A 55-year-old woman with a complicated infected nonunion after first metatarsophalangeal joint arthrodesis is presented. The patient initially underwent cross-screw fixation for the treatment of hallux rigidus that resulted in joint infection and hardware loosening. A staged surgical approach was undertaken by means of initial hardware removal with implementation of an antibiotic cement spacer followed by revision arthrodesis with interposition of tricortical iliac crest autograft. This case report aims to highlight an accepted surgical approach to address an infected nonunion at the level of the first metatarsophalangeal joint.
Acral lentiginous melanoma (ALM) is a disease that is found on the palms, soles, and nail beds. Because these areas are not often examined during general medical examinations, the presence of ALM often goes unnoticed or the diagnosis is delayed. Research shows that the misdiagnosis of ALM is common, reported between 20% and 34%. We present three cases of ALM that were initially misdiagnosed and referred to the senior author (B.C.M.) in an effort to assess why misdiagnosis is common. The existing literature illuminates clinical pitfalls in diagnosing ALM. The differential diagnosis of many different podiatric skin and nail disorders should include ALM. Although making the correct diagnosis is essential, the prognosis is affected by the duration of the disease and level of invasiveness. Unfortunately, most of the reported misdiagnosed cases are of a later stage and worse prognosis. This review highlights that foot and ankle specialists should meet suspect lesions with a heightened index of suspicion and perform biopsy when acral nonhealing wounds and/or lesions are nonresponsive to treatment.
