ABSTRACT

Objective To analyze the causes for the femoral head osteonecrosis misdiagnosed as lumbar disc herniation.Methods Thirty cases of lumbar disc herniation receiving lumbar CT and MRI were collected,and the causes of misdiagnoses were analyzed.Results Twenty-nine cases with femoral head osteonecrosis were misdiagnosed as lumbar disc herniation.And the diagnosis of femoral head osteonecrosis was missed in a single case of lumbar disc herniation combined with femoral head necrosis.Conclusions The major factors of misdiagnoses and missed diagnosis are the neglect of physical examination,lack of detailed clinical history data collection,excessive reliance on imaging findings,and the absence of necessary differential diagnosis of similar symptoms.
