What is a cortical defect in the humerus?

A cortical defect in the humerus refers to a localized area of bone loss or thinning in the outer cortical layer of the humeral bone. This can result from various causes, including trauma, infection, tumors, or metabolic bone diseases. Such defects may weaken the structural integrity of the bone, potentially leading to fractures or other complications. Diagnosis typically involves imaging studies, and treatment depends on the underlying cause and severity of the defect.
