This case report describes a rare avulsion fracture of the calcaneus involving the plantar fascia insertion in an adolescent patient following a sports-related injury. The patient presented with acute heel pain, and imaging confirmed a significant avulsion at the plantar fascia’s calcaneal attachment. Unlike the more common Achilles tendon-related avulsion injuries, this case illustrates a less frequently recognized injury pattern in the pediatric population. Management was conservative, consisting of rest, immobilization, and a structured rehabilitation program. The patient achieved full recovery, returning to normal activities without residual symptoms. This case underscores the importance of considering plantar fascia avulsion fractures in adolescent patients with heel pain, particularly in the context of athletic trauma.
