Musculoskeletal disorders and discomfort for female surgeons or surgeons with small hand size when using hand-held surgical instruments: a systematic review.

BACKGROUND: Work-related musculoskeletal disorders (WMSDs), also referred to as work-related musculoskeletal injuries (MSKIs), cause surgeons pain and discomfort. Implementing ergonomics in the operating room has helped reduce such symptoms. However, there are still many issues that surgeons face when dealing with medical instruments, especially among female surgeons or surgeons with smaller hands. METHODS: The Cochrane methodology for performing a systematic review was utilized to search five databases for pertinent literature based on the study question "Do female surgeons or surgeons with smaller hand size, who use surgical instruments have an increased risk of musculoskeletal disorders and discomfort compared to male or larger handed surgeons?". The literature search strategy was designed around the three conceptual domains of surgeons/surgery, smaller hand size, and instrumentation. We searched PubMed, Embase.com, CINAHL Plus with Full Text (EBSCOhost), Scopus, and Web of Science Core Collection. This exploration identified 2165 research publications, and after specific inclusion and exclusion criteria, 19 studies were included in the systematic review. Risk of bias analysis was conducted to assess the quality of the included studies. After conducting a heterogeneity test, a meta-analysis was not performed due to high heterogeneity. RESULTS: Using certain surgical instruments presents challenges in the form of MSKIs for female and smaller-handed surgeons. Studies showed that 77% of females and 73% of surgeons who wear < 6.5 glove size report musculoskeletal issues ranging from difficulty of use to pain. Difficulties using surgical instruments and reported injuries have a greater impact on surgical trainees which might deter interest in surgical fields for future proceduralists. Recommendations for improved ergonomic tool design are suggested by some of the included studies to help tackle the MSKIs that surgeons face when performing operations. CONCLUSIONS: The number of female surgeons has increased substantially in the last decade. Hence, there exists an urgent need to address the major challenges they encounter by focusing on this specific aspect of workplace safety and health to mitigate injury. Doing so will yield a productive environment while simultaneously protecting the health and safety of both surgeons and patients. SYSTEMATIC REVIEW REGISTRATION: The study protocol was registered on PROSPERO (ID: CRD42022283378).

Don't Just Stand There. Rethinking the Ideal Body Posture for Otorhinolaryngologists.

Surgeons have a high rate of work-related musculoskeletal injuries; an area that has received little attention. These injuries result in surgeons performing less efficiently, needing to take time off work, suffering higher rates of burnout, and may ultimately lead surgeons to retire earlier than planned. Otorhinolaryngologists are at particular risk for work-related musculoskeletal injuries. Beyond the clinician, sustaining such injuries can negatively impact patient safety. Ergonomic interventions have been used effectively to reduce work-related musculoskeletal injuries in other professions, yet not in surgery. With traditional teachings of ideal body postures to avoid injury and manual handling training being re-evaluated, it is important to explore evidence based interventions for reducing work-related musculoskeletal injuries in otorhinolaryngologists. New research encourages us to shift the focus away from the traditional one-size-fits-all approach to ergonomics and toward postural recommendations and education that promote a dynamic, individualized approach to avoiding sustained, static and awkward postures.

Work-related diseases and risk factors associated with work-related musculoskeletal disorders among unionized metal industry workers: a cross-sectional study.

Objectives. This study aimed to determine the prevalence of work-related diseases (WRDs) and work-related musculoskeletal disorders (WR-MSDs), as well as investigate WR-MSD-associated risk factors, among metal industry workers in Turkey. Methods. The cross-sectional study was conducted with 1374 members of the Birlesik Metal Is Union from 121 companies. Data were collected using a self-administered 30-item questionnaire. Results. The survey response rate was 81.4% (1374/1686). Almost one out of every six workers (14.8%) stated that they had been diagnosed with a WRD, 3.6% reported that they had been diagnosed with an occupational disease and 38.6% of them indicated that they had suffered an occupational accident (OA) at least once. The prevalence of WR-MSDs was 10.7%, of work-related lung diseases was 1.8% and of occupational hearing loss was 0.6%. Quitting smoking, smoking, OA, heavy lifting, time pressure and working in the automotive industry were all associated with WR-MSDs. Conclusions. Interventions aimed at reducing musculoskeletal disorders (MSDs) should focus on smoking cessation, training workers in proper techniques and equipment for lifting and pushing/pulling heavy loads, preventing OAs and injuries, and reducing the time pressure in the workplace in the metal industry.

