Summary
Metatarsophalangeal joint instability is often linked to plantar plate tears and other foot pathologies. This review examines diverse conditions affecting this critical foot joint.
Area of Science:
- Orthopedic Surgery
- Podiatric Medicine
- Radiology
Background:
- The metatarsophalangeal joint is crucial for foot function.
- Plantar plate injuries are a common cause of forefoot pain and instability.
- Understanding associated pathologies is key for effective treatment.
Purpose of the Study:
- To review imaging findings of metatarsophalangeal joint instability.
- To illustrate the spectrum of pathologies associated with plantar plate tears.
- To share institutional experience in diagnosing and characterizing these conditions.
Main Methods:
- Retrospective review of imaging studies from May 2002 to May 2006.
- Correlation of imaging findings with clinical diagnoses.
- Pictorial presentation of representative cases.
Main Results:
- Plantar plate tears were frequently observed in patients with metatarsophalangeal joint instability.
- A variety of concurrent pathologies were identified, including synovitis, arthritis, and tendon abnormalities.
- Imaging characteristics varied depending on the specific pathology.
Conclusions:
- Metatarsophalangeal joint instability encompasses a range of pathologies beyond isolated plantar plate tears.
- Comprehensive imaging review is essential for accurate diagnosis.
- This pictorial review highlights key imaging features for improved understanding.
