Abstract
515 patients are observed about their qualitative and quantitative attitude in callus formation.
Several differences are found according to its localization the grade of dislocation and operative injuries.
1. Callus formation are richer in the dislocated than not dislocated.
2. Generally they are in the bridge form and are richer in the concave side.
3. They are good produced in the side of comparatively richer soft supporting tissue and poor in the operative injured.
As a conclusion, callus formation are much influenced not only by the mechanodynamic factor but also the local anatomical factor.
