Posterior labrocapsular periosteal sleeve avulsion lesion

A posterior labrocapsular periosteal sleeve avulsion (or POLPSA) lesion occurs when trauma causes the posterior scapular periosteum and posterior labrum of the glenohumeral joint to strip off leading to a redundant recess.






Impingement of the humeral head onto the posterior labrum and capsule due to recurrent subluxation or posterior dislocation.
