The purpose of this study was to investigate supraspinatus tendon sonographic morphology in a population of young overhead athletes in correlation with main pathologic models of secondary shoulder impingement syndrome.
Between April and May 2004, 20 subjects (ten professional basketball players and ten non-athlete controls of the same age, weight and height ranges) underwent bilateral, standardised, sonographic sholulder examination to evaluate supraspinatus echotexture, supraspinatus and subacromial bursa thickness, subacromial space width (cutoff of 7 mm) and dynamic anterior impingement beneath the acromial margin.
All subjects were right handed. No symptomatic controls were found. Four players showed signs and symptoms of right atraumatic shoulder instability (two cases) or supraspinatus impingement with anterior pain (one right and one left shoulder). Subacromial space width was reduced in five right-dominant players' shoulders (three symptomatic and two asymptomatic) versus zero controls (p<0.05) and in eight players' shoulders versus zero controls on total shoulders (p<0.05). No other significant differences were observed between the two groups in sonographic parameters considered.
Despite the study limitations, ultrasonography (US) is able to detect subacromial space narrowing in young overhead athletes as early shoulder impingement sign, according to the continuum impingement-instability pathologic model.
本研究旨在调查年轻的过头运动运动员群体中冈上肌腱的超声形态，并将其与继发性肩峰撞击综合征的主要病理模型相关联。
2004年4月至5月期间，20名受试者（10名职业篮球运动员以及10名年龄、体重和身高范围相同的非运动员对照者）接受了双侧标准化肩部超声检查，以评估冈上肌回声纹理、冈上肌和肩峰下囊厚度、肩峰下间隙宽度（临界值为7毫米）以及肩峰边缘下方的动态前向撞击情况。
所有受试者均为右利手。未发现有症状的对照者。4名运动员出现了右侧非创伤性肩部不稳定（2例）或伴有前侧疼痛的冈上肌撞击（1例右侧和1例左侧肩部）的体征和症状。与0名对照者相比，5名右利手运动员的肩部肩峰下间隙宽度减小（其中3例有症状，2例无症状）（p<0.05）；与0名对照者相比，8名运动员的双侧肩部肩峰下间隙宽度减小（p<0.05）。在考虑的超声参数方面，两组之间未观察到其他显著差异。
尽管本研究存在局限性，但根据连续的撞击 - 不稳定病理模型，超声检查（US）能够检测到年轻的过头运动运动员肩峰下间隙变窄，作为早期肩部撞击的迹象。
