Objectives: The aim of this study was to examine the early results of patients with acetabular dysplasia treated with the use of uncemented acetabular components and without complex bony augmentation. Materials and Methods: Eleven patients (13 hips) were included in this study. The median acetabular component size was 44mm (range, 44- 56mm). The mean follow up period was 24 months (range, 15-59 months). All patients were pain free at follow up. Results: The mean Merle d'Aubigné Postel score increased from 3 to 17. Our early results suggest that acetabular reconstruction using a small cementless cup, may be an alternative to previously described methods of total hip arthroplasty in the presence of superolateral bone loss.

The Encouraging Novel Amelogenesis Models and Ex vivo cell Lines (ENAMEL) Development workshop was held on 23 June 2017 at the Bethesda headquarters of the National Institute of Dental and Craniofacial Research(NIDCR). Discussion topics included model organisms, stem cells/cell lines, and tissues/3D cell culture/organoids. Scientists from a number of disciplines, representing institutions from across the United States, gathered to discuss advances in our understanding of enamel,as well as future directions for the field.
