Ergonomics in the Operating Room: The Cervicospinal Health of Today’s Surgeons

Exoscope-assisted orbital fracture reduction surgery-Clinical assessment by surgeons: A retrospective cohort study

BACKGROUND

Exoscope-assisted digital imaging allows continuous real-time visualization of the surgical site on a large 3D monitor. We evaluated its usefulness in orbital fracture reduction surgery, a procedure with a narrow and deep operative field that restricts direct visibility for the operating surgeon.

METHODS

This retrospective cohort study included all patients who underwent orbital floor fracture reduction with an absorbable plate via a subciliary approach at our institution from January 2022 to December 2024. ORBEYE 3D exoscope system (Olympus, Tokyo, Japan) was used in all cases when available, as the device was shared among several departments in our institution. Surgeries performed with and without the ORBEYE exoscope were compared for the following preoperative variables: (i) years since the surgeon's graduation and (ii) days from injury to surgery, and outcome variables including (iii) operative time, (iv) blood loss, and (v) absorbable plate size. Surgeons also completed a questionnaire regarding their experience with ORBEYE.

RESULTS

Eleven patients underwent conventional surgery, and 10 underwent ORBEYE-assisted surgery. ORBEYE-assisted surgery resulted in a significantly shorter operative time, while no significant differences were observed in other preoperative or outcome variables. The involved surgeons reported reduced physical strain, particularly in the neck, as well as improved collaboration and education. Despite some disadvantages, all surgeons expressed a positive attitude toward continued ORBEYE use.

CONCLUSIONS

ORBEYE-assisted surgery offers significant advantages in orbital floor fracture reduction, including reduced operative time, improved ergonomics, and enhanced teamwork and education. Its drawbacks are relatively minor, and broader adoption in plastic surgery should be considered.

Upper Eyelid Blepharoptosis Correction Performed Under the Operating Microscope

BACKGROUND

Eyelid blepharoptosis correction is commonly performed with loupe magnification. The posture in which this operation is performed, with cervical spine flexion and forward lean, places significant stress on the cervical spine.

OBJECTIVES

Performing upper eyelid surgery under the operating microscope is not commonly practiced. The benefits are significantly better surgeon's posture while operating and potential improved surgical outcomes. These ergonomic and outcome measures were examined in this prospective study.

METHODS

From the June 2023 to June 2024, 86 cases of bilateral ptosis correction were performed (172 eyelids) with the microscope.

RESULTS

The mean duration of surgery was 115 minutes for bilateral ptosis correction. Our revision rate was 3%. We found the following surgical advantages with this approach: (1) Superior visual clarity with a higher and adjustable magnification and (2) consistent confocal illumination of the operative field, (3) improved precision of dissection, (4) hemostasis and (5) clear distinction of fine anatomical structures crucial to reconstructive success. The postoperative recovery was faster with better functional and cosmetic outcomes as bruising and edema was minimized from less induction of surgical trauma. Importantly as well, for the surgeon, the operating microscope may extend the longevity of one's surgical career. The postural ergonomics and cervical unloading afforded by the operating microscope can mitigate cervical spine stress and injury CONCLUSIONS: We found 2 compelling benefits with this approach. Firstly, the surgical outcomes were superior. Secondly, the surgeon's posture is upright while operating. This long-term benefits of this could not be overstated in preventing cervical spine injuries.

Cervical spine positioning patterns amongst hand surgeons: A critical analysis of surgical posture

Aim

This study aims to assess the cervical spine positioning of consultant and trainee hand surgeons during standardised hand surgeries, focusing on the prevalence of sustained end-range postures, particularly cervical spine flexion.

Background

Surgeons often perform procedures that require maintenance of sustained postures for prolonged periods of time. Hand surgeons may be at increased risk of sustained end of range postures, particularly cervical spine flexion. This can lead to strain on the musculoskeletal structures of the neck. Recent evidence suggests a higher incidence of neck dysfunction in hand surgeons, leading to an associated morbidity.

Methods

We examined hand surgeons of all experience levels during 40 common hand surgery procedures. We used real-time dynamic goniometric measurements of neck flexion using the "UPRIGHT GO 2" device and accompanying smartphone app. Neck flexion exceeding 40° was used as the threshold for defining an acceptable neck position.

Results

Analysis included 20 total subjects at various levels of medical training (SHO n ​= ​6, Registrar n ​= ​9, Consultant n ​= ​5) performing surgeries under different conditions. Maladaptive neck positions were prevalent, with junior surgeons exhibiting such postures for 71 ​% of procedure time compared to 60 ​% for consultants. This underscores the potential contribution of sustained end-range postures to cervical spine dysfunction in hand surgeons, highlighting an early intervention opportunity. Notably, participants reported varied experiences with neck pain and expressed unanimous interest in integrating biofeedback posture devices into surgical training, with a single consultant expressing reservations.

Understanding the Impact of Ergonomic Practices on Musculoskeletal-Related Symptoms and Emotional Wellness in Craniofacial Surgeons

BACKGROUND

A systematic review conducted in 2017 found that Musculoskeletal (MSK) injuries were prevalent among surgeons. Few studies have assessed the role that poor surgical ergonomic practices have had in the development of MSK injuries in plastic and reconstructive surgery (PRS), and fewer specifically in craniofacial surgeons. The impact that MSK injuries have on the emotional well-being of craniofacial surgeons is also not well understood.

METHODS

A branched logic survey with a maximum of 35 questions pertaining to surgical practices, MSK injuries, and emotional well-being was distributed to all active attending physicians who were members of the American Society of Maxillofacial Surgeons (ASMS). The responses were divided into 2 groups, surgeons who reported developing MSK injuries or physical discomfort and those who denied developing MSK injuries or physical discomfort. Data analysis was performed to determine which factors contributed to the incidence of MSK injury and the emotional impact that these injuries had on craniofacial surgeons.

RESULTS

A total of 82 active craniofacial surgeons completed responses to the survey for an overall response rate of 16.6%. Of these respondents, 65.9% (n=54) suffered MSK injuries or physical discomfort, and 53.7% (29/54) reported difficulty with either falling asleep or staying asleep because of these symptoms within the last year. Both male and female respondents reported experiencing some level of anxiety or depression because of their MSK injuries.

CONCLUSION

The impact of a MSK injury may impact both physical and emotional wellness of craniofacial surgeons. This study found that a high percentage of craniofacial surgeons have MSK-injuries whereas some have reported a negative impact on their sleep and emotional well-being.

