Contralateral Keyhole Biportal Endoscopic Surgery for Ruptured Lumbar Herniated Disc: A Technical Feasibility and Early Clinical Outcomes.

Objective: Spinal endoscopic surgery is increasingly adapted as a minimal invasive technique, however, significant facet joint violation may be developed after ipsilateral laminectomy. The aim of this study is to introduce surgical technique of contralateral keyhole biportal endoscopic surgery (CKES) for ruptured lumbar disc and report it is early surgical outcomes with facet joint violation.

Methods: Between January to December 2019, 27 patients with ruptured lumbar disc were underwent CKES.

Contralateral Interlaminar Keyhole Percutaneous Endoscopic Lumbar Surgery in Patients with Unilateral Radiculopathy.

Objective: Percutaneous endoscopic surgery is increasingly used as an alternative to open microsurgery for treating lumbar spinal diseases. The purpose of this study was to determine the feasibility and efficacy of contralateral keyhole endoscopic surgery for treating unilateral radiculopathy.

Methods: We performed percutaneous endoscopic sublaminar decompression via the contralateral interlaminar approach in 14 patients with unilateral radiculopathy.

Minimally invasive anterior lumbar interbody fusion followed by percutaneous translaminar facet screw fixation in elderly patients.

Object: The purpose of this study was to determine whether anterior lumbar interbody fusion (ALIF) followed by percutaneous translaminar facet screw fixation is effective in elderly patients with degenerative spinal disease.

Methods: Twenty-nine patients > 60 years old who underwent ALIF with percutaneous translaminar facet screw fixation from January to June 2004 were studied. The radiological and clinical data of these patients were collected and analyzed.

Percutaneous endoscopic lumbar discectomy for recurrent disc herniation: surgical technique, outcome, and prognostic factors of 43 consecutive cases.

Study Design: A retrospective study of 43 consecutive patients who underwent percutaneous endoscopic lumbar discectomy for recurrent disc herniation.

Objectives: To evaluate the efficacy of endoscopic discectomy for recurrent disc herniations and to determine the prognostic factors affecting surgical outcome.

Summary Of Background Data: Repeated open discectomy with or without fusion has been the most common procedure for a recurrent lumbar disc herniation.

Posterolateral percutaneous endoscopic lumbar foraminotomy for L5-S1 foraminal or lateral exit zone stenosis. Technical note.

The purpose of this study was to determine the efficacy and feasibility of posterolateral percutaneous endoscopic lumbar foraminotomy (PELF) for foraminal or lateral exit zone stenosis of the L5-S1 level in the awake patient. Twelve consecutive patients with L5-S1 foraminal stenosis and associated leg pain underwent PELF between May 2001 and July 2002. Under fluoroscopic guidance, posterolateral endoscopic foraminal decompression was performed using a bone reamer, endoscopic forceps, and a laser.
