Spontaneous and simultaneous rupture of both Achilles tendons in a haemodialysis patient.

This case involved a male patient in his 30s who sustained a spontaneous and simultaneous bilateral rupture of the Achilles tendons. His medical history was significant for end-stage renal failure for which he had been undergoing haemodialysis for 13 years, and parathyroidectomy 2 years before this presentation. The patient underwent an open repair of both Achilles tendons using gastrocnemius augmentation with a favourable final outcome. The radical control of secondary hyperparathyroidism in haemodialysis patients does not protect the patient from the occurrence of spontaneous tendon rupture in all cases.