Neurosurgical applications of the exoscope: from in vitro studies to real-life surgical use in selective dorsal rhizotomy

BACKGROUND

The microscope has been the gold standard in neurosurgical practice due to its ability to magnify anatomical structures. However, it has limitations, including restricted visual fields and ergonomic challenges that can lead to surgeon fatigue and musculoskeletal issues. The exoscope is an emerging technology that may address these limitations by offering comparable magnification with improved ergonomics.

METHODS

This study compares the traditional microscope (KINEVO 900) with a 3D digital exoscope (Aeos Digital Microscope) in visual field width, image sharpness, and ergonomic impact. Visual field assessments were conducted using millimeter paper at a fixed distance, while image sharpness was evaluated using graph paper with pins at different depths. Ergonomic evaluation involved simulating surgical positions using a spine anatomical model. The practical applicability was tested during Selective Dorsal Rhizotomy (SDR) procedures, comparing the surgeon's experience with both devices over 20 consecutive cases.

RESULTS

The exoscope provided a larger visual field (81.18 cm2) compared to the microscope's (54.10 cm2). Image sharpness was similar for both devices across various depths and zoom levels. Ergonomically, the exoscope allowed the surgeon to maintain a neutral posture while visualizing extreme angles, unlike the microscope, which required significant upper body movement. In SDR procedures, the exoscope improved surgeon comfort and interaction with the operating team, despite an initial learning curve.

CONCLUSIONS

The exoscope presents notable advantages in terms of visual field and ergonomics. The exoscope's ability to facilitate better posture and team communication without compromising image quality makes it an addition to neurosurgical practice, as in SDR.

Ergonomic practices and interventions in plastic and reconstructive surgery: A systematic review

INTRODUCTION

Ergonomics have significant implications for the surgical workforce that performs at the interface between human-operated equipment and patient anatomy to achieve clinical results. This systematic review evaluated the literature discussing ergonomics in plastic surgery to explore current knowledge, evaluate trends, and identify prime gaps for future study.

METHODS

A systematic search strategy was developed by a licensed librarian and plastic surgeon to query all manuscripts evaluating ergonomics in plastic and reconstructive surgery. Two independent reviewers screened abstracts, evaluated full texts, and extracted data.

RESULTS

Forty-six studies were ultimately included. The number of published studies increased significantly over time when evaluated by year (ρ = 0.660, p < 0.001), with 17 (36.9%) written since 2020. Studies more commonly discussed musculoskeletal pain/disorders (n = 23) compared to surgical instrumentation or technology (n = 18, p = 0.390), operative posture (n = 14, p = 0.041), surgical technique (n = 6, p = 0.002), peri-surgical practices (n = 5, p < 0.001), and surgeon physiology (n = 3, p < 0.001). Among the 19 studies, including interventions, approaches more frequently involved novel instrumentation or technology (n = 14, 73.4%) compared to peri-surgical practices (n = 3, 6.5%, p < 0.001) or operative posture (n = 2, 4.3%, p < 0.001).

CONCLUSIONS

Ergonomics in plastic surgery has gained significant interest over time, with recent years representing a large proportion of published literature. Although most studies discuss musculoskeletal pain, the proportion of studies addressing posture and surgical practices are comparatively underrepresented, suggesting an opportunity for future intervention.

Ergonomics in the operating room and surgical training: a survey on the Italian scenario

Introduction

Surgical-related injuries are frequent, in fact the reported percentage of musculoskeletal disorders in surgeons is between 47% and 87%. These conditions are caused by long periods of standing, incorrect postures, repeated movements, little rest between operations, the lack of integrated operator rooms, the correct number and arrangement of monitors and the use of non-ergonomic instruments. This survey aims to assess the Italian overview both highlighting how prevalent surgical-related injury is in our surgeons and whether there is an operating room ergonomics education program in Italian surgical specialty schools.

Methods

An anonymous questionnaire was designed through SurveyMonkey© web application. This survey was composed of 3 different sections concerning the general characteristics of the participants, their surgical background and any training performed, and any injuries or ailments related to the surgical activity. The survey was carried out in the period 1th of December 2022 and the 6th of February 2023.

Results

At the close of our survey, 300 responses were collected. Among the participants, the two most represented specialties were Gynecology and Obstetrics (42.3%) and General Surgery (39.7%) and surgeons were mainly employed in the Northern regions of Italy (54.8%). Analyzing the participants' background, 61.7% of the respondents had laparoscopic training during their training and only 53.1% had a pelvic trainer during their residency. In accordance with 98.7% of the respondents, during surgery we have the feeling of being in an uncomfortable position that causes discomfort or muscle pain, and regarding the frequency of these discomforts, the majority of our study population experiences these problems monthly (46.2%), while in 29.6% it is experienced weekly, 12.1% annually and finally 12.1% daily. The surgical approach that is most correlated with these disorders is laparoscopy (62.7%) while the one that causes the least discomfort is robotic surgery (1.4%). These discomforts cause 43.9% of our population to take a break or do short exercises to reduce pain during surgery, and the body areas most affected are the back (61.6%), neck (40.6%) and shoulders (37.8%).

Conclusion

Despite this, our survey allows us to highlight some now-known gaps present in the surgical training program of our schools and the lack of protection toward our surgeons during their long career.

Ergonomics in facial plastic and reconstructive surgery

PURPOSE OF REVIEW

Understanding effective ergonomic interventions is crucial for enhancing occupational health and career longevity. There is a paucity of clear ergonomics guidelines in facial plastic and reconstructive surgery (FPRS), placing practitioners at high risk of work-related musculoskeletal disorders (WMSDs) and their consequences.

RECENT FINDINGS

There is mounting evidence that FPRS specialists are at increased risk of WMSDs as compared with the public and other surgical specialties. Numerous studies have demonstrated that implementation of ergonomics principles in surgery decreases WMSDs. Furthermore, WMSDs are reported as early as the first year of surgical residency, marking the importance of early intervention.

SUMMARY

Fatigue and physical injuries among surgeons occur more often than expected, particularly during complex, extended procedures that necessitate maintaining a constant posture. FPRS procedure often place surgeons into procrustean positions. Thus, integrating ergonomic practices into the practice of FPRS is essential for reducing WMSDs.

A systematic review of morphine equivalent conversions in plastic surgery: Current methods and future directions

INTRODUCTION

Protocols surrounding opioid reduction have become commonplace in plastic surgery to improve peri-operative outcomes. Within such protocols, opioid requirement is a frequently analyzed outcome. Though often examined, there is no literature standard conversion for morphine milligram equivalents (MME) at present, leading to questionable external validity. We hypothesized significant heterogeneity in MME reporting would exist within plastic surgery literature.

