Abstract:
This report presents a unique case of checkrein deformities in both halluces following isolated intramuscular sarcoidosis, a rare occurrence given the infrequent musculoskeletal involvement in sarcoidosis. Typically resulting from flexor hallucis longus tendon entrapment by scar tissue post-trauma, the checkrein deformity reported in this paper presented with unusual metatarsophalangeal joint flexion and interphalangeal joint extension during ankle dorsiflexion. A 49-year-old woman with a history of intramuscular sarcoidosis presented with a great toe deformity and discomfort while wearing shoes, leading to a diagnosis of dynamic deformity, possibly attributed to tendon tethering by sarcoidosis. Surgical treatments, including abductor hallucis muscle intratendinous tenotomy, flexor hallucis longus Zplasty lengthening, Weil osteotomy, and Kirschner wire fixation, significantly improved the functional scores and patient discomfort.This report underscores the importance of recognizing dynamic deformities and the potential for rare diseases, such as sarcoidosis, to cause such conditions, highlighting the need for careful diagnosis and tailored surgical intervention for atypical checkrein deformities.
