Surgical exposure of the femur in dogs was studied from the lateral and medial aspects of the thigh.
The preferable approach for surgical exposu¬re of the femur is from the lateral aspect of the thigh along its whole length between the biceps femoris and vastus lateralis.
From the medial aspect of the thigh exposure of the femur at its distal half between the tendon of pectineus muscle and vastus medie¬lis is easier than that at the proximal half between the fleshy part of the pectineus mu¬scle and the adductor muscle.
In cases of simple shaft fracture the later¬al exposure of the femur is indicated but in cases of supracondyloid fracture the distal medial exposure is recommended
