Abstract:
Hyperplastic callus (HPC) formation is a prominent feature of osteogenesis imperfecta (OI) type V; however, little is known about its long-term outcome. In this case report we describe the occurrence, appearance and course of a femoral HPC in a patient with OI type V during 10 years of follow-up. Radiographs of HPC in this child were compared and contrasted with HPC formation in the femur of his father and paternal grandfather, who also were affected with OI type V. This case report makes it clear that HPC can lead to significant morbidity, not only in the acute phase but also long term as a result of residual alteration in bone architecture.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
