Progressive Arterial Insufficiency in a Displaced Salter-Harris Type 1 Distal Femoral Fracture: A Case Report.

Case: A 17-year-old male patient presented with Salter-Harris type I hyperextension injury of left distal femur with delayed development of acute limb ischemia secondary to popliteal artery injury.

Conclusion: Popliteal artery injury associated with distal femoral physeal fracture may not be clinically obvious at the time of initial presentation. When initial pulse examination and segmental Doppler measurements are normal, it is important to perform serial examination by experienced examiners because arterial insufficiency may develop over the subsequent 48 hours.
