Harrington rod
Pronunciation: HAIR-ing-ton rahd
A historical spinal instrumentation system using distraction rods for scoliosis correction, largely superseded by modern systems.
Full Definition
Harrington rods were among the first widely used spinal instrumentation systems, developed by Dr. Paul Harrington in the 1960s for scoliosis correction. The system utilized stainless steel distraction rods attached to hooks placed on laminae or transverse processes to correct spinal deformity through distraction forces. While revolutionary for its time, Harrington instrumentation had significant limitations including loss of lumbar lordosis, frequent pseudarthrosis, and flatback syndrome. The system has been largely replaced by modern pedicle screw-based constructs that provide better three-dimensional correction and segmental fixation.
