Acetabular dysplasia and posterior wall fractures: The missing link?

BACKGROUND: Traumatologists are unable to predict hip instability based on CT scans and standard radiographs in posterior wall (PW) fractures comprising <50-60 % of the wall, necessitating an examination under anesthesia (EUA). Risk factors for instability have not been clarified, but acetabular dysplasia has been theorized as a potential etiology. Unfortunately, dysplasia is difficult to evaluate in the traumatic setting. The purpose of this study was to compare acetabular morphology between unstable and stable fractures with a novel method to detect dysplasia. METHODS: Patients ≥ 18 years old with a PW fracture that underwent an EUA from 2013 to 2023 were retrospectively identified. For our experimental measurements, the axial distances on CT between the acetabular dome, lateral acetabular opening, and femoral head vertex were recorded. Acetabular geometry was quantified at these levels. Conventional dysplasia metrics (e.g., Tonnis angle) were obtained. Variables were compared between stable and unstable fractures. RESULTS: 58 patients met inclusion criteria with 42 stable versus 16 unstable fractures. Unstable fractures had higher distances between the acetabular dome and femoral head vertex (p > 0.05). They had more cranial fracture exit points (p = 0.0015), lower femoral head coverage (p = 0.0102), and lower posterior acetabular sector angles (p = 0.0281). No other differences in acetabular geometry, demographics, injury characteristics, or other markers of dysplasia were identified. CONCLUSIONS: Unstable hips demonstrated a more recessed acetabular dome when compared to stable hips. Posterior acetabular femoral head coverage and cranial fracture exit point may be related to hip instability. A larger sample size is needed to validate these findings.

Evaluation of Hip Preservation-related Patient Education Materials From Leading Orthopaedic Academic Centers in the United States and Description of a Novel Video Assessment Tool.

The readability, reliability, and quality of online hip preservation-related patient education materials from the top 20 orthopaedic academic centers in the United States were evaluated. Methods: The patient educational materials were evaluated with the following assessment tools: Flesch-Kincaid (FK) readability test, Flesch Reading Ease formula, LIDA instrument, and DISCERN tool. Videos were assessed using the Patient Educational Video Assessment Tool (PEVAT), an author-developed scoring system. Results: A total of 121 educational items were reviewed. Median (interquartile range) or mean ± SD of the FK level, Flesch Reading Ease, LIDA, and DISCERN scores were 11.00 (3.00), 47.32 ± 12.14, 41.00 (6.00), and 64.00 (7.00), respectively. Higher ranking was correlated with higher FK (ρ = -0.21, P value = 0.034), higher DISCERN score (ρ = -0.39, P value < 0.005), and a lower PEVAT score (r = 0.61, P value = 0.034). The PEVAT score found that 83% of videos were classified as high quality. Discussion: An analysis of the hip preservation patient education text articles found low readability. Overall, high ranking was associated with poorer readability, higher quality text content, and lower quality video content. Video content was found to be predominantly of high quality. Improving the educational accessibility and effect of hip preservation-related topics may result in improved treatment outcomes.

Social Determinants of Health and Oral Cavity Cancer Treatment and Survival: A Competing Risk Analysis.

OBJECTIVE: Competing risk analysis is a powerful assessment for cancer risk factors and covariates. This method can better elucidate insurance status and other social determinants of health covariates in oral cavity cancer treatment, survival, and disparities. STUDY DESIGN: Retrospective cohort study using the Surveillance, Epidemiology, and End Results (SEER) database. METHODS: Data regarding patient characteristics, clinical stage at diagnosis, treatment, and survival data for 20,271 patients diagnosed with oral cavity cancer was extracted from the SEER 18 Regs Research Data including Hurricane Katrina Impacted Louisiana Cases from 1973 to 2014. All statistical analyses were performed using SAS 9.5 (SAS Institute Inc., Cary, NC). The Fine-Gray method for assessing impact, risk, and covariates was employed. RESULTS: Medicaid patients presented with later stage disease, larger tumor size, more distant metastases, and more lymph node involvement at diagnosis compared to insured patients. Medicaid patients were less likely to receive cancer-directed surgery. Medicaid status was also associated with worse cancer-specific survival (subhazard ratios 1.87, 95% confidence interval 1.72-2.04, P < .0001) after adjustment for all covariates. CONCLUSION: This is the first study examining specifically how Medicaid status and social determinants of health covariates impact oral cavity cancer treatment and outcomes and is the first using methods validated for complex covariates. Patients with Medicaid present with more extensive oral cavity disease burden are less likely to receive definitive therapy and have significantly worse overall survival than those with other forms of insurance. This better identifies disparities and the need for improving health literacy, specifically for the at-risk Medicaid population, and can guide clinicians.

Establishing a Multidisciplinary Approach to the Management of Neurologic Disease Affecting the Urinary Tract.

Neurologic diseases often affect the urinary tract and may be congential or acquired. The progressive nature of many neurologic diseases necessitates routine surveillance and treatment with a multidisciplinary approach. Urologic treatments may interact with pharmacologic or procedural interventions planned by other specialists, mandating close coordination of care and communication among providers. Primary care and nursing often can serve as the quarterbacks of the multidisciplinary team by identifying when a slowly progressive condition warrants further investigation and management by specialists.
