I understand your concern. I have a patient at this time who has the same problem. The os trigonum is the posterior process of the talus. The long flexor tendon to the big toe runs through it. If it is attached to the talus it is called a Stieda's process. If it exists as a seperate bone it is an os trigonum. It can bridge to the main body of the talus either through a fibrous or cartilage attachment.
The best way to see how to proceed to to rest it first. A CT scan might be also helpful. This is not an easy thing to diagnose
