ABSTRACT

INTRODUCTION: The indications for reduction and fixation of the posterior malleolus component of rotational ankle fractures have been controversial for nearly a century. This study aims to identify the historical basis for surgical intervention and trace trends in management strategies over time. METHODS: In March 2023, a systematic review of full-text, English-language articles providing indications for surgical fixation of the posterior malleolus component of rotational ankle fractures was performed. Articles underwent title and abstract screening before undergoing full-text review. RESULTS: Historical indications for surgical fixation were size-dependent, with fractures comprising 25 % to 33 % of the plafond recommended for internal fixation. Modern studies suggest that nonoperative management of posterior malleolus fractures below this threshold results in residual malreduction of the articular surface, syndesmotic instability, and an increased need for independent fixation of the syndesmosis. CONCLUSIONS: Size-based indications for posterior malleolus fracture fixation are based on Level V evidence from small retrospective case series published nearly one century ago and should be retired. While the size of the posterior malleolus component cannot be ignored, additional factors like fracture morphology and location within the plafond should guide modern surgical indications. Contemporary studies indicate that reduction and fixation of small posterior malleolus fractures (comprising less than 25 % of the articular surface) are associated with improved articular reductions, tibiotalar contact pressures, syndesmotic stability with decreased need for independent fixation of the syndesmosis, and superior postoperative outcomes.

ABSTRACT

BACKGROUND: Early mobilization following ankle fracture open reduction and internal fixation (ORIF) improves long-term patient functionality. Because of this, numerous resources have been spent to increase patient adherence to post-operative mobilization, with range of motion (ROM) measurements generally considered an important outcome in patient recovery. In this study we investigated how ankle ROM correlates to patient function, self-sufficiency in performing activities of daily living (ADLs), and pain in the early post-operative period. METHODS: This was a prospective, observational study on patients undergoing ORIF of ankle fractures. We collected patient reported outcome measures (PROMs) and ROM measurements at the 2-week, 6-week, 12-week, and 6 month post-operative visit. We collected three PROMs: pain intensity (VAS), pain self-efficacy questionnaire (PSEQ-2), and foot and ankle ability measurement (FAAM). ROM of the ankle was measured by goniometer. ANOVA and post-hoc Tukey tests were used to examine statistical differences in PROMs over time. Pearson correlation tests were used to examine the association between ROM and PROMs. RESULTS: One-hundred and twenty-three participants enrolled in this study in the perioperative period. Pain intensity was higher at enrollment compared to week 6 (post-hoc p = 0.006), after which pain intensity did not differ significantly. FAAM scores for activities or daily living (ADL) were increased at all study visits compared to enrollment (post-hoc p < 0.001). FAAM-Sports scores were higher compared to enrollment at the week 12 and 6 month visits (post-hoc p < 0.001). No significant improvements in goniometer measurements were noted across any timepoints. There were no significant correlations between ROM and PROMs at any of the study visits. CONCLUSION: In our cohort of patients, there was no correlation between ROM and patient pain, self-efficacy or functionality in the early post-operative period following ankle ORIF. The lack of correlation between PROMs and ROM indicates that ROM may be both a poor indicator of patient improvement for physicians to guide post-operative treatment as well as a poor motivator for patient adherence to post-operative exercises. In the future, it is important to study reliable outcome measures in early recovery that can be utilized to track patient recovery from ankle ORIF.

