Hallux Valgus: Diagnostic Tests

Obligatory medical device diagnostics.

  • Conventional radiograph of the foot in the dorsoplantar radiographic pathway (from the dorsum of the foot to the sole of the foot), possibly also in the oblique radiographic pathway (with weight bearing on the foot) [measurement of the angle between metatarsals I and II/intermetatarsal angle; assessment of congruency (congruency of joint surfaces) at the metatarsophalangeal joint of the big toe/subluxation?; signs of osteoarthritis? (e.g., joint space narrowing, subchondral sclerosis/calcification)]

Severity classification of a hallux valgus

Light Moderate Severe
Intermetatarsal angle 11-15° 16-20° > 20°
Hallus valgus angle 21-30° 31-40° > 40°