METHODS

Following the PRISMA guidelines, the authors conducted a systematic review of 16 journals. Clinical studies focused on opioid reduction within plastic surgery were identified. Primary outcomes included reporting of morphine equivalents (ME) delivery (IV/oral), operative ME, inpatient ME, outpatient ME, timeline, and method of calculation.

RESULTS

Among the 101 studies analyzed, 73% reported opioid requirements in the form of ME. Among those that used ME, 3% reported IV ME, 41% reported oral, 32% reported both, and 25% gave no indication of either. Operative ME were reported in 19% of studies. Furthermore, 54% of studies reported inpatient ME whereas 32% of studies reported outpatient ME. Only 19% reported the number of days opioids were consumed postoperatively. Moreover, 27% of the studies reported the actual method of ME conversion, with 17 unique methods described. Only 8 studies (8%) reported using the Center for Disease Control and Prevention guidelines for ME conversion.

CONCLUSION

There is significant variability among the reported ME conversion methodology within plastic surgery literature. Highlighting these discrepancies is an essential step in creating and implementing a single, standard method to mitigate opioid morbidity in plastic surgery and to optimize enhanced recovery protocols.

Utility of a Neuromuscular Activation Exercise Protocol on Surgeon Posture

BACKGROUND

Surgeons are at risk for musculoskeletal disorders from ergonomic strain in the operating room. These deficits may stem from neuromuscular control deficits. Neuromuscular activation exercises (NMEs) may strengthen the brain-muscle connection. This study aimed to assess the utility of a surgeon-oriented NME protocol on posture.

METHODS

Surgeons, operating room staff, and medical students completed a professionally established NME routine. An electronic application, PostureScreen®, assessed participants' posture. A long-term cohort was assessed before and after a 2 to 6-week routine. A short-term cohort was assessed immediately before and after completion. All participants additionally completed a postintervention survey.

RESULTS

After intervention, the short-term cohort (n = 47) had significantly reduced frontal and sagittal postural deviation (P < 0.05). A significant decrease in effective head weight was additionally demonstrated with decreased neck flexion and increased cerebral-cervical symmetry (P < 0.05).The long-term cohort (n = 6) showed a significant postintervention decrease in lateral and anterior shoulder translation (P < 0.05). Total anterior translational deviations demonstrated trend-level decrease (P = 0.078). This demonstrates that after intervention, participants' shoulders were more centered with the spine as opposed to shifted right or left. Survey results showed participants favored exercises that immediately brought relief of tension.

CONCLUSIONS

A decrease in postural deviations associated with NME in both cohorts demonstrates NME as a potential mechanism to protect surgeon musculoskeletal health and improve well-being. Survey results demonstrate areas of refinement for NME protocol design.

Biomechanical and ergonomic risks associated with cervical musculoskeletal dysfunction amongst surgeons: A systematic review

INTRODUCTION

Surgeons are at high risk of developing musculoskeletal symptoms due to a range of factors including, maladaptive positioning and surgical ergonomics. Cervical muscle strain and biomechanical load is most prevalent due to repetitive motions and prolonged static neck positioning. This issue is apparent through reports of prevalence between 10 and 74.4% among surgeons. The aim of this systematic review is to provide an objective assessment of the clinical evidence available and a descriptive analysis of the effects of kinematics and surgical ergonomics on the prevalence of surgeons' cervical musculoskeletal pain.

METHODS

This is PRISMA-compliant systematic review of clinical studies assessing the prevalence of cervical musculoskeletal dysfunction in surgeons by searching PUBMED and Ovid EMBASE databases from inception to 19th October 2023. Study quality was graded according to the National Institutes of Health study quality assessment tools.

RESULTS

A total of 9 studies were included in the final qualitative analysis. The use of loupes, open surgery and excessive neck flexion (>30°) were associated with cervical dysfunction. Comparison of study outcomes was challenging due to heterogeneity within study methods and the paucity of methodological quality.

CONCLUSION

The current literature assessing ergonomic and biomechanical factors predisposing surgeons to cervical musculoskeletal dysfunction is insufficient to provide reliable guidance for clinicians. Although the literature identifies factors contributing to work-related cervical dysfunction, few attempt to evaluate interventions for improved surgical ergonomics. An objective assessment of interventions that prompt postural correction with the aim to improve neck pain in surgeon cohorts is warranted.

Ergonomic benefit using heads-up display compared to conventional surgical microscope in Japanese ophthalmologists

PURPOSE

Occupational musculoskeletal disorders are prevalent in ophthalmic surgeons and can impact surgeons' well-being and productivity. Heads-up displays may reduce ergonomic stress compared to conventional microscopes. This cross-sectional, non-interventional study compared ergonomic experience between heads-up display and conventional ocular microscopes.

METHODS

The study protocol was approved by the independent ethics committee and nonprofit organization MINS Institutional Review Board. An online questionnaire was distributed to a sample of ophthalmic surgeons in Japan with experience operating with heads-up display. The questionnaire captured surgeon-specific variables, the standardized Nordic Musculoskeletal Questionnaire, and custom questions to compare heads-up display and conventional microscope and understand long-term impacts of musculoskeletal disorders.

RESULTS

Analysis was conducted on responses from 67 surgeons with a mean 25 years of practice and 2.7 years using heads-up display. Many surgeons agreed or strongly agreed that heads-up display reduced the severity (40%) and frequency (40%) of pain and discomfort, improved posture (61%), and improved overall comfort (61%). Of respondents who experienced asthenopia (n = 59) or pain/discomfort during operation (n = 61), 54% reported improvement in asthenopia and 72% reported feeling less pain/discomfort since using heads-up display. Overall, 69% reported preference for heads-up display.

CONCLUSION

This study provides novel data on musculoskeletal disorders and the long-term impacts of ergonomic strain reported by ophthalmologists building on existing literature demonstrating ergonomic and other advantages of heads-up display. Future studies with objective ergonomic assessment are warranted to validate these findings.

Ergonomics in Craniofacial Surgery: Can We Do Better? A Quality Improvement Study

OBJECTIVE

Many plastic surgeons experience musculoskeletal strain and injury from poor ergonomics during surgery. This is associated with reduced performance, shortened careers, and decreased quality of life. This study compared the ergonomics of the conventional operating table headrest and the Mayfield headrest in craniofacial surgery.