ABSTRACT

BACKGROUND: The United States is increasingly diverse and there are many benefits to an equally diverse physician workforce. Despite this, the percentage of under-represented minorities in orthopaedic surgery has remained stagnant. The purpose of this study was to describe the characteristics underrepresented minorities pursuing orthopaedic surgery value most when evaluating residency programs. METHODS: The contact information of current underrepresented minority orthopaedic surgery residents were obtained through professional society databases, residency program coordinators and residency program websites. Individuals were sent a survey through which they evaluated the importance of a variety of program characteristics. RESULTS: The most influential program characteristics were resident happiness and camaraderie, program reputation, geographic location, and relationships between residents and attendings. The least influential characteristics were sub-internship scholarship opportunities for minorities, program affiliation with diversity organizations, word of mouth from others, number of fellows, and centralized training sites. CONCLUSIONS: There is a need to diversify the field of orthopaedic surgery, which begins by selecting more diverse trainees. This study demonstrates that underrepresented applicants are most influenced by many of the same characteristics as their well-represented peers. However, diversity-related factors still play an important role in the decision-making process. Many residents highlighted the impact microaggressions and mistreatment played in their residency experience, emphasizing the need for residency programs to focus not only on recruitment, but also on the successes and retention of their residents. Only once this is done will the field of orthopaedic surgery find sustained improvement in its diversification efforts.

ABSTRACT

INTRODUCTION: Supine sleep position is associated with stillbirth, likely secondary to inferior vena cava compression, and a reduction in cardiac output (CO) and uteroplacental perfusion. Evidence for the effects of prone position in pregnancy is less clear. This study aimed to determine the effect maternal prone position on maternal haemodynamics and fetal heart rate, compared with left lateral position. METHODS: Twenty-one women >28 weeks' gestation underwent non-invasive CO monitoring (Cheetah) every 5 minutes and continuous fetal heart rate monitoring (MONICA) in left lateral (20 minutes), prone (30 minutes), followed by left lateral (20 minutes). Anxiety and comfort were assessed by questionnaires. Regression analyses (adjusted for time) compared variables between positions. The information derived from the primary study was used in an existing mathematical model of maternal circulation in pregnancy, to determine whether occlusion of the inferior vena cava could account for the observed effects. In addition, a scoping review was performed to identify reported clinical, haemodynamic and fetal effects of maternal prone position; studies were included if they reported clinical outcomes or effects or maternal prone position in pregnancy. Study records were grouped by publication type for ease of data synthesis and critical analysis. Meta-analysis was performed where there were sufficient studies. RESULTS: Maternal blood pressure (BP) and total vascular resistance (TVR) were increased in prone (sBP 109 vs 104 mmHg, p = 0.03; dBP 74 vs 67 mmHg, p = 0.003; TVR 1302 vs 1075 dyne.s-1cm-5, p = 0.03). CO was reduced in prone (5.7 vs 7.1 mL/minute, p = 0.003). Fetal heart rate, variability and decelerations were unaltered. However, fetal accelerations were less common in prone position (86% vs 95%, p = 0.03). Anxiety was reduced after the procedure, compared to beforehand (p = 0.002), despite a marginal decline in comfort (p = 0.04).The model predicted that if occlusion of the inferior vena cava occurred, the sBP, dBP and CO would generally decrease. However, the TVR remained relatively consistent, which implies that the MAP and CO decrease at a similar rate when occlusion occurs. The scoping review found that maternal and fetal outcomes from 47 included case reports of prone positioning during pregnancy were generally favourable. Meta-analysis of three prospective studies investigating maternal haemodynamic effects of prone position found an increase in sBP and maternal heart rate, but no effect on respiratory rate, oxygen saturation or baseline fetal heart rate (though there was significant heterogeneity between studies). CONCLUSION: Prone position was associated with a reduction in CO but an uncertain effect on fetal wellbeing. The decline in CO may be due to caval compression, as supported by the computational model. Further work is needed to optimise the safety of prone positioning in pregnancy. TRIAL REGISTRATION: This trial was registered at clinicaltrials.gov (NCT04586283).

