A case of acute tarsal tunnel syndrome following lateralizing calcaneal osteotomy

• Tarsal tunnel syndrome is a rare complication of lateralizing calcaneal osteotomies in patients with CMT and cavovarus feet.
• We report the first case of iatrogenic tarsal tunnel syndrome in a patient without any pre-existing neurological disorder.
• Awareness of this complication and expedient surgical release can lead to a successful outcome.

Surgical correction of hindfoot varus is frequently performed with a lateral displacement calcaneal osteotomy. It has rarely been associated with iatrogenic tarsal tunnel syndrome in patients with pre-existing neurological disease. We report the first case of acute postoperative tarsal tunnel syndrome in a neurologically intact patient with post-traumatic hindfoot varus. Early diagnosis and emergent operative release afforded an excellent clinical outcome. Imaging studies can help outrule a compressive hematoma and assess for possible nerve transection; however it is paramount that a high index of suspicion is utilized with judicious operative intervention to minimize long-term sequelae.