Work-related musculoskeletal disorders and related risk factors among bakers: A systematic review.

BACKGROUND: Work-related musculoskeletal disorders (WRMSDs) and ergonomic risk factors are very common in bakery workers. OBJECTIVE: The purpose of this study is to (1) assess the prevalence of musculoskeletal disorders among bakers because they use automated machines or traditional baking, and (2) to determine the strategies to prevent musculoskeletal disorders in bakers. METHODS: A systematic review of PubMed, Scopus, and Web of Science was conducted from the beginning to February 4, 2022, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Mesh keywords and phrases were used to execute the search strategy. Information on MSDs and ergonomic risk factors in bakery workers was collected. Two reviewers worked independently on study selection, data extraction, and paper quality ranking. RESULTS: This study identified 14 papers from seven countries. Although the prevalence of MSDs in bakery workers has been studied, only a handful of them have been studied ergonomic risk factors, and the findings have been very limited. The association between different risk factors and MSDs seemed significant compared to many other occupational diseases. The traditional bread-baking system and lack of mechanization may increase the risk of MSDs in bakery workers. CONCLUSION: WRMSDs for bakery workers have been less studied than other occupational diseases. Our systematic review found several significant relations between the factors influencing the prevalence of MSDs. This study also showed the comparison of traditional and modern cooking systems with diseases of the upper limbs, shoulders, and back pain as possible fields for future research.

The impact of procedural activities on musculoskeletal pain experienced by pregnant surgeons.

BACKGROUND: Two-thirds of surgeons report work-related musculoskeletal disorders (WRMD). There is limited data on WRMD symptoms experienced by pregnant surgeons. METHODS: We distributed an electronic survey via personal contacts to attending and trainee surgeons across six academic institutions to assess the impact of procedural activities and surgical ergonomics (SE) on WRMD symptoms during pregnancy. RESULTS: Fifty-three respondents were currently or had been pregnant while clinically active, representing 93 total pregnancies. 94.7% reported that symptoms were exacerbated by workplace activities during pregnancy and 13.2% took unplanned time off work as a result. Beyond 24 weeks of pregnancy, 89.2% of respondents continued to operate/perform procedures, 81.7% worked >24-h shifts and 69.9% performed repetitive lifting >50 pounds. No respondents were aware of any institutional pregnancy-specific SE policies. CONCLUSIONS: Procedural activities can exacerbate pain symptoms for the pregnant surgeon. SE best practices during pregnancy warrant further attention.

COVID-19 Marked a Change in the Scope of Occupational Medicine from Occupational to Work-Related Diseases and Total Worker Health®.

The COVID-19 pandemic challenged occupational medicine, while its focus had already shifted from occupational diseases to work-related illnesses. Such a broader scope allowed the inclusion of transmissible diseases among the causes for concern in working settings. COVID-19 has had a profound impact globally, resulting in millions of infections, often lethal. From its appearance, COVID-19 was found to affect specific groups of workers at higher risk of contracting the virus due to their occupation or workplace conditions, which accounts for its consideration as a potential work-related disease. This overview examines various aspects of COVID-19 based on articles published in our journal. Specifically, the epidemiology of COVID-19 is discussed, including mortality rates and groups at higher risk. The diagnosis, measures to prevent contagion, vaccination efforts, long-term effects, and psychosocial factors are also summarized. The emerging picture is that COVID-19 has been a trigger accelerating the change of paradigm of occupational medicine, which is more and more concerned with prevention.

