Correlation between inter-vertebral disc morphology and the results in patients undergoing Graf ligament stabilisation.

Background: Previous studies have shown Graf ligament stabilisation procedure to give mixed results in the short to medium term. The aim of this study was to correlate the pre-operative state of the disc, multifidus muscles, age of the patient, levels operated and the clinical outcome after a mean follow-up of 47 months.

Methods: Graf ligament stabilisation procedure was carried out in 38 patients between 1996 and 1999.
