“…Borsa et al 4 reported the use of the posterior approach and validated ultrasound assessment as having good repeatability for asymptomatic shoulder translation, compared with stress radiography. Rathi et al 28 compared the anterior and posterior ultrasonographic approaches and concluded that the posterior approach had greater intra- and interrater reliability. Importantly, the posterior approach is advantageous because the scapular spine is useful as a bony landmark, which can be used to set the probe at a reproducible position.…”

“…In the current study, the interobserver reliability was moderate (ICC 2,1 , 0.724) and intraobserver reliability was good (ICC 1,1 , 0.810), which was comparable with previous reports that used the posterior approach. 4 , 28 This study had the advantage of using a dynamometer to perform quantitative distraction force to the humeral head during the translation test.…”

Background: Ultrasonography can be used to quantitatively assess anterior humeral head translation (AHHT) at different degrees of shoulder abduction. Risk factors for recurrent shoulder instability have been identified. Hypothesis: It was hypothesized that the number of dislocations or glenoid or humeral bone loss would be associated with more AHHT as measured using ultrasound. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 39 patients who underwent surgery for anterior shoulder instability were prospectively studied. Ultrasound assessment of AHHT was performed immediately after general anesthesia was induced. The upper arm was placed at 0°, 45°, and 90° of abduction, and a 40-N anterior force was applied to the proximal third of the arm. The distance from the posterior edge of the glenoid to that of the humeral head was measured at each abduction angle using ultrasound with and without a 40-N anterior force, and the AHHT was calculated. The differences in translation at each shoulder angle were compared. Additionally, the authors investigated the association between AHHT and demographic, radiographic, and clinical data. Results: Compared with the AHHT at 0° of abduction (5.29 mm), translation was significantly larger at 45° of abduction (8.90 mm; P < .01) and 90° of abduction (9.46 mm; P < .01). The mean translation was significantly larger in female patients than in male patients at all degrees of abduction ( P ≤ .036 for all). There was no correlation between AHHT at any abduction angle and number of dislocations, clinical data, or radiographic data (including bone loss). Conclusion: Ultrasound assessment of AHHT showed larger amounts of laxity at 45° and 90° than at 0° of abduction. Anterior glenohumeral laxity was greater in female than male patients. Glenoid or humeral bone loss did not correlate with AHHT, thereby clarifying that bone loss has no direct effect on measurements of capsular laxity in neutral rotation.

“…Clinically, ultrasound is increasingly used as a quantitative assessment of anterior translation since it allows users to evaluate the translation dynamically and non‐invasively [13, 26, 27]. Quantitative ultrasonographic assessment of anterior translation of the glenohumeral joint was first reported in 1999 [13], and other researchers followed this standard ultrasonographic technique [10, 26, 27]. The current standard, quantitative ultrasonographic technique claims to be able to assess the distance between the humeral head and glenoid from the anterolateral aspect of the shoulder using three landmarks: coracoid process, glenoid, and humeral head [13, 26, 27].…”

“…The difference of the distance before and after applying an anterior load is used to measure anterior translation. This standard ultrasonographic technique has sufficient intra‐observer repeatability (intra‐class correlation coefficient [ICC], 0.85–0.96) [26, 27]. However, inter‐observer repeatability is reported as poor to moderate (ICC, 0.31–0.75), possibly arising from the difficulty of visualizing the glenoid due to the acoustic shadow created by the coracoid process [26].…”

Purpose Since poor repeatability of the load and shift test using a grading scale has been reported, an objective and quantitative method to assess anterior translation should be established to assess glenohumeral joint function. The purpose of this study was to assess the accuracy and repeatability of the ultrasonographic techniques to quantify anterior translation of the glenohumeral joint. Methods Eight fresh-frozen cadaveric shoulders were used. For the standard technique, the ultrasound transducer was positioned on the anterolateral aspect of the shoulder viewing the coracoid process, glenoid, and humeral head. For the revised technique, the transducer was positioned on the anterior aspect of the shoulder, perpendicular to the scapular plane, viewing the conjoint tendon, glenoid, and humeral head. During the load and shift test, the distance between anterior edges of the glenoid and the humeral head was measured. The diference between distances before and after applying an anterior load was calculated as an anterior translation and compared with the anterior translation assessed using a motion tracking system. The repeatability and accuracy of both techniques were analyzed statistically. Results Intra-and inter-observer repeatability was good-excellent for both ultrasonographic techniques (ICC, 0.889-0.998). The revised technique achieved a stronger correlation to the anterior translations obtained using the motion tracking system (R = 0.810-0.913, p < 0.001) than the standard technique (R = 0.619-0.806, p < 0.001). Conclusion Better accuracy and repeatability was found in the revised technique than the standard technique. The revised technique will be useful to determine the individual laxity and modify the treatment plan and return-to-sports protocol. Level of evidence III.
