UCL Tear â AI-Powered MRI Analysis
Upload your elbow MRI to evaluate ulnar collateral ligament integrity. AI assesses tear location, grade, and associated findings relevant to throwing athletes.
Overview
The ulnar collateral ligament (UCL) of the elbow is critical for stability during overhead throwing. UCL injuries are common in baseball pitchers and other throwing athletes. The anterior bundle is the primary stabilizer and most commonly injured component. Our AI consortium evaluates UCL morphology on coronal and axial MRI, with MR arthrography providing superior sensitivity.
Common Symptoms
- Medial elbow pain during throwing
- Decreased throwing velocity or control
- Popping sensation at the time of injury
- Tingling or numbness in the ring and small fingers
- Instability with valgus stress
Key Imaging Findings
- UCL thickening or signal abnormality on coronal T2
- Partial or complete ligament discontinuity
- T-sign on MR arthrography (contrast leaking under ligament)
- Sublime tubercle avulsion fracture
- Medial epicondyle bone marrow edema
- Ulnar nerve subluxation or neuritis
Frequently Asked Questions
What is Tommy John surgery?
Tommy John surgery (UCL reconstruction) involves replacing the torn UCL with a tendon graft, typically from the forearm or hamstring. MRI is essential for surgical planning, determining tear location and extent, and identifying associated injuries. Return to competitive throwing typically takes 12-18 months.
Can a partial UCL tear heal without surgery?
Some partial UCL tears, especially low-grade tears in non-overhead athletes, may heal with rest and rehabilitation. MRI helps determine the tear grade and location to guide treatment decisions. Complete tears in throwing athletes usually require reconstruction.
