Retrotrochlear eminence

Last revised by Daniel J Bell on 6 Aug 2018

The retrotrochlear eminence is located posterior to the peroneal tubercle and the peroneal tendons.

It is one of two bony projections or protuberances that may be seen arising from the lateral wall of the calcaneum, the other being the peroneal tubercle.

It is seen to be prominent in individuals with a hypertrophied peroneus quartus muscle, the most frequently reported accessory peroneal muscle. The muscle arises from the inferolateral aspect of the fibula and has variable insertions, one of them being the retrotrochlear eminence.
