Background/Objectives: Acetabular fractures, traditionally linked to high-impact trauma in younger adults, are increasingly observed in the elderly due to falls and poor bone quality. This demographic shift necessitates updated treatment approaches. This study analyzes demographic trends and treatment evolution over a decade using the German pelvic fracture registry. Methods: Data on acetabular fractures were analyzed from the German pelvic fracture registry of the German Trauma Society. Parameters included classification, demographics, treatment methods, and surgical details. Trends were assessed by grouping patients based on treatment intervals and age, comparing treatment methods, surgical approaches, and reduction quality across these groups, considering fracture types and treatment volume. Results: The study included 2853 unilateral acetabular fractures with a mean patient age of 61.5 years, showing an increasing age trend. A shift from simple to complex fractures involving the anterior acetabular column was observed. Operative treatment was performed in 62.5% of cases, more common in non-geriatric patients and those with posterior column involvement. The use of anterior intrapelvic approaches increased over time, replacing the Ilioinguinal extrapelvic approach. Anatomical reduction was achieved in 47.4% of cases, with 31.7% having imperfect reductions and 20.9% poor reductions. High-volume centers had significantly better reduction outcomes, particularly for simple fractures. Geriatric patients exhibited worse reduction quality compared to younger patients. In-hospital mortality was stable at 3.3%. Conclusions: The study highlights a demographic shift towards an older patient population, leading to more complex fracture patterns. Despite advancements in surgical techniques and new implant technologies, these demographic changes have resulted in lower reduction quality for complex fractures. Emphasis is placed on careful patient selection for reconstructive surgery or endoprosthetic replacement to ensure high-quality outcomes. [ABSTRACT FROM AUTHOR]

Breaking has gained public attention as a form of sports activity. The associated intense movements of the hip joints are possibly linked to the development of femoroacetabular impingement (FAI). Therefore, this study aimed to assess clinical and radiographic FAI measures in professional breakers compared to hobby athletes. The study cohort consisted of professional breakers with persisting hip pain who were 1:1 matched to a cohort of FAI patients without professional sports careers from our outpatient clinic. The primary endpoint assessed on standardized plain radiographs was the alpha angle (AA). Further measures were the acetabular index (AI), lateral center-edge angle (LCEA), crossover sign, ischial spine sign, and femoral head extrusion index (FHEI). The modified Harris Hip Score (mHHS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score were used to obtain patient-reported measures. We recruited ten professional breakers and matched them to ten hobby athletes. The median AA was significantly higher in the breakers compared with the hobby athletes (73° [IQR 66.5°, 84.2°]) vs. 61.8° [IQR 59.5°, 64.8°], p = 0.0004). There was a significant reduction in weekly training hours in breakers after diagnosis (13.0 hours [interquartile range [IQR] 9.5, 32.4] to 1.5 hours [IQR 0, 4.8], p = 0.0039). There were no inter-group differences regarding mHHS, WOMAC, and additional radiographic measurements. Breakers have higher AA in cam-type FAI compared to nonprofessional athletes. The corresponding hip pain significantly reduced training hours and caused the end of their breaking career. The potentially high prevalence of FAI in breakers and the corresponding consequences need to be considered early when athletes present with hip pain. [ABSTRACT FROM AUTHOR]
