48-years old patient with symptomatic intraosseous calcaneal ganglion.

Picture 1: CT scan shows an intraosseous cyst in the calcaneuswith an opening in the posterior talocalcaneal joint near the sinus tarsi.

Picture 2: Picture showing the entrance of the cyst before (left) and after (right) debridement and microfracturing. Access by means of a 2-portal sinus tarsi approach. A forced inversion of the foot brings the calcaneus forward. Thus dislocating the opening of the cyst in the posterior talocalcaneal joint.
