Distal Femur Fracture Above a High Below-The-Knee Amputation Managed With Lateral Locking Plate

Case: We report the case of a patient with a below-the-knee amputation who sustained a complex femur fracture ipsilateral to his residual limb after a fall from height. His fracture was managed with a lateral locking plate of the distal femur for fixation. He was followed for 16 months; at 7 months, he demonstrated return to pretrauma functional status. Conclusion: Fixation of the distal femur with a lateral locking plate did not interfere with the patient's ability to wear a prosthesis and should be considered for managing “periprosthetic” femur fractures in those with a below-the-knee amputation to maintain prosthetic usage.
