What is Scapulothoracic dissociation?
Scapulothoracic dissociation is a rare injury involving separation of scapula from the thorax along with the upper extremity. Majority of the patients have concomitant neurovascular injury and the prognosis is uniformly poor in such cases.
How is Scapulothoracic dissociation diagnosed?
The diagnosis of scapulothoracic dissociation can be made on an AP radiograph taken with the extremity not rotated by comparing distance from the medial border of the scapula with the spinous processes between the affected (long arrow) and unaffected (short arrow) sides.
Can the scapula dislocate?
Isolated dislocation of the scapula is a rare entity encountered in the emergency department. Two mechanisms have been proposed, a distraction injury to the arm or direct trauma to the posterior scapula. With blunt trauma, a search for adjacent injuries should be performed.
What is Scapulothoracic dysfunction?
Scapulothoracic dyskinesis is a rare condition characterized by abnormal scapula motion leading to shoulder impingement and dysfunction.
How is Glenopolar angle measured?
Measuring glenopolar angle (GPA) (A) by measuring the angle between the line connecting the upper and lower poles of the glenoid and the line connecting the upper pole of the glenoid with the inferior scapular angle.
Does a fractured scapula require surgery?
Most fractures of the scapula can be treated without surgery. Treatment involves immobilization with a sling or a shoulder immobilizer, icing and pain medications. The sling is usually kept for comfort for the first two weeks with subsequent increase of the shoulder’s range of motion.
What causes a floating shoulder?
Ipsilateral scapular neck and clavicular shaft fractures comprise the so-called “floating shoulder”. This rare injury, which is, in general, caused by a high-energy trauma, is perceived to be an unstable injury with the considerable risk of significant displacement of scapular neck and/or the clavicular fracture.
What is a floating collarbone?
Introduction. The ‘floating clavicle’ or dislocation of both ends of the clavicle is an extremely rare injury resulting from high-energy trauma. This injury was first described by Porral in 1831.
