Transverse patella fracture fixation: A cadaveric biomechanical comparison of cannulated screws and anterior tension band versus low-profile, multiplanar mesh plating.

INTRODUCTION: Multiplanar mesh plating of patella fractures has become more popular in recent years. It was the goal of this study to compare the biomechanical stability of cannulated screw with anterior tension band to multiplanar mesh plating for fixation of transverse patella fractures in cadaver specimens. MATERIALS AND METHODS: Eight matched pairs of fresh frozen cadaveric knees were obtained and soft tissues dissected leaving the extensor mechanism, joint capsule, and retinaculum intact. Transverse fractures were created at the mid-portion of the patella. For each pair, one specimen was repaired using cannulated screws with anterior tension band, and the second was repaired using multiplanar mesh plating. Each specimen underwent cyclic extension loading with loads increasing by 1.1 kg after every 50 cycles. Interfragmentary displacement was measured at the end of each interval at both 5° and 45° of knee flexion angle, with fixation failure defined by >2 mm displacement. RESULTS: The specimens fixed with multiplanar mesh plating survived more cycles and higher loads than the specimens fixed with cannulated screws with anterior tension band (p = 0.011 comparing survival plots). After 150 cycles of extension loading, 3 of 8 of the specimens fixed with screws/tension band had failed, whereas none of the mesh plated specimens had failed. After 400 cycles, 7 of 8 of the screws/tension band had failed, whereas half of the mesh plated specimens had failed. CONCLUSIONS: While a more technically challenging and expensive technique, mesh plating for patella fractures appears to offer greater durability than traditional cannulated screw with tension banding.

Training Program Factors Most Important to Women When Selecting an Otolaryngology Residency.

OBJECTIVES: The aim of the study was to determine factors that female resident physicians find most influential when choosing an otolaryngology residency program. METHODS: A three-part survey was sent to current female otolaryngology residents via email evaluating the importance of 19 characteristics impacting program choice. The 19 factors were scored from 1 (least important) to 5 (most important). The participants also ranked their personal top five most influential factors. Data were analyzed using descriptive statistics. RESULTS: One-hundred and fifty of 339 contacted residents participated. Most were aged 30-39 (63%), white (70%), and married (43%). Eighty-five percent had no children, and 52% did not plan to have children during residency. The highest scoring factors derived from Likert scale ratings included resident camaraderie (4.5 ± 0.8), resident happiness (4.4 ± 0.8), and case variety/number (4.4 ± 0.8). The lowest scoring factors were number of fellows (2.9 ± 1.1), attitudes toward maternity leave (2.7 ± 1.3), and maternity leave policies (2.4 ± 1.2). The top five most influential factors and the percentage selecting this were resident camaraderie (57%), resident happiness (57%), academic reputation (51%), case variety/number (47%), and early surgical/clinical experience (44%). Gender-specific factors were infrequently selected. However, 51 (34%) ranked at least one gender-specific factor within their top five list. CONCLUSION: Non-gender-related factors, like resident camaraderie and surgical experiences, were most valued by women. Conversely, gender-specific factors were less critical and infrequently ranked. Ninety-nine residents (64%) rated exclusively gender-neutral characteristics in their top five list of most influential factors. Our data offer insight into program characteristics most important to female otolaryngology residents, which may assist residency programs hoping to match female applicants.

Urology Match: Important Factors Women Consider When Choosing a Residency Training Program.

