[Achille's tendon rupture].

Achille's tendon rupture (A, B) involves a tendon with degenerative lesions that are asymptomatic until rupture. These degenerative lesions result from tendon microtraumas and overexertion almost always related to sport and hyperactivity as well as to tendon aging. Etiologic research is necessary in patients with Achille's tendon rupture. Favoring factors include morphological disorders (hollow foot; unequal length) while triggering factors include insufficient training, running on solid ground, poor shoe conditions. We here report the case of a 50-year old female patient with no particular past medical history with left Achille's tendon rupture (A) surgically treated (C, D) by Bosworth technique based on plaster-cast immobilization using plaster cast boot for 21 days. After two months of rehabilitation, functional recovery was complete. However, the etiological assessment showed early-stage systemic lupus erythematosus.
