Summary
Severe injuries to the plantar ligamentous complex or medial collateral ligament, along with participation in high-level sports, predict the need for surgery in first MTP joint injuries.
Area of Science:
- Orthopedics
- Radiology
- Sports Medicine
Background:
- First MTP joint injuries are common in athletes.
- Predicting surgical management is crucial for patient outcomes.
Purpose of the Study:
- To identify MR imaging findings and demographic factors that predict surgical intervention for traumatic first MTP joint injuries.
Main Methods:
- Retrospective review of 161 forefoot MRIs for first MTP joint injuries.
- Radiologists assessed ligamentous, osseous, and tendinous injuries.
- Clinical data and imaging findings were analyzed using logistic regression.
Main Results:
- Grade 2 or 3 injuries of the plantar ligamentous complex and medial collateral ligament predicted surgery.
- Participation in collegiate or professional sports was also a significant predictor.
- Other imaging findings and demographic factors did not predict surgical management.
Conclusions:
- Tears in the plantar ligamentous complex or medial collateral ligament, and high-level sports participation, are key predictors of surgical management for first MTP joint trauma.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
