Technical Tuesday Trochlea

Technical Tuesday Trochlea

A trochlea is an anatomical structure that acts like a pulley. It can be bony or fibrous and has a grooved structure that allows tendons or other structures to glide – like the grooved wheel on an actual pulley.

There is a trochlea in the eye, in the leg, in the foot, and in the arm. It gets around (no pun intended).
Here is a short list of some trochleas:

            Trochlea of humerus (part of the elbow hinge joint with the ulna)
Trochlea of femur (forming the knee hinge joint with the patella)
The trochlea tali in the superior surface of the body of talus (part of the ankle hinge joint with the tibia)
In quadrupeds, the trochlea of Radius (bone)

Probably the most interesting trochleas for dancers are in the knee and the foot. If you google “trochlea” you will find lots of photos and descriptions, including various common injuries.
