Standardizing the technique of measurement of the collo-diaphyseal angle.

Anatomically the female pelvis because of its reproductive function is broader than that of the male. The female, being genetically shorter than the male, has a shorter femur which, combined with the broad pelvis, results in a comparatively smaller collo-diaphyseal angle than the male. When relevant literature was reviewed mixed results were seen which appear to have been settled by this study. By the adoption of anatomical landmarks for measuring the angle as against the conventional methods this study guarantees comparable results.
