Multilevel mini-open TLIFs and percutaneous pedicle screw fixation: description of a simple technical nuance used to increase intraoperative safety and improve workflow. Tips and tricks and review of the literature.

We describe a technical variation used to enhance intraoperative safety and efficiency in multilevel percutaneous pedicle screw fixation (PPSFs) and mini-open transforaminal lumbar interbody fusion (m-TLIFs). A review of the literature on percutaneous screw insertion techniques and related pitfalls is presented. PPSFs and m-TLIFs are increasingly used techniques in multilevel lumbar degenerative disease.

Bilateral tubular minimally invasive surgery for low-dysplastic lumbosacral lytic spondylolisthesis (LDLLS): analysis of a series focusing on postoperative sagittal balance and review of the literature.

Purpose: To report our early experience with minimally invasive surgery (MIS) in low-dysplastic lumbosacral lytic spondylolisthesis (LDLLS), and to analyze the impact of surgery on postoperative spino-pelvic and sacro-pelvic parameters.

Methods: Eight patients (mean age 47.6 years) underwent MIS for LDLLS involving in all but one the L5-S1 level.

Subphrenic hematoma after thoracoscopic discectomy: description of a very rare adverse event and review of the literature on complications: case report.

The authors describe a very rare and previously unreported complication of thoracoscopic discectomy. Endoscopic spine surgery has evolved as a safe and effective treatment, and thoracoscopic discectomy, in particular, provides several advantages over open approaches, although it can be associated with intraoperative or postoperative complications. The most frequently observed adverse events are intercostal neuralgia, retained disc fragments, durotomies, atelectasis, extensive bleeding, and emergency conversion to open thoracotomy for vascular injuries.
