Update on Adult Acquired Flat Foot Deformity Using MR Imaging

Area of Science:

• Orthopedics
• Radiology
• Medical Imaging

Background:

• Adult acquired flatfoot deformity (AAFD) is a progressive condition affecting the medial longitudinal arch.
• It commonly impacts middle-aged women and is linked to obesity, diabetes, and hypertension.
• AAFD leads to pain and functional impairment.

Purpose of the Study:

• To review the role of MR imaging in evaluating AAFD.
• To detail normal anatomy, pathophysiology, and classification systems for AAFD.
• To outline advanced MR imaging protocols and findings.

Main Methods:

• Literature review focusing on MR imaging in AAFD.
• Analysis of normal foot and ankle anatomy on MR scans.
• Examination of MR findings related to AAFD pathology.

Main Results:

• MR imaging is the gold standard for assessing osseous, tendinous, and ligamentous structures in AAFD.
• Key findings include posterior tibial tendon dysfunction, spring ligament complex tears, and deltoid ligament abnormalities.
• Secondary osseous changes are also important diagnostic indicators.

Conclusions:

• MR imaging is essential for accurate diagnosis and staging of AAFD.
• Understanding specific MR findings aids in effective patient management.
• Advanced imaging protocols improve diagnostic capabilities for AAFD.
