What does osteofibrous dysplasia primarily affect?

Osteofibrous dysplasia is a benign bone lesion that primarily affects the long bones, most commonly the tibia and fibula. This condition typically occurs in children and young adults and is characterized by the replacement of normal bone with fibrous tissue and woven bone. The presence of osteofibrous dysplasia can lead to pain, swelling, and may cause deformities. The involvement of long bones is significant, as these sites are where the condition most commonly manifests, impacting both the structure and function of the affected bones. Understanding the specific locations commonly associated with osteofibrous dysplasia helps in accurate diagnosis and treatment planning.
