In this instance, disease of the dorsal
articular facets predisposes to hypertrophy of the associated joint capsule and ligaments, resulting also in spinal cord compression.
In this surgery
the articular facets (where the two vertebrae connect) are removed, as is the vertebral bone adjacent to the spinal cord.
Pediculectomy Similar to hemilaminectomy except only
the articular facets are preserved.
These include vertebral malarticulation / malformation, disk extrusion,
articular facet hypertrophy, and ligament hypertrophy.
