OBJECTIVE
To compare the clinical outcomes of intrasacrospinal muscular approach and posterior midline approach in treating far lateral lumbar disc herniation.

METHODS
The clinical data of 32 patients with far lateral lumbar disc herniation underwent transforaminal lumbar interbody fusion from January 2004 to January 2011 were retrospectively analyzed. The patients were divided into intrasacrospinal muscular approach group (11 males and 6 females ) and posterior midline approach group (10 males and 5 females). All patients were followed up from 12 to 18 months with an average of 15.3 months. Operative time, blood loss, postoperative draining volume were recorded and pre-and post-operative visual analog scale (VAS) and Oswestry Disability Index (ODI) were compared between two groups.

RESULTS
Operative time, blood loss, postoperative draining volume in intrasacrospinal muscular approach group was less than that of posterior midline approach group (P < 0.05). There was no significant difference in VAS at final follow-up between two groups (P > 0.05); and the mean ODI in intrasacrospinal muscular approach group was less than that of posterior midline approach group (P < 0.05).

CONCLUSION
For the treatment of far lateral lumbar disc herniation, intrasacrospinal muscular approach has less injury for paraspinal muscle and more satisfactory clinical outcome and is better method than posterior midline approach.
