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.
