Distal biceps tendon ruptures are rare injuries that usually occur in middle-aged men. Most of these injuries are repaired acutely to restore preinjury function and strength. There is concern regarding the higher prevalence of certain complications with the double-incision technique. As such, the single-incision technique has also been studied to determine if it may produce superior safety and efficacy. In addition, the point of fixation may be created with either a rigid or a flexible reamer. The authors describe a technique that uses a single-incision cortical fixation achieved with a flexible reamer.
