![]() In another study, the outcome was similar to our results. Naturally, patients treated after fracture union had additional periods of immobilization. Breaks in bones resulting from low bone mass and microarchitectural deterioration characteristic of osteoporosis. Primarily, treatment of enchondroma in the presence of a pathologic fracture did not change the outcome compared with lesions treated after fracture union.It is generally caused by a fall from a standing height or lower and usually involves the spine, hip, or wrist. A pathologic bone fracture due to osteoporosis.symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified ( R00- R94)ĭiseases of the musculoskeletal system and connective tissue.injury, poisoning and certain other consequences of external causes ( S00-T88).endocrine, nutritional and metabolic diseases ( E00- E88).congenital malformations, deformations, and chromosomal abnormalities ( Q00-Q99).complications of pregnancy, childbirth and the puerperium ( O00-O9A).compartment syndrome (traumatic) ( T79.A-).certain infectious and parasitic diseases ( A00-B99).certain conditions originating in the perinatal period ( P04- P96).code to identify major osseous defect, if applicable (.A fracture arising within abnormal bone is termed 'pathological.'. High force is required to fracture a normal bone, but diseased bones may fracture as a result of low impact trauma. Osteoporosis is the most common cause of pathological fractures. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition. Pathological fractures arise in bones weakened by disease. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. The code title indicates that it is a manifestation code. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. 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.Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. 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. The term pathological fracture is usually reserved for tumors, either benign or malignant, although it has been used in the setting of osteomyelitis.
