Osteonecrosis en calcáneo en paciente con síndrome antifosfolípido

Abstract

IntroductionAlthough antiphospholipid syndrome (APS) is a well-known condition, certain manifestations of the syndrome such as osteonecrosis (ON) secondary to thrombotic events have been under-diagnosed. Avascular necrosis is the most common orthopedic complication. Case reportA 29 year-old man with a 13 month-course of pain in the right heel, without trauma, and with a personal history including antiphospholipid syndrome. In the imaging tests, ON in calcaneus is observed. On examination, multiple hemorrhagic macular painful lesions can be observed on the outer face of the foot up to the heel. The rest of the study examination is normal. He was treated with magnetic field therapy, with improvement of the symptoms. DiscussionOrthopedic manifestations of APS are relatively new and little known. It seems important to consider this condition in patients with APS and musculoskeletal pain in the absence of trauma, because cases have been reported where this autoimmune disease debuts with a fracture of the foot.
