Case summary:
31 year old male, synovitis of subtalar origin
Question(s) to this case:
how would you treat?
excision open?
excision combined posterior arthroscopy plus sinus tarsi open?
subtalar fusion primary?
Expert:
What does the radiologist say:
ganglion or chronic synovitis. In case of synovitis it probably is villunodular synovitis.
Theatment in both cases is to resect. I would go by endoscopic aproach starting with 2 portal hindfoor aproach and then a lateral 2-portal sinus tarsi aproach for the anterior part. If you are unconfotable with the sinustarsi aproach then you can perform this part open. Please give us some feedback on the outcome(pathlogy outcome etc)