OBJECTIVE: To determine factors that women urology resident physicians rate as most influential when selecting residency programs. METHODS: Surveys were emailed to female urology residents during the 2021-2022 academic year. Residents scored 19 factors influencing residency program choice from 1 "least" to 5 "most" important and ranked their top 5 most influential factors. Data were analyzed via descriptive statistics and quantile regression. RESULTS: One hundred thirty-six (37%) of 367 female urology residents who received the survey participated. Eighty-two percent had no children and 57% did not plan to have children during residency. The three highest scoring factors derived from Likert scale ratings were resident camaraderie (4.6 ±â€¯0.5 [mean ±â€¯SD]), resident happiness (4.6 ±â€¯0.6), and case variety/number (4.4 ±â€¯0.8). As a whole, the lowest scoring characteristics were attitudes toward maternity leave (2.6 ±â€¯1.2) and maternity leave policies (2.5 ±â€¯1.2). Married residents were more likely than those who were single and engaged/in a committed relationship to rank attitudes and policies toward maternity leave as more important (3 vs 2 vs 2, P <.0001). Residents with children were more likely than those without children to rank maternity leave policies as more important (3 vs 2, P <.0001). CONCLUSION: As a whole, women urology residents prioritized non-gender-related factors. However, gender-specific factors were rated highly by married residents and those with children or planning to have children. Urology training programs may use these results to highlight desirable characteristics to aid recruitment of female residents.

To Use or Not Use Intraoperative Neuromonitoring: Utilization of Neuromonitoring During Spine Surgeries and Associated Conflicts of Interest, a Cross-Sectional Survey Study.

INTRODUCTION: There are no universal guidelines that dictate the indications for the use of intraoperative neuromonitoring (IONM) in spine surgery resulting in its variable use. The choice to use IONM has been both cited in malpractice lawsuits and insurance claims, but no data exist regarding surgeons' rationale for making this choice. The goal of this study was to assess (1) the use of certain IONM modalities during common spine surgeries, (2) surgeons' rationale for use of IONM, and (3) IONM practices and potential conflicts of interest associated with its use. METHODS: Respondents were asked to select each IONM modality they used during 20 different surgical scenarios within the spine followed by rating the importance of several reasons when selecting to use IONM. Finally, the occurrence of conflicts of interest, out-of-network billing, and cost were assessed. RESULTS: Approximately one-half (47%) of respondents who perform anterior cervical diskectomy and fusion/total disk arthroplasty for radiculopathy use IONM, opposed to 76% for myelopathy. The presence of cord compression and/or neurologic symptoms increased IONM use by approximately 30% during trauma cases. Medicolegal was the reason of highest importance when choosing to use IONM (7.4 ± 2.9; mean ± SD), followed by surgeon reassurance (6.2 ± 2.7; P < 0.0001 versus medicolegal) and belief it affects patient outcomes (5.2 ± 3.0; P = 0.004 versus reassurance). CONCLUSIONS: Although there is increasing use of IONM, this has not translated to an absolute requirement for every spine surgery. Surgeons are faced with opposing influences of the medicolegal system and insurance payers. Future guidelines on using IONM should not be absolute, but rather should consider the risks of each procedure, along with how patients and surgeons value these risks, in addition to the costs. The findings of this study should help to serve as a guide to surgeons, payers, and courts as contemporary, common practices for the use of IONM during spinal surgical scenarios.

Charting the course from abstract to published article.

OBJECTIVE: Abstracts act as short, efficient sources of new information. This intentional brevity potentially diminishes scientific reliability of described findings. The authors' objective was to 1) determine the proportion of abstracts submitted to the American Association of Neurological Surgeons (AANS) annual meeting that subsequently are published in peer-reviewed journals, 2) assess AANS abstract publications for publication bias, and 3) assess AANS abstract publications for differing results. METHODS: The authors screened all abstracts from the annual 2012 AANS meeting and identified their corresponding full-text publication, if applicable, by searching PubMed/MEDLINE. The abstract and subsequent publication were analyzed for result type (positive or negative) and differences in results. RESULTS: Overall, 49.3% of abstracts were published as papers. Many (18.1%) of these published papers differed in message from their original abstract. Publication bias exists, with positive abstracts being 40% more likely to be published than negative abstracts. The top journals in which the full-text articles were published were Journal of Neurosurgery (13.1%), Neurosurgery (7.3%), and World Neurosurgery (5.4%). CONCLUSIONS: Here, the authors demonstrate that alone, abstracts are not reliable sources of information. Many abstracts ultimately remain unpublished; therefore, they do not attain a level of scientific scrutiny that merits alteration of clinical care. Furthermore, many that are published have differing results or conclusions. In addition, positive publication bias exists, as positive abstracts are more likely to be published than negative abstracts.

