Document Summary

Bpk 241 gh joint dislocation - textbook reading: describe the etiology of a gh joint subluxation & dislocation. Excessive translation humeral head w/o complete joint separation. Forces humeral heads out of socket past glenoid labrum then under coracoid process. Detached labrum/capsule can be permanent anterior defect on labrum = bankart lesion. Another defect posterior lateral aspect humeral = hill sachs lesion. Caused by compression cancellous bones of humerus against anterior glenoid rim. Another defect = superior labrum anterior/posterior (slap) Caused by injury superior aspect of labrum. Additional problems if humerus in contact & injures brachial nerves/vessels. Forced adduction / ir or fall on extended/ir arm. Tears posterior glenoid labrum are common. Fractures lesser tuberosity may occur as subscapularis tendon avulsed it attachment. Reverse hill sachs lesion defect can occur anterior medial portion of humeral head: describe the ssx of the anterior/posterior gh dislocation. Palpation axilla = prominence of humeral head. Can not touch other shoulder with injured arm.
