Study Design. To use fresh, human supraspinal and interspinal ligaments and document their innervation. Objective. To characterize the innervation of the human supraspinal and interspinal ligaments. Summary of Background Data. The nature and distribution of the innervation of spinel ligaments remains unknown. Methods. Sections of spinel ligsrpants were labeled with a fluorescent antibody against neurofilament proteins and observed with a confocal microscope. Results. The liflaments were found to be well innervated. Innervation wa equally distributed along the ligament, symmetrically distributed between left and right sides, and more densely distributed in the periphery. Pacinian corpuscles were scattered randomly, close to blood vessels, whereas Ruffini corpuscles were in the periphery, close to the collagen bundles. Conclusions. Human supraspinal and interapinal ligaments are well innervated. This innervation might form the basis of neurologic feedback mechanisms for the protection and stabilily of the spine. These mechanisms might also be important the development of diseases such as scoliosis.
