Meticulous attention to wound closure in posterior lumbar spine surgery is an important principle in reducing surgical site infections. We detail standardized wound closure used for posterior lumbar spine surgery at a tertiary care referral center and illustrate this as a step-by-step cadaveric dissection. The lumbar spine of a cadaveric specimen (male, 73 years at death) was used for dissection. Standardizing wound closure in posterior lumbar spine surgery may help limit wound complications and infection. Some key points of our technique, as demonstrated on a cadaveric specimen, include separating fascial compartments, avoiding suture abscesses, and creating a tension-free wound.

Is There An Optimal Wound Closure Technique For Major Posterior Spine Surgery? A Systematic Review., Emre Yilmaz, Ronen Blecher, Marc Moisi, Chandra Ankush, Thomas M O'Lynnger, Amir Abdul-Jabbar, Joseph R Dettori, Rod J Oskouian

Articles, Abstracts, and Reports

Study Design: Systematic review.

Objectives: In patients undergoing posterior spinal fusion: (1) What are the types and risks of wound complications in major (≥3 levels) surgery, and does the risk vary by number of levels fused? (2) What types of fascial closure result in the fewest wound complications? (3) What subcutaneous closure technique is more effective in preventing wound complications for obese patients (body mass index >30 kg/m

Methods: Electronic databases and reference lists of key articles were searched from January 1, 2000 to December 4, 2017 to identify studies meeting inclusion criteria.

Results: Six lower quality retrospective studies (evidence …

Anatomical Study Of The Extreme Lateral Transpsoas Lumbar Interbody Fusion With Application To Minimizing Injury To The Kidney., Joe Iwanaga, Emre Yilmaz, Tamir Tawfik, Amir Abdul-Jabbar, Marc Vetter, Marc Moisi, Koichi Watanabe, Koh-Ichi Yamaki, R Shane Tubbs, Rod J Oskouian

Articles, Abstracts, and Reports

Objective Since the extreme lateral lumbar interbody fusion procedure was first reported by Ozgur in 2006, a large number of clinical studies have been published. Anatomical studies which explore methods to avoid visceral structures, such as the kidney, with this approach have not been examined in detail. We dissected the retroperitoneal space to analyze how the extreme lateral transpsoas approach to the lumbar spine could damage the kidney and related structures. Methods Eight sides from four fresh Caucasian cadavers were used for this study. The latissimus dorsi muscle and the thoracolumbar fascia were dissected to open the retroperitoneum. The fat …

Risks Of Colon Injuries In Extreme Lateral Approaches To The Lumbar Spine: An Anatomical Study., Emre Yilmaz, Joe Iwanaga, Marc Moisi, Ronen Blecher, Amir Abdul-Jabbar, Tamir Tawfik, Rod J Oskouian, R Shane Tubbs

Introduction
 The extreme lateral interbody fusion technique (XLIF) is a modification of the retroperitoneal approach to the lumbar spine. This is a minimally invasive technique allowing direct access to the disc space without peritoneal or posterior paraspinal musculature damage. Nevertheless, the retroperitoneal part of the colon can be injured in this operative technique. To our knowledge, a study analyzing the anatomical considerations of the extreme lateral interbody fusion technique with regards to potential colon injuries has not been previously performed. Therefore, the aim of this study was to evaluate the potential risk of colon injuries during the extreme lateral approach …
