Conferences centered around surgery suffers from gender disparity with male faculty having a more dominant presence in meetings compared to female faculty. Orthopedic Surgery possibly suffers the most from this problem of all surgical specialties, and is reflective of a gender disparity in the field. The objective of this study was to investigate the prevalence of “manels”, or male-only sessions, in eight major Orthopedic Surgery meetings hosted in 2021 and to quantify the differences in location of practice, academic position, years of practice, and research qualifications between male and female faculty.

Eight Orthopedic conferences organized by major Orthopedic associations (AAOS, COA, OTA, EFORT, AAHKS, ORS, NASS, and AOSSM) from February 2021 to November 2021 were analyzed. Meeting information was retrieved from the conference agendas, and details of chairs and speakers were obtained from Linkedin, Doximity, CPSO, personal websites, and Web of Science. Primary outcomes included: one) percentage of male faculty in all included sessions and two) overall percentage of manels. Secondary outcomes included one) percentage of male speakers and chairs in all included sessions, two) overall percentage of male-chair and male-speaker only sessions. Comparisons for outcomes were made between conferences and session topics (adult reconstruction hip, adult reconstruction knee, practice management/rehabilitation, trauma, sports, general, pediatrics, upper extremity, musculoskeletal oncology, foot and ankle, spine, and miscellaneous). Mean number of sessions for male and female were compared after being stratified into quartiles based on publications, sum of times cited, and H-indexes. Data was analyzed with non-parametric analysis, chi-square tests, or independent samples t-tests using SPSS version 28.0.0.0 with a p-value of < 0 .05 being considered statistically significant.

Of 193 included sessions, 121 (62.3%) were manels and the mean percentage of included faculty that was male was 88.9% Apart from the topics of practice management/rehabilitation and musculoskeletal oncology, male representation was very high. Additionally, most included conferences had an extremely high percentage of male representation apart from meetings hosted by the COA and ORS. Non-manel sessions had a greater mean number of chairs (p=0.006), speakers (p < 0 .001), and faculty (p < 0 .001) than manel sessions. Of 1080 total included faculty members, 960 (88.9%) were male. Male faculty were more likely to be Orthopedic surgeons than female faculty (p < 0 .001) while also more likely to hold academic rank as a professor. Mean number of sessions between male and female faculty within their respective quartiles of H-indexes, sum of times cited, and number of publications did not reach statistical significance. Mean years of practice between male and female faculty was also not significantly different.

There is a high prevalence of manels and an overall lack of female representation in Orthopedic meetings. Orthopedic associations should aim to make efforts to increase gender equity in future meetings.

Tibial shaft fractures have a high incidence of delayed and non-union, often requiring multiple procedures. Pulsed electromagnetic field (PEMF) stimulation is a safe and effective treatment for tibial non union but little is known about the efficacy of PEMF in preventing non-union in acute fractures.

Between August 2005 and December 2008, eligible patients presenting at six major metropolitan hospitals with acute tibial shaft fractures (AO classification 4-2) were included. Participants were randomised by an independent allocation centre to identical active or inactive PEMF devices, both prescribed to be worn ten hours daily for twelve weeks. Baseline data were collected, and patients and surgeons were surveyed serially via post and/or phone at three, six and twelve months. Participants, data collectors and data analysts were blinded. The main outcome was any surgical intervention for delayed/non union.

Data from 150 patients (76 active and 74 inactive) were available for analysis (12 month follow up 78%). There was no between-group difference in age, gender, mechanism of injury, open grade, smoking status, or compliance with the device (hours of use). Overall compliance was moderate (5.7 hours daily use). Fifteen of 76 (20%) of active device patients required surgery for delayed/non-union vs. 8 of 74 (11%) in the placebo group; odds ratio of surgery=2.03, p=0.13, 95% CI 0.80 to 5.12. An intention to treat analysis adjusted for open grade and hours the device was used showed an odds ratio of requiring surgery of 1.78 (p=0.24, 95% CI 0.68 to 4.64). A sub-group analysis of 80 compliant patients (defined a priori as a minimum average of six hours daily use) was performed. Nine of 35 (26%) patients with an active device required surgery for delayed/non-union vs. 3 of 45 (7%) in the placebo group; odds ratio of surgery=7.60 (p=0.017, 95% CI 1.43 to 40.24).

