Procedure

The transforaminal endoscopic thoracic discectomy is a powerful approach for treating all types of thoracic disc herniations and, in recent studies, has been shown to minimize collateral damage, blood loss, postoperative pain, and spinal cord manipulation.1-4 This is the only approach that offers an unobstructed view of the ventral thoracic canal without extensive bony resection and without requiring entry into the thoracic cavity.&nbsp;

Transforaminal Endoscopic Thoracic Discectomy

Child (D)

The endoscopic approach to interlaminar discectomies provides minimally invasive access to posterior herniations in the lower lumbar spine that may be difficult to reach through a transforaminal approach. Additionally, interlaminar discectomy results in less tissue and muscle disruption, faster recovery times, and a quicker return to activity than traditional open procedures.1-4 WishBone™ endoscopic instruments feature superior feel and improved ergonomics that facilitate inverted and retrograde usage with either hand.

Interlaminar Endoscopic Discectomy

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

Lateral Recess Decompression

The traditional open approach for treating far lateral disc herniations at L5-S1 is challenging. Alternatively, the transforaminal endoscopic approach lands directly at the far lateral zone and requires little or no facet resection to achieve decompression.

Far Lateral Transforaminal Endoscopic Lumbar Discectomy

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

A transforaminal, or paraspinal, approach provides the ability to reach far-lateral disc herniations. Using a spine-specific endoscope minimizes soft-tissue disruption, resulting in less postoperative pain.1,2 Additionally, studies showed that approximately 85% patients who underwent endoscopic lumbar discectomy returned to athletic activity in as few as 6 to 8 weeks.3,4

Transforaminal Endoscopic Discectomy

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
