The predominant insertion of the ischiofemoral ligament is a merging to the iliofemoral ligament as demonstrated on magnetic resonance arthrogram studies.

BACKGROUND: The capsular ligaments at the hip joint work in synchrony with the acetabulum and femoral head for articular stability. There is a lack of understanding about ischiofemoral ligament (ISFL) anatomy and function. PURPOSE: To assess the insertion of the ISFL in non-arthritic adult hips. MATERIAL AND METHODS: A retrospective analysis was performed in 72 patients who underwent magnetic resonance arthrogram (MRA) for the assessment of hip pain. The distribution of the ISFL components, the thickness, and the insertion site were assessed by concomitantly using the axial oblique, coronal, and sagittal MRA images. RESULTS: Two insertions of the ISFL anterior to the center of the femoral head were identified in 71 (99%) hips: (i) predominant anterior merging with the iliofemoral ligament as continuation of zona orbicularis, observed in all hips; and (ii) anterolateral junction of femoral neck and greater trochanter. Two ISFL parts (proximal and distal) were identified in 70 (97%) of the 72 studied hips. The proximal part was always thinner (mean 2.6 ± 0.7 mm) and originated from the ischium at the acetabular rim. The distal part was a continuation of the zona orbicularis, and the mean thickness was 6.7 ± 1.6 mm. Both parts merged as they coursed over the superior portion of the femoral head. CONCLUSION: The predominant insertion of the ischiofemoral ligament is a merging to the iliofemoral ligament anteriorly. Surgical procedures such as hip arthroscopy involving the ISFL will affect the function of the iliofemoral ligament, and vice versa.

Success of staged revision reverse total shoulder arthroplasty in eradication of periprosthetic joint infection.

INTRODUCTION: Management of periprosthetic joint infection (PJI) in shoulder arthroplasty remains a challenge, with no established gold standard treatment. This study presents the unique experience of a high-volume single-surgeon, single-institution approach on staged revision reverse total shoulder arthroplasty (RTSA) for infection. The authors theorize that staged revision RTSA is an effective treatment for PJI. MATERIALS AND METHODS: Between 2013 and 2018, 38 patients underwent a staged RTSA for treatment of PJI. Patient histories were collected and classified using Cierny-Mader classification. Infection workup for all patients included radiographs, laboratory indices, and computed tomographic aspiration arthrogram. PJI was identified based on high clinical and radiographic suspicion, elevated serologic markers, and/or aspirate culture results per 2018 International Consensus Meeting Shoulder guidelines on Orthopedic Infections. All patients underwent first stage with implant removal, irrigation and débridement, and antibiotic spacer placement. Next, intravenous antibiotics were administered by infectious disease consultants for a minimum of 6 weeks. Infection workup was then repeated and, if normalized, final-stage revision commenced with antibiotic spacer removal and revision to RTSA. If indices were persistently abnormal, an additional stage of débridement and spacer placement procedure was performed. Treatment failure was defined as recurrent periprosthetic infection after final prosthesis implantation or persistently elevated indices despite adequate débridement and spacer placement. RESULTS: Mean age of the cohort was 68 (standard deviation [SD] 8.9) years and mean follow-up was 33 (SD 14) months with 34 Cierny-Mader C hosts and 4 B hosts. Patients underwent a mean of 2 (SD 1.1) previous surgeries. The staged revision protocol was successful in 34 (89.5%) patients for management of PJI. Four patients (10.5%) were considered failures with recurrent infections at a mean of 13 months (range 2-26 months) after the final RTSA implantation and underwent repeat staged revisions. Of the 34 patients who had successful infection eradication, 31 had 2-stage treatment and 3 had to undergo 3 stages. There were no treatment-associated mortalities and 10 major complications (26%), including permanent neuropathy, instability, and periprosthetic fractures. The most common cultured microorganism was Cutibacterium acnes (18%), with no polymicrobial infections detected. DISCUSSION: Although there are multiple treatment options for PJI management, staged revision remains an effective means of treatment. Although there were several patients who required an additional stage of treatment, and a significant complication rate, staged revision RTSA proved successful in the ultimate eradication of the PJI.

Racial and Ethnic Disparities in Providing Guideline-Concordant Care After Hip Fracture Surgery.

