Open Reduction and Internal Fixation (Arm)

What Is Radius and Ulna Fracture—Internal Fixation Surgery?

Radius and ulna fracture repair via internal fixation surgery is one of the most popular methods for mending fractures in the forearm.  After administering general anesthesia, the surgeon makes one incision along the side of the forearm in line with the little finger and another along the underside of the arm (palm side up).  After positioning the bone ends, the surgeon attaches steel plates to them using screws.  A thin plastic drainage tube is put in place for 1 to 2 days to drain any residual blood before stitching up the wounds.  Patients usually remain hospitalized for 1 to 2 nights post surgery.   

Patients in need of internal fixation surgery for radius and ulna fractures can often receive it within 24 hours of injury.  The bones cannot be left to heal on their own since they typically do not heal in the correct position, which then restricts the patient’s movement.  Radius and ulna internal fixation is different from external fixation, where a rod is attached to the bone through the skin.   

After the procedure, the patient’s arm is held in a sling and raised to reduce swelling.  Painkillers help to reduce discomfort during the recovery period.  The patient can have the stitches removed after 10 to 12 days.  Patients are typically unable to drive or play sports for 6 weeks post surgery, but can resume light work within 3 to 4 weeks.  Manual laborers may be unable to work for 2 to 3 months.  Full recovery typically takes up to 6 months.  If necessary, a second operation takes place after 18 months to remove the metalwork.  Generally, the plates and screws are left in place permanently unless the patient plays high-level contact sports. Â