Ergonomics of bronchoscopy: good advice or a pain in the neck?

Interventional pulmonologists require a unique set of skills including precise motor abilities and physical endurance, but surprisingly the application of ergonomic principles in the field of bronchoscopy remains limited. This is particularly intriguing when considering the significant impact that poor ergonomics can have on diagnostic aptitude, income potential and overall health. It is therefore imperative to provide comprehensive education to physicians regarding the significance of ergonomics in their work, especially considering the introduction of advanced diagnostic and therapeutic procedures. By implementing simple yet effective measures (e.g. maintaining neutral positions of the wrist, neck and shoulder; adjusting the height of tables and monitors; incorporating scheduled breaks; and engaging in regular exercises), the risk of injuries can be substantially reduced. Moreover, objective tools are readily available to assess ergonomic postures and estimate the likelihood of work-related musculoskeletal injuries. This review aims to evaluate the current literature on the impact of procedure-related musculoskeletal pain on practising pulmonologists and identify modifiable factors for future research.

A current affair: worker perceptions of noise exposure and occupational hearing loss in Australian coal mines.

BACKGROUND: The objective of the online survey was to determine worker attitudes towards, perceptions on hearing loss, and management of workplace noise; and to identify barriers within current strategies that prevent effective management of hearing health in Australian mines. DESIGN: This cross-sectional study utilized a modified survey design, initially designed for use by Safe Work Australia for a broader study published in 2010. STUDY SAMPLE: The survey questionnaire was made available online to volunteer participants, recruited with the assistance of State and National Health and Safety, and mining organizations. Volunteer participants were required to be proficient in English, be employed by an Australian underground or open cut mine, including coal processing plants; or work as a contractor on one of the specified mine sites. All mining employees, regardless of occupation, job title, and occupational hearing loss classification or status, were invited to complete the questionnaire. RESULTS: Almost 60% of respondents indicated that they had high noise exposure for than 10 yr or more, and have some trouble hearing, mostly associated with infrequent tinnitus. Nearly 71% of these workers believe that the noise control strategies in their workplaces are effective, but this mostly refers to the use of hearing protection devices. CONCLUSION: The results indicate that general knowledge on the cause and effect of noise exposure in the workplace is well understood. However, due to the long latency associated with the development of noise-induced hearing loss (NIHL), there is an issue urgency in terms of risk management. It is surprising that most of the respondents recommended more inspections and administrative controls, especially since most respondents were health, safety, and environment (HSE) professionals. HSE professionals should be advocating for higher order, more permanent solutions, and not purely administrative controls and personal protective equipment. These findings raise the question of whether there is a multifaceted working-culture issue that needs to be addressed, in combination with higher order control implementation.

Trends in Occupational Diseases in Italian Industry and Services From 2006 To 2019.

BACKGROUND: There is a paucity of data on occupational disease incidence in Italy, and we analyzed the trend on time as an incidence rate ratio (IRR). METHODS: Occupational diseases reported to the Italian National Insurance for Occupational Diseases (INAIL) in industrial and services sectors from 2006 to 2019 were considered and analyzed. Annual case counts were analyzed using a Poisson regression model to estimate incidence trends. RESULTS: The incidence of occupational diseases in the industrial and services sectors in 2019 was 261 cases for 100,000 workers, with musculoskeletal disorders (MSDs) representing 65% of the total cases, their incidence being 169.5 cases per 100,000 workers. The incidence of ear diseases (ED) decreased to 20.8 cases for 100,000 workers. The annual change in incidence (IRR) was 1.08 (CI 95% 1.07-1.11) for MSDs, 1.08 (CI 95% 1.06-1.10) for cancers, and 1.04 (CI 95% 1.03-1.06) for respiratory diseases. The trend was significantly negative for ear diseases, 0.96 (CI 95% 0.96-0.97), and skin diseases 0.93 (CI 95% 0.92-0.93). No changes were found for asbestos and mental diseases. CONCLUSIONS: During the study period, occupational diseases increased in Italy, mainly for MSDs, due to a changeover in eligibility criteria from 2008. However, the overall incidence was lower than in other EU Countries. More efforts are needed to harmonize the legislation for joint action in the prevention and recognition of occupational diseases.

