Simultaneous Bilateral Quadriceps Tendon Rupture in a Patient with Diffuse Idiopathic Skeletal Hyperostosis after Minimal Trauma: Eight-Year Follow-Up

Abstract EN

Introduction.

The purpose of this report was to describe a very rare case of simultaneous bilateral quadriceps tendon rupture seen in a patient who was diagnosed as having diffuse idiopathic skeletal hyperostosis.

Case Presentation.

A man aged 64 years presented to the emergency department with bilateral quadriceps tendon rupture.

Surgical repair was performed with suture anchors and a stainless steel cable.

His legs were immobilized in casts for six weeks.

After removal of the casts, physiotherapy was started.

Four months after surgery, he was able to walk with 0°–120° range of motion and active extension.

He was followed up for 8 years without rerupture or other complications.

Conclusion.

Bilateral rupture of the quadriceps tendon is a rare condition and generally related to metabolic disorders.

Diffuse idiopathic skeletal hyperostosis is a metabolic disorder that causes bilateral quadriceps tendon rupture, and it accounted for the differential diagnosis of the underlying condition.
