Subarticular zone stenosis is a form of spinal stenosis where there is narrowing of the subarticular zone, including the lateral recess. This may occur with or without other forms of spinal stenosis.
Pathology
Nerve root compression at the lateral recess can occur in two morphological forms:
-
trefoil narrowing of the lateral recess
can be congenital or acquired
results from diminished anteroposterior dimension of the lateral canal
angular pinch-like encroachment of the lateral margin of the canal can lead to subsequent pinching of the nerve root
