Outcome-relevante Faktoren in der Wirbelsäulenchirurgie

Abstract

Several parameters might influence the outcome after vertebral spine surgeries. In order to find these a systematic literature search was performed. Thereby, a total of 62 articles were selected. All outcome-relevant parameters were categorized into patient-specific, course-specific, and radiologic parameters. Furthermore, scores were included which help to estimate the risk of adverse events and outcome for certain pathologies and/or surgeries. Patient-specific parameters were predominantly the patient age and several specific secondary diagnoses such as diabetes, adipositas, depression, anxiety disorders, and nicotine abuse. Additionally, the patient expectation plays an important role in the subjective outcome assessment. Course-specific parameters are mainly perioperative factors such as surgical experience, particularly in highly demanding vertebral spine surgeries. Furthermore, modern intraoperative equipment such as intraoperative CT and neuromonitoring helps to increase patient safety. The most outcome-relevant radiologic parameters are those which define the sagittal balance. Thereby, a correct sagittal balance is associated with superior clinical outcomes.
