Osteogenesis imperfecta in a Nigerian neonate: a case report
1Department of Radiology, University of Ilorin Teaching Hospital, Ilorin, Nigeria.
Background:
Osteogenesis imperfecta is an inherited disease where the basic pathology is of defective collagen. It is a rare disorder with a reported incidence of 1/25000-1/30000. Four variants are recognized clinically, of which type II is the most severe form. Clinically the hall marks of the disease are multiple fractures and osteopenia.
Objective:
This case is being presented because of its rare incidence, and to highlight the radiological features distinguishing it from battered baby syndrome occurring from child abuse.
Case Reports:
An eight day old Nigeria neonate, with clinico radiological features highly suggestive of type II osteogenesis imperfecta is presented.
Conclusion:
Emphasis on the radiological features, especially those distinguishing it from battered baby syndrome which has a similar appearance are discussed.

The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
01:27Fractures: 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...

01:09Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
01:27Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
