Penetrating trauma of the femur poses significant life-threatening risks due to potential complications, particularly involving the femoral structures such as the femoral artery, femoral vein, and femoral nerve. These injuries can lead to severe outcomes, especially when accompanied by soft tissue damage. Effective management requires a thorough understanding of the injury's nature, including the extent of soft tissue involvement and associated complications. This report presents a case of a 42-year-old male patient with a penetrating femoral injury through the anterior and posterior aspect of the lower limb without associated fracture, which highlights the importance of prompt surgical intervention and the use of flap reconstruction to address complications such as necrotic soft tissue.
