Thomason HC, Redmond J, Morrison JC, Fawley D, Bernard T, Gladnick BP. Use of an Automated Surgical Impactor Reduces Femoral Broaching Time in Direct Anterior Approach Total Hip Arthroplasty: Results From a Randomized, Multicenter Study. Arthroplast Today 2024; 28:101480. [PMID: 39188566 PMCID: PMC11345505 DOI: 10.1016/j.artd.2024.101480] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2024] [Revised: 05/21/2024] [Accepted: 06/30/2024] [Indexed: 08/28/2024] Open
Abstract
Background Impaction in total hip arthroplasty has typically been conducted using a mallet. A surgical automated impactor has been developed with the goal of reducing surgeon variability, fatigue, and injury. There is also potential to reduce the variability of each impaction step in which automated impaction is used, through reproducible and consistent application of force. Methods Patients were randomized into either the mallet control group, or the automated impaction study group (1:1 randomization). The primary endpoint analysis was conducted to demonstrate that femoral broaching time (in minutes) with an automated impactor is noninferior to femoral broaching time with manual instruments (mallet) under a noninferiority (NI) margin of 1.25 minutes, with a subsequent test of superiority. A total of 218 patients were randomized and treated (109 in each group). Results Mean femoral broaching time was 5.8 minutes in the automated impaction study group (automated), and 8.1 minutes in the mallet control group (mallet), a 28.4% reduction (P = .0005). However, there was not a difference in surgery duration between the groups. Three fractures were reported in the mallet group and 1 in the automated group. Conclusions In this randomized multicenter study, an automated impactor was shown to reduce femoral broaching time in primary total hip arthroplasty, with no increase in fractures, but no decrease in operating room time was noted.

Abstract
Aims Manual impaction, with a mallet and introducer, remains the standard method of installing cementless acetabular cups during total hip arthroplasty (THA). This study aims to quantify the accuracy and precision of manual impaction strikes during the seating of an acetabular component. This understanding aims to help improve impaction surgical techniques and inform the development of future technologies. Methods Posterior approach THAs were carried out on three cadavers by an expert orthopaedic surgeon. An instrumented mallet and introducer were used to insert cementless acetabular cups. The motion of the mallet, relative to the introducer, was analyzed for a total of 110 strikes split into low-, medium-, and high-effort strikes. Three parameters were extracted from these data: strike vector, strike offset, and mallet face alignment. Results The force vector of the mallet strike, relative to the introducer axis, was misaligned by an average of 18.1°, resulting in an average wasted strike energy of 6.1%. Furthermore, the mean strike offset was 19.8 mm from the centre of the introducer axis and the mallet face, relative to the introducer strike face, was misaligned by a mean angle of 15.2° from the introducer strike face. Conclusion The direction of the impact vector in manual impaction lacks both accuracy and precision. There is an opportunity to improve this through more advanced impaction instruments or surgical training.

