The Impact of a Robotic Digital Microscope on the Ergonomics in a Neurosurgical Operating Theatre (A Single-Centre Experience).

Abstract

Ergonomics is an emerging concept in the neurosurgical operating theatre, where neurosurgeons work under great concentration and frequently neglect their uncomfortable body posture. Work-related musculoskeletal disorders (WMSD) are becoming a widespread burden in the neurosurgical community. WMSD have a negative impact on surgical performance and decrease the surgeons' quality of life. Here we present our single-centre 2-month experience with the Aesculap AEOS® Robotic Digital Microscope (RDM) and prospectively calculate the REBA (Rapid Entire Body Assessment) scores and compare them with similar neurosurgical cases operated with a conventional operative microscope (OPMI).Materials and Methods: For a period of 2months at the Department of Neurosurgery of the University Hospital Pirogov, Sofia, Bulgaria, 41 consecutive patients were operated on using RDM. The REBA employee assessment worksheets were filled in prospectively to assess the ergonomics of the senior author (N.G.) while using the RDM and the OPMI.Results and Conclusion: The ergonomics during neurosurgical operations could be substantially improved with the implementation of the exoscope. For challenging cranial approaches, where the operator must frequently "look around corners" the exoscope has a major advantage compared with the OPMI-the REBA score is 2.6 times lower for the exoscope and reaches a low risk for WMSD. For spinal operations, the neck score as part of the REBA score is three times lower for the exoscope.
