BACKGROUND A symptomatic os acromiale can lead to impingement syndrome and rotator cuff tendinopathy. An acromion fracture is often part of a more complex scapular trauma that needs stabilisation. METHODS We developed a new technique using a three-dimensional (3D) model and a distal clavicle reconstruction plate to treat os acromiale and acromion fractures. Our hypothesis was that such an app...

We report the case of a patient with a long standing clinical history of subacromial impingement, in which plain radiographs and CT-scan revealed a well-circumscribed lucent lesion expanding the undersurface of the acromion. MRI showed the subacromial fat to be completely obliterated and the infraspinatus tendon deformed due to compression by a mass localised at the acromion. The acromial lesio...

displaced fracture of the acromion without associated shoulder injury occurs rarely. a 31-year-old gentleman presented with an isolated acromion fracture resulting from a direct trauma to the top of his left shoulder. open reduction and internal fixation using multiple pins was performed and the fracture was closed without complications. the patient achieved excellent shoulder function and rank...

Purpose and hypothesis: Acromion spur is the extrinsic factor for impingement syndrome and rotator cuff tear. The Rockwood tilt view can be used to evaluate prominence of the anterior acromion, however no study has shown the correlation of findings between the Rockwood tilt view and the arthroscopic finding. METHODS We developed the arthroscopic classification of acromion spur as type 1 flat ...

OBJECTIVE To investigate the technical feasibility of harvesting a vascularized bone graft from the acromion pedicled on the acromial branch. BACKGROUND Complex fractures of the proximal humerus may result in partial or total avascular necrosis of the head fragment. Treatment of avascular necrosis of the humeral head is dependent upon the stage of disease as well as the dimension and location...

PURPOSE To evaluate the effect of arthroscopic acromioplasty on the anterior deltoid origin. TYPE OF STUDY In vitro cadaveric histologic study. METHODS We performed a histologic evaluation of the anterior aspect of 15 acromions, the parameters of the anatomy of the anterior acromion, including the deltoid origin, and the morphology of the acromion. A simulated arthroscopic acromioplasty was...

The acromial tracker is used to measure scapular rotations during dynamic movements. The method has low accuracy in high elevations and is sensitive to its attachment location on the acromion. The aim of this study was to investigate the effect of the attachment position and shoulder orientation during calibration on the tracker accuracy. The tracker was attached to one of three positions: near...
