Outline
Text
Objective: Working place of spine surgeons in the operating room (OR) requires permanent standing occupation in a monotone constrained posture. The static load is often aggravated by burden of an X-ray lead gown. Working times in excess of 10 hours are not rare due to economic reasons. The ergonomic arrangement of the working place in the OR is therefore an important measure to improve and preserve capability and physical health for surgeons and assisting staff.
Methods: In a prospective, oligocentre observational study with N=30 participants evaluation was carried out, whether the use of a polyurethane foot mattress of 2 cm thickness would influence subjective capability and physical health. According to a standardized questionnaire, subjective parameters before, during and after the working process in the operating room were recorded. N=4 questionnaires with versus without use of a foot mattress of each study participant were analysed. Further, N=10 participants were included for anatomical and ergonomical evaluation. In addition, electronical plantar footprint measurement and optical pedobarography and gravity loading for each food were revealed by using a sensoric sole, which analysed 5-minute-standing and movements in a simulated working situation, comparable to reality in the OR.
Results: 83% of N=30, so in 120 consecutive questionnaires, participants reported a positive effect as well as an improvement of capability by using a polyurethane foot mattress independent of the duration of use. A reduction of weariness, leg pain and lower back pain was reported for use of a foot mattress in excess of 4 hours (p<0,05). Pedobarography for a 5-minute-simulation of standing and working in the OR revealed an improvement concerning centre of pressure in the analysed feed. The mean pressure was 26% lower with a significant improvement of P<0.05.
Conclusion: Ergonomic arrangement of the individual working place is an established matter of course according to the guidelines of workers compensation board. Working place of spine surgeons and operating staff leads to a wearing and constrained posture. The flexible standing position on a polyurethane foot mattress leads to a significant performance enhancement and improvement of physical health of the spine surgeon and the operation staff.
