Height prediction by measuring ulnar length in females

Context: Stature estimation is frequently required by the Forensic Science experts which more often done on the skeletal remains. Since 1950`s the long bones in the human body for eg Humerus, ulna, Femur and Tibia are used for stature identification .Arm Span, nose length have also been used for height prediction. A study was needed to find out such a correlation in females as few studies have been conducted . Objective: To formulate an equation and relation for estimation of stature in living adult females by the measurement of their ulna bone. Method: This study was conducted in Sri Ramchandra Medical College Chennai and Dubai medical college for girls. Female participants who were chosen from faculty and students. Crown to heel measurement and ulnar length measurements (From tip of olecranon process to tip of styloid process) were done. Result: In the present study, the average height in 100 females was seen to be 162cm, the average length of right ulna was 25.7 and average length of left ulna was 25.4cm. The correlation coefficient(r) of the height and the length of the left ulna was (0.85) and that for the right ulna (0.81). Left side with height (0.85) The value of r implied that there was a positive correlation Conclusion: Being a percutaneous bone Ulna can be easily palpated and measurements for length can be taken reliably. A relation between height and length can be studied easily which will be beneficial for Anatomist, Clinicians and anthropometry studies.