METHODS

A prospective cohort study of patients undergoing craniofacial operations between November 20, 2022 and April 26, 2023, within a single craniofacial surgeon's practice. The authors obtained data on the total duration of the operation and Rapid Entire Body Assessment (REBA) scores for the primary surgeon and assistant.

RESULTS

Four operations (mean: 147 ± 60.9 min) were included in the regular headrest group, and 8 in the Mayfield headrest group (mean: 61±53.4 min). Four hundred fifty-five regular headrest time points and 851 Mayfield time points were recorded. Eight hundred thirty-five regular headrest time points and 538 Mayfield time points were recorded. The mean REBA score for the regular headrest was 5.79 ± 1.9, which was higher than the Mayfield (5.01 ± 2.0; P < 0.0001). Subgroup analysis showed the mean REBA score for the primary surgeon (5.89 ± 2.0) was higher than the assist (5.48 ± 1.6) in the regular headrest group ( P < 0.0001), whereas the converse was true for the Mayfield headrest (primary surgeon: 4.67 ± 1.8, assist: 5.65 ± 2.15, P < 0.0001).

CONCLUSIONS

Ergonomic scores were better using the Mayfield headrest than the regular headrest. The primary surgeon scored better with the Mayfield headrest, whereas the assists had better scores with the regular headrest.

Factors Affecting Perioperative Nurse Adherence to Ergonomic Safety Measures

AORN has identified safety risks unique to the perioperative setting and has developed ergonomic safety measures to help prevent musculoskeletal injuries and disorders. Little is known about adherence to these safety measures or the perceived barriers and facilitators to adherence. This study used a cross-sectional survey to determine the prevalence of pain and occurrence of musculoskeletal injuries and disorders. We asked perioperative staff members about their perceived barriers and facilitators to adherence with safety measures. A total of 155 perioperative nurses in one health system completed the online survey (55% response rate). Most (93%) had experienced at least one musculoskeletal injury or disorder or related pain. Years worked as a perioperative nurse and having neck pain were associated with safety measure adherence. The most reported barrier to safety measure adherence was inadequate staffing. Study findings highlight the need for increased attention to the physical workload demands in the perioperative setting.

Comparative analysis of exoscope-assisted spine surgery versus operating microscope: A systematic review

Background

Limitations in the operative microscope (OM)'s mobility and suboptimal ergonomics created the opportunity for the development of the exoscope. This systematic review aims to evaluate the advantages and disadvantages of exoscopes and OMs in spine surgery.

Methods

Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, a systematic search was conducted in the major research databases. All studies evaluating the exoscopes and/or OMs in spinal procedures were included.

Results

There were 602 patients included in the 16 studies, with 539 spine surgery patients, 19 vascular cases, 1 neural pathology case, 19 cranial cases, and 24 tumor pathologies. When examining surgical outcomes with the exoscope, results were mixed. Compared to the OM, exoscope usage resulted in longer operative times in 7 studies, comparable times in 3 studies, and shorter operative times in 3 studies. Two studies found similar lengths of stay (LOS) for both tools, two reported longer LOS with exoscopes, and one indicated shorter hospital LOS with exoscopes. One study reported higher exoscope-related blood loss (EBL), but four other studies consistently showed reduced EBL. In terms of image quality, illumination, dynamic range, depth perception, ergonomics and cost-effectiveness, the exoscope was consistently rated superior, while findings across studies were mixed regarding the optical zoom ratio and mean scope adjustment (MSA). The learning curve for exoscope use was consistently reported as shorter in all studies.

Conclusion

Exoscopes present a viable alternative to OMs in spine surgery, offering multiple advantages, which supports their promising role in modern neurosurgical practice.

Surgical Posture with Microscopic Versus Exoscopic Visualization in Anterior Cervical Procedures

BACKGROUND

Surgeons sustain deviated postures during procedures even with the use of loupes or an operative microscope. The surgical exoscope is a new intraoperative visualization technology designed to improve surgical ergonomics; however, no objective data exist to say that surgeon posture is significantly improved. This study aimed to quantify the difference in posture during standard anterior cervical spine procedures performed with the aid of an operative microscope versus an exoscope.

METHODS

This was a prospective cohort study utilizing a posture-sensing device at the surgeon's cervicothoracic junction. The primary outcome was the proportion of time under scope spent in a deviated posture, defined as greater than 10 degrees of deviation from neutral in the x- and y-axes (flexion/extension and lateral bending) of the surgeon's upper torso. Average deviation from baseline for the x-, y-, and z-axes (flexion/extension, lateral bending, and axial rotation, respectively), as well as the percentage of operative time spent with the visualization aid was also analyzed.

RESULTS

Overall, 37 anterior cervical procedures were recorded: 18 were performed with an exoscope and 19 with a microscope. Surgeons spent significantly more time in the deviated posture with the operative microscope than with the exoscope (32% vs. 8% with x-axis >10 deg, P <0.005; 20% vs. 6% with y-axis >10 deg, P <0.05). This is also reflected by the significant differences in the average deviation in the x- and y-axes, while under scope.

CONCLUSIONS

Utilizing the exoscope for anterior cervical spine procedures allows surgeons to spend less time in a deviated posture.

Beyond Magnification and Illumination: Ergonomics with a 3D Exoscope in Lumbar Spine Microsurgery to Reduce Musculoskeletal Injuries

OBJECTIVE

The risk of musculoskeletal injuries (MSIs) increases over years of practice which may lead to career-ending among surgeons. Exoscopes represent a new generation of imaging systems that help surgeons operate in a more comfortable posture. This article aimed to assess advantages and limitations, especially ergonomics with a 3D exoscope in lumbar spine microsurgery versus an operating microscope (OM) to reduce MSIs.

METHODS

From March 2018 to May 2020, 90 patients with lumbar disc herniation undergoing a single-level minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) procedure were included. Forty-seven patients were operated with the assistance of the exoscope and 43 patients were operated with the assistance of the OM. Clinical data, magnification, and illumination were evaluated. In particular, the ergonomics of surgeons was evaluated by a questionnaire (subjective) and a rapid entire body assessment (REBA; objective).

RESULTS

The postoperative outcomes were reasonably well balanced between the two groups. The handling of the exoscope was comparable to that of the OM. The depth perception, image quality, and illumination of the exoscope were inferior to those of the OM in MIS-TLIF with long and deep approaches. The educational and training function of the exoscope was superior to that of the OM. Importantly, surgeons rated the ergonomics of the exoscope as very high on the questionnaire and the REBA to the OM (P = 0.017).

