Mohanty et al reported equations for estimating the total length of the humerus from its fragments. The height of a person can be then estimated from the length of the humerus. The authors are from the MKCG Medical College in Berhampur, India.
Population: south Indian adults
Bone selection: dried and fully ossified
Measurement: along the imaginary long axis of the humerus, in mm

a to b (H2) |
32 to 35 mm |

where:
• The segment a to f would be the total length of the humerus.
• Segment c to d would comprise most of the diaphysis.
• Standardized measurement is needed for reproducible results.
