Aim:To find out assocition between regression in tension trabeculae of proximal femur with ageing.Method: Volunteers of age ≥ 21yrs with defined inclusion and exclusion criteria enrolled for the study and radiographed as per mentioned protocols. Results:  276 ∕ 300 were evaluated. we found significant linear trend  of regression from fine mesh in 98.48% to completely reabsorbed in46.3% in extreme of age.In middle of age from Coarse51.02% to Markedly coarsened in 65.3%. Conclusion: We have found strong association of age with regression tension trabeculae of proximal femur and it is highly sensitive for age estimation .
