“…In an aging population the incidence of hip fractures increases exponentially with age, with an estimated annual incidence of 6.3 million world-wide in 2050 [1,2]. Most hip fractures can be diagnosed straightforwardly with radiography [3] but nondisplaced fractures may be radiographically suspect or occult, necessitating further investigation with modalities such as computed tomography (CT) [4] or magnetic resonance imaging (MRI) [5].…”

“…The criteria for further imaging with MRI being undertaken within 48 hours of presentation were the same as those described by Chana et al 2 : negative AP pelvic and lateral hip radiographs and a strong clinical suspicion of fracture with persistent pain in the groin after trauma, inability to bear weight and pain on attempted passive rotation or axial loading tests.…”

“…In order to avoid missing these occult fractures, several studies have recommended the use of MRI in patients in whom fracture of the hip is suspected clinically, but whose radiographs are negative. [2][3][4][5][6][7] The aim of this retrospective study was to find the most efficient and economical MR imaging sequences necessary to diagnose an occult fracture of the hip in these patients.…”

A delay in establishing the diagnosis of an occult fracture of the hip that remains unrecognised after plain radiography can result in more complex treatment such as an arthroplasty being required. This might be avoided by earlier diagnosis using MRI. The aim of this study was to investigate the best MR imaging sequence for diagnosing such fractures. From a consecutive cohort of 771 patients admitted between 2003 and 2011 with a clinically suspected fracture of the hip, we retrospectively reviewed the MRI scans of the 35 patients who had no evidence of a fracture on their plain radiographs. In eight of these patients MR scanning excluded a fracture but the remaining 27 patients had an abnormal scan: one with a fracture of the pubic ramus, and in the other 26 a T 1 -weighted coronal MRI showed a hip fracture with 100% sensitivity. T 2 -weighted imaging was undertaken in 25 patients, in whom the diagnosis could not be established with this scanning sequence alone, giving a sensitivity of 84.0% for T 2 -weighted imaging.If there is a clinical suspicion of a hip fracture with normal radiographs, T 1 -weighted coronal MRI is the best sequence of images for identifying a fracture.

“…Over the past two decades, it has become an accepted modality for assessing occult fractures of the femoral neck [2,5,8,18,21] and staging osteonecrosis of the femoral head [3,15,23]. More recently, it has emerged as a modality for the assessment of hip deformity [1,12], articular cartilage disease [9,11,14], acetabular labral pathology [4,6,10,19,20], inflammatory or infectious disease [13,16], and reactions to metal-on-metal THAs [7].…”

Background Although MRI is frequently used to diagnose conditions affecting the hip, its cost-effectiveness has not been defined. Questions/purposes We performed this retrospective study to determine for patients 40 to 80 years old: (1) the differences in hip MRI indications between orthopaedic and nonorthopaedic practitioners; (2) the clinical indications that most commonly influence treatment decisions; (3) the likelihood that hip MRI influences treatment decisions separate from plain radiographs; and (4) the cost of obtaining hip MRI studies that influence treatment decisions (impact studies). Methods We retrospectively assessed 218 consecutive hip MRI studies (213 patients) at one institution over a 5-year interval. Medical records, plain radiographs, and MRI studies were reviewed to determine how frequently individual MRI findings determined treatment recommendations (impact study). The cost estimate of an impact study was calculated from the product of institutional MRI unit cost (USD 436) and the proportion of impact studies relative to all studies obtained either for a specific indication or by an orthopaedic/nonorthopaedic clinician.
