“…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.

“…Indeed, while those rotatory maneuvers generate posterior traction on the superior labrum, joint distraction combined with axial loading is a linear motion that places inferior traction on the superior labrum. This latter technique has already been assessed in patients at the hip (7), knee (8), and wrist (9) joints, and all those studies demonstrated better distribution of intra-articular contrast material under axial traction. To our knowledge, this study is the first to prove that it is also true at the shoulder in vivo.…”

“…The value of adding axial traction to direct MR arthrography has already been assessed in vivo in the hip (7), knee (8), and wrist (9) joints, with variable success. In the shoulder, this technique has been previously evaluated on cadavers (10).…”

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.

“…MRA with axial traction has been evaluated with success in the shoulder, [11][12][13] hip, [14][15][16][17][18][19][20][21] knee, 22 wrist, [23][24][25][26][27][28][29][30] ankle 31,32 and metatarsophalangeal 33 and metacarpophalangeal joints. 34 To the best of our knowledge, there is no study comparing MRA of the elbow with and without traction.…”