High Prevalence of Work-related Musculoskeletal Disorders and Limited Evidence-based Ergonomics in Orthopaedic Surgery: A Systematic Review. Clin Orthop Relat Res 2024; 482:659-671. [PMID: 37987688 PMCID: PMC10936985 DOI: 10.1097/corr.0000000000002904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 09/29/2023] [Indexed: 11/22/2023]
Abstract
BACKGROUND The Centers for Disease Control defines work-related musculoskeletal disorders as disorders of the nerves, muscles, tendons, joints, spinal discs, and cartilage that are caused or exacerbated by the environment or nature of work. Previous meta-analyses have characterized work-related musculoskeletal disorders among interventionists, general surgeons, and other surgical subspecialties, but prevalence estimates, prognosis, and ergonomic considerations vary by study and surgical specialty. QUESTIONS/PURPOSES (1) What is the career prevalence of work-related musculoskeletal disorders in orthopaedic surgeons? (2) What is the treatment prevalence associated with work-related musculoskeletal disorders in orthopaedic surgeons? (3) What is the disability burden of work-related musculoskeletal disorders in orthopaedic surgeons? (4) What is the scope of orthopaedic surgical ergonomic assessments and interventions? METHODS A systematic review of English-language studies from PubMed, MEDLINE, Embase, and Scopus was performed in December 2022 and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies that presented prevalence estimates of work-related musculoskeletal disorders or assessed surgical ergonomics in orthopaedic surgery were included. Reviews, case reports, gray literature (conference abstracts and preprints), and studies with mixed-surgeon (nonorthopaedic) populations were excluded. The search yielded 5603 abstracts; 24 survey-based studies with 4876 orthopaedic surgeons (mean age 48 years; 79% of surgeons were men) were included for an analysis of work-related musculoskeletal disorders, and 18 articles were included for a descriptive synthesis of ergonomic assessment. Quality assessment using the Joanna Briggs Institute Tool revealed that studies had a low to moderate risk of bias, largely because of self-reporting survey-based methodology. Because of considerable heterogeneity and risk of bias, prevalence outcomes were not pooled and instead are presented as ranges (mean I 2 = 91.3%). RESULTS The career prevalence of work-related musculoskeletal disorders in orthopaedic surgeons ranged from 37% to 97%. By anatomic location, the prevalence of work-related musculoskeletal disorders in the head and neck ranged from 4% to 74%; back ranged from 9% to 77%; forearm, wrist, and hand ranged from 12% to 54%; elbow ranged from 3% to 28%; shoulder ranged from 3% to 34%; hip and thigh ranged from 1% to 10%; knee and lower leg ranged from 1% to 31%; and foot and ankle ranged from 4% to 25%. Of orthopaedic surgeons reporting work-related musculoskeletal disorders, 9% to 33% had a leave of absence, practice restriction or modification, or early retirement, and 27% to 83% received some form of treatment. Orthopaedic surgeons experienced biomechanical, cardiovascular, neuromuscular, and metabolic stress during procedures. Interventions to improve orthopaedic surgical ergonomics have been limited, but have included robotic assistance, proper visualization aids, appropriate use of power tools, and safely minimizing lead apron use. In hip and knee arthroplasty, robotic assistance was the most effective in improving posture and reducing caloric expenditure. In spine surgery, proper use of surgical loupes was the most effective in improving posture. CONCLUSION Although the reported ranges of our main findings were wide, even on the low end of the reported ranges, work-related musculoskeletal disability among orthopaedic surgeons appears to be a substantial concern. We recommend that orthopaedic residency training programs incorporate surgical ergonomics or work injury lectures, workshops, and film review (alongside existing film review of surgical skills) into their curricula. We suggest hospitals engage in shared decision-making with surgeons through anonymous needs assessment surveys to implement wellness programs specific to surgeons' musculoskeletal needs. We urge institutions to assess surgeon ergonomics during routine quality assessment of novel surgical instruments and workflows. LEVEL OF EVIDENCE Level III, prognostic study.

Abstract
Background This radiological study aims to assess the prevalence of lateral elbow pathology in an asymptomatic population using 3.0T magnetic resonance imaging (MRI). Methods Bilateral elbow MRI was undertaken in 30 asymptomatic volunteers. Exclusion criteria included elbow pain within 3 months, elbow trauma or previous diagnosis of lateral epicondylar tendinopathy. Baseline patient-reported outcome measures were recorded along with age and body mass index (BMI). Two musculoskeletal radiologists independently graded the degree of abnormality at the common extensor tendon. Results Thirty volunteers were categorised according to age; 35-44 (n = 10), 45-54 (n = 11), and 55-65 (n = 9) with a 1:1 male-to-female ratio. Radiological evidence of tendon abnormality was found in 37% of volunteers. The proportion with abnormal findings increased with age; 35-44 (10%), 45-54 (36%), 55-65 (67%) and BMI; 18-24.9 (23%), 25-29.9 (43%), > 30 (67%). Changes were generally 'mild' or 'moderate', with a single volunteer showing 'severe' pathology. Kappa for the radiographic agreement was 0.91 (0.83-0.98). Discussion This study has demonstrated MRI findings suggestive of pathology at the common extensor tendon to be prevalent in an asymptomatic population, increasing with age and BMI. This draws into question the diagnostic and prognostic value of MRI imaging in lateral epicondylar tendinopathy, especially in older patients.