CONCLUSIONS

This study showed that the exoscope was a safe and effective alternative to the OM for assisting the MIS-TLIF procedure with the unique advantage of ergonomics to reduce musculoskeletal injuries.

First-in-Human Integrated Use of a Dedicated Microsurgical Robot with a 4K 3D Exoscope: The Future of Microsurgery

Innovative techniques can help overcome the limitations of the human body. Operating on very small structures requires adequate vision of the surgical field and precise movements of sophisticated instruments. Both the human eye and hand are limited when performing microsurgery. Conventional microsurgery uses operation microscopes to enhance the visualization of very small structures. Evolving technology of high-definition 3D cameras provides the opportunity to replace conventional operation microscopes, thereby improving ergonomics for surgeons. This leaves the human hand as a limiting factor in microsurgery. A dedicated robot for microsurgery has been developed to overcome this limitation and enhance the precision and stability of the surgeons’ hands. We present the first-in-human case in reconstructive microsurgery where both technologies are integrated using a dedicated microsurgical robot in combination with a 4K 3D exoscope.

Ergonomics Workshop Improves Musculoskeletal Symptoms in General Surgery Residents

INTRODUCTION

Poor operative ergonomics can lead to muscle fatigue and injury. However, formal ergonomics education is uncommon in surgical residencies. Our study examines the prevalence of musculoskeletal (MSK) symptoms, baseline ergonomics knowledge, and the impact of an ergonomics workshop in general surgery residents.

METHODS

An anonymous voluntary presurvey and postsurvey was distributed to all general surgery residents at a single academic residency, assessing resident characteristics, MSK symptoms, and ergonomic knowledge before and after an ergonomics workshop. The workshop consisted of a lecture and a personalized posture coaching session with a physiatrist.

RESULTS

The presurvey received 33/35 (94%) responses. Of respondents, 100% reported some degree of MSK pain. Prevalence of muscle stiffness and fatigue decreased with increasing height. Females reported higher frequencies of MSK pain (P = 0.01) and more muscle fatigue than males (100% versus 73%, P = 0.03). All residents reported little to no ergonomics knowledge with 68% reporting that ergonomics was rarely discussed in the operating room. The postsurvey received 26/35 (74%) responses. Of respondents, 100% reported the workshop was an effective method of ergonomics education. MSK symptom severity improved in 82% of residents. Reports that ergonomics was rarely discussed in the operating room significantly decreased to 22.8% of residents (P < 0.01).

CONCLUSIONS

Surgical resident ergonomics knowledge is poor and MSK symptoms are common. Resident characteristics are associated with different MSK symptoms. Didactic teaching and personalized posture coaching improve ergonomics knowledge and reduce MSK symptom severity. Surgical residencies should consider implementing similar interventions to improve resident wellbeing.

Prevalence, Prevention, and Treatment of Work-Related Musculoskeletal Disorders Among Microsurgeons

BACKGROUND

 While work related musculoskeletal disorders have been well recognized among all surgeons, and microsurgeons in particular; their prevention and treatment are presently unknown. Our study aims to define the impact of musculoskeletal ailments on microsurgeons and investigate trends in microsurgeon musculoskeletal injury treatment.

METHODS

 An electronic survey was sent to all members of the American Society of Reconstructive Microsurgery. The survey solicited surgeon demographics, microsurgical volume, equipment usage, history of musculoskeletal injury, impact of injury, and interventions / treatment modalities used to address / prevent these issues.

RESULTS

 Of the 883 microsurgeons surveyed, 203 responded (23% response rate). The average age was 45 years (IQR 39-52 years). Most microsurgeons were male (80.8%). Musculoskeletal injury or symptoms related to microsurgery were reported by 137 respondents (67.0%). Fifty surgeons (37.9%) reported that their musculoskeletal injury had adversely affected their practice. Formal medical intervention was sought by 53 respondents (26.1%), with 17 surgeons (8.4%) undergoing surgical intervention. Self-treated was used by 127 microsurgeons (62.6%) for musculoskeletal ailments. Preventative treatments such as strength training, stretching, yoga, massages, and diet were the most beneficial, each with utilization scores of 4 out of 5.

CONCLUSION

 A majority of microsurgeons experience musculoskeletal injury, and some even require surgery to treat their musculoskeletal pathology. Prophylactic practices such as strength training, stretching, yoga, massages, and diet maintenance, are the superior treatment for musculoskeletal injury. Microsurgeons should incorporate training routines in their lives as injury prophylaxis to improve their career longevity and patient care.

Surgical ergonomics: Assessment of surgeon posture and impact of training device during otolaryngology procedures

Objective

To identify factors associated with cervical-thoracic spine posture in otolaryngology surgeries and evaluate the efficacy of a commercially available posture-training device in enhancing surgeon ergonomics.

Methods

Over 3 months, neck and spine posture from individuals performing otolaryngology surgeries was recorded using UpRight Go 2™. Average baseline posture was first recorded and biofeedback was later introduced to attempt to correct posture. The proportion of time spent in upright/neutral cervical-thoracic spine posture was correlated with surgeon and procedure characteristics and compared to proportion of upright posture time after biofeedback intervention.

Results

The proportion of upright operating time was significantly different between procedure subtypes and surgical approaches with best performance in rhinology procedures and worst performance in head and neck surgeries (90% vs. 62%; both p < .001). Female gender, shorter stature, and use of sitting stools were associated with greater proportion of surgery spent upright (all p < .05). Loupes use was associated with less time in upright posture (p < .001). With biofeedback intervention, 8 of 10 subjects demonstrated an average of 5% improvement in operating upright, with most improvement found when performing laryngology procedures (7%) and least improvement in head and neck procedures (2%).

Conclusions

While surgeon posture varies across otolaryngology surgeries, sitting and minimizing the use of loupes may help promote a more ergonomic operating environment and improve surgeon posture. Although the efficacy of biofeedback intervention from a commercially available posture-training device differs among otolaryngologists, exploration of alternative interventions and incorporation of an ergonomics curriculum is warranted to address postural issues experienced by many surgeons.

Reduction of Work-Related Musculoskeletal Disorders in Plastic Surgeons by Introduction of a Posture Training Device

BACKGROUND

Plastic surgeons have an increased risk for the development of musculoskeletal disorders because of frequent poor ergonomics of the operating room. This study characterizes selected plastic surgery procedures, with an attempt to identify high-risk procedures and procedural components as well as the impact of biofeedback on surgical ergonomics.

METHODS

A commercially available posture training device was used to initially record neck and spine positioning and later to send biofeedback to prompt surgeons to correct posture. Device data were correlated with in-person observations to characterize factors associated with more time spent in the slouched/nonneutral cervical and thoracic spine posture.