Does Publication History Predict Future Publication Output in Orthopaedics?

Background The number of publications is widely used as a measure of academic productivity in the field of orthopaedics. How "productive" a physician is has a great influence on consideration for employment, compensation, and promotions. Predictors of potential high-output researchers would be of value to the orthopaedic department and university leadership for new faculty evaluation. Methods The study population included orthopaedic faculty from the top 10 orthopaedic institutions in the United States. Their names and the number of publications at each point in their training (medical school, residency, and fellowship) and early career (first five and 10 years following fellowship) along with a total number of publications to date were collected by using PubMed. Results Strong correlations were seen between publications during total training and publications output in the first five years following fellowship (rs =0.717, P<0.0001). However, no significant correlations were found comparing publications during each stage of training and the first 10 years following fellowship. A moderate positive correlation was found when comparing publications during medical school and residency output (rs =0.401, P<0.0001). Conclusions The data presented here may be utilized by department chairs during the evaluation of faculty and candidates to not interpret the number of publications during training and early career as a gauge of research interest and potential for future publications. Program directors may also use the only moderate correlation between publications in medical school and residency when evaluating applications as support of a more holistic review of applicants to determine research interest.

Natural History of 321 Flatfoot Reconstructions in Adult Acquired Flatfoot Deformity Over a 14-Year Period.

The purpose of this study was to report the natural history, demographics, and mechanisms of requirement for additional surgery in patients undergoing flatfoot reconstruction for adult acquired flatfoot. A total of 321 consecutive patients undergoing flatfoot reconstruction over a 14-year period were included (2002-2016). All procedures were performed by a senior orthopaedic foot and ankle surgeon at our institution. Demographic data, operative reports, clinic notes, and radiographs were available for review. Statistical analysis included calculation of relative risk (RR) ratios. The majority of patients were female (83.2%,) and most patients were overweight with a body mass index greater than 25 kg/m2 (56.4%). Patient comorbidities included diabetes (13.7%) and rheumatoid arthritis (3.7%). Additional surgery was required for 54 patients (16.8%). The most common reasons for additional surgery were the following: painful calcaneal hardware (57.4%), conversion to triple arthrodesis (16.7%), and wound healing complications (9.1%). An increased risk of need for additional surgery was associated with female gender (RR = 3.4; P = .0005), smoking status (RR = 1.9; P = .0081), and age (<60 years of age; RR = 1.8; P = .042). Although retrospective, the results provide insight into the natural history of this procedure. Clinicians may use these data to appropriately counsel patients who are at increased risk of requirement for additional surgery, such as smokers, women, and patients <60 years old, regarding treatment options.Levels of Evidence: Level IV.

Factors in Orthopaedic Residency Decision-making for Female Applicants: A Cross-sectional Study.

BACKGROUND: Orthopaedics continues to remain the medical specialty with the lowest sex diversity in the United States. Orthopaedic residency programs are highly motivated to attract the best female candidates in an effort to improve their program diversity, but no studies currently exist that examine the factors of highest importance to female applicants for orthopaedic residency selection. METHODS: A two-part survey was sent to female orthopaedic residents by e-mails available in the American Academy of Orthopaedic Surgery directory, residency program coordinators, Doximity, and institutional websites. The survey included 17 characteristics of residency programs that participants were asked to score for importance and then asked to rank their top five most influential factors when selecting an orthopaedic surgery residency. RESULTS: The most important factors included camaraderie among residents, happiness of current residents, variety/number of cases, fellowship placement, and early surgical/clinical experience, respectively. The least important factors included sex diversity of faculty and residents, number of female residents, concurrent fellows, number of female faculty geographic location near spouse, and finally, attitudes toward maternity leave. DISCUSSION: These data support the notion that efforts by orthopaedic residency programs to improve desirability for female applicants should focus on highlighting some of the more universal, nonsex-related factors such as the happiness and camaraderie among residents and the anticipated clinical experiences. This is opposed to showcasing features, such as maternity leave and number of current female faculty or residents, which would seemingly appeal to female applicants.

