KEY IMAGES

CASE FINDINGS

• Mild extensor origin tendinosis without macrotear or radial collateral ligament injury.
• High-grade partial tear versus complete tear of the anterior band of the ulnar collateral ligament midsubstance proximal nonretracted greater than 75% of the ligament is torn but not avulsed. Mild adjacent flexor strain without avulsion. Mild soft tissue swelling. Slight peel-away of the distal attachment of the UCL from the sublime tubercle.
• Normal biceps triceps and brachialis attachments.
• Swollen ulnar nerve.
• Normal radial nerve branches median nerve.
• No internal derangement or OCD. No loose body.
• No muscle atrophy or tear.

CASE CONCLUSION

• Anterior band ulnar collateral ligament tear near complete greater than 75% midsubstance proximal nonretracted tear with additional finding of slight stripping of the distal UCL from the sublime tubercle.  No avulsion fracture.  Mild adjacent flexor strain without tear.  Soft tissue swelling.
• No internal derangement. Swollen ulnar nerve
