Summary
Magnetic resonance (MR) imaging accurately detects peroneal tendon tears, including peroneus brevis and peroneus longus. This study confirms MR
Area of Science:
- Radiology
- Orthopedic Imaging
- Musculoskeletal MRI
Background:
- Peroneal tendon tears are a common cause of lateral ankle pain.
- Accurate diagnosis is crucial for effective treatment planning.
Purpose of the Study:
- To evaluate magnetic resonance (MR) imaging findings of surgically confirmed peroneal tendon tears.
- To correlate MR findings with surgical outcomes for peroneal tendons.
Main Methods:
- Retrospective review of 12 patients (14 tendons) with suspected peroneal tendon tears who underwent surgery.
- Analysis of sagittal and oblique axial T1- and T2-weighted MR images.
- Comparison of MR findings with intraoperative surgical results.
Main Results:
- MR imaging correctly identified peroneal tendon tears in 12 of 14 tendons.
- The most common MR finding was increased signal intensity within the tendon substance.
- Tendon distortion was observed in severe cases, correlating with longitudinal tears.
Conclusions:
- Magnetic resonance imaging is effective in detecting both peroneus brevis and peroneus longus tendon tears.
- MR findings, particularly increased signal intensity and tendon distortion, are valuable indicators of peroneal tendon pathology.
