Abstract:
A retrospective study of 44 patients with osteogenesis imperfecta treated over a 14-year period was undertaken to determine the frequency and pattern of non-unions of long bones in these patients. Nine non-unions were encountered in eight patients. Four of these non-unions developed at sites of osteotomies performed at the time of intramedullary rodding. These children have remained asymptomatic, however, without appreciable limitations in spite of the non-union. Five atrophic or gap non-unions that occurred in the humerus were following inadequately treated fractures. These children were disabled on account of the non-unions. In three patients all attempts at obtaining union failed. The other two patients were braced. We conclude that non-union in osteogenesis imperfecta is not a very rare phenomenon. We also recommend that all fractures in children with osteogenesis imperfecta must be treated with appropriate immobilization to prevent a gap non-union developing, since gap non-unions are exceedingly difficult to treat.

Compact 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...
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...
Bone 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...
Bone Formation by Intramembranous Ossification
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
Spongy 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...
