Distal Humerus Open Reduction Internal Fixation

There have been considerable advances in the treatment of distal humerus fractures that allow for better outcomes. The widespread use of computed tomography helps surgeons preoperatively plan the method of fixation best suited for each patient. Modern fixation techniques are designed to improve mechanical stability of the construct through pre-contoured periarticular plates and the use of interlocking screws, or screws that lock into the plates.

These designs allow for better fixation and improved stability in fractures that are often comminuted or have pre-injury poor bone quality. These improvements in fixation have resulted in a decreased rate of hardware failure and nonunion, however the range of motion of the elbow is not reliably restored in every patient. The goal of surgery in distal humerus fractures is to achieve a stable fixation that allows for early unprotected range of motion to prevent the commonly encountered elbow stiffness.

Evolution of Procedure

Distal Humerus Fracture Surgery

The procedure most commonly performed for humerus fractures is open reduction internal fixation. This type of fixation includes utilizing plates and screws to approximate the broken bones together so the body can heal the injury faster and with the correct alignment. The location of the injury dictates the surgical approach utilized.

Once the surgeon is able to visualize the two ends of the broken bone, they use removable clamps or wires to hold the bone together in appropriate alignment. The fracture is then fixed utilizing basic principles of fracture fixation known to all orthopaedic surgeons. The plate and screws used to hold the bone together will remain within the body for life and are seldom removed.
