Abstract
Traumatic posterior glenohumeral joint (GHJ) dislocation is a rare condition which can be missed if it is not suspected. Clinical presentation may be subtle, but limitation in range of motion in patient with acute trauma should warrant obtaining a thorough history, performing a comprehensive physical examination, and acquiring at least a 3-view plain radiography. Reduction can be achieved with a direct pressure to the posterior aspect of the humeral head.
Highlights
Plain radiography revealed posterior glenohumeral joint (GHJ) dislocation (Image 1). We reduced his posterior GHJ dislocation using direct pressure to the posterior aspect of his humeral head in a sitting position without any analgesics (Image 2 and Video)
Due to subtle clinical presentations, among the elderly with atraumatic etiology, and subtle signs on plain radiography, up to 80% of these dislocations are misdiagnosed for months.[1,2,3]
There is a gap in the literature on the management of acute traumatic posterior GHJ dislocations.[2 3]
Summary
CASE PRESENTATION A 44-year-old male presented at a ski clinic shortly after a fall directly onto his right shoulder while skiing He was unable to move his right arm due to pain. His past medical history was significant for right shoulder dislocation about 25 years earlier. He had an active lifestyle and denied experiencing any other shoulder injuries since On physical examination, he was holding his right arm in an adducted and internally rotated position. Plain radiography revealed posterior glenohumeral joint (GHJ) dislocation (Image 1). Right shoulder plain radiography reveals posterior glenohumeral dislocation (arrow) on AP (A) and scapular Y (B) views.
