Surgical Outcome of Percutaneous Endoscopic Interlaminar Lumbar Discectomy for Highly Migrated Disc Herniation.
Technical report. ⋯ PEID may be applied comfortably even for less-experienced surgeons because of the familiar anatomy with open surgery.

Single Stage Anterior Release and Sequential Posterior Fusion for Irreducible Atlantoaxial Dislocation.
A retrospective study. ⋯ The method of single-stage anterior release and reduction with posterior fusion is an effective method for management of IAAD, proving its value as a technique for achieving complete reduction with solid bony fusion.

Preoperative Nutritional Status as an Adjunct Predictor of Major Postoperative Complications Following Anterior Cervical Discectomy and Fusion.
Retrospective analysis of the National Surgical Quality Improvement Program (NSQIP), a prospectively collected multicenter surgical outcomes database. ⋯ In this analysis of a prospective surgical outcomes database, preoperative serum hypoalbuminemia was an important adjunct predictor of major complications following ACDF. In high-risk patients with multiple medical comorbidities, we recommend that clinicians consider nutritional screening and optimization as part of preoperative risk assessment.

PEEK Versus Ti Interbody Fusion Devices: Resultant Fusion, Bone Apposition, Initial and 26 Week Biomechanics.
Comparative evaluation of in vitro and in vivo biomechanics, resulting fusion and histomorphometric aspects of polyetheretherketone (PEEK) versus titanium (Ti) interbody fusion devices in an animal model with similar volumes of bone graft. ⋯ Although material properties and surface characteristics resulted in differing amounts of biological integration from the host, both implants were capable of producing excellent fusion results using similar volumes of bone graft.

Cost-Utility Analysis of Instrumented Fusion Versus Decompression Alone for Grade I L4-L5 Spondylolisthesis at 1-Year Follow-up: A Pilot Study.
Retrospective 1-year cost-utility analysis. ⋯ Decompression without fusion is cost-effective for patients with grade I L4-L5 spondylolisthesis. Decompression with fusion is not cost effective in a 1-year timeframe for these patients based on the threshold. Accordingly, although fusion is beneficial for improving health outcomes in patients with spondylolisthesis, it is not cost-effective when analyzing a 1-year timeframe based on the threshold. The durability of these results must be analyzed with longer term cost-utility analysis studies.
