Reconstruction for pelvic discontinuity and massive acetabular defects
ConclusionThe acetabular reconstruction with the Cup-Cage system is a valid alternative for the reconstruction of massive acetabular defects (Paprosky type IIIA and IIIB) and pelvic discontinuities offering good results at short and midterm follow-up.ResumenIntroducciónLa reconstrucción acetabular con defectos óseos masivos y discontinuidades pélvicas es un procedimiento quirúrgico complejo que presenta importantes dificultades para el cirujano ortopédico. El objetivo de este estudio es presentar los resultados a corto y medio plazo de la revisión acetabular con el sistema de reconstrucción Cup-Cage en una serie consecutiva de casos.Material y métodosRetrospectivamente revisamos 22 casos consecutivos de defectos acetabulares masivos (8 Paprosky IIIA y 9 IIIB); 5 discontinuidades pélvicas; 2 fracturas pélvicas durante la implantación de la prótesis primaria, y una seudoartrosis pélvica. Todos fueron revisados con un cotilo de metal trabecular y una caja de reconstrucción tipo Cup-Cage. Se realizó seguimiento clínico y radiográfico de los pacientes para detectar fallos mecánicos o aflojamientos del implante.ResultadosEn un tiempo de seguimiento medio de 45,06 meses (12-73 meses) no se objetivó ningún fracaso radiográfico del implante (migración del componente, osteólisis ni rotura de tornillos). Las complicacione...
CONCLUSIONS: The anatomic stemless press-fit implant seems to be favorable in terms of implant-related stress shielding. Clinical outcome was not affected by radiographic changes, demonstrating an 8-year clinical performance that seems to be comparable to conventional stemmed TSA.

Conclusion: This case report highlights two key points. Luckenschadel should be kept in mind when Chiari II malformation is diagnosed. Autopsy with radiographic assessment is very useful in revealing this congenital defect which may escape prenatal detection. PMID: 32096430 [PubMed - as supplied by publisher]

This article reviews the specific imaging features of CF using conventional imaging modalities (chest radiographs and high-resolution computed tomography [HRCT]) as well as emerging imaging technologies (digital chest tomosynthesis and MR imaging). In addition, the authors review the CF-specific HRCT imaging findings that are essential in the evaluation of these patients in the pre –lung transplant and post–lung transplant settings.
Background: Inpatient stroke-codes (ISC) have traditionally seen low treatment rates with IV-thrombolytic (IVT). The purpose of this study was to identify the predictors of true stroke, prevalent IVT-treatment gap and study the factors associated with such missed treatment opportunities (MTO).Methods: A retrospective chart review identified ISC from March 2017 to March 2018. Clinical, radiographic and demographic data were collected. Primary analysis was performed between stroke vs. non-stroke diagnoses. Dichotomous variables were analyzed using Chi-Square test of proportions and continuous variables with Wilcoxon-Ranked-S...

We present a case of an exceptionally rare malignant cutaneous adnexal tumor, highlighting the importance of adherence to fundamental biopsy principles for diagnosing and managing musculoskeletal lesions.
In this study, we acquired computed tomography scans of three Standardbred trotting colts longitudinally between 2 and 12 months of age. Finite-element models were constructed of the left forelimb proximal phalanx and used to assess strain energy density during quiet standing. Growth related changes in mineral density and bone area fraction in the distal epiphysis, mid-diaphysis, and proximal epiphysis were evaluated. Mineral density and bone area fraction uniformly increased in the diaphysis and strain energy density was constant during growth, indicating adaptation to quiet standing. Bone mineral density and bone area fr...
