The EOS technique represents a unique imaging modality combining low radiation exposure with high image quality. As its applications for pelvic imaging may increase with time, we performed a pilot ...study to evaluate the validity and reliability of this technique for the assessment of gross pelvic and acetabular morphology.
Consecutive conventional and EOS radiographs of a human cadaveric pelvis were made in 5° intervals of sagittal tilt and axial rotation (range, -15° to 15° for each). Six measurements were made on each image: (1) the vertical distance between the sacrococcygeal joint and the upper border of the pubic symphysis, (2) the horizontal distance between the midpoints of these structures, (3) the distance between the anterior superior iliac spines, (4) the distance between the facets of S1, (5) the Sharp angle, and (6) the Tönnis angle. Coxa profunda and crossover signs were also evaluated. The findings of the two imaging techniques were correlated with each other and with true linear measurements made on the cadaveric pelvis. All measurements were performed by two independent observers, and one observer repeated all measurements to assess reproducibility. Both observers were blinded to the true linear measurements made on the pelvis.
There was a strong correlation between the results of the conventional and EOS radiography (Pearson correlation coefficient, 0.644 to 0.998), and both modalities had high intraobserver and interobserver reproducibility (intraclass correlation coefficient, 0.795 to 1.000). Intraobserver and interobserver agreement on the presence of coxa profunda were both 100%. Intraobserver agreement (96.2%) and interobserver agreement (92.3%) on the presence of the crossover sign were marginally lower. Linear measurements differed significantly between the two modalities because of distortion caused by magnification effects in the conventional radiographic imaging (p < 0.05).
The EOS imaging technique proved reliable for the assessment of gross pelvic and acetabular morphology, and it may be an alternative to current radiography for primary imaging in the pediatric population and potentially in adults as well. This study did not evaluate the ability of EOS imaging to detect subtle radiographic anatomic abnormalities.
Whercas John F. Kennedy encouraged Americans to view his Catholic faith as a private matter, Joe Biden has made his faith a defining element of his public identity» Biden wears a rosary bracelet, ...casually crosses himself during conversations with foreign dignitaries, and likes to conclude speeches by quoting from the anthem of postconciliar American Catholicism, "On Eagle's Wings»" In his 2007 memoir, he writes that what he learned from the Catholic Church has "always been the governing force" in his political career» Biden has famously broken with Catholic teaching on matters such as abortion and same-sex marriage, but his insistence on his Catholic identity deserves to be taken seriously» It reflects the continuing appeal-and persistent failure-of a certain idea of Catholic politics, one that seeks to recapture the achievements of mid-century by placing one foot in left-wing politics and the other in the Catholic faith» Biden's invocation of his Catholic identity recalls an earlier period of American history, when white Catholics were stalwarts of the Democratic Party and guarantors of the postwar consensus» In i960 when Biden was a senior in high school, 82 percent of white Catholics voted for John E» Kennedy» In 1964, 78 percent voted for Lyndon B» Johnson» In 2020, however, almost two-thirds of white Catholics who go to church weekly voted against Biden, their co-religionist, and for Donald Trump» By recalling what the political scientist Ryan Burge has called "the myth of the white Catholic Democrat," Biden evokes the postwar era to which Americans in various ways seem to be drawn-whether they lament the rise of neoliberalism or the decline of the family» In this way, Biden's religious displays reinforce his broader public presentation. Yet those who would celebrate Biden's economic policies must also weigh his social policies. ...in 2012, as vice president, he surprised the White House by endorsing gay marriage. Today, colleges, not white ethnic communities, are the most formidable redoubts of Democratic power.

Fractures about the elbow in children are common and varied. Both diagnosis and treatment can be challenging, and optimal treatment protocols continue to evolve with new research data. This article ...reviews common complications related to pediatric elbow fractures and presents recent literature to help guide treatment.
THE ANTI-FAMILY RIGHT Schmitz, Matthew

Journal Article
Whereas social conservatives object to surrogacy and dread the advent of artificial wombs, some anti-family antifeminists celebrate science's power to overcome biological limits. ...Christians, ...following St. Paul, can concede that family life isn't the highest thing. Where they go wrong is in suggesting that family life is an actual evil, rather than a lower good. Far from inaugurating a revolution, anti-family politics may serve as a comforting fiction for those who find marriage and family life hard to achieve.
For many observers, the event testified to the success of Title IX, the civil rights provision associated with increased opportunities for female athletes. In 1924, a facetious item in the student ...newspaper at Doane College skewered the high-school girls' basketball tournament as a sign that women "not only want equality of rights but they want to be MEN." In 1924, the Nebraska High School Athletic association amended its constitution to read, "No school can hold membership in the Nebraska High School Athletic association that has any part in any girls' basketball tournament-local, county, district or state." Under six-player rules, dribbling was strictly limited, stealing the ball was forbidden, and players were confined to certain areas of the court.
Hip dislocation following hip arthroscopy is a devastating complication. Previous reports of arthroscopy-related iatrogenic instability have focused on strategies aimed at restoring the stabilizing ...effects of the hip joint capsuloligamentous complex. Less has been written about treatment options for patients in whom deficient acetabular coverage of the femoral head is implicated in the functionally unstable hip joint. Given this relative paucity of information, an optimal treatment approach has yet to be elucidated for these patients. Periacetabular osteotomy has been described as a treatment for iatrogenic hip instability related to surgical hip dislocation; however, to our knowledge, this is the first case of a patient with hip arthroscopy-related iatrogenic instability manifesting as recurrent, frank dislocations treated with periacetabular osteotomy.
