cross-linking
Horizontal connector rods used to enhance spinal construct stability and prevent rotation.
Full Definition
Cross-linking refers to the use of transverse connector rods or cross-links placed between parallel longitudinal rods in spinal instrumentation systems. These connecting elements provide additional rotational stability, prevent rod migration, and enhance the overall rigidity of the construct. Cross-links are particularly important in long-segment fusions, deformity corrections, and cases where rotational control is critical. Modern systems offer various cross-link designs including fixed-length and adjustable connectors to accommodate different anatomical configurations.
Usage
Usage note: Specify number and location of cross-links in operative reports.
