Stress Injuries to Bone in College Athletes: A Retrospective Review of Experience at a Single Institution. Correlation of Clinical Symptoms and Scintigraphy with a New Magnetic Resonance Imaging Grading System. Fredericson M, Bergman A, Hoffman K, Dillingham M. Report the findings in a descriptive manner, adding in brackets the grade and the author of a grading system (e.g. Talk to the referring clinicians to reach a consensus regarding the used grading system Grade 4: severe marrow oedema on both fat-suppressed T2WI and T1WI or periosteal oedema plus visible fracture line on T1WI or T2WIĭue to the presence of several grading systems, the radiological report may be unclear if only an injury grade is given, without any further details. Grade 3: severe marrow oedema on both fat-suppressed T2WI and T1WI or periosteal oedema, without a fracture line Grade 2: moderate marrow oedema on fat-suppressed T2WI (but not on T1WI) or periosteal oedema Grade 1: mild marrow oedema on fat-suppressed T2WI (but not on T1WI) or periosteal oedema As a result, both bone marrow oedema and periosteal reaction affect injury grade 3: assessed bone stress injuries in athletes at different skeletal sites and combined the criteria of the above two grading systems. The estimated time of treatment (rest) required to return to sports activity based on this classification is 5: In contrast to Fredericson grading system, the absence or presence of periosteal reaction does not affect the injury grade. Grade 4: grade 3 findings plus visible fracture line on T1WI or T2WI Grade 3: positive marrow signal change on STIR, T2WI and T1WI, no definite cortical break Grade 2: positive marrow signal change on STIR and T2WI Grade 1: positive marrow signal change on STIR a fracture line)Īrendt et al. assessed bone stress injuries in athletes at different skeletal sites and modified the Fredericson grading system, adding STIR sequence to the assessment 2: Grade 4b: periosteal oedema, extensive bone marrow oedema visible on T1WI and fat-suppressed T2WI and linear region of intracortical signal change (i.e. Grade 4a: periosteal oedema, extensive bone marrow oedema visible on T1WI and fat-suppressed T2WI and multiple focal areas of intracortical signal changes Grade 3: periosteal oedema and extensive bone marrow oedema visible on T1 and fat-suppressed T2WI Grade 2: periosteal oedema with mild bone marrow oedema visible only on fat-suppressed T2WI Grade 1: periosteal oedema with no associated bone marrow abnormalities created an MRI grading system initially developed to grade medial tibial stress injuries but has since been applied elsewhere 1,4: Classification Fredericson grading systemįredericson et al. MRI grading systems for bone stress injuries are a useful tool in assessing the extent of clinical findings related to bone stress injury and predicting the time to return to full activity, the latter being especially important for athletes.
