“…After primary dislocation, recurrence may result from less violent trauma; from dislocation to dislocation, the force implicated diminishes [48]. Thus, young subjects with unstable shoulder run an elevated daily risk of dislocation: while dressing, washing, or in their sleep.…”

A 26-year-old Olympic wrestling athlete presented with a pectoralis major muscle injury, glenohumeral instability and acromioclavicular joint dislocation separately. The patient underwent surgical treatment to repair these injuries. The pectoralis major muscle was reconstructed with a semitendinosus tendon graft using the endobutton technique, as described by Pochiniet al.Treatment of the traumatic anterior instability was performed using the technique described by Bristow-Latarjet, and the acromioclavicular joint dislocation was repaired using the modified technique of Weaver-Dunn with the aid of an anchor. The athlete exhibited a rapid recovery and could return to normal activities 6 months after surgery. At present, 18 months postoperatively, the patient is asymptomatic.

“…The arm orientation has been recognized as a substantial factor of the shoulder dislocation from clinical experiences. However, the previous cadaveric studies of the dislocated cases failed to clarify precise mechanisms of dislocation 1) . During the competition of rugby, which is one of the most popular collision sports worldwide, the shoulder dislocation develops frequently by tackling, so that the study of rugby would provide useful information to reveal the mechanisms of shoulder dislocation in a real-world settings [2][3][4][5] .…”

To investigate the effects of head position on scapular orientation in a posture of simulated rugby tackling. Design: Laboratory experimental study.Methods: Twenty-nine healthy young men lay on the edge of a wooden rigid bed in the prone position with their dominant arm free. The experimental arm movement task was conducted in four head positions (2 neck bending x 2 neck rotation) with maximum ranges of direction: the dominant arm was rotated from an intermediate position to maximum external rotation at 90° shoulder abduction with 90° elbow flexion while maintaining each neck position. During the tasks, dynamic scapular orientations were measured with an electromagnetic sensor system.Results: In total, 348 experimental trials were included in the analyses. Two-way repeated-measures analysis of variance demonstrated that the direction of neck bending and the side of neck rotation relative to the arm movement significantly affected the scapular orientation. The scapular tilting angle was significant during neck rotation ipsilateral to the arm movement (mean difference, 11°). The scapular upward rotation angle was higher during neck rotation contralateral than ipsilateral rotation to the arm movement (mean difference, 2.5°) regardless of the neck bending position. The scapular external rotation angle was significant during neck rotation ipsilateral to the arm movement (mean difference, 5.5°). Conclusions:The neck position affects the scapular orientation in the prone position. Neck flexion with rotation contralateral to the arm movement represents an anteriorly tilted and internally rotated scapula orientation, which may increase the risk of shoulder injury such as dislocation.
