Patients typically present with pain over the medial bony prominence (bunion), worsened by footwear pressure, and sometimes associated with bursitis. Radiographic Metrics (Weight-bearing): Hallux Valgus Angle (HVA): Normal 40∘is greater than 40 raised to the composed with power Intermetatarsal Angle (IMA): Normal <9∘is less than 9 raised to the composed with power (between 1st and 2nd metatarsal shafts).
Hallux valgus, often referred to as a bunion, is a prevalent forefoot deformity, affecting 23% to 35% of the population, with a higher incidence in women.