RESULTS

The proportion of time spent in the upright position during surgery was significantly different among male and female participants, level of training, participant height, in the sitting versus nonsitting positioning (P < 0.001), with loupes use, and if there was more than an 8-inch height difference between 2 participants (mean, 0.70 ± 0.285). Using the device intervention, all participants spent a larger proportion of operating time upright. Half of these improvements in posture were statistically significant. While in feedback mode, participants experienced shorter and more frequent periods of slouching/nonneutral posture. When comparing the same participant performing the same procedure with and without device biofeedback, 72.2% of participants spent more time in the upright/neutral posture during the surgery when the device was sending feedback.

CONCLUSIONS

Biofeedback devices used in the operating room can lead to improved surgical posture, which may translate to reduction of workplace injuries, and overall physician health. This study found that a commercially available posture training device and sitting stools in the operating room could significantly improve physician cervical and thoracic spine posture.

Single-Center Experience Using a 3D4K Digital Operating Scope System for Aneurysm Surgery

BACKGROUND

In recent years, 3D4K exoscope systems (EXs) have been introduced to microneurosurgery and reported to be an alternative to conventional operating microscopes (OMs). This study reviews our single-center experience using an 3D4K EX in intracranial aneurysm surgery.

OBJECTIVE

To investigate the applicability of a novel 3D4K EX for intracranial aneurysm surgery.

METHODS

A retrospective analysis of patients who underwent microsurgical repair of incidentally or ruptured cerebral aneurysms between August 2018 and August 2020 was performed. Patient and aneurysm characteristics and technical features, including 3-dimensional indocyanine green fluorescence, were evaluated. Data on surgery duration were statically assessed for a time trend and comparability with the OM cohort.

RESULTS

Overall, we collected 185 aneurysm cases in which the exoscope was used in 44 cases. The mean duration of surgery using the EX was in similar range to those using the OM (165.5 ± 45.8 minutes vs 160.5 ± 39.2 minutes, P > .05). Routine postoperative computed tomography angiography showed comparable rates of complete aneurysm occlusion (95.5% vs 92.2%, P > .05) and postoperative complications (9.1% vs 9.7%, P > .05). There was no necessity to revert to the OM from the EX. Three-dimensional indocyanine green fluorescence was used in all procedures without any malfunction.

CONCLUSION

The 3D4K EX for vascular microsurgical cases proved to be as useful as the OM. Because of the ease of use and comparable surgical results, the EX has the potential to become an accepted and additional visualization tool in vascular microsurgery next to the OM.

Evaluating the Current State of Ergonomics Education Offered to Students in US Medical Students

BACKGROUND

The high rate of work-related musculoskeletal disorders (WMSD) among surgeons is well-documented and found to factor into medical students' interest in surgical specialties. Ergonomic techniques can reduce musculoskeletal pain in surgeons. Access to ergonomics education in residency is minimal and the ergonomics education offered in medical school has not been characterized.

METHODS

An anonymous, online survey was distributed to 210 administrators in medical education and curriculum at all accredited US allopathic medical schools. They were asked about their knowledge of ergonomics, assessment of potential benefits of ergonomics education to their students, and the ergonomics education offered at their institution.

RESULTS

A total of 71 surveys were completed (33.8% response rate). 82% of schools reported familiarity with the study of ergonomics and 81% thought it would be beneficial to the future careers of their students to receive ergonomics education. Respondents estimated 43% of surgeons experience WMSDs and those that did not think ergonomics education would be beneficial to their students' future careers had a statistically significantly lower estimate of WMSD burden amongst practicing surgeons. Only one respondent reported that students at their institution receive greater than three hours of ergonomics education, while 98% reported their students will receive less than three hours. Considering this, 81% of respondents reported that students do have access to other resources that encourage ergonomic practices, such as gym access, yoga classes, and surgical simulation labs.

DISCUSSION

Medical schools should increase access to ergonomics education and integrate it into their curriculum as early as possible.

Ergonomics Among Craniofacial Surgeons: A Survey of Work-Related Musculoskeletal Discomfort and Injury

INTRODUCTION

Surgical procedures with loupe magnification, headlights, and microscopes expose craniofacial surgeons to mechanical stress that can increase risk of long-term musculoskeletal pain and injury. Identifying the prevalence and cause of work-related musculoskeletal discomfort may guide preventative strategies to prolong well-being, job satisfaction, and greater duration of surgical careers.

METHODS

A 29-question online survey was distributed to the surgeon members of the American Cleft Palate-Craniofacial Association. Eight hundred seventy-three surveys were distributed, and the anonymous responses were recorded using Google forms.

RESULTS

One hundred ninety-six unique responses were recorded (22.5% response rate). A total of 64.2% reported experiencing musculoskeletal symptoms during their career, with neck, lower back, and shoulders being the most common problem areas. Multivariate analysis demonstrated surgical loupes (odds ratio 2.36, P = 0.03) and length of surgical practice >15 years (odds ratio 1.95, P = 0.04) were independently associated with greater odds of developing symptoms. Headlights (median pain = 3, P < 0.001), loupes (median pain = 3.5, P < 0.001), and operative microscope use (median pain = 2, P = 0.02) were all associated with higher pain while operating. A total of 52.5% respondents sought medical treatments, 50.5% were concerned musculoskeletal discomfort would affect their careers, 56.6% reported a colleague that required an operation, and 30.2% reported a colleague on temporary or permanent disability.

CONCLUSIONS

Craniofacial surgery often involves long procedures, use of surgical adjuncts, and ergonomically straining postures, which can lead to musculoskeletal discomfort and injury. This under-reported and important phenomenon merits candid conversation and active preventative strategies to prolong surgical careers, improve professional satisfaction, and maximize patient safety.

