However, some recent reports have suggested that these disparities may not be as present in the pediatric population. It is unknown which measure of social determinants of health (SDOH) best captures outcome disparities, such as geospatial measures like the Area Deprivation Index (ADI) or patient-level measures such as insurance type or poverty rates, for osteosarcoma.</p><p><strong>Questions/purposes: </strong>(1) Are different measures of SDOH associated with differences in the presentation of osteosarcoma, (2) differences in the initiation and completion of treatment, and (3) differences in survival outcomes?</p><p><strong>Methods: </strong>This was a single-institution, retrospective, comparative study of 88 children, adolescents, and young adults diagnosed with high-grade osteosarcoma between 2010 and 2024. The ADI and other measures of SDOH previously investigated by other authors, including the Childhood Opportunity Index (COI), insurance type, US Census Tract poverty level, and self-reported race or ethnicity, were determined for each patient. The ADI scores were grouped into low (< 75th percentile) and high (≥ 75th percentile) deprivation groups, and the COI was classified as low (≤ 25th percentile) and high (> 25th percentile) opportunity, based on prior National Cancer Database (NCDB) and Surveillance, Epidemiology, and End Results (SEER) studies, which showed worse outcomes in patients in the bottom quartile of income. Data on patient age, gender, primary site, presence of metastasis, treatment including chemotherapeutic regimen and surgical treatment, chemotherapeutic response, and outcomes (including overall survival, metastasis-free survival, local recurrence-free survival, and relapse-free survival) were gathered from the medical record. Whether the patient presented to an acute care setting (urgent care or emergency department) or outpatient clinic was recorded. Patients with Medicaid and those with no insurance were compared with those with commercial insurance. Symptom duration before diagnosis and treatment timelines were compared against various measures of SDOH. Survival outcomes were also compared among SDOH groups. A multivariable Cox regression analysis including ADI group, tumor size, and presence of metastatic disease was performed to look for factors independently associated with survival.</p><p><strong>Results: </strong>Patients in the high deprivation group presented to an acute care setting more frequently than the low deprivation group (51% [20 of 39] versus 22% [10 of 45], OR 1.9 [95% confidence interval (CI) 1.2 to 2.9]; p = 0.006) and had greater median (IQR) symptom duration (13 weeks [6 to 22] versus 6 weeks [4 to 11]; p = 0.002).

Gluteus minimus indentation, a lateral femoral head morphologic finding, has been described in patients with cerebral palsy and severe dysplasia; however, whether it occurs in other instability-related hip morphologies and whether it has clinical relevance remains unclear.</p><p><strong>Questions/purposes: </strong>(1) Did a higher percentage of patients with hip dysplasia (defined as a lateral center-edge angle [LCEA] < 22°) have gluteus minimus indentation than patients without dysplasia? (2) Was there an association between gluteus minimus indentation and acetabular or femoral radiological parameters? (3) Were there differences in three-dimensional (3D) cartilage and labral parameters between hips with and without gluteus minimus indentation?</p><p><strong>Methods: </strong>Between November 2019 and December 2024, 761 hips (703 patients) underwent MR arthrography for nontraumatic hip pain at our institution and were included in this retrospective, single-center study. MR arthrography was ordered for patients whose hip pain had not improved after at least 3 months of conservative treatment and who were being considered for hip preservation surgery. We excluded 47% (357 of 761) of hips for previous hip surgery, trauma, avascular necrosis, advanced osteoarthritis, tumors, childhood conditions, or inadequate imaging, and a further 2% (12 of 761) to retain one hip per patient, leaving 392 hips for analysis. The included patients had a mean ± SD age of 32 ± 10 years, and 58% (229 of 392) of patients were females. In all, 18% (69 of 392) had dysplasia (LCEA < 22°) and 59% (231 of 392) had increased femoral torsion (> 25°). No patients had cerebral palsy. Gluteus minimus indentation and its topographic distribution, reported using a clockface system, were assessed on radial MR sequences. Radiographic parameters were measured on AP pelvis radiographs. Three-dimensional models of the acetabular cartilage and labrum were generated from an MRI sequence (magnetization-prepared 2 rapid gradient-echo) that produces high-contrast images in which cartilage and the labrum can be clearly distinguished. The models were created using a previously validated deep-learning algorithm trained to outline these structures. In the validation study, agreement with manual segmentation was excellent.</p><p><strong>Results: </strong>Gluteus minimus indentation was present in 7% (29 of 392) of hips.
