful in estimation of stature of skeletal remains in anthropometric, forensic, archaeological investigations. It could also serve in comparative studies on Indian population regarding other humeral parameters.