Performance of microvascular anastomosis with a new robotic visualization system: proof of concept

Microvascular procedures require visual magnification of the surgical field, e.g. by a microscope. This can be accompanied by an unergonomic posture with musculoskeletal pain or long-term degenerative changes as the eye is bound to the ocular throughout the whole procedure. The presented study describes the advantages and drawbacks of a 3D exoscope camera system. The RoboticScope^®-system (BHS Technologies^®, Innsbruck, Austria) features a high-resolution 3D-camera that is placed over the surgical field and a head-mounted-display (HMD) that the camera pictures are transferred to. A motion sensor in the HMD allows for hands-free change of the exoscope position via head movements. For general evaluation of the system functions coronary artery anastomoses of ex-vivo pig hearts were performed. Second, the system was evaluated for anastomosis of a radial-forearm-free-flap in a clinical setting/in vivo. The system positioning was possible entirely hands-free using head movements. Camera control was intuitive; visualization of the operation site was adequate and independent from head or body position. Besides technical instructions of the providing company, there was no special surgical training of the surgeons or involved staff upfront performing the procedures necessary. An ergonomic assessment questionnaire showed a favorable ergonomic position in comparison to surgery with a microscope. The outcome of the operated patient was good. There were no intra- or postoperative complications. The exoscope facilitates a change of head and body position without losing focus of the operation site and an ergonomic working position. Repeated applications have to clarify if the system benefits in clinical routine.

Ergonomic Challenges in the Perioperative Setting

Working in health care can be physically stressful. The perioperative setting, which is largely concealed from other health care workers and the general public, places unique physical demands on its workers. Perioperative personnel are responsible for a variety of physical tasks, including moving and positioning patients, holding extremities, and moving equipment and supplies. As the nursing workforce ages, the physical demands of the perioperative environment may affect the development of musculoskeletal disorders in older nurses. The purpose of this article is to review published research and describe the ergonomic challenges of working in the OR. There currently is a paucity of literature on the effects of ergonomic risk factors on perioperative nurses in the United States. This article also provides some recommendations for perioperative staff members and leaders that may assist them with creating and maintaining a healthy and safe work environment.

Cervical spine microsurgery with the high-definition 3D exoscope: advantages and disadvantages

OBJECTIVE

The aim of this study was to evaluate our experience with a high-definition three-dimensional (3D) exoscope (EX) for cervical spine surgery versus a binocular operating microscope (OM).

METHODS

A retrospective review of patients undergoing a single-level anterior cervical discectomy and fusion (ACDF) procedure for the treatment of cervical myelopathy from March 2019 to May 2020 was performed. Demographic, perioperative, and clinical outcomes of 50 patients were included, 23 of whom received assistance from the 3D exoscope (EX group) and 27 of whom received assistance from the OM (OM group). Operative baseline and postoperative outcome parameters were evaluated. Periprocedural handling, visualization, and illumination by the EX, as well as surgeons' ergonomics, were scored using a questionnaire and rapid upper limb assessment (RULA).

RESULTS

Baseline characteristics were similar between the two groups. There were no significant differences between groups in mean operative time, blood loss, duration of admission, or postoperative improvement of symptoms. Both groups showed similar clinical improvements after surgery. There were no intraoperative complications in either group. According to the attending surgeons, the intraoperative handling of instruments for the EX was rated to be comparable to that of the OM. Surgeons rated the comfort level of the intraoperative posture for the EX as very high on the subjective questionnaire and equal to the OM on the objective RULA. When compared with the OM, depth perception, image quality, and illumination for the EX were rated as inferior in ACDF procedures with long approaches. The operative education and training function of the EX was rated to be superior to that of the OM.

CONCLUSIONS

Overall, our study showed that the EX appears to be a safe alternative for common ACDF with the unique advantage of excellent comfort and also serves a useful educational tool for the surgical team. However, our investigation revealed several important limitations of this system, including slightly inferior visualization and illumination quality compared with the OM.

Incorporating Surgical Ergonomics Education into Surgical Residency Curriculum

BACKGROUND

Education on surgical ergonomics during residency training is lacking. This study aimed to determine the feasibility and impact of incorporating surgical ergonomics lectures into residency curriculum.

METHODS

A survey was distributed to 42 residents with questions regarding demographics, surgical factors, prevalence of musculoskeletal (MSK) symptoms, and awareness of ergonomic recommendations. The residents then received 2 lectures on ergonomics in surgery. A follow up survey was distributed to evaluate the impact of the lectures.

RESULTS

Twenty-two residents completed the presession survey. Ninety-one percent reported MSK symptoms attributed to their training. Seventeen residents completed the follow up survey. All reported increased awareness of their own habits while operating and improved understanding of methods to prevent and/or treat work-related injuries. All residents recommended incorporating the lectures as an adjunct to their regular curriculum.

CONCLUSIONS

The rates of MSK symptoms and/or injury are high among surgeon trainees. Residency is an opportune time to educate on principles of ergonomics and may prevent future injuries.

Clinical implementation of a 3D4K-exoscope (Orbeye) in microneurosurgery

Exoscopic surgery promises alleviation of physical strain, improved intraoperative visualization and facilitation of the clinical workflow. In this prospective observational study, we investigate the clinical usability of a novel 3D4K-exoscope in routine neurosurgical interventions. Questionnaires on the use of the exoscope were carried out. Exemplary cases were additionally video-documented. All participating neurosurgeons (n = 10) received initial device training. Changing to a conventional microscope was possible at all times. A linear mixed model was used to analyse the impact of time on the switchover rate. For further analysis, we dichotomized the surgeons in a frequent (n = 1) and an infrequent (n = 9) user group. A one-sample Wilcoxon signed rank test was used to evaluate, if the number of surgeries differed between the two groups. Thirty-nine operations were included. No intraoperative complications occurred. In 69.2% of the procedures, the surgeon switched to the conventional microscope. While during the first half of the study the conversion rate was 90%, it decreased to 52.6% in the second half (p = 0.003). The number of interventions between the frequent and the infrequent user group differed significantly (p = 0.007). Main reasons for switching to ocular-based surgery were impaired hand–eye coordination and poor depth perception. The exoscope investigated in this study can be easily integrated in established neurosurgical workflows. Surgical ergonomics improved compared to standard microsurgical setups. Excellent image quality and precise control of the camera added to overall user satisfaction. For experienced surgeons, the incentive to switch from ocular-based to exoscopic surgery greatly varies.

Ergonomics in IR

Ergonomic research in the field of interventional radiology remains limited. Existing literature suggests that operators are at increased risk for work-related musculoskeletal disorders related to the use of lead garments and incomplete knowledge of ergonomic principles. Data from existing surgical literature suggest that musculoskeletal disorders may contribute to physician burnout and female operators are at a higher risk of developing musculoskeletal disorders. This review article aims to summarize the existing ergonomic challenges faced by interventional radiologists, reiterate existing solutions to these challenges, and highlight the need for further ergonomic research in multiple areas, including burnout and gender.

Stretching and Strength Training to Improve Postural Ergonomics and Endurance in the Operating Room

Plastic surgeons report the highest prevalence of chronic musculoskeletal pain and fatigue among surgical subspecialties. Musculoskeletal pain impacts daily life, career longevity, and economic burden secondary to occupational injury. Poor postural awareness and ergonomic set up in the operating room represent the most common etiology.

