Surgical interventions for Bertolotti's syndrome: case report and review of unsatisfactory cases in the literature.

BACKGROUND

Bertolotti's syndrome (BS) is characterized by the enlargement of transverse processes in caudal lumbar segments, causing chronic and persistent low back pain or sciatica. The present study aimed to describe our surgical technique for BS treatment and to review existing literature describing unsatisfactory outcomes.

CASE PRESENTATION: We report a patient who complained of lower back pain and soreness that intermittently radiated to his left leg for longer than 10 years. Based on an examination of his symptoms and signs, including imaging and electrical physiology assessments, in addition to the report of temporary pain relief after a local steroid injection to a diagnostic trigger site (articulation between the transverse process and the sacral ala or iliac crest), the patient was diagnosed with BS. The applied surgical techniques included minimally invasive, three-dimensional C-arm guidance, a tubing approach, and microscopic and bone cavitron ultrasonic surgical aspirator-assisted operations. After surgery, improvements were reported on the visual analog scale (from 8 to 2 points on a 10-point scale) and the straight leg raising test for the left leg (20° to 90°) within 3 days. The patient gained an ordinary life and returned to work within one week of surgery, with no observed postoperative complications.

CONCLUSIONS

Minimally invasive tubular microscopic decompression and disarticulation is an effective method for treating BS. However, to achieve a successful outcome, it is recommended to use physician-proficient techniques that are in line with the patient's diagnosis.