Indian surgery Trainee's perspective on surgical ergonomics principles and education: A long road ahead.

INTRODUCTION: This study aimed to determine the baseline knowledge and beliefs, along with the impact of incorporating surgical ergonomics lectures during a residency. METHODS: A cohort of 123 Indian surgical residents participated in this educational intervention, which consisted of two educational webinars on ergonomics. Both pre- and post-intervention surveys were electronically sent to the participants. These included questions related to their demographics, prevalence of musculoskeletal (MSK) symptoms, and factors affecting participant awareness of ergonomic recommendations. RESULTS: Seventy-one residents responded to the pre-webinar survey. Eighty-five percent of respondents reported MSK symptoms, with the most common being pain (70%) and stiffness (40%), which the residents attributed to their surgical training. Forty-six residents completed the post-webinar survey. The majority of respondents strongly agreed or agreed that surgical ergonomic educational sessions improved their understanding of the fundamental causes of MSK symptoms and increased their awareness of options available for prevention MSK injuries. CONCLUSION: The rate of MSK symptoms and/or injury was high among this cohort of surgical residents. These surveys and educational session demonstrated there is limited awareness of the comprehension of ergonomics related to surgical procedures. Our study shows that a simple surgical ergonomic educational intervention can lead to improved understanding of prevention and ergonomic changes.

Work-related musculoskeletal pain and discomfort in laparoscopic surgeons: an international multispecialty survey.

INTRODUCTION: As laparoscopic surgery is used more widely across the globe and within multiple surgical specialties the potential impact on surgeons is yet to be fully quantified. Maintenance of uncomfortable body positions may lead to work-related musculoskeletal disorders (WMSD) in surgeons, with potential knock-on effects. METHODS: An international open online survey of multispecialty laparoscopic surgeons was carried out, designed and reported in accordance with the CHERRIES checklist for internet e-survey research. There was no paid advertising and no incentives offered. RESULTS: A total of 259 surgeons from 9 specialties and 32 countries answered the survey, with 90% reporting pain attributable to performing laparoscopic surgery. All training grades were represented. Longer average operative duration and a greater number of years in practice were both associated with a significantly higher prevalence of pain. Surgeons with a pre-existing injury were significantly more likely to report pain than those without. Twenty per cent of surgeons would consider early retirement owing to pain. CONCLUSIONS: The impact on surgeons of performing laparoscopic surgery is significant, even given the limitations of an open survey. Innovations such as robotic surgery and improved ergonomic education may reduce the incidence of WMSD in surgeons, to mitigate both the personal effects on surgeons and the wider effect on the future surgical workforce.

Acute myocardial infarctions identified in the Manitoba Occupational Disease Surveillance System: A linkage of worker's compensation and provincial health data.

