The Impact of Lead Aprons on Posture of Orthopaedic Surgeons

Abstract

Background Surgeons working in orthopedics and trauma surgery are frequently exposed to repetitive actions and non-ergonomic positions in their operative activities with the regular use of lead aprons. Musculoskeletal complaints of the neck and back among surgeons are reported in the literature as up to 80%. In this study, the effects of lead aprons on the posture of surgeons are examined using videorasterstereography, foot pressure measurement and questionnaires.

Methodology All subjects (n = 31) were examined before and after exposure to wearing lead aprons during surgery using videorasterstereography and pedography. In addition, a survey with a separately created questionnaire and the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) was carried out.

Results An average duration of lead apron use of 102.6 min showed an increase in forefoot load (p = 0.002) especially in the elderly subjects and thoracic kyphosis (p < 0.001) especially in the younger doctors with a significant lateral deviation (p = 0.006). In addition, the lateral deviation was shown to correlate with an increasing body size or a shorter period of employment (p = 0.008; r = 0.51/p = 0.026; r = − 0.44). Significantly fewer surgeons experienced back complaints on working days without lead apron use in the operating room compared to days in the OR (p = 0.011).

Conclusion The impact of wearing front covered lead aprons during operations in the field of orthopaedics and trauma surgery leads to more frequent back complaints, even among young and healthy doctors. Under an average duration of surgery of 102 min a temporary postural deviation occurs that can be demonstrated by means of videorasterstereography and foot pressure measurement. The subjects showed a shifted weight distribution on the forefoot, a gain in thoracic kyphosis and an increase in lateral deviation, which also correlated with an increasing height and shorter length of employment.
