OBJECTIVE: A detailed investigation of the gross and microscopic anatomy of ligamentum flavum.
METHODS: Material included 14 lumbar vertebral columns obtained from the Anatomy Department, King Faisal University, Dammam during the period between January 2005 and January 2006. Height, width, and thickness of ligamenta flava were measured. A microscopic study was also performed. Computed tomography scan was carried out on the lumbar vertebrae of 30 patients for measuring the ligamentum flavum.
RESULTS: The anatomical results showed that the right and left ligamenta flava join in the midline forming an acute angle with a ventral opening. The ligamentum flavum is rectangular and has 4 borders and 2 surfaces. It is attached inferiorly to the superior edge and the postero-superior surface of the lamina below. It is attached superiorly to the inferior edge and the antero-inferior surface of the lamina above. Its height ranges from 14-22 mm. The width of its lower part ranges from 11-23 mm, and the thickness ranges from 3.5-6 mm. The histological results revealed that it is comprised chiefly of elastic fibres and some collagen fibres.
CONCLUSION: The information reported in this study is of clinical value in the practice of lumbar epidural anesthesia or analgesia. Epidural puncture will be best performed through the lower and medial portion of the ligamentum flavum slightly lateral to the midline.
