Estimation of surgeons' ergonomic dynamics with a structured light system during endoscopic surgery

Area of Science:

• Surgical Ergonomics
• Musculoskeletal Disorders
• Medical Simulation

Background:

• Endoscopic sinus surgery involves complex procedures with potential ergonomic challenges.
• Surgeon posture and musculoskeletal strain are critical factors in surgical outcomes and well-being.
• The Rapid Upper Limb Assessment (RULA) tool is validated for assessing ergonomic risk.

Purpose of the Study:

• To evaluate surgeon posture during simulated endoscopic sinus surgery using motion capture.
• To analyze the ergonomic risk of musculoskeletal overload using the RULA tool.
• To compare the ergonomic impact of standing versus sitting positions for surgeons.

Main Methods:

• Simulated bilateral endoscopic sinus surgery on cadaver heads.
• Motion capture technology (Kinect) and .NET WPF software for postural data collection.
• Analysis of postural data using the Rapid Upper Limb Assessment (RULA) tool.

Main Results:

• All participants reported physical discomfort post-procedure.
• Similar RULA scores were observed between residents and practicing rhinologists.
• Sitting position showed a slightly lower overall RULA score, but increased risk for arm and upper back (Group A).

Conclusions:

• Both residents and specialists experience significant musculoskeletal symptoms after endoscopic surgery.
• High RULA scores indicate a substantial ergonomic risk for surgeons.
• Immediate ergonomic interventions are necessary to mitigate risks in endoscopic sinus surgery.
