| 1 | Prevalence and factors of work-related musculoskeletal disorders among hand surgeons显示文摘BACKGROUND The nature of tasks required by hand surgeons require both forceful and repetitive maneuvers,thus subjecting these surgeons to the risk of musculoskeletal(MSK)injuries during their years in practice.AIM To assess the prevalence,characteristics and impact of MSK disorders among hand surgeons.METHODS A modified version of the physical discomfort survey was sent to surgeons who were members of the American Society for Surgery of the Hand via e-mail.The collected data were analyzed using descriptive statistics,one-way analysis of variance,and Fisher’s exact test.P values of<0.05 were considered statistically significant.RESULTS Of the 578 respondents,60.4%reported that they had sustained a work-related MSK injury,of which the most common diagnoses were lateral elbow epicondylitis(18.7%),low back pain(17.1%)and carpal tunnel syndrome(15.6%).Among those that reported an injury,73.1%required treatment and 29.2%needed time off work as a direct result of their injury.The number of work-related injuries incurred by a surgeon increased significantly with increasing age(P<0.003),increasing years in practice(P<0.001)and higher case load(P<0.05).CONCLUSION To our knowledge this study is the first of its kind to assess MSK injuries sustained by Hand surgeons with a high incidence.These results should increase awareness on this aspect and fuel future studies directed at preventing these types of work-related injuries,thus minimizing the financial and psychological burden on these surgeons and the healthcare system. | Saad M Alqahtani Mohammad M Alzahrani Ryan Bicknell David Pichora | 2022 | World Journal of Orthopedics2022，13，5： | 2 |

| 4 | Work-related musculoskeletal injuries among upper extremity surgeons:A web-based survey显示文摘BACKGROUND Work-related injuries have gained recent attention,especially in the orthopaedic literature.As upper extremity orthopaedic surgical tasks require repetitive and constant maneuvers,these surgeons can be at increased risk of acquiring workrelated musculoskeletal(MSK)disorders during their years in practice.AIM To assess the prevalence,characteristics and impact of MSK disorders among upper extremity orthopaedic surgeons.METHODS A modified version of the physical discomfort survey was sent to surgeons who were members of the American Shoulder and Elbow Surgeons and the Canadian shoulder and elbow society via e-mail.The collected data were analyzed using descriptive statistics,one-way analysis of variance,and Fisher's exact test.P values of<0.05 were considered statistically significant.RESULTS Of the 142 respondents,90.8% were males and the majority were younger than 55 years old(65.5%).A work-related MSK injury was reported by 89.4% of respondents,of which the most common diagnoses were low back pain(26.1%)and lateral elbow epicondylitis(18.3%).Among those that reported an injury,82.7%required treatment and 26% required time off work as a direct result of their injury.The need to undergo treatment due to the injury was associated with increased number of injuries(P<0.01).Moreover,surgeons were more likely to require time off work when they had been in practice for>21 years(P<0.05).CONCLUSION A high proportion of surgeons in our survey reported MSK injuries,with more than one quarter of surgeons reported requiring time off work due to an MSK injury.The high incidence of these disorders may place a financial and psychological burden on surgeons and affect their ability to provide patient care.Awareness of operative ergonomics,irrespective of surgical specialty may help to decrease or possibly prevent the occurrence of these disorders. | Mohammad M Alzahrani Saad M Alqahtani David Pichora Ryan Bicknell | 2021 | World Journal of Orthopedics2021，12，11： | 1 |
