Hallux Varus: An Underreported Presentation of Rheumatoid Arthritis.

UNLABELLED: The prevalence of hallux varus deformity in rheumatoid arthritis (RA) has been reported to be extremely rare. However, in South Asian Countries, where open-toed shoes are habitual footwear for the majority of people, we have found that hallux varus is a common deformity in patients with RA. This rate of occurrence is much more common than that in published hallux deformities in RA and reinforces the impact of footwear on the development of hallux deformities. In this report, we present 3 illustrative cases of hallux varus developed in patients with RA and review the etiology of hallux varus deformity.

LEVELS OF EVIDENCE: Therapeutic, Level IV: Case Study.
