Clinical and Roentgenologic Semiotics of Long Bone Pathologic Fractures

During 1965-2002 one thousand two hundred thirty patients with bone tumors and tumor-like diseases were treated at Astrakhan Medical Academy, Clinic of Traumatology and Orthopaedics. Out of them 163 (13.3%) patients had pathologic fractures. One hundred eight fractures were localized within long bones: humerus (61), femur (37), tibia (29), fibula (6), radius (5). Long bones fractures were commonly resulted from destructive lesions: solitary bone cyst - 48 cases, fibrous dysplasia - 26, giant cell tumor - 24, aneurismal bone cyst - 18, metaphyseal fibrous defect -11. Clinical and roentgenologic semiotics was studied and complex of roentgenologic signs of long bone pathologic fractures was systematized. Peculiarities of fractures (injury mechanism, typical localization of pathologic process, pattern of destruction focus) in various nosologic forms of primary disease were detected. The data obtained simplify diagnosis and allow trustworthy making prehistologic diagnosis as well as to choose optimum treatment tactics.
