Obesity and Self-reported Outcome after Minimally Invasive Lumbar Spinal Fusion Surgery

Abstract

Among this cohort of minimally invasive lumbar fusion patients, body habitus measured by BMI, weight, or height did not have a significant relationship with most self-reported outcome measures, operative time, length of hospital stay, or complications. Obesity should not be considered a contraindication to minimally invasive lumbar spinal fusion surgery.

Does Obesity Affect the Surgical Outcome and Complication Rates of Spinal Surgery? A Meta-analysis

“…Of all the included studies, eight [2,8,9,13,16,27,34,43] were prospective and 24 were retrospective studies. All but five studies were conducted in the United States; two were from China [10,11] and one each was from Israel [9], Sweden [16], and Austria [35].…”

The effect of obesity on patient-reported outcome measures after minimally invasive transforaminal lumbar interbody fusion

“…MIS techniques also pose several potential advantages for use in obese patients in terms of decreased incision length, blood loss, operative time, hospital stay and post-operative pain where abundant subcutaneous adipose tissue may necessitate a larger incision and dissection for adequate exposure when utilizing a traditional open approach. These advantages have been validated in several studies [3,34,35].…”

“…Additionally, obese patients that were managed operatively demonstrated significantly less improvement and lower final follow up values in the Sciatica Bothersomeness and Low Back Pain Bothersomeness Indices [42]. Though seemingly at odds with other clinical studies [12,20,[34][35][36], this as-treated analysis of the SPORT study has the benefit of a prospective design with large samples from multiple geographic locals and medical centers and long-term follow up which affords favorable generalizability of its results to true values expected in clinical practice.…”

“…In several of these studies, it has been shown that MI-TLIF results in improved clinical outcomes from baseline [3,34,35]. Andreshak et al examined a multitude of lumbar procedures (Microdiscectomies, laminectomies and fusions) and found no difference in clinical outcomes, operative time, blood loss or length of stay between obese and non-obese patients [36].…”

SENDS-Kriterien als Entwicklungstheorem der MAST‑Prozeduren

“…Ein Abschieben der Muskulatur mit Schädigung der Innervation ist nicht notwendig. Bei beleibten Patienten bringe das erhebliche Vorteile, berichten Rosen et al [23]. Spinale Navigation erleichtert die perkutane Implantation von Pedikelschrauben auch bei der Skoliose [21].…”