J Arthroplasty 2024; 39:527-532. [PMID: 37572723 DOI: 10.1016/j.arth.2023.08.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 08/02/2023] [Accepted: 08/04/2023] [Indexed: 08/14/2023] Open
Abstract
BACKGROUND Arthroplasty is one of the least gender-diverse orthopaedic subspecialties. While previous studies have looked at factors influencing fellowship choices for women, few studies have attempted to understand the decision for or against arthroplasty specifically. Working to better understand fellowship choice is a critical step in the process of increasing women recruitment. METHODS An anonymous survey was distributed using REDCap to women orthopaedic surgeons and trainees through listservs, social media groups, and residency programs. Surgeons who had decided on a specific subspecialty or already completed fellowship were included. Responses were obtained from 164 surgeons (72 arthroplasty surgeons, 92 other subspecialties). Chi-squared and Fisher's Exact tests were then performed. RESULTS The most important factor for those who chose arthroplasty was enjoyment of the surgeries. The biggest concerns from those in the arthroplasty group about the field were work-life balance, ability to become pregnant and/or have a healthy pregnancy, and sex bias from referring physicians. Of those who ultimately chose another subspecialty, 30.4% considered arthroplasty "a little" and 8.7% considered it "strongly." The most important dissuaders for the group that considered arthroplasty were concerns about "boy's club" culture, concerns about the physicality of the surgeries, and a lack of mentors. CONCLUSION While the decision to choose a career path is multifactorial, our hope is that through the identification of modifiable factors we can increase women representation in arthroplasty. Increasing mentorship, implementing practical solutions to improve work-life balance, supporting healthy pregnancies, and mitigating the physical demands of surgery could help address current disparities.

Abstract
Background During manual broaching (MB) in total hip arthroplasty (THA), off-axis forces delivered to the proximal femur and broach malalignment can lead to fractures and cortical perforations. Powered broaching (PB) is a novel alternative that delivers consistent impaction forces and reduces workload. This is the first large-scale study to compare intraoperative and 90-day rates of periprosthetic femur fractures (PFFs) and perforations in THA performed using MB vs PB. Methods Our institutional database was reviewed for all patients undergoing primary cementless direct anterior THA from 2016 to 2021. Three surgeons performing 2048 THAs (MB = 800; PB = 1248) using the same stem design were included. PFFs and perforations within 90 days of the index procedure were compared. Differences in length of surgery and demographics were assessed. Results Calcar fractures occurred in <1% of patients (PB [0.96%, 12/1248] vs MB [0.25%, 2/800]; P = .06). Rates of trochanteric fractures did not differ (PB = 0.32% [4/1248] vs MB = 0.38% [3/800]; P = .84). Cortical perforations occurred in 0.24% (3/1248) of the PB cohort and in 0.75% (6/800) of the MB cohort (P = .09). No revisions due to aseptic loosening or PFF occurred within 120 days of surgery. Conclusions Our single-center experience with powered femoral broaching in THA demonstrates PB is a safe and efficient means of performing direct anterior THA. Low rates (<1%) of PFF, perforation, and revision can be achieved. Given our positive experience with PB, all surgeon authors utilize PB nearly exclusively for elective primary direct anterior THA.

Abstract
Aims As an increasing number of female surgeons are choosing orthopaedics, it is important to recognize the impact of pregnancy within this cohort. The aim of this review was to examine common themes and data surrounding pregnancy, parenthood, and fertility within orthopaedics. Methods A systematic review was conducted by searching Medline, Emcare, Embase, PsycINFO, OrthoSearch, and the Cochrane Library in November 2022. The Preferred Reporting Items for Systematic Reviews and Meta Analysis were adhered to. Original research papers that focused on pregnancy and/or parenthood within orthopaedic surgery were included for review. Results Of 1,205 papers, 19 met the inclusion criteria. Our results found that orthopaedic surgeons have higher reported rates of obstetric complications, congenital abnormalities, and infertility compared to the general population. They were noted to have children at a later age and voluntarily delayed childbearing. Negative perceptions of pregnancy from fellow trainees and programme directors were identified. Conclusion Female orthopaedic surgeons have high rates of obstetric complications and infertility. Negative perceptions surrounding pregnancy can lead to orthopaedic surgeons voluntarily delaying childbearing. There is a need for a pregnancy-positive culture shift combined with formalized guidelines and female mentorship to create a more supportive environment for pregnancy within orthopaedic surgery.