ABSTRACT

BACKGROUND: Erectile dysfunction (ED) is a prevalent side effect of prostate cancer treatment. We hypothesized that the previously reported rates of ED may have improved with the advent of modern technology. The purpose of this project was to evaluate modern external beam radiotherapy and brachytherapy techniques to determine the incidence of radiotherapy (RT) induced ED. METHODS: A systematic review of the literature published between January 2002 and December 2018 was performed to obtain patient reported rates of ED after definitive external beam radiotherapy, ultrafractionated stereotactic radiotherapy, and brachytherapy (BT) to the prostate in men who were potent prior to RT. Univariate and multivariate analyses of radiation dose, treatment strategy, and length of follow-up were analyzed to ascertain their relationship with RT-induced ED. RESULTS: Of 890 articles reviewed, 24 met inclusion criteria, providing data from 2714 patients. Diminished erectile function status post RT was common and similar across all studies. The median increase in men reporting ED was 17%, 26%, 23%, and 23%, 3DCRT, IMRT, low dose rate BT, and SBRT, respectively, at 2-year median follow-up. CONCLUSION: ED is a common side effect of RT. Risk of post-RT ED is similar for both LDR brachytherapy and external beam RT with advanced prostate targeting and penile-bulb sparing techniques utilized in modern RT techniques.

ABSTRACT

BACKGROUND: Erectile dysfunction (ED) is the most common side effect of prostate radiotherapy (RT), but reported rates over time and across modalities have varied widely. AIM: To evaluate the published literature between 2002 and 2018 for high quality data utilizing prospectively gathered patient-reported ED, and to summarize the challenges in reporting of RT-induced ED (RIED). METHODS: A PubMed search and literature review was performed to identify articles describing rates of ED before and after definitive external beam RT or brachytherapy without androgen deprivation. OUTCOMES: Patient-reported ED, patient and treatment variables, and study follow-up constituted the main outcomes of this study. RESULTS: 24 articles were identified, reporting RIED rates between 17% and 90%. Variables contributing to this range included patient, treatment, and study characteristics known to impact ED reporting. CLINICAL IMPLICATIONS: For future studies, we recommend the use of validated patient-reported questionnaires and reporting of baseline function and comorbidities, RT type and dose, and use of androgen deprivation therapy and erectile aids at the time of ED measurement. With sufficient follow-up to understand the late nature of RIED, these recommendations will improve comparison of results between studies and the applicability of results to patients undergoing pretreatment counseling regarding the risks of RIED. STRENGTHS & LIMITATIONS: The literature search and formulation of results were based on a broad understanding of the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines and the literature, but because of the focus on data reporting, a comprehensive systematic review of all RIED literature was not performed. CONCLUSION: Reported rates of ED after RT vary widely due to differences in patients' baseline reported erectile function, age, comorbidities, and characteristics of the treatment delivered. The methodology of ED measurement has significant impact on the applicability and comparability of results to other studies and clinical practice. Nukala V, Incrocci L, Hunt AA, et al.

ABSTRACT

PURPOSE: Previous epidemiological and cost studies of fungal meningitis have largely focused on single pathogens, leading to a poor understanding of the disease in general. We studied the largest and most diverse group of fungal meningitis patients to date, over the longest follow-up period, to examine the broad impact on resource utilization within the United States. METHODOLOGY: The Truven Health Analytics MarketScan database was used to identify patients with a fungal meningitis diagnosis in the United States between 2000 and 2012. Patients with a primary diagnosis of cryptococcal, Coccidioides, Histoplasma, or Candida meningitis were included in the analysis. Data concerning healthcare resource utilization, prevalence and length of stay were collected for up to 5 years following the original diagnosis. RESULTS: Cryptococcal meningitis was the most prevalent type of fungal meningitis (70.1 % of cases over the duration of the study), followed by coccidioidomycosis (16.4 %), histoplasmosis (6.0 %) and candidiasis (7.6 %). Cryptococcal meningitis and candidiasis patients accrued the largest average charges ($103 236 and $103 803, respectively) and spent the most time in the hospital on average (70.6 and 79 days). Coccidioidomycosis and histoplasmosis patients also accrued substantial charges and time in the hospital ($82 439, 48.1 days; $78 609, 49.8 days, respectively). CONCLUSION: Our study characterizes the largest longitudinal cohort of fungal meningitis in the United States. Importantly, the health economic impact and long-term morbidity from these infections are quantified and reviewed. The healthcare resource utilization of fungal meningitis patients in the United States is substantial.