INTRODUCTION: The purpose of this study was to identify jobs and industries that may be associated with increased or decreased risk of myocardial infarction. METHODS: We linked provincial health care data with Workers Compensation Board (WCB) of Manitoba claims data to create the Manitoba Occupational Disease Surveillance System (MODSS). Workers were eligible for inclusion in this study if their WCB claim listed an occupation, their claim could be linked to health data, they had an accepted non-acute myocardial infarction (AMI) compensation time loss claim and were free of a recent (<1 year) AMI diagnosis at the start of disease follow-up. AMI cases were identified as the most-responsible diagnosis in the hospitalization file (ICD-9 410 or ICD-10 I20). Cases were included if they occurred after the WCB record injury date until end of coverage, either through moving out of province, reaching age 65, death, or the end of the study period (March 1, 2020). RESULTS: We identified 1880 incident AMIs amongst 150,022 claims recorded in the MODSS (1.25%). A number of industries and occupations were found to have higher and lower AMI rates. Care providers and educational, legal, and public protection support occupations had a lower hazard ratio (HR; 0.64; 95% confidence interval [CI]: 0.44-0.92) compared to the overall cohort. Female chefs and cooks, and male butchers and bakers had elevated AMI HRs. Both male and female transport and heavy equipment operators and related maintenance occupations had increased HRs (1.48; 95% CI: 1.30-1.67). Often male and female workers employed in the same occupations had congruent AMI risks, but this was not always the case. CONCLUSIONS: The linkage of a WCB data set with provincial health claims data led to the identification of a number of occupations with elevated risks of AMI in Manitoba. This was most notable in the transportation industry. Identifying work areas with increased risk of AMIs could lead to targeted educational efforts and potential workplace modifications to lower this risk.

[Analysis of the status of occupational disease prevention and control of enterprises in mining and manufacturing industries in China in 2019].

Objective: To analyze the status of prevention and treatment of occupational diseases among mining and manufacturing industries in China in 2019, provide the scientific basis for the formulation and revision of policies and standards of prevention and treatment of occupational diseases. Methods: In May 2022, Collecting data of a project named Surveillance of Occupational Hazards in the Workplace in 2019 through the National Surveillance System for Occupational Hazards in the workplace. Compare the status of prevention and treatment of occupational diseases in 63 563 enterprises of mining and manufacturing industries among different dimensions. Results: The training rate of managers was 76.17% and that of occupational health managers was 76.97%. The rate of reporting of occupational diseases hazardous items was 67.58%, the rate of launching of the detection of occupational hazards was 57.16%, and the rate of launching of occupational health examination was 62.42%. Excluding the distribution rate of dust mask, the installation rate of various occupational prevention facilities and the distribution rate of gas mask and hearing protector were less than 80%. The differences in all the indicators among different areas, enterprise scales, economic types were statistically significant (P<0.05) . Conclusion: There are still some enterprises which are relatively weak in the ability of the prevention and treatment of occupational diseases in China. Measures such as special support, guidance and strengthen supervision should be taken towards those enterprises toimprove the awareness of prevention and treatment of occupational diseases and the level of that.

A narrative review of ergonomic problems, principles, and potential solutions in surgical operations.

BACKGROUND: Ergonomic development and awareness are critical to the long-term health and well-being of surgeons. Work-related musculoskeletal disorders affect an overwhelming majority of surgeons, and various operative modalities (open, laparoscopic, and robotic surgery) differentially affect the musculoskeletal system. Previous reviews have addressed various aspects of surgical ergonomic history or methods of ergonomic assessment, but the purpose of this study is to synthesize ergonomic analysis by surgical modality while discussing future directions of the field based on current perioperative interventions. METHODS: pubmed was queried for "ergonomics," "work-related musculoskeletal disorders," and "surgery," which returned 124 results. From the 122 English-language papers, a further search was conducted via the articles' sources for relevant literature. RESULTS: Ninety-nine sources were ultimately included. Work-related musculoskeletal disorders culminate in detrimental effects ranging from chronic pain and paresthesias to reduced operative time and consideration for early retirement. Underreporting symptoms and a lack of awareness of proper ergonomic principles substantially hinder the widespread utilization of ergonomic techniques in the operating room, reducing the quality of life and career longevity. Therapeutic interventions exist at some institutions but require further research and development for necessary widespread implementation. CONCLUSION: Awareness of proper ergonomic principles and the detrimental effects of musculoskeletal disorders is the first step in protecting against this universal problem. Implementing ergonomic practices in the operating room is at a crossroads, and incorporating these principles into everyday life must be a priority for all surgeons.

