[[Nerve root]] compression was evident in twenty-one of the 100 foramina, in eight of the ten foramina in which the posterior [[disc height]] was four millimeters or less, and in four of the five foramina in which the foraminal height was fifteen millimeters or less. These critical dimensions may be indicators of foraminal stenosis in the lumbar spine. However, compression of a spinal nerve root does not always cause sciatica, and the clinical findings must always be taken into account when a diagnosis of stenosis is considered
