“…(11) The difference in the femoral head diameters of these populations would be even greater if the thickness of the articular cartilage were to be taken into account, given that articular cartilage has been shown to contribute approximately 3 mm to the femoral head diameter. (12) However, we found that the thickness of the cartilage was not taken into account during the measurement of femoral head diameter in most earlier studies. (4)(5)(6) For instance, studies by Noble et al, (4) and Hoaglund and Low (5) assessed dry cadaveric bone without an intact articular surface, while Massin et al (6) mainly assessed the femoral head size radiologically.…”

“…Wyler et al ( 46 ) assessed the accuracy of multidetector CT arthrography in the hip joint by comparing physical measurements of cartilage thickness from anatomic slices to measurements acquired from multidetector CT arthrograms. They reported a mean ( 39 ) was 0.85-1.72 mm, with maximum thickness values ranging from 1.43 from 3.14 mm.…”

Purpose:To prospectively quantify the accuracy of hip cartilage thickness estimated from three-dimensional (3D) surfaces, generated by segmenting multidetector computed tomographic (CT) arthrograms by using direct physical measurements of cartilage thickness as the reference standard. Materials and Methods:Four fresh-frozen cadaver hip joints from two male donors, ages 43 and 46 years, were obtained; institutional review board approval for cadaver research was also obtained. Sixteen holes were drilled perpendicular to the cartilage of four cadaveric acetabula (two specimens). Hip capsules were surgically closed, injected with contrast material, and scanned by using multidetector CT. After scanning, 5.3-mm cores were harvested concentrically at each drill hole and cartilage thickness was measured with a microscope. Cartilage was reconstructed in 3D by using commercial software. Segmentations were repeated by two authors. Reconstructed cartilage thickness was determined by using a published algorithm. Bland-Altman plots and linear regression were used to assess accuracy. Repeatability was quantifi ed by using the coeffi cient of variation, intraclass correlation coeffi cient (ICC), repeatability coeffi cient, and percentage variability. Results:Cartilage was reconstructed to a bias of 2 0.13 mm and a repeatability coeffi cient of 6 0.46 mm. Regression of the scatterplots indicated a tendency for multidetector CT to overestimate thickness. Intra-and interobserver repeatability were very good. For intraobserver correlation, the coeffi cient of variation was 14.80%, the ICC was 0.88, the repeatability coeffi cient was 0.55 mm, and the percentage variability was 11.77%. For interobserver correlation, the coeffi cient of variation was 13.47%, the ICC was 0.90, the repeatability coeffi cient was 0.52 mm, and the percentage variability was 11.63%. Conclusion:Assuming that an accuracy of approximately 6 0.5 mm is suffi cient, reconstructions of cartilage geometry from multidetector CT arthrographic data could be used as a preoperative surgical planning tool.q RSNA, 2010

“…In addition, as the hip is situated deep in the body, loss of signal-to-noise ratio occurs, which is compounded by the lack of an effective surface coil [4]. MDCT allows for high-resolution multiplanar reformatted images to be obtained, which enable excellent assessment of both femoral ( Figure 4) and acetabular cartilage ( Figure 5) [9,18,19]. In our series we have demonstrated good correlation between the imaging and arthroscopic findings.…”

“…There are few published data on the utility of this technique in the investigation of intra-articular hip pathology. Several studies have investigated the ability of MDCT arthrography to assess cartilage loss in the hip and have demonstrated that its accuracy is equal to, or can outperform, MR arthrography [18][19][20]. There are limited reports regarding the ability of MDCT arthrography to assess labral pathology [9].…”

ABSTRACT. The aim of this study was to evaluate the role of multidetector CT (MDCT) arthrography in the diagnosis of intra-articular hip pathology. A retrospective review of 96 patients who had undergone CT hip arthrography was performed. Data regarding the presence of a labral tear, paralabral cyst, chondral loss, acetabular version, femoral morphology and fibrocystic change were collected. We detected 28 labral tears (24 anterior, 2 anterolateral, 1 lateral and 1 posterolateral). An abnormal labral-chondral transitional zone was seen in 9 patients and 4 patients had surface labral fraying. We identified three paralabral cysts. Acetabular cartilage loss was detected in 45 and femoral cartilage loss in 9 patients. An abnormal anterior femoral head and neck junction was present in 18 hips and fibrocystic change in 8. Acetabular retroversion was present in 11 hips. 63 sets of patient notes were reviewed, of which 49 were in-patients with abnormal MDCT arthrogram findings. Surgical correlation was available in 27 patients. There was a discrepancy between the findings of a labral tear in one patient (false negative, 90% sensitivity and 100% specificity) and the presence of acetabular cartilage loss (88% sensitivity and 100% specificity) and femoral cartilage loss (94% sensitivity and 100% specificity) in three patients. MDCT arthrography affords accurate detection of intra-articular hip pathology. The investigation of suspected intra-articular hip pathology is challenging. Arthroscopy represents the gold standard but is invasive, necessitates a general anaesthetic and is best reserved for patients in whom concomitant therapeutic intervention is to be undertaken. Much of the radiology literature has focused on the use of MR arthrography of the hip to detect labral and cartilage pathology [1][2][3][4][5]. A number of groups have also studied the role of non-contrast MRI in the detection of labral tears associated with femoroacetabular impingement and acetabular dysplasia [6][7][8][9]. Both non-contrast MRI and MR arthrography have limitations in terms of spatial resolution, which can make the detection of subtle labral and cartilage pathology challenging [4].Modern spiral multidetector CT (MDCT) technology allows submillimetre spatial resolution and has revitalised interest in the role of CT arthrography in the wrist, shoulder, knee, elbow and ankle [10][11][12][13][14][15][16][17]. There are few published data on the utility of this technique in the investigation of intra-articular hip pathology. Several studies have investigated the ability of MDCT arthrography to assess cartilage loss in the hip and have demonstrated that its accuracy is equal to, or can outperform, MR arthrography [18][19][20]. There are limited reports regarding the ability of MDCT arthrography to assess labral pathology [9]. The aim of this study was to evaluate the role of MDCT arthrography in the diagnosis of intraarticular hip pathology in a consecutive group of patients. Methods and materialsA retrospective review of 96 consecutive patients ...