Based on these unexpected initial results, PEMF stimulation does not prevent revision surgery for delayed/non-union in acute fractures of the tibial shaft.

This study aims to explore the trend in spine fusion surgery in Australia over the past 10 years and to explore the possible influence of health insurance status (private versus public) on the rate of surgery.

Data pertaining to the rate of lumbar spine fusion from 1997 to 2006 were collected. Data on publicly performed procedures in NSW were obtained from Inpatient Statistics Collection of NSW Health, and data on privately performed procedures were obtained from Medicare Australia Statistics. Population data was obtained from the Australian Bureau of Statistics. Data on total hip and total knee arthroplasties performed were collected to provide a comparator. Health insurance coverage was also investigated to control for insurance status, this data was obtained from the Private Health Insurance Administration Council.

There has been a slowly declining trend in the number of publicly performed spinal fusion procedures over the past 10 years, falling by 63% from 1997 to 2006 in NSW. In comparison, privately performed spinal fusion procedures have increased by 166% over the same 10 year period. Compared to spine fusion, the rates of total hip and total knee replacement procedures in the public sector of NSW have fallen by smaller proportions (58.9%% and 42.1%, respectively) over the same 10 year period. The increase in privately performed joint replacements has been less than that seen for spine fusion, with increases of 120% and 74%% for knee arthroplasties and hip arthroplasties, respectively.

In 2006, spine fusion surgery was 10.8 times more likely to be done in the private sector than in the public sector, compared to corresponding figures of 4.2 times and 3.0 times for knee replacement and hip replacement, respectively.

Our study has demonstrated that there is a disproportionately high rate of spine fusion procedures performed in the private sector. Possible explanations for this difference include: over servicing in the private sector, under servicing in the public sector, differences in medical referral patterns, surgeon and patient preferences, and financial incentives.

Patient satisfaction has only recently gained attention as an outcome measure in orthopaedics, where it has been reported for joint replacement surgery. Little has been published regarding predictors of patient satisfaction in orthopaedic trauma. This study aims to explore the predictors of patient satisfaction, and of surgeon satisfaction, after orthopaedic trauma.

Adult patients admitted to hospital with fractures after motor vehicle trauma were surveyed on admission, and at six months. Demographic, injury, socio-economic and compensation-related factors were measured. The two outcomes were satisfaction with progress of the injury, and satisfaction with recovery. The treating surgeons were also surveyed at six months to determine surgeon satisfaction with progress, and recovery (using the same questions), and the presence or absence of fracture union and any complications. Multivariate analysis was used to determine significant predictors of satisfaction for both groups, and satisfaction rates were compared between surgeons and patients using multivariable analysis.

Of 306 patients recruited, 232 (75.8%) returned completed questionnaires, but only 141 (46.1%) surgeons responded. Patients rated their satisfaction with progress and recovery as 74.6% and 44.4%, respectively, whereas surgeon-rated satisfaction with progress and recovery was 88.0% and 66.7%, respectively (p< 0.0001). Significant predictors of patient dissatisfaction were: blaming others for the injury, being female, and using a lawyer. Patient-rated outcome was not significantly associated with objective injury or treatment factors. The only significant predictor of surgeon dissatisfaction was fracture non-union.

Orthopaedic surgeons overestimated the progress of the injury and the level of recovery compared to patients’ own ratings. Surgeons’ ratings are influenced by objective, treatment-related factors, whereas patients’ ratings were not. Measures of outcome commonly used b y orthopaedic surgeons, such as fracture union, do not predict patient satisfaction.
