“…In radiology, axial traction is used as a ''carpal stress test'' in the diagnosis of scapholunate ligament injuries (16). Furthermore, four previous studies reported the advantages of applying axial traction during MR arthrography, one at the shoulder (9), two at the hip (10,17), and one at the knee (11). Llopis et al (10) noted greater distention of the hip joint with traction, leading to improved visualization of the femoral and acetabular cartilage surfaces.…”

Llopis et al (10) noted greater distention of the hip joint with traction, leading to improved visualization of the femoral and acetabular cartilage surfaces. Palhais et al (11) found a slight but significant widening of the femorotibial joint space with traction, with a trend towards more contrast material separating the opposing cartilage surfaces.…”

Purpose: To assess the impact of axial traction during acquisition of direct magnetic resonance (MR) arthrography of the wrist with regard to joint space width and amount of contrast material between the opposing cartilage surfaces. Materials and Methods:Fifteen consecutive patients (12 male, mean age 38.1 years) were included in this Institutional Review Board-approved prospective study. Threecompartment wrist MR arthrographies were performed between October and December 2009 on a 3 T unit using a fat-suppressed T1-weighted isotropic high-resolution volumetric interpolated breathhold examination (VIBE) sequence in the coronal plane, with and without axial traction (3 kg). Two radiologists measured radiocarpal (radioscaphoid, radiolunate) and midcarpal (lunocapitate, hamatolunate) joint space widths, with and without traction, and assessed the amount of contrast material between the opposing cartilage surfaces using a threepoint scale: 0 ¼ absence, 1 ¼ partial, 2 ¼ complete.Results: With traction, joint space width increased significantly at the radioscaphoid (D ¼ 0.78 mm, P < 0.01), radiolunate (D ¼ 0.18 mm, P < 0.01), and lunocapitate (D ¼ 0.45 mm, P < 0.01) spaces, and both observers detected significantly more contrast material between the cartilage surfaces. At the hamatolunate space, the differences in joint space width (D ¼ 0.14 mm, P ¼ 0.54) and amount of contrast material were not significant. Conclusion:Direct wrist MR arthrography with axial traction of 3 kg increases joint space width at the radiocarpal and lunocapitate spaces, and prompts better coverage of the articular cartilage by the contrast material.

“…The only slight increase in joint space width could be due to muscle contraction by the patient counteracting the traction force. As Llopis et al found a joint distension at the hip with only 6-kg traction [11], it could be possible, that 15 kg was too much traction leading to increased muscle contraction.…”

“…In the second study Nishii et al compared indirect MR arthrography of the hip with traction with standard MRI without traction in the evaluation of labral lesions and found a better accuracy of indirect MR arthrography with traction [12]; however, they did not compare indirect MR arthrography with and without traction. Recently Llopis et al evaluated direct MR arthrography of the hip with leg traction [11] and found an improved visualization of the femoral and acetabular cartilage surfaces owing to a better separation of these structures. To our knowledge no studies dealing with knee MR arthrography with traction were performed.…”

“…This is thought to allow a better penetration of contrast material between the articular surfaces and the adjacent structures and thus a better delineation of the intra-articular structures and their pathology. With regard to the shoulder and the hip, there are some reports that showed superior results when traction is applied during MR arthrography [10][11][12]. But studies evaluating the effects of traction during knee MR arthrography are lacking.…”

Purpose: To assess the value of adding axial traction to direct MR arthrography of the shoulder, in terms of subacromial and glenohumeral joint space widths, and coverage of the superior labrum-biceps tendon complex and articular cartilage by contrast material.Materials and Methods: Twenty-one patients investigated by direct MR arthrography of the shoulder were prospectively included. Studies were performed with a 3 Tesla (T) unit and included a three-dimensional isotropic fat-suppressed T1-weighted gradient-recalled echo sequence, without and with axial traction (4 kg). Two radiologists independently measured the width of the subacromial, superior, and inferior glenohumeral joint spaces. They subsequently rated the amount of contrast material around the superior labrum-biceps tendon complex and between glenohumeral cartilage surfaces, using a threepoint scale: 0 ¼ no, 1 ¼ partial, 2 ¼ full.Results: Under traction, the subacromial (D ¼ 2.0 mm, P ¼ 0.0003), superior (D ¼ 0.7 mm, P ¼ 0.0001) and inferior (D ¼ 1.4 mm, P ¼ 0.0006) glenohumeral joint space widths were all significantly increased, and both readers noted significantly more contrast material around the superior labrum-biceps tendon complex (P ¼ 0.014), and between the superior (P ¼ 0.001) and inferior (P ¼ 0.025) glenohumeral cartilage surfaces.Conclusion: Direct MR arthrography of the shoulder under axial traction increases subacromial and glenohumeral joint space widths, and prompts better coverage of the superior labrum-biceps tendon complex and articular cartilage by contrast material.
