Bertolotti’s syndrome is a spinal disorder characterized by abnormal enlargement of the transverse process of the most caudal lumbar vertebra. Pseudoarticulation between the transverse process of L5 and the alar of the sacrum can cause buttock pain and leg pain. A total 50 patients were selected as pure L5 transverse processectomy. The patient’s mean visual analogue scale (VAS) was 7.56±0.89 and postoperative VAS was 3.41±1.84. According to Macnab's criteria, 9 patients showed excellent results, and 27 patients showed good result, 8 patients showed fair, 2 patients showed poor results.
