Extensive heterotopic ossification after suspensory cortical fixation of acute distal biceps tendon ruptures.

Suspensory cortical fixation is commonly used for distal biceps tendon repair and reconstruction with one of several commercially available devices. The single-incision approach typically used with these devices is believed to have a lower incidence of heterotopic ossification than the dual-incision technique, but the true incidence of heterotopic ossification is unknown. The role of chemotherapeutic or radiation prophylaxis is undefined. We have identified 4 cases of extensive heterotopic ossification after biceps fixation with a suspensory button and single-incision approach. Surgeons should be aware of this potential complication when using suspensory cortical buttons for distal biceps fixation.
