AbstractIntroduction: Diaphyseal femur fractures are mostly the result of high-energy trauma, for which reason they endanger life itself, account for important handicaps, and are usually associated with multilevel injuries. Their most frequent sequelae are limb shortening, poor alignment and stiffness in the knee. Aims and Objectives: To Study of Associated Injuries with Fracture Shaft of Femur and Tibia. Methodology: This study includes retrospective and prospective cases with complex fractures of shaft of femur and tibia admitted at our hospital during the period July 1998 to June 2002. A series of 52 cases of comminuted fractures of shaft of femur and tibia were studied. The study included 21 fractures of shaft femur of which 3 were Grade I compound and 18 were closed and 31 fracture of tibia of which 5 were grade I compound and 26 were closed. Result: minimum age of patient was 12 years and maximum age of patient was 70 years. The mean age was 35.04 years. The peak incidence was observed in age group 21-30 years (36%) followed by 31-40 years (26%). There were 44 (88%) males and 6 (12%) females Out of 31 biologically plated tibia 14 (49.40%) Had no associated injury, 17 (51.50%) had associated injuries which included 6 poly trauma cases Out of 21 biologically plated femur 3 (19.05%) had no associated injury, 18 (80.95%) had associated injury which included 4 poly trauma. Conclusion: Poly trauma was most common cause of Associated injury.
