Clinical Features: A 29-year-old male patient sustained a left ankle injury when the front edge of his wakeboard became immersed in the water. As he fell forward, his foot remained attached to the board, leading to inversion and dorsiflexion stress of the ankle. He presented to a chiropractic clinic with diffuse ankle swelling, tenderness, and pain at the distal aspect of the lateral malleolus. Mild ligamentous laxity of the lateral supporting structures was observed during the physical examination.

Intervention and Outcome: Static and stress radiographs of the left ankle demonstrated a small (McCrory-Bladin type 1) lateral talar process fracture without evidence of gross instability. The patient was referred to a local orthopedic medical specialist for immobilization of the ankle. The patient was treated conservatively with an air cast walking boot for 2 weeks (non–weight-bearing) followed by a 2-week period of partial weight-bearing. At 6 weeks following the injury, a repeated radiographic examination demonstrated complete healing of the fracture. The patient reported minimal tenderness and normal ankle function.

Conclusion: Because of the similar mechanism of injury to those sustained in snowboarding, this case demonstrates the need for increased awareness of lateral process fractures in wakeboarders.
