Specific findings during the surgeries included three cases of a duplicate os trigonum
and three cases of a tendon ganglion of the FHL.
An os trigonum
is a small bony ossicle located posterior to the talus.

The posterior-ankle impingement due to os trigonum
can develop after disruption of the os trigonum
through a significant acute injury (for example, fracture, fragmentation, and/or pseudoarthrosis).
The diagnosis of PAIS or FHL tendinopathy was made on the basis of the history and physical examination, with reproduction of the typical pain in forceful plantar flexion or on palpation of the os trigonum
(if present) or the FHL tendon.
An os trigonum
is usually round or oval with well-defined corticated margins, whereas a fracture of the lateral tubercle typically has irregular serrated margins between the fragment and the posterior talus.

The present study reports the clinical results of excision of a symptomatic os trigonum
using an endoscopic procedure in professional ballet dancers.
It started out as tendonitis but after a medical exam I was diagnosed with Os Trigonum
The differential diagnosis of posterior ankle pain is peroneal tendon subluxation, posterior impingement syndrome with painful os trigonum
or trigonal process, posterior talus osteochondritis dissecans, flexor hallucis longus tendinopathy, and posterior tibial tendinopathy.
Secondary problems Lastly, there are several conditions, such as FHL tendonitis ("dancer's tendonitis") and the os trigonum
syndrome that seem to pop up out of nowhere.
