The shoulder manifests as a severe droop, secondary to downward displacement of the scapula and humerus due to loss of the clavicular strut.
The inability to fixate the scapulae prevents full abduction of the arm and gives rise to a rather characteristic appearance around the shoulders when this movement is attempted.
Challenges were injected subcutaneously (s. c.) between the scapulae.
It was demonstrated that the girdle produces two independent degrees of freedom which characterize the motion of the scapula and are mostly rotatory.
Differs from all other stegosaurs in possessing parascapular spines that are at least twice the length of the scapulae.
Other features, less easily identified on ultrasound include hypoplastic scapulae, narrow iliac wings and a poorly ossified pubis.
The mechanism possesses a fixed base representing the torso and a movable platform representing the scapula holding the glenohumeral joint.
Glenohumeral subluxation, scapula resting position and scapula rotation after stroke: a noninvasive evaluation.
