This 1986 case series from Rice University presents 63 metatarsophalangeal joint injuries in 53 collegiate athletes over 14 years. It establishes the foundational three-grade classification for turf toe and defines the role of footwear and playing surface in injury causation. Treatment principles and contraindications — including avoidance of corticosteroid injection — are detailed.
Every time you see a football player limping off a synthetic turf field with a swollen, tender first MP joint, you are looking at a turf toe injury — and the Clanton grading system tells you exactly what to do next.
Grade 1 and 2 injuries return to play with taping, NSAIDs, and a forefoot-stiffened shoe or orthotic. Grade 3 injuries involve articular cartilage damage and require 3 to 6 weeks out. Rushing these players back risks the progressive hallux rigidus seen at long-term follow-up.
Do not inject these joints. Corticosteroids masked pathology and worsened outcomes in this series; the authors explicitly contraindicate them, and that teaching persists in modern practice.
Screen athletes with prior injury or limited dorsiflexion: anyone with less than 60° of first MP motion should be in a stiffened shoe or spring-plate orthotic before the season starts, not after the first injury.
