Decompression with or without concomitant fusion in lumbar stenosis due to degenerative spondylolisthesis: a systematic review.

PURPOSE: The primary objective of this systematic review is to compare the outcome after decompression with and without concomitant instrumented fusion in patients with lumbar stenosis and degenerative spondylolisthesis. Does adding fusion to simple decompression lead to better results? METHODS: PubMed, Embase, CENTRAL, Cochrane, Web of Science, CINAHL and Academic Search Premier were searched. All studies comparing outcome of decompression alone to decompression with concomitant-instrumented fusion in patients suffering from symptomatic lumbar stenosis with degenerative spondylolisthesis were included. Risk of bias was assessed using an adapted version of the Cowley checklist. RESULTS: Eleven studies were included in the analysis involving 3119 patients in total. In the majority of studies, including two RCTs, clinical outcome of both patient groups was comparable regarding most clinical outcome measures. CONCLUSION: Currently there is not enough evidence that adding instrumented fusion to a decompression leads to superior outcomes compared to decompression only in patients with lumbar stenosis and degenerative spondylolisthesis. The most important clinical outcome measures, including the ODI, show comparable results. Therefore, the least invasive and least costly procedure, being decompression alone, is preferred in patients with low-grade spondylolisthesis with predominant leg pain.

Management and outcome of burn injuries during pregnancy: A systematic review and presentation of a comprehensive guideline.

Pregnant women are a vulnerable subgroup of burn patients, due to altered physiological state and possible adverse effect on the fetus. The aim of this study was to develop a guideline for a tailored treatment of pregnant patients with burns to optimally treat both mother and fetus. This study consists of two parts: the first part contains a systematic review that presents a comprehensive overview of the literature on the management and outcome of pregnant women who sustain severe burn injuries and based on the results of this review, a guideline on the general, obstetric and burn management was developed and presented in the second part. A total of 35 studies including 1395 patients were included. Although the clinical outcomes seemed to be similar to non-pregnant patients, one study showed that mortality might be higher in the pregnant population. Predictive factors for maternal and fetal mortality were a total burned surface area of over 40% and inhalation injury. Early surgery may lead to a higher chance of survival of mother and fetus. A comprehensive guideline on the general management of pregnant patients with burns, obstetric management and specific burn management is provided. We encourage international burn organizations and guideline committees to use and evaluate the presented guideline.