Factors in Residency Decision Making for Female Neurosurgery Applicants.

BACKGROUND: Neurosurgery remains a specialty with one of the largest gender gaps in the United States. Neurosurgery residency programs are highly motivated to attract the best female candidates in an effort to improve their program diversity, but no studies currently exist that examine the factors of highest importance to female applicants for neurosurgery residency selection. The purpose of this study was to determine factors that female neurosurgery residents used when selecting their residency. METHODS: A 2-part survey was sent to female neurosurgical residents by e-mails collected from the American Association of Neurological Surgeons directory and residency program websites. The survey asked participants to score 17 characteristics of residency programs in terms of importance and then asked them to rank their top 5 most influential factors when selecting a neurosurgery residency. RESULTS: The most important factors included variety/number of cases, camaraderie and happiness of current residents, early surgical/clinical experience, and academic reputation. The least important factors included gender diversity of faculty and residents, number of female residents, number of female faculty, and attitudes toward maternity leave. CONCLUSIONS: Efforts to increase female applicants in neurosurgery residency programs should focus on highlighting some more universal, non-gender-related factors, such as happiness and camaraderie among residents and anticipated clinical experiences, as opposed to showcasing features that would seemingly appeal to female applicants, such as maternity leave and number of current female faculty or residents.

Authorship and study characteristic trends in spine publications from years 2004 to 2017.

BACKGROUND: The goal of this study was to analyze the trends in authorship and study characteristics in Spine using two overlapping ten-year time periods: 2004-2014 and 2007-2017. To our knowledge, no other literature reports study characteristics and authorship in the same time period for spine that would allow for the assessment of confounding factors of trends. METHODS: Authorship and study characteristic data was collected from all scientific manuscripts published in Spine during the years of 2004, 2007, 2014, and 2017. Basic statistics and Kruskal-Wallis test were used to analyze the data. RESULTS: We found a significant increase in total number of authors (P<0.0001) without discrepancy of unequivocal increases in author degree type: MD/Equivalent (P≤0.0001), PhD/Doctorate (P=0.0017), Masters (P=0.0015), and Bachelors (P≤0.0001). We observed an increase in industry authorship (P≤0.0001), but without a significant increase in industry funding during the same time span. Increases in administration database studies (P≤0.0001) and economic/value studies (P≤0.0001) were also noted. A significant change in percentage of articles with trauma pathology (decrease, P<0.0001) and deformity (increase, P=0.0002) occurred. The number of multi-institutional studies increased (P≤0.0001), while no change in the number of multi-disciplinary studies. CONCLUSIONS: Increases in author number for spine articles over time are a result of a general increase in authors in all degree types, not just non-doctorate degrees. This may be potentially influenced by the increase in multi-institutional studies. From 2004-2017, higher percentages of articles focus on economics. An increase in industry authorship without a corresponding increase in funding suggests industry's more 'hands-on' approach to publication results from their funded studies.

Septic Arthritis of the Hip and Enterocutaneous Fistula Formation After Hip Arthroscopy: A Case Report of Psoas Abscess Misdiagnosed as Labral Pathology.

CASE: We describe a case of septic hip arthritis and enterocutaneous fistula formation caused by the seeding of a hip joint during hip arthroscopy performed in the setting of a psoas abscess. Treatment consisted of multiple debridements and femoral head resection with subsequent total hip arthroplasty. CONCLUSIONS: This case highlights the importance of a thorough history, physical examination, and assessment of available imaging before proceeding to surgery, even when the procedure is one considered to have minimal risks, such as arthroscopy.
