Classification
The classification of MCP collateral ligament injuries is critical to the guidance of proper management. RCL and UCL injuries utilize the same three stage classification system as follows {1-4}:
- Grade 1: Incomplete tear of the RCL with only few torn fibers – tenderness to palpation and without laxity present on stressing examination
- Grade 2: Incomplete tear of the RCL with a greater number of torn fibers present – increased tenderness to palpation at the radial aspect of the MCP, more prominent swelling and the presence of laxity on stressing but with a definitive end point.
- Grade 3: Complete tear of the RCL – tenderness to palpation, swelling and prominent instability/laxity with no end point on stressing examination
