Abstract
Posterior ankle impingement pain is caused by the compression of the posterior ankle bony and soft tissue structures during terminal flexion. The fibro-osseous tunnel along the talus and calcaneus is the potential entrapment site of the flexor hallucis longus tendon. MRI is the gold standard to evaluate the FHL tendinopathy, soft tissue inflammation, and bony edema at the os trigonum. Symptoms that are recalcitrant to conservative treatment and/or high-level athletes often require open versus arthroscopic surgical intervention. Potential complications following posterior arthroscopy include iatrogenic injury to the tibial nerve, sural nerve, and medial calcaneal nerve injury.