Female Surgical Ergonomics in Otolaryngology: A Qualitative Study.

OBJECTIVE: To explore the surgical ergonomic challenges experienced by women in otolaryngology, identify specific equipment that is ergonomically challenging, and assess the impact of suboptimal ergonomics on female otolaryngologists. METHODS: We performed a qualitative study using an interpretive framework rooted in grounded theory. We performed semi-structured qualitative interviews of 14 female otolaryngologists from nine institutions at various stages in training and across subspecialties. Interviews were independently analyzed by thematic content analysis by two researchers and inter-rater reliability was assessed via Cohen's kappa. Differing opinions were reconciled via discussion. RESULTS: Participants noted difficulties with equipment including microscopes, chairs, step stools, and tables as well as difficulty using larger surgical instruments, preference for smaller instruments, frustration with lack of smaller instruments, and a desire for a larger spectrum of instrument sizes. Participants reported neck, hand, and back pain associated with operating. Participants suggested modifications to the operative environment, including a wider variety of instrument sizes, adjustable instruments, and more focus and attention on ergonomic issues and the range of surgeon physiques. Participants felt that optimizing their operating room set-up was an additional burden on them, and that lack of inclusive instrumentation affected their sense of belonging. Participants emphasized positive stories of mentorship and empowerment from peers and superiors of all genders. CONCLUSION: Female otolaryngologists face unique ergonomic challenges. As the otolaryngology workforce becomes increasingly diverse, it is important to address the needs of a diverse set of physiques to avoid inadvertently disadvantaging certain individuals. LEVEL OF EVIDENCE: N/A Laryngoscope, 133:3034-3041, 2023.

Musculoskeletal injuries in cross-speciality surgeons: a survey of UK-based doctors.

Musculoskeletal disorder (MSD) rates amongst surgeons are as high as 80% and injuries within the healthcare setting are an impending epidemic with a distinct lack of intervention to prevent it. The career-shortening impact this has on the cohort of highly trained workers within the National Health Service must be highlighted. This study was designed to be the first UK-based cross-speciality survey to establish the prevalence and impact of MSDs. A quantitative survey from the standardised Nordic Questionnaire was distributed compromising questions assessing the prevalence of musculoskeletal complaints in all anatomical zones. 86.5% of the surgeons reported musculoskeletal discomfort over the last 12 months, with 92% of respondents detailing issues over the last 5 years. 63% state this had an impact on their home life, with a further 86% believing their symptoms are related to posture at work. 37.5% of surgeons admitted to altering or stopping work due to MSDs. This survey demonstrates high rates of MSK injuries in surgeons with a certain subsequent impact on occupational safety and career length. Robotic surgery may be a solution to the impending problem however further research is needed with policies developed to protect our health workers.

[Occupational obstructive airway diseases: How can early diagnosis be made to avoid chronic courses?] / Obstruktive Atemwegserkrankungen im Beruf: Wie gelingt eine frühe Diagnostik zur Vermeidung chronischer Verläufe?

Since abolishing the obligation to terminate the harmful professional activity from January 1st, 2021 onwards for some occupational diseases including obstructive respiratory diseases in Germany, the recognition of occupational diseases coded under 4301, 4302 and 1315 according the Occupational Diseases Ordinance has increased significantly. By the time these diseasese are recognized, they are usually already at an advanced stage. Therefore, early detection will play a greater role in the future, as the statutory accident insurance can offer individual preventive measures in order to minimize the consequences of illness and thus also the socio-economic burden. However, precursors of such obstructive airway diseases are often overlooked. For optimizing early detection, the statutory accident insurance worked out an early notification procedure for the respiratory tract - comparable to the already well-established dermatological procedure. "Early cases" from the pilot regions can be reported there; to qualify for being reported as early cases, patients must persue insured professional activity with potential effects on the respiratory tract and suffer from a disease of the upper or lower respiratory tract according to the ICD-10 code (e.g. J31.0 chronic rhinitis).

