a usually unilocular, intramedullary cystic cavity in the bone. it is lined by fibrous tissue and is filled with serous or serosanguineous fluid. it can arise from any bone. the most frequent sites are proximal humerus, proximal femur, and proximal tibia. in most cases the lesion is asymptomatic and is usually detected after a pathologic fracture or during radiologic examination for unrelated reasons. recurrences have been reported in a minority of cases.
Patient EducationClinical
Bone Diseases
Your bones help you move, give you shape and support your body. They are living tissues that rebuild constantly throughout your life. During childhood and your teens, your body adds new bone faster than it removes old bone. After about age 20, you can lose bone faster than you make bone.
