Background: Rigid interlocking intramedullary nailing for femoral shaft fracture is ideal for use in adolescents and elderly 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 with high union rate and low rate of infection and implant failure. 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 admitted in orthopaedics wards of SSG Hospital & Medical College Vadodara. Total 30 cases considered for closed intramedullary interlocking nailing. Patients were followed up postoperatively for 6 months for clinical and radiological evaluation and functional outcome.

Results: In 43.33% cases closed intramedullary nailing given excellent healing of fracture, in 48.7% cases healing was good, and 7.7% cases poor healing was observed due to associated injuries.

Conclusions: The advantages of this procedure include that no fracture site is opened, there is a shorter operation time, less radiation exposure, It is concluded that closed intramedullary interlocking nailing method given good result in treatment of shaft fractures of femur, especially suitable for multiple trauma and obese patients.
