The size of the radiographic first intermetatarsal (IM) angle is one of the main considerations in selecting a surgical procedure for hallux abducto valgus. Instead of directly measuring the IM angle with a goniometer or a virtual measurement system, physicians will often estimate the size of the IM angle by direct visual estimation
