between the knee and
ankle joints

6. There are two bones in the leg
Fibula

7. There are two bones in the leg
The Fibula
•Lies Laterally
•Is shorter
•Is not a weight-bearing bone

8. The Fibula and Tibia are
joined together by the
Interosseous Membrane

13. The Proximal Fibula
(Head of the Fibula)

14. The Proximal Fibula
The Head of the Fibula is
quadrilateral in shape

15. The Proximal Fibula
On the upper surface
is a smooth oval facet
covered in articular
hyaline cartilage

16. This region articulates
with the
Lateral Tibial Condyle
The Proximal Fibula
On the upper surface
is a smooth oval facet
covered in articular
hyaline cartilage

17. This articulation is called the
Superior Tibiofibular Joint

18. The Proximal Fibula
The Styloid Process or
Apex of the Head of the Fibula
lies postero-lateral to the
articular facet

19. Arcuate Popliteal Ligament
and
Fibular Collateral Ligament
attach to the Styloid

22. The Neck of the Fibula is
immediately distal to the
Head of the Fibula
The Proximal Fibula

23. The Proximal Fibula
The Common Peroneal Nerve
wraps around the
Neck of the Fibula before dividing
into its two terminal branches
•Superfical Peroneal Nerve
•Deep Peroneal Nerve

24. Borders of the Fibular shaft

25. The Fibula is triangular in cross-section and has
3 borders and 3 surfaces
Each surface is associated with a different group of
muscles

26. The Fibula has 3 borders and 3 surfaces

When a patient lies in the
scanner, the foot usually points
outwards due to the natural
resting position of the body,
and not directly forwards as in
the standing position
This means that when
interpreting scans remember
that the anterior surface
rotates anticlockwise for the
right leg and clockwise for the
left leg
