Bilateral rupture of the Achilles tendon in patients on steroid therapy.

Three patients are presented who sustained bilateral rupture of the Achilles tendon while on systemic steroid therapy for chest disease; a fourth patient with polymyalgia rheumatica on steroids is also presented. This is further evidence that tendon rupture can be a direct complication of steroid treatment. The English-language literature on bilateral Achilles tendon rupture is reviewed.
