BACKGROUND The objective of this study was to compare angular measurements in the evaluation of hallux valgus deformities using a goniometer and a computerized program to assess degree of concordance between the two methods and determine the reliability of manual measurements. METHODS Angles measured included the hallux valgus angle (HVA), the intermetatarsal angle (IMA), the distal metatarsa...

HYPOTHESIS Does metatarsal pronation exist and, if so, what is its impact? INTRODUCTION Hallux valgus is a deformity associating angulation and a rotational component. The present study sought to investigate the nature and origin of the coronal plane displacement. MATERIALS AND METHODS A prospective single-center radiological and anatomic study was conducted on 100 feet operated on for hall...

BACKGROUND The abductor hallucis muscle plays an important role in maintaining alignment of the first metatarsophalangeal joint. The aims of this study were (1) to determine differences in abductor hallucis muscle characteristics in people with hallux valgus between three age groups (20-44 years, 45-64 years, and 65+ years); and (2) to determine the association between age and abductor hallucis...