Abstract
PURPOSE Trauma & Orthopaedic (T&O) surgery presents several occupational hazards to pregnant women and the unborn child. National bodies have produced guidelines to mitigate these risks as far as possible but individual trusts must be aware of them and implement them in their local policies. Our study aims to re-assess whether national guidelines for the protection of pregnant women are better adhered to nationally by providing a comparison to a previous study in 2018. METHODS A national observational study of 146 NHS trusts in the UK was conducted. Each trust was asked to complete a freedom of information request regarding all orthopaedic guidelines relating to pregnant theatre staff, which specifically related to the protection of the mother and foetus from exposure to harmful activity in theatre. Compliance was ascertained by cross-checking local policies with national guidelines. RESULTS 82/146 (52.0%) of NHS trusts responded to the Freedom of Information request. 31/75 (41.3%) respondents followed Health and Safety Executive (HSE) guidance for New and Expectant Mothers with 17/75 (22.7%) following multiple national guidelines. 16/75 (21.3%) NHS trusts do not follow any national guidelines in protecting new and expectant mothers from occupational hazards in the orthopaedic theatre setting. CONCLUSIONS Although an improvement has been made since 2018 in complying with national guidelines protecting new and expectant mothers from orthopaedic-related hazards, a sizeable proportion of NHS trusts do not comply with any national guidelines, putting employees at undue risk. There is a continued need for pregnant surgeons to be aware of and seek occupational health advice from dedicated professional bodies if the NHS trust does not provide specific guidance. Simultaneously, a sustained effort must be present to continue to inform NHS employers of their duty to protect new and expectant mothers and signpost them to relevant guidance.

Abstract
The use of robotics in total knee arthroplasty (TKA) is growing at an exponential rate. Despite the improved accuracy and reproducibility of robotic-assisted TKA, consistent clinical benefits have yet to be determined, with most studies showing comparable functional outcomes and survivorship between robotic and conventional techniques. Given the success and durability of conventional TKA, measurable improvements in these outcomes with robotic assistance may be difficult to prove. Efforts to optimize component alignment within two degrees of neutral may be an attainable but misguided goal. Applying the "Wald Principles" of rationalization, it is possible that robotic technology may still prove beneficial, even when equivalent clinical outcomes as conventional methods, if we look beyond the obvious surrogate measures of success. Robotic systems may help to reduce inventory, streamline surgical trays, enhance workflows and surgical efficiency, optimize soft tissue balancing, improve surgeon ergonomics, and integrate artificial intelligence and machine learning algorithms into a broader digital ecosystem. This article explores these less obvious alternative benefits of robotic surgery in the field of TKA.

Abstract
BACKGROUND Orthopaedic surgeons are at high risk for experiencing work-related musculoskeletal (MSK) injuries and chronic pain due to repetitive large magnitude forces, altered posture from lead vests, and prolonged irregular body positions. We sought to synthesize available evidence regarding (1) the biomechanics of orthopaedic surgery and (2) MSK injuries sustained by orthopaedic surgeons with subsequent treatment and consequences. METHODS To conduct this systematic review, we queried 4 databases (PubMed, Embase, MEDLINE, and Web of Science) for original research studies presenting on the biomechanics of orthopaedic surgery or MSK injuries sustained by orthopaedic surgeons. Studies were excluded if they were not original research (i.e., reviews) or reported on non-MSK injuries and injuries in patients or nonorthopaedic specialists. The literature search yielded 3,202 publications, 34 of which were included in the final analysis. RESULTS Eight studies reported on the biomechanics of orthopaedic surgery. Surgeons spent an average 41.6% of operating time slouched. Head and whole spine angles were closest to natural standing position when using a microscope for visualization and with higher surgical field heights. Use of lead aprons resulted in a shifted weight distribution on the forefoot, gain in thoracic kyphosis, and increase in lateral deviation from postural loading. Twenty-six studies reported on MSK symptoms and injuries experienced by orthopaedic surgeons, with an overall prevalence from 44% to 97%. The most common body regions involved were lower back (15.2%-89.5%), hip/thigh (5.0%-86.6%), neck (2.4%-74%), hand/wrist (10.5%-54%), shoulder (7.1%-48.5%), elbow (3.1%-28.3%), knee/lower leg (7.9%-27.4%), and foot/ankle (7%-25.7%). Of surgeons with any reported MSK symptom or injury, 27% to 65.7% required nonoperative treatment, 3.2% to 34.3% surgery, and 4.5% to 31% time off work. Up to 59.3% of surgeons reported that their injuries would negatively influence their ability to perform surgical procedures in the future. CONCLUSIONS The orthopaedic surgeon population experiences a high prevalence of MSK symptoms and injuries, likely secondary to the biomechanical burdens of tasks required of them during strenuous operations.

