Endoscopic Treatment of Lumbar Degenerative Disc Disease: A Narrative Review of Full-Endoscopic and Unilateral Biportal Endoscopic Spine Surgery.

Background: Degenerative lumbar spine disease is the leading cause of disability and work absenteeism worldwide. Lumbar microdiscectomy became the standard treatment for herniated discs and stenotic disease. With the evolution of different techniques, endoscopic spinal surgery emerged to minimize the surgical footprint while providing at least non-inferior results.

How I do it: the biportal endoscopic inclined-ipsilateral technique to decompress the lumbar lateral recess.

Background: Various full-endoscopic techniques have been developed to reach the lateral recess of the lumbar spine. However, specialized surgical tools, including expensive spinal endoscopic systems, and a steeper learning curve to mastering the technique are required.

Method: We present a novel target-addressed unilateral biportal endoscopic technique to reach directly the lumbar lateral recess, particularly useful at L4-L5 and L5-S1.

How to deal with this complication: Intraoperative anterior cage migration in L5-S1 resolved with a lumbar hybrid fusion technique.

Anterior cage migration is the most infrequent and dangerous complication seen in posterior lumbar interbody fusion (PLIF) procedures. We report the case of a 74-year-old woman who underwent PLIF at the L5-S1 level. During the surgery, one of the PLIF-cages dislodged anteriorly into the abdominal cavity without vascular injury.

Unilateral Biportal Endoscopic-Guided Transcorporeal Vertebroplasty with Neural Decompression for Treating a Traumatic Lumbar Fracture of L5.

Background: Lumbar burst fractures (complete or incomplete) of L5 have a low incidence, accounting for 1.2% of all spinal burst fractures. Treatment for these fractures remains controversial.

Ten-Step Biportal Endoscopic Transforaminal Lumbar Interbody Fusion Under Computed Tomography-Based Intraoperative Navigation: Technical Report and Preliminary Outcomes in Mexico.

Background: The principal advantage of intraoperative spinal navigation is the ease of screw placement. However, visualization and the integration of navigation can be explored with the use of navigation-guided full-endoscopic techniques.

Objective: To describe the stepwise intraoperative navigation-assisted unilateral biportal endoscopic transforaminal lumbar interbody fusion (UBE-TLIF) technique and to present our preliminary results in a Mexican population.

Minimally Invasive Craniocervical Decompression for Chiari 1 Malformation: An Operative Technique.

Chiari malformation type 1 (CM-1) is an ectopia of the cerebellar tonsils below the foramen magnum that causes severe disability due to its neurologic symptoms. The treatment of choice for CM-1 is decompression of the craniovertebral junction (CVJ). In some patients only an extradural decompression by removing the atlanto-occipital ligament may be sufficient.

Treatment of spinal malignant fibrous histiocytoma, a case report and literature review.

Objective: To present a case of spinal malignant fibrous histiocytoma in the fourth lumbar vertebra that received treatment by an L4 spondylectomy and placement of intervertebral expander and posterior fixation.

Case Report: A 47-year-old male patient with no relevant history presented with lumbar pain of 2 months' evolution. Treated conservatively, with slight improvement in pain, the patient persisted with low back pain irradiation to pelvic members, predominantly left-sided, accompanied by weakness and claudication.

Microscopy-assisted interspinous tubular approach for lumbar spinal stenosis.

Various minimally invasive techniques have been reported as an alternative to conventional lumbar decompression. The major advantage of these minimally invasive procedures lies in their reduction of unnecessary exposure and tissue trauma. Our objective was to describe a minimally invasive procedure for lumbar spinal stenosis decompression by enlarging the lumbar interspinous space, approaching it with a tubular retractor, and assisting with microscopy.

A prospective clinical study comparing MI-TLIF with unilateral versus bilateral transpedicular fixation in low grade lumbar spondylolisthesis.

Background: Minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) has become one of the standard techniques for approaching ipsilateral decompression, anterior column fusion, and posterior stabilization. This procedure is usually accompanied by the placement of bilateral transpedicular screws in the corresponding segment. The purpose of this study was to evaluate the clinical efficacy of unilateral screw fixation compared with bilateral fixation in patients diagnosed with low-grade symptomatic lumbar spondylolisthesis who underwent an MI-TLIF technique.

[Spinal extradural arachnoid cyst: A case report and review of literature].

Background: Arachnoid cysts of spine are a very rare occurrence. The aetiology still remains unclear, but the most accepted explanation is the existence of areas of weakness in the spinal dura. Symptoms depend on the location in the spine.