Association of Vibrotactile Biofeedback With Reduced Ergonomic Risk for Surgeons During Tonsillectomy.

Importance: Work-related musculoskeletal disorders are common among otolaryngologists and can be associated with decreased productivity, missed workdays, and reduced quality of life. Ergonomic risk for surgeons is elevated during common otolaryngology procedures; current ergonomic interventions lack the ability to provide real-time feedback. The ability to quantify and mitigate ergonomic risk during surgery may reduce work-related musculoskeletal disorders. Objective: To quantify the association of vibrotactile biofeedback with intraoperative ergonomic risk to surgeons during tonsillectomy. Design, Setting, and Participants: This cross-sectional study was conducted between June 2021 and October 2021 at a freestanding tertiary care children's hospital and included 11 attending pediatric otolaryngologists. Data analysis was conducted from August to October 2021. Interventions: Real-time quantification of ergonomic risk during tonsillectomy and the use of a vibrotactile biofeedback posture monitor. Main Outcomes and Measures: Association of vibrotactile biofeedback with objective measures of ergonomic risk. Assessment tools included the Rapid Upper Limb Assessment, craniovertebral angle, and time spent in an at-risk posture. Results: Eleven surgeons (mean [SD] age 42 [7] years; 2 women [18%]) performed 126 procedures with continuous posture monitoring in the presence (80 [63%]) and absence (46 [37%]) of vibrotactile biofeedback. No complications or delays associated with the device were reported. Intraoperative vibrotactile biofeedback was associated with improved Rapid Upper Limit Assessment neck, trunk, and leg scores by 0.15 (95% CI, 0.05-0.25), improved craniovertebral angle by 1.9 (95% CI, 0.32-3.40), and decreased overall time spent in an at-risk posture by 30% (95% CI, 22%-39%). Conclusions and Relevance: The results of this cross-sectional study suggest that use of a vibrotactile biofeedback device to quantify and mitigate ergonomic risk for surgeons is feasible and safe while performing surgery. Vibrotactile biofeedback was associated with reduced ergonomic risk during tonsillectomy and may have a role in improving surgical ergonomics and preventing work-related musculoskeletal disorders.

Preventing work-related musculoskeletal injuries among oral and maxillofacial surgeons.

BACKGROUND: Oral and maxillofacial surgeons (OMS) are continually required to adjust position and posture to access the limited surgical field in and around the head and neck, oral cavity, and oropharynx. Very limited data exists that quantifies the burden of musculoskeletal disorders (MSD) among OMS. OBJECTIVE: This exploratory study seeks to address these literature gaps by assessing the prevalence of MSD among OMS. METHOD: A 12-question survey was designed to investigate the prevalence of MSD for OMS, including residents in training, actively practicing surgeons, and retired surgeons. Seventy-six surveys were distributed and completed in person by surgeons attending professional conferences from September 2018-September 2019. Survey questions included the Baker-Wong Faces pain scale, years in practice, number of hours worked per week, job tenure, pain attributable to work, and age. The Nordic scale identified and delineated anatomic site of musculoskeletal complaints, duration and treatment sought. RESULTS: The most frequently cited sources and locations of pain attributable to occupation were shoulders, neck, and lower back. The risk of MSD symptoms was relatively two-fold [PR = 2.54, 95% CI = 0.90, 7.22] among OMS in practice for more than ten years compared to those in practice less than ten years. After adjusting for age and hours worked per week as potential confounders, the risk of MSD symptoms was higher among OMS in practice for more than ten years compared to those with less than ten years of experience, despite no statistically significant association. CONCLUSION: OMS are impacted by a high prevalence of MSD. The neck, shoulder, and lower back are the most frequently affected with discomfort and pain. This study found that practicing oral and maxillofacial surgery for more than 10 years is a potential risk factor for experiencing MSD.
