Had x-rayed on Sat~

Thank god no fracture, but "a prominent posterior process of the talus is noted, which is most like a variant of normal".

Talus?

From wikipedia, it's:
"The talus is the second largest of the tarsal bones.
It articulates with the tibia, fibula, calcaneus, and navicular. This means that the talus is one of the bones in the human body with the highest percentage of its surface area covered by articular cartilage. It is also unique in that it has a retrograde blood supply. This simply means that arterial blood enters the bone at the distal end.
It occupies the middle and upper part of the tarsus, supporting the tibia above, resting upon the calcaneus below, articulating on either side with the lateral and medial malleoli, and in front with the navicular."

..... still very chim! wahaha. Anyway, there's the diagram in wikipedia, http://en.wikipedia.org/wiki/Talus_bone


Oh ya, this one is important: Thanks friends for your concern! 我很感动，呵呵。 :)
