![]() Scoring systems have been developed to assess the fracture risk of bone metastases, the Mirels classification is the one that has gained the most traction, although its poor sensitivity (35%) means that it is not without its controversy 5. In principle, every osteolytic focus in the femoral neck or the spine is at risk of a pathological fracture. Practical pointsĪ radiologist should mention the possibility of a pathological fracture if an osteolytic metastasis is seen. Pathological fractures are feared by oncologists because they may cause immobilization of their patients, especially when the spine or lower extremities are affected. Well-defined, homogenous T1-hypointense abnormal signal without normal intervening marrow signalĭiffuse uptake of radiopharmaceutical by the lesion 4 Radiographic features Radiography and CTĭestruction or focal defect within the inner layer of bony cortex In addition, in adult patients, the avulsion of the femoral lesser trochanter should be considered a pathological fracture until proven otherwise 4. The most common location for pathological fractures are 4: Fragility fractures on the other hand, are acute fractures in osteoporotic patients due to a single event of minimal trauma. Insufficiency fractures are fractures due to multiple minor events causing a cumulative load on weakened osteoporotic bone. Paget disease, osteopetrosis), although the term insufficiency fracture is probably more correct 4. ![]() It can be used in the setting of generalized metabolic bone disease (e.g. They can be characterised from stress fractures by the presence of a well-defined T1 hypointense lesion at the fracture site completely replacing the marrow fat. S72.90XA, S72.309A, S72.409A, S72.413A, S72.416A, S72.443A, S72.446A, S72.453A, S72.456A, S72.499A, M84.453A Pathological fractures are insufficiency fractures occurring in a bone weakened by benign or malignant neoplastic lesion affecting its trabecular integrity. Pathological fracture, not elsewhere classified: M84.4įemur (thigh) fracture: 821.0, 821.2, 733.15 Osteoporosis with current pathological fracture: M80.x Other osteoporosis without current pathological fracture: M81.8 Age-related osteoporosis without current pathological fracture: M81.0
