- Grade 1: First MTP capsule stretched
- Mild symptoms
- Athlete usually able to continue sports participation
- Grade 2: MTP plantar ligamentous complex partial tear
- Swelling and Ecchymosis
- MTP range of motion decreased
- Grade 3: MTP plantar ligamentous complex complete tear
- Significant swelling and Ecchymosis
- Significantly limited MTP range of motion
- Patient has difficulty even walking
V. Imaging: Great Toe XRay (weight bearing)
- Evaluate for conditions on differential diagnosis
VI. Differential Diagnosis
- Hallux Rigidus
- Sesamoid Stress Fracture
- Metatarsal Fracture
- Avulsion Fracture
VII. Complications
VIII. Management
- Low grade sprains heal in weeks
- High grade sprains may require immobilization