Importance: Institutions have adopted protocol-driven standardized hip fracture programs (SHFPs). However, concerns persist regarding bias in adherence to guideline-concordant care leading to disparities in implementing high-quality care for patients recovering from surgery for hip fracture. Objective: To assess disparities in the implementation of guideline-concordant care for patients after hip fracture surgery in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Targeted Hip Fracture (THF) Database. Design, Setting, and Participants: This cross-sectional study was conducted using the ACS-NSQIP THF database from 2016 to 2021 for patients aged 65 years and older with hip fractures undergoing surgical fixation. Care outcomes of racial and ethnic minority patients (including American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or Pacific Islander, or multiple races and Hispanic ethnicity) were compared with non-Hispanic White patients via risk difference, stratified by care institution SHFP status. Modified Poisson regression was used to measure interactions. Statistical analysis was performed from November 2022 to June 2024. Main Outcomes and Measures: The primary outcomes of interest encompassed weight-bearing as tolerated (WBAT) on postoperative day 1 (POD1), venous thromboembolism (VTE) prophylaxis, bone-protective medication, and the presence of SHFP at the institution. Results: Among 62 194 patients (mean [SD] age, 82.4 [7.3] years; 43 356 [69.7%] female) who met inclusion criteria and after multiple imputation, 11.2% (95% CI, 10.8%-11.5%) were racial and ethnic minority patients, 3.3% (95% CI, 3.1%-3.4%) were Hispanic patients, and 92.0% (95% CI, 91.7%-92.2%) were White. Receiving care at an institution with an SHFP was associated with improved likelihood of receiving guideline-concordant care for all patients to varying degrees across care outcomes. SHFP was associated with higher probability of being WBAT-POD1 (risk difference for racial and ethnic minority patients, 0.030 [95% CI, 0.004-0.056]; risk difference for non-Hispanic White patients, 0.037 [95% CI, 0.029-0.45]) and being prescribed VTE prophylaxis (risk difference for racial and ethnic minority patients, 0.066 [95% CI, 0.040-0.093]; risk difference for non-Hispanic White patients, 0.080 [95% CI, 0.071-0.089]), but SHFP was associated with the largest improvements in receipt of bone-protective medications (risk difference for racial and ethnic minority patients, 0.149 [95% CI, 0.121-0.178]; risk difference for non-Hispanic White patients, 0.181 [95% CI, 0.173-0.190]). While receiving care at an SHFP was associated with improved probability of receiving guideline-concordant care in both race and ethnicity groups, greater improvements were seen among non-Hispanic White patients compared with racial and ethnic minority patients. Conclusions and Relevance: Older adults who received care at an institution with an SHFP were more likely to receive guideline-concordant care (bone-protective medication, WBAT-POD1, and VTE prophylaxis), regardless of race and ethnicity. However, the probability of receiving guideline-concordant care at an institution with an SHFP increased more for non-Hispanic White patients than racial and ethnic minority patients.

National trends in distribution of underrepresented minorities within United States general surgery residency programs: A longitudinal panel study.

BACKGROUND: Cultural affinity with a provider improves satisfactoriness of healthcare. We examined 2005-2019 trends in racial/ethnic diversity/inclusion within general surgery residency programs. METHODS: We triangulated 2005-2019 race/ethnicity data from Association of American Medical Colleges surveys of 4th-year medical students, the Electronic Residency Application Service, and Accreditation Council for Graduate Medical Education-affiliated general surgery residencies. Temporal trends in minority representation were tested for significance. RESULTS: Underrepresented racial/ethnic minorities in medicine (URiMs) increased among graduating MDs from 7.6% in 2005 to 11.8% in 2019 (p < 0.0001), as did their proportion among surgery residency applicants during 2005-2019 (p < 0.0001). However, proportions of URiMs among general surgery residents (≈8.5%), and of programs without URiMs (≈18.8%), stagnated. CONCLUSIONS: Growing URiM proportions among medical school graduates and surgery residency applicants did not improve URiM representation among surgery trainees nor shrink the percentage of programs without URiMs. Deeper research into motivators underlying URiMs' residency program preferences is warranted.

Does Adjusting for Social Desirability Reduce Ceiling Effects and Increase Variation of Patient-Reported Experience Measures?

Social desirability bias (a tendency to underreport undesirable attitudes and behaviors) may account, in part, for the notable ceiling effects and limited variability of patient-reported experience measures (PREMs) such as satisfaction, communication effectiveness, and perceived empathy. Given that there is always room for improvement for both clinicians and the care environment, ceiling effects can hinder improvement efforts. This study tested whether weighting of satisfaction scales according to the extent of social desirability can create a more normal distribution of scores and less ceiling effect. In a cross-sectional study 118 English-speaking adults seeking musculoskeletal specialty care completed 2 measures of satisfaction with care (one iterative scale and one 11-point ordinal scale), a measure of social desirability, and basic demographics. Normality of satisfaction scores was assessed using Shapiro-Wilk tests. After weighting for social desirability, scores on the iterative satisfaction scale had a more normal distribution while scores on the 11-point ordinal satisfaction scale did not. The ceiling effects in satisfaction decreased from 47% (n = 56) to 2.5% (n = 3) for the iterative scale, and from 81% (n = 95) to 2.5% (n = 3) for the ordinal scale. There were no differences in mean satisfaction when the social desirability was measured prior to completion of the satisfaction surveys compared to after. The observation that adjustment for levels of social desirability bias can reduce ceiling effects suggests that accounting for personal factors could help us develop PREMs with greater variability in scores, which may prove useful for quality improvement efforts.

Religiosity, Acculturation, and Preterm Birth in Mexican-Origin Women: A Pilot Study.

INTRODUCTION: Explanations for racial disparities in preterm birth (PTB) are elusive, especially when comparing high rates in some racial groups with low rates in Mexican-immigrant women. The purpose of this study was to examine potential protective factors against PTB such as religiosity and acculturation. METHODS: This study was a prospective investigation of Mexican- and U.S.-born pregnant women. Women were recruited from a low-income-serving prenatal clinic in Texas. Survey instruments included socioeconomic variables, acculturation, and religiosity/spirituality (R/S). Logistic regression was used to examine the associations between acculturation, religiosity, and PTB. Because of the low prevalence of PTB in our sample, we were not able to adjust for confounding characteristics. RESULTS: Ninety-one low-income women, mostly Mexican immigrants, participated in the study. PTB in our sample was lower than the national average in the United States (5.5% vs. 9.9%) and was positively but moderately associated with high R/S. R/S scores were high, particularly for frequency of attendance, prayer, and religious coping. Women with lower acculturation had higher scores on the religiosity measures. CONCLUSION: Further research is needed with a larger sample to include other ethnic and racial minorities to more fully understand the relationships between acculturation, religiosity, and PTB.
