Bone Abstracts

Radiographs of the second metacarpal are used to assess bone strength development in paediatric populations. Children with achondroplasia and osteogenesis imperfecta (OI) have known differences in bone strength. Details of how bone strength develops and compares within these populations to unaffected children are lacking. A data set for patients with achondroplasia and OI was established.A retrospective IRB-approved review of bone-age films (n=6...

Objective: The purpose of this ongoing study was to determine whether osteogenesis imperfecta (OI) patients entering adulthood should continue with bisphosphonate therapy or would benefit from switching to a RANKL blockade therapy. To address this question, we used a mouse model of type-III OI.Methods: Under IACUC-approval, +/+ and oim/oim mice were treated from 2–26 weeks (n=20/treatment/genotype) with either 1) saline 24 weeks; 2...

Objectives: The objective of this study is to characterize patterns of bone morphology in children with osteogenesis imperfecta (OI), using measurements of the second metacarpal. A secondary objective is to look for impact of bisphosphonate treatment on bone morphology in this population.Methods: This is an IRB-approved retrospective review of 82 de-identified bone age films (AP hand/wrist) for 42 children with OI (17M, 25F). Measurements (Sectra IDS 7 P...
