Hallux valgus deformity is characterized by lateral deviation of the proximal phalanx on the metatarsal head. Variable severity of the deviation causes prominence of the medial eminence, giving rise to a painful bunion deformity. Many patients will find permanent or temporary relief with non surgical measures. For those who failed conservative treatment, surgery may cure their symptoms. However unsatisfactory outcomes following hallux valgus surgery is not rare. Therefore a clear understanding of the pathology and of the patient's expectations must anticipate any treatment strategy in order to optimise patient's outcome. Cosmetic considerations should never be an indication for surgery.
