Objective:
The aims of this study were to assess, grade, and surgically correlate previously unreported MRI features of superior peroneal retinacular injuries in nine surgically proven cases and to record all soft-tissue and bony abnormalities associated with these injuries.
Conclusion:
MRI was found to be a useful tool for detecting and grading superior peroneal retinacular injuries and providing information, important for presurgical planning, regarding common concomitant soft-tissue and osseous abnormalities of the lateral collateral ligaments, peroneal tendons, and fibular groove. Superior peroneal retinacular injuries are frequently associated with MRI evidence of peroneal tendon dislocations and tears. Conversely, routine MRI studies may not depict dislocated peroneal tendon injuries, despite clinical history to that effect.
Insights
Magnetic resonance imaging (MRI) effectively detects and grades superior peroneal retinacular injuries. MRI also identifies associated soft-tissue and bone abnormalities crucial for surgical planning.
Area of Science:
- Orthopedic Surgery
- Radiology
- Sports Medicine
Background:
- Superior peroneal retinacular injuries are often challenging to diagnose.
- Accurate assessment is vital for effective surgical intervention.
Purpose of the Study:
- To identify and grade novel MRI features of superior peroneal retinacular injuries.
- To correlate MRI findings with surgical outcomes.
- To document associated soft-tissue and bony abnormalities.
Main Methods:
- Retrospective review of nine surgically confirmed cases.
- Detailed analysis of MRI scans for specific injury patterns.
- Correlation of imaging findings with intraoperative observations.
Main Results:
- MRI demonstrated utility in detecting and grading retinacular injuries.
- Commonly observed abnormalities included peroneal tendon dislocations and tears.
- Associated osseous abnormalities of the fibular groove were noted.
Conclusions:
- MRI is a valuable tool for diagnosing superior peroneal retinacular injuries.
- It aids in presurgical planning by identifying concomitant soft-tissue and bony abnormalities.
- MRI findings should be considered alongside clinical presentation, especially for peroneal tendon injuries.

Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
