Arthroscopic Treatment for Stieda’s Process Fracture Excision with Posterior Ankle Impingement Syndrome Release

Abstract Posterior ankle impingement can stem from various sources, encompassing both bony and soft-tissue causes, with origins in either traumatic or nontraumatic events. In this instance, we present an uncommon case involving hindfoot pain resulting from impingement caused by Stieda’s process fracture. The patient, a 28-year-old female, underwent hindfoot arthroscopy, during which the Stieda’s process fracture fragment was excised along with the decompression of the Flexor hallucis tendon. Subsequently, she was immobilized in a plaster of Paris slab for 1 week, followed by a period of 3 weeks of mobility with a Cam boot walker. Over the course of her follow-up appointments, her pain lessened, and her range of motion improved, allowing her to return to her normal activities.
