Lumbar nerve root compression by synovial cysts of the ligamentum flavum. Report of four cases

J Neurosurg. 1984 Mar;60(3):617-20. doi: 10.3171/jns.1984.60.3.0617.

Abstract

Synovial cysts of the ligamentum flavum, measuring 1 cm in diameter, caused compression of the lumbar nerve roots in four patients. The authors discuss the association of these cysts with advanced focal spondylosis, and speculate on their etiology.
