Study Design:
Case presentation.
Objective:
The interlaminar endoscopic lateral recess decompression (IE-LRD) represents a novel surgical alternative to consider in carefully selected cases, particularly when patients do not respond to conservative treatment.
Background:
Lumbar spinal stenosis (LSS) constitutes one of the most prevalent spinal conditions in the elderly population around the world. A myriad of causes have been elucidated, and although infrequent, vertebral compression fractures (VCF) may also cause LSS. Conservative treatment might be the first option; however, patients often require surgery.
Methods:
A 76-year-old woman with a medical history of dementia consulted for radicular pain in her left leg during the past 6 months, without any favorable response to conservative treatment. Neurological examination revealed a positive straight leg raising test on the left. A spine MRI revealed a VCF in L5, linked with spondylolisthesis (grade I) at L5-S1. An IE-LRD was planned, as the patient did not consent to a classical open surgery. The incision was placed over the inferior medial edge of the left L4 lamina. Following sequential dilatators, the working channel was located on the inferomedial edge of the left L4 lamina. Lateral fluoroscopy (LF) guided the entire procedure. During the procedure, laminotomy was extended cranially and caudally to ensure sufficient vertebral decompression.
Results:
After surgery, the patient was mobilized in the first 6 hours and discharged in the next 24 hours. Her lower back pain score improved significantly to 2-3, while her leg VAS pain improved to 0-1. After a follow-up for 18 months, the patient did not manifest complications or recurrences, and no additional treatment was carried out.
Conclusion:
(1) IE-LRD might be a useful and safe surgical procedure for the surgical management of LSS caused by VCF. (2) Consider this surgical alternative for elderly patients without a previous response to conservative medical treatment.