Methods

A literature review was performed to highlight the ergonomic set-up, postural pitfalls, occupational injuries, and musculoskeletal pain in the operating room. An institutional survey was administered among resident and attending surgeons regarding musculoskeletal pain, posture, ergonomic education, and future improvements. Literature results, survey data, and intraoperative photographs were analyzed in collaboration with physical therapists and personal trainers.

Results

Survey results demonstrated that 97% of resident and attending respondents experienced musculoskeletal pain and 83% reported a lack of education in posture and ergonomics. The main postural pitfalls included head forward and flexed positioning, abduction and internal arm rotation, and kyphosis of the thoracic spine. The collaborators developed instructional videos to assess posture and biomechanics and demonstrate targeted stretching and strength exercises to address specific neck, back, and shoulder pain.

Conclusions

Poor posture is unavoidable in the operating room at times. These educational videos should be utilized for self-motivated and prophylactic conditioning outside of the operating room to maintain physical well-being throughout a career in plastic surgery. Future focus should be aimed at implementing dedicated ergonomic education and physical wellness programs early in surgical resident training.

No Longer a Pain in the Neck: Use of Operating Microscope for Palatoplasty

For craniofacial surgeons, cleft palate repair is an intricate and difficult operation positionally. Historically, use of loupe magnification and a headlight can cause significant strain to the surgeon's neck and, at times, subpar optics for both the operator and the assistant. The use of an operating microscope was first advocated by Sommerlad in 2003. By using the operating microscope for cleft palate closure, there are improved ergonomics for the surgeon and assistant by allowing for straight in-line back and neck posture with excellent visualization of the surgical field for the entire surgical team. The available zoom and focus improve the ability to isolate and repair the levator veli palatini muscle. Proper posture with a neutral cervical spine will help prolong a surgeon's career and ability to care for their patients.

Musculoskeletal Pain Survey Outcomes in Cleft Surgeons and Orthodontists

OBJECTIVE

Determine prevalence and characteristics of musculoskeletal pain and pathology in cleft providers.

DESIGN

An IRB-exempt survey based on previously validated surveys was administered. Data collected included demographics, practice description, musculoskeletal pain history, formal diagnoses, and interventions.

SETTING

Survey was sent to all cleft centers approved by the American Cleft Palate-Craniofacial Association worldwide.

PATIENTS, PARTICIPANTS

All cleft surgeons and orthodontists at these centers met entry criteria. Eighty-three providers responded. Cleft center coordinators were unable to confirm the number of survey recipients.

MAIN OUTCOME MEASURES

The hypothesis formulated prior to data collection was that prevalence would be comparable to general plastic surgeons and other at-risk health care providers.

RESULTS

Average age of respondents was 49.8 ± 11.3 years; 33.9% of respondents were female. Average body mass index was 24.8 ± 3.5 kg/m². Headaches were observed in 62.7% of surveyed respondents while musculoskeletal symptoms were reported in 89.8%. Of the 12 body parts addressed, most commonly affected were the neck (71.2%), shoulders (52.5%), and lower back (67.8%). Pain interfered with hobbies and home life in the majority of respondents (62.7%). Those who reported a formal diagnosis were more likely to undergo treatment including surgery (P < .01), medication (P = .03), and physical therapies (P < .01).

CONCLUSIONS

Cleft surgeons and orthodontists experience a higher frequency of headaches compared to the general population, and musculoskeletal disorders are more prevalent than reported by general plastic surgeons. Pain interferes with hobbies and home life. Formal diagnosis leads to treatment. Preventative exercises and interventions are presented.

Spine surgery is kyphosing to spine surgeon

BACKGROUND

Spine surgery is a demanding surgical specialty which requires surgeons to operate for hours on end, often compromising good posture. Sustained poor posture in the operating room (OR) can be the source of many adverse health effects on spine surgeons. This study will analyze posture of a spine surgeon in different types of spine surgery cases.

METHODS

Posture of a surgeon was measured using the UPRIGHT Posture Training Device. The device was worn by the surgeon in the OR through a wide variety of spine surgery cases.

RESULTS

The percent time spent slouched while performing cervical, adult deformity, and lumbar spine surgeries is 39.9, 58.9, and 38.6, respectively. For all surgeries recorded, the percent time slouched is 41.6. The average procedure time was 145.3 min, with adult deformity cases on average being the longest (245.6 min) followed by cervical (152.9 min) and then lumbar (122.5 min).

CONCLUSION

Poor posture while operating is very likely to occur for many spine surgeons regardless of case type. This poor posture is maintained for long periods of time given the average spine surgery procedure recorded in the study was roughly 2.5 h long. Spine surgeons should be aware of the tendency for poor posture while operating, and they should try using posture-improving techniques to maintain good spine health.

Ergonomics and Related Physical Symptoms Among Neurosurgeons

OBJECTIVE

Work-related musculoskeletal disorders (WMSDs) among neurosurgeons can lead to consequences for themselves, the hospital, and society. In the current study, the working conditions of neurosurgeons from an ergonomic point of view is evaluated, together with WMSD.

METHODS

Members of the Congress of Neurological Surgeons were surveyed with an online survey covering 1) demographics, 2) working conditions, 3) ergonomic features during 3 neurosurgical procedures, and 4) whether they experienced WMSD. Multivariate logistic regression analysis was performed to identify factors associated with experiencing WMSD.

RESULTS

In total, 417 replies were received. Respondents had a mean tenure of 21.9 years. In total, 33.1% stated that the operating room is furnished ergonomically and 90.7% stated that ergonomics is an underexposed field in neurosurgery. The majority of the respondents (73.6%) had experienced WMSD. Performing long procedures and spine surgery were mentioned most often as cause for WMSD. Due to WMSD, 11.3% of the respondents had to take time off work, and 14.2% considered changing their career. Analgesics were mostly used as treatment for WMSD (42.9%) and 7.4% underwent surgery. Having a tenure ≤15 years and having the operating room furnished ergonomically were associated with less WMSD in univariate analysis, whereas only a tenure <15 years was in multivariate analysis (odds ratio 0.27; 95% confidence interval 0.085-0.831).

CONCLUSIONS

Despite only a minority of the surgeons taking time off due to WMSD, the majority suffers from WMSD. Education of residents in ergonomics to prevent WMSD in their later careers and ergonomic furnishing of surgical instrumentation and operating rooms seem to be areas for improvement.
