Hypocalcemic-induced tetany that causes triceps and bilateral quadriceps tendon ruptures.

Traumatic ruptures of the triceps are very rare among tendon injuries. A unique case of hypocalcemic tetany that induced spontaneous triceps tendon avulsion with associated bilateral quadriceps tendon ruptures is reported. The current orthopaedic literature is reviewed, and a new application of an existing surgical treatment for repair of the major tendon ruptures is described.
