Achilles tendon rupture as a result of oral steroid therapy.

Spontaneous Achilles tendon rupture associated with long-term oral steroid use is not uncommon, particularly in older patients who use these drugs daily to treat systemic diseases. Rupture often results in a large defect, which complicates surgical repair. The authors review Achilles tendon rupture associated with systemic and local steroid use and present a case of rupture due to chronic oral steroid use in a patient with Addison's disease.
