Procedure

Endoscopic lateral recess decompression is an ultra-minimally invasive technique designed to relieve nerve pressure caused by a specific form of spinal stenosis, where the central canal remains open but the lateral recess compresses the traversing nerve root. This often-overlooked pathology is a common cause of unilateral or bilateral radiculopathy. By utilizing the interlaminar corridor, surgeons can precisely remove compressive bone and tissue with minimal disruption to surrounding anatomy. Patients typically experience significant pain relief and improved mobility shortly after surgery.1 Long-term studies suggest these benefits are durable, with low reoperation rates.2

Child (D)

An endoscopic approach to medial branch nerve transection can lead&nbsp;to relief from pain caused by facet joint arthropathy. Combining 4K visualization&nbsp;with minimally invasive techniques allows surgeons to&nbsp;view and treat the spinal pathology while maintaining surgical precision&nbsp;and reducing postoperative complications.1,2

Medial Branch Transection

Minimally invasive endoscopic cervical foraminotomy and decompression is designed to treat cervical radiculopathy and other conditions that compress the nerve root. Utilizing an endoscope, surgeons can directly visualize and remove compressive pathology such as disc herniations, osteophytes, and hypertrophic ligaments. This technique minimizes soft-tissue disruption, reduces blood loss, allows for quicker recovery, and has demonstrated high clinical success rates, with a systematic review reporting 91.3% overall and up to 94.2% for posterior approaches.1,2 Additionally, long-term follow-ups show lasting symptom relief, high patient satisfaction, and a lower risk of adjacent segment disease compared to traditional ACDF surgery.3
Potential applications include treatment of cervical radiculopathy, herniated cervical discs, cervical spondylosis, foraminal stenosis, and osteophytes (bone spurs). Research supports its effectiveness in treating both soft disc herniations, where the nucleus pulposus compresses the nerve root, and hard disc herniations caused by calcified disc material.4 A lower incidence of spinal instability has also been reported, suggesting a reduced need for future spinal fusion procedures.5
Careful patient selection is key to optimal surgical outcomes; those with major deformity, instability, or large central herniations may require alternative surgery. With proper selection and advancing technology, this method remains a safe, effective, and motion-preserving option for cervical nerve decompression.1
