Background: Osteoporotic fractures are common and occur in aging and elderly population. Of these proximal femur fractures are the most disabling and can result in increased morbidity and mortality. Osteoporosis, determines the type of fracture but also affect reduction of fracture during surgery and post-operative mobility of the individual. Aim: To evaluate the correlation between Osteoporosis, and post-operative mobility in patients, with proximal femur fractures. Null Hypothesis: There is no significant correlation between the Osteoporosis, and post-operative mobility of the patients in a proximal femur fracture. Method: A retrospective study was carried out during the period March 2017 to March 2018 in BIRRD (T) Hospital. Patients, who underwent proximal femur fracture surgeries after fulfilling the inclusion and exclusion criteria, were included in the study. Patients evaluated for Osteoporosis with Singh’s Index, fracture type, Pre and Post-Operative mobility patterns. Results: The study included 50 patients, but complete data was available for 40 patients. Remaining ten patients could not present for follow-up and were excluded from the study. Four patients included in the study, expired during the study. Conclusion: Null hypothesis remains rejected.
