Open Reduction Internal Fixation
Open Reduction Internal Fixation (ORIF) is a correction and alignment of fracture after surgical dissection and exposure of the fracture. It does so by usage of metal screws, plates, wires, nails and pins to stabilize the fracture. Diagnosis of a fracture usually occurs in the ER. Diagnostics include X-rays, CT scans, and MRIs.
Here is a good short informative video that explains what an ORIF is.
