Femoral Triangle

Within the triangle in a medial-to-lateral position is the neurovascular bundle represented by the femoral sheath, which has three components the lateral one contains the femoral artery, the intermediate one the femoral vein, and the medial, and smallest, compartment is called the femoral canal. The neurovascular bundle encases efferent lymphatic vessels and a lymph node embedded in a...

Fig. 39.5 Arthroscopic and navigation views of the lateral femoral condyle and the femoral guide in the left knee, (a) Arthroscopic view of the lateral wall of the femoral intercondylar notch can be obtained through the anteromedial portal with the knee at 90° flexion. The black triangles show the previous incompletely malpositioned tunnel aperture. The tip of the femoral guide is placed within the anatomical femoral footprint through a far anteromedial portal, (b) Navigation view of the lateral wall and roof of the femoral intercondylar notch on the three-dimensional reconstructed image. The white arrow shows the previous incompletely malpositioned tunnel, and the blue line shows the tip of the femoral guide...

Normally a line extended along the superofemo-ral neck proximally should intersect the lateral portion of the femoral epiphysis (Klein s line) (Klein et al. 1951). In addition, a dense triangle formed by the overlapping of the inferior aspect of the metaphysis and the acetabulum is usually visible. Both these normal features are lost wdien the epiphysis has slipped (Bloomberg et al. 1978). 

Fig. 13.5. a AP radiograph of the pelvis of a 14-year-old boy with left slipped capital femoral epiphysis, b The features of the normal right hip are emphasised on the same radiograph. A line drawn along the femoral neck intersects the epiphysis (Klein s line), and a dense triangle of bone is seen where the metaphysis of the hip overlies the acetabulum. These features are not seen on the abnormal left side, c The frog leg lateral radiograph of the same patient clearly shows the left slipped epiphysis...
