BackgroundMusculoskeletal pain is commonly described in surgeons. Research suggests that 21-60% of at-risk physicians may experience significant work-related pain in their back, shoulders, neck or upper extremity and the consequences of this may impact negatively on patient care. Laparoscopic surgery in particular has become increasingly associated with musculoskeletal pain, especially in the cervical spine. Due to a number of constraints, however, it is difficult to evaluate musculoskeletal movement (particularly cervical spine motion) in the operating room environment.Study DesignThree consultant general surgeons were fitted with an ambulatory strain gauge in an attempt to accurately measure and compare cervical motility during open and laparoscopic surgeries. Intraoperative figures pertaining to neck flexion, extension and rotation during forty surgical procedures were collected. The completed data consisted of twenty open and twenty laparoscopic procedures, and the results were compared.ResultsThere was a statistically significant reduction (21.38%) in measured neck movement in laparoscopic surgery when compared with open surgery p = 0.004 (Table 2). A standard deviation of 18.97 was computed for open surgery indicating a larger variability in results deviation from the mean when compared with a value of 8.92 for laparoscopic surgery. Mean rotational neck movement was also reduced during laparoscopic procedures (23.5%) when compared with open procedures (87.9%).ConclusionBased on our results, we believe that laparoscopic surgery requires more prolonged periods of static neck posture when compared with open surgery. This difference may assist in understanding the contributing factors for musculoskeletal (in particular cervical) pain encountered in minimally invasive surgeons. Further investigation of static posture in the operating surgeon is warranted.