Abstract
BACKGROUND Occupational injuries are a prevalent and costly problem for orthopedic surgeons, especially arthroplasty surgeons performing physically demanding and repetitive tasks. The purpose of this study was to characterize occupational musculoskeletal injuries in female adult reconstruction surgeons. METHODS A prospective survey about workplace musculoskeletal injuries was distributed to female attending adult reconstruction surgeons in May 2020. Participants were identified using subspecialty membership data, social media, and personal contacts. Results were analyzed using descriptive statistics. RESULTS Of the total 63 female arthroplasty surgeons who responded, 65.1% were 30-45 year old, and 42.9% were within 5 years of practice, 68.3% sustained an occupational musculoskeletal injury, most commonly forearm/wrist/hand (79.1%), shoulder (48.8%), and low back (44.2%); 10.0% of reported occupational injuries not related to pregnancy resulted in the surgeon requiring time off work, while 48.2% required temporary modifications of job performance, and 10.9% required surgical treatment. Of the injured surgeons who reported having been pregnant, 65.4% reported a workplace exacerbation of a pregnancy-related musculoskeletal condition, including low back pain (52.9%), pubic symphysis pain (35.3%), and carpal tunnel syndrome (29.4%). CONCLUSION A total of 68.3% of female arthroplasty surgeons reported occupational musculoskeletal injuries, predominately forearm/wrist/hand, with a portion of those requiring modifications of job performance. Musculoskeletal injuries may be mitigated by performing repetitive tasks ergonomically, correcting posture, using appropriately sized instrumentation, and using automated or lighter instruments, to potentially avoid modifications to job performance, time off work, or even surgical procedures. Further studies should investigate factors that contribute to injuries in arthroplasty surgeons and how they can be prevented.

[PMID: 35633751 PMCID: PMC9125005 DOI: 10.5312/wjo.v13.i5.465] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2021] [Revised: 11/12/2021] [Accepted: 04/24/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The nature of tasks required by hand surgeons require both forceful and repetitive maneuvers, thus subjecting these surgeons to the risk of musculoskeletal (MSK) injuries during their years in practice.
AIM To assess the prevalence, characteristics and impact of MSK disorders among hand surgeons.
METHODS A modified version of the physical discomfort survey was sent to surgeons who were members of the American Society for Surgery of the Hand via e-mail. The collected data were analyzed using descriptive statistics, one-way analysis of variance, and Fisher's exact test. P values of < 0.05 were considered statistically significant.
RESULTS Of the 578 respondents, 60.4% reported that they had sustained a work-related MSK injury, of which the most common diagnoses were lateral elbow epicondylitis (18.7%), low back pain (17.1%) and carpal tunnel syndrome (15.6%). Among those that reported an injury, 73.1 % required treatment and 29.2 % needed time off work as a direct result of their injury. The number of work-related injuries incurred by a surgeon increased significantly with increasing age (P < 0.003), increasing years in practice (P < 0.001) and higher case load (P < 0.05).
CONCLUSION To our knowledge this study is the first of its kind to assess MSK injuries sustained by Hand surgeons with a high incidence. These results should increase awareness on this aspect and fuel future studies directed at preventing these types of work-related injuries, thus minimizing the financial and psychological burden on these surgeons and the healthcare system.

[PMID: 34888149 PMCID: PMC8613686 DOI: 10.5312/wjo.v12.i11.891] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2021] [Revised: 07/28/2021] [Accepted: 09/19/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Work-related injuries have gained recent attention, especially in the orthopaedic literature. As upper extremity orthopaedic surgical tasks require repetitive and constant maneuvers, these surgeons can be at increased risk of acquiring work-related musculoskeletal (MSK) disorders during their years in practice.
AIM To assess the prevalence, characteristics and impact of MSK disorders among upper extremity orthopaedic surgeons.
METHODS A modified version of the physical discomfort survey was sent to surgeons who were members of the American Shoulder and Elbow Surgeons and the Canadian shoulder and elbow society via e-mail. The collected data were analyzed using descriptive statistics, one-way analysis of variance, and Fisher's exact test. P values of < 0.05 were considered statistically significant.
RESULTS Of the 142 respondents, 90.8% were males and the majority were younger than 55 years old (65.5%). A work-related MSK injury was reported by 89.4% of respondents, of which the most common diagnoses were low back pain (26.1%) and lateral elbow epicondylitis (18.3%). Among those that reported an injury, 82.7% required treatment and 26% required time off work as a direct result of their injury. The need to undergo treatment due to the injury was associated with increased number of injuries (P < 0.01). Moreover, surgeons were more likely to require time off work when they had been in practice for > 21 years (P < 0.05).
CONCLUSION A high proportion of surgeons in our survey reported MSK injuries, with more than one quarter of surgeons reported requiring time off work due to an MSK injury. The high incidence of these disorders may place a financial and psychological burden on surgeons and affect their ability to provide patient care. Awareness of operative ergonomics, irrespective of surgical specialty may help to decrease or possibly prevent the occurrence of these disorders.
