Summary
Magnetic resonance imaging (MRI) can identify tears in the spring ligament, a key structure for adult-acquired flatfoot. A full-thickness gap on MRI is a strong indicator of a surgically confirmed spring ligament tear.
Area of Science:
- Orthopedic imaging
- Foot and ankle anatomy
- Musculoskeletal radiology
Background:
- Spring ligament injuries are increasingly recognized in adult-acquired flatfoot.
- Limited literature exists on the MRI characteristics of spring ligament abnormalities.
- Accurate diagnosis is crucial for effective surgical management.
Purpose of the Study:
- To describe the MRI appearance of surgically confirmed spring ligament tears.
- To correlate imaging findings with surgical outcomes.
- To aid radiologists in diagnosing spring ligament tears.
Main Methods:
- Retrospective review of MRI scans in patients with surgically proven spring ligament tears.
- Analysis of specific MRI findings: caliber, signal intensity, waviness, and presence of a gap.
- Correlation of MRI findings with surgical findings.
Main Results:
- Common MRI findings included abnormal caliber, signal intensity, and waviness of the spring ligament.
- A full-thickness gap in the spring ligament was observed in 79% of cases.
- Posterior tibial tendonopathy was also frequently noted.
Conclusions:
- MRI findings suggestive of spring ligament tears include altered caliber, signal intensity, waviness, and a full-thickness gap.
- A full-thickness gap is a highly specific finding for surgically confirmed tears.
- Combined MRI abnormalities, particularly a full-thickness gap, increase diagnostic confidence for spring ligament tears.
