Ergonomics in Spine Surgery: A Systematic Review

Abstract

Study design: This study is a systematic review.

Objective: This systematic review aims to synthesize existing studies and highlight the significance of ergonomic considerations for spine surgeons' well-being and the impact on patient outcomes.

Summary of background data: Spine surgery is a physically demanding field that poses several risks to surgeons, particularly with musculoskeletal disorders. Despite the well-documented consequences of musculoskeletal injuries endured by surgeons, surgical ergonomics in spine surgery has received limited attention.

Methods: Following PRISMA guidelines, a comprehensive literature search was conducted in PubMed and Embase. Studies focusing on surgeon ergonomics in spine surgery were selected. Data extracted included study details, surgeon demographics, ergonomic factors, and outcomes. Qualitative analysis was performed due to the heterogeneous nature of study designs and criteria.

Results: Eleven studies met the inclusion criteria. Six studies utilized surveys to explore physical challenges, prevalence rates of pain, work practices, and ergonomic tools. Two studies employed optoelectronic motion analysis to assess the spinal angles of the surgeon during surgery. Two studies assesed ergonomics in different visualization methods using rapid entire body assessment (REBA). One study applied video analysis to scrutinize surgeons' neck postures during the case. The results demonstrated a varying prevalence and diverse presentations of musculoskeletal disorders, varying impact on surgical performance, and nuanced relationships between experience, workload, and ergonomic concerns.

Conclusion: This systematic review summarizes the heterogeneous evaluations of ergonomics in spine surgery. Overall, upwards of three-quarters of spine surgeons have reported musculoskeletal discomfort, most commonly presented as back pain, neck pain, and hand/wrist discomfort. These symptoms are often exacerbated by the use of loupes, operating bed height, and extended periods of time in various positions. Studies demonstrate that physical discomfort is associated with the surgeons' mental and emotional well-being, leading to stress, burnout, and reduced job satisfaction, all of which impact patient care.
