Summary
Magnetic resonance (MR) imaging effectively detects posterior tibial tendon dysfunction, including tears and tenosynovitis. Familiarity with MR findings aids in accurate diagnosis of this common foot condition.
Area of Science:
- Radiology
- Orthopedics
- Musculoskeletal Imaging
Background:
- Posterior tibial tendon dysfunction is a common cause of medial foot pain.
- Accurate diagnosis is crucial for effective treatment planning.
Purpose of the Study:
- To describe the magnetic resonance (MR) imaging findings in patients with posterior tibial tendon dysfunction.
- To evaluate the effectiveness of MR imaging in characterizing abnormalities of the posterior tibial tendon.
Main Methods:
- Retrospective review of MR images and medical records for 17 patients (11 with surgical confirmation, 6 with clinical evidence).
- MR examinations utilized T1-weighted and T2-weighted spin-echo sequences in oblique axial and sagittal planes.
- Correlation of MR findings with surgical outcomes where available.
Main Results:
- All 17 patients exhibited abnormal MR findings.
- MR findings included isolated paratenonitis (n=3), tendinosis (n=1), partial tears (n=11), and complete ruptures (n=2).
- MR imaging demonstrated good correlation with surgical findings, though some discrepancies were noted, particularly in differentiating severe tendinosis from partial tears.
Conclusions:
- MR imaging is a valuable tool for detecting and characterizing abnormalities associated with posterior tibial tendon dysfunction.
- Understanding the spectrum of MR appearances is essential for accurate diagnosis and patient management.
