Total Hip Replacement and Distal Femur Shaft Non-union in a Case of Below-knee Amputation - A Case Report.

Introduction: Primary total hip replacement (THR) surgery for the neck of femur (NOF) fracture in a case of below-knee amputation with distal femur shaft non-union is rare.

Case Report: This case describes the traumatic right NOF fracture in a 49-year-old male patient with distal femur shaft non-union. The patient has a history of ipsilateral below the knee amputation along with right distal femur shaft fracture managed with retrograde femur nailing 10 months back following a road traffic accident. The NOF fracture was managed by primary THR as the definitive procedure after distal femur nail removal and distal femur plating with allograft for non-union.

Conclusion: Primary THR with distal femur plating and allogenic bone grafting in such cases provides satisfactory outcomes. It allows for early ambulation and rehabilitation of the patient.
