Spontaneous bilateral rupture of quadriceps tendon: first case in short daily haemodialysis

Spontaneous bilateral rupture of quadriceps tendon in patients with chronic renal failure is a rare event. All patients reported until now had been on conventional haemodialysis three times a week. We report the first case of a patient on short daily haemodialysis (SDH) with hyperparathyroidism who refused surgical treatment. The serum alkaline phosphatase level had been increasing continuously until the day of tendon rupture. This report alerts about this diagnosis and also emphasizes the continuous increase in the serum alkaline phosphatase level prior to the tendon rupture. Even among well-dialysed patients, on SDH, spontaneous tendon rupture can occur.
