The medial collateral ligament is one of the most commonly injured ligaments of the knee. Most injuries result from a valgus force on the knee. The increased participation in football, ice hockey, and skiing has all contributed to the increased frequency of MCL injuries.
How do you check for thumb ligaments?
1. Apply valgus force to the 1st MCP to test the PROPER UCL with the thumb MCP in flexion. This position keeps the proper UCL taut and the accessory UCL loose. The blue line denotes the proper UCL which inserts along the dorsal/ulnar aspect of the 1st metacarpal head.

Can ultrasound distinguish between simple avulsions of the ulnar collateral ligament?
Bony avulsion of UCL. Ultrasound has been successfully used in differentiating Stener lesions from simple avulsions of the ulnar collateral ligament [8, 22, 28], but it may be misleading [36]. Magnetic resonance imaging (MRI) is more accurate (Figs. 3, ,4;4; proximal and distal avulsion) [14, 31].
