“…These reports indicate that the pain locations that patients present do not necessarily correspond to fracture sites, especially in RA. Radiographs have a sensitivity of 37%, a specificity of 79% and an accuracy of 60% for detection of bone stress injuries of the pelvis and lower extremities, whereas MRI has a sensitivity of 100%, a specificity of 86%, and an accuracy of 95% for these injuries [13,14]. MRI has thus become the best choice for diagnosing an occult hip fracture in a patient with normal radiographs.…”

Co-occurrence of subchondral insufficiency fracture of the femoral head and contralateral femoral neck fracture in a rheumatic patient receiving steroid treatment

et al. 2008

We describe a 79-year-old woman with rheumatoid arthritis who suffered from subchondral insufficiency fracture of the femoral head (SIF) and contralateral femoral neck fracture. Radiographs obtained two months after the onset of thigh pain showed collapse of the right femoral head and contralateral femoral neck fracture. MRI revealed a subchondral serpiginous low-intensity band in the right femoral head on the T2-weighted image. This case report suggests that SIF should be considered in the differential diagnoses of rheumatic patients who suffer from thigh pain without antecedent trauma.

“…Our findings are in accordance with those of Rubin et al [17], who also found early MRI most cost-effective compared to delayed bone scanning in the evaluation of patients with suspected hip fractures. Furthermore, MR imaging is more sensitive than bone scintigraphy [18].…”

The advantages of MRI in the detection of occult hip fractures

et al. 2004

While the displaced hip fracture can be visualized easily by plain radiography, the non-displaced fracture may be radiographically occult and require different imaging modalities, e.g., MRI for proper visualization. The accuracy of readers and cost advantages of utilizing MRI have not been assessed. Therefore, we undertook a study of these factors. The medical records of all patients who had visited the emergency room from June 2002 until May 2003 with a clinically suspected hip fracture, negative or equivocal plain film and subsequent MRI examination were retrospectively reviewed. Two senior and two junior radiologists independently evaluated both the MR images and radiographs of all 33 patients in a blinded study. One of three possible evaluations was described for the images of each modality: absence, presence or possibility of fracture. The economic consequences of using MRI in the detection of occult hip fractures were calculated. For all four doctors participating in this study, MRI proved to be far more sensitive and specific in the detection of occult hip fractures than radiography. Using the MR images, the senior radiologists identified the occult hip fracture patients with 100% accuracy and were in complete agreement. The agreement between junior and senior radiologists was high (average kappa=0.75). MRI also detected soft tissue injuries in 39% of the patients that could not be identified with radiography. Adoption of the new protocol using MRI saves hospitals from Euro 242 to 627 per patient. By shortening the time to diagnosis and permitting a superior visualization of both bone and soft tissue injuries, MR imaging prevents unnecessary hospitalization and delays in definitive treatment. MR images should be assessed by senior radiologists.

“…However, scintigraphy is not specific, it can be difficult to interpret and the abnormal uptake may persist for several months [3,14]. MRI has the advantage of being both very sensitive and specific and has been shown to be the gold standard for the assessment of stress fractures [15]. It also allows permits assessment of the surrounding structures that may cause heel pain, it can exclude other pathological processes such as malignancy and infection and is noninvasive and free from ionising radiation [16].…”

MR imaging, bone scintigraphy, and radiography in bone stress injuries of the pelvis and the lower extremity

Abstract: MR imaging is more sensitive than two-phase bone scintigraphy, and MR imaging should be used as the gold standard in the assessment of stress injuries of bone. Radiography reveals mainly the late phases of bone stress injuries, such as stress fracture and callus.
