“…Positive findings from MRI or CT provide strong evidence for the presence of a scaphoid fracture; however, positive findings from bone scintigraphy are insufficient to confirm fracture. The prevalence of true scaphoid fracture we presented was greater than that used by some investigators to calculate the posttest probability [1,42], but similar to the result of a recent epidemiologic study [29], in which the prevalence of true scaphoid fracture in patients with suspected scaphoid fracture was 16%. The prevalence of abnormality in a study sample rarely can be generalized beyond the study except when the study is based on a suitable random sample [15].…”

“…To avoid undertreatment of these occult fractures, patients with suspected scaphoid fractures (high clinical probability of a scaphoid fracture but negative or equivocal radiographs) usually are treated with cast immobilization followed by repeat clinical examination and radiographs [46]. As the prevalence of true fractures among patients with suspected scaphoid fractures might be only 5% to 10% [1], the majority of these patients are overtreated, which results in lost work days and productivity and increased healthcare costs [11].…”

“…He concluded that unless there was a clear lucent line, a distinct break, or step-off in the cortex, x-rays could not be relied upon for accurate diagnosis of scaphoid fracture. Adey, however, was able to demonstrate between 77 and 94% accuracy in detecting scaphoid fractures utilizing CT [1]. Given the increased accuracy of CT in detecting scaphoid fractures and assessing fracture deformity, we incorporated CT in our study to better visualize the scaphoid fracture mobility.…”
