X-ray showing measurements of HV and IM angles of hallux valgus.<unk>  can be diagnosed and analyzed with a simple x-ray, which should be taken with the weight on the foot. The hallux valgus angle (HVA) is the angle between the long axes of the proximal phalanx and the first metatarsal bone of the big toe. It is considered abnormal if greater than 15–18°. The following HV angles can also be used to grade the severity of hallux valgus: * Mild: 15–20° * Moderate: 21–39° * Severe: ≥ 40° The intermetatarsal angle (IMA) is the angle between the longitudinal axes of the first and second metatarsal bones, and is normally less than 9°. The IM angle can also grade the severity of hallux valgus as: * Mild: 9–11° * Moderate: 12–17° * Severe: ≥ 18°
