Abstract
Background: Rigid interlocking nailing for femoral shaft fracture is ideal for use in adolescents in terms of stability of the fracture and convenience for the patient. Closed reduction and intramedullary interlocking nailing is the surgical treatment of choice for the closed shaft fractures of femur. Present study conducted to study the principles of intramedullary interlocking nailing and to assess the outcome of the patient.
 Methods: The present study comprises of 30 cases of fracture shaft of the femur in adults about >20 years old. All the fractures, which were included in the study were traumatic in origin, most of them are due to road traffic accidents.
 Results: The delayed union rate in our series was 6.67%. There were no non-unions.
 Conclusions: It is concluded that closed intramedullary interlocking nailing method given good result in treatment of shaft fractures of femur.

Highlights
At the beginning of intramedullary nail era, the conventional intramedullary nails by closed methods, gained wide popularity in transverse fracture of the middle 1/3rd of the femur due to no disturbances of periosteal blood supply, fracture hematoma, and rapid healing of fracture with lesser risks of complications like infection, non-union and shortening
The study consists of 30 cases of fracture shaft of the femur treated by closed intramedullary nailing with interlocking intramedullary nail
Of the 26 fractures treated by closed intramedullary nailing, majority were closed fractures, while the remaining were open fractures
Summary
At the beginning of intramedullary nail era, the conventional intramedullary nails by closed methods, gained wide popularity in transverse fracture of the middle 1/3rd of the femur due to no disturbances of periosteal blood supply, fracture hematoma, and rapid healing of fracture with lesser risks of complications like infection, non-union and shortening. Still it had its draw backs in references to comminuted fractures of the femurs as in not providing rotational stability and axial length. This method provided immediate leg length and rotational stability to the fracture and allowed the patient to be mobilized without risks of shortening.
