A 32 years male with history of recurrent posterior dislocation of shoulder joint. which aspect in head of the hermerus likely to show the lesion
**Core Concept**
The question is testing the understanding of the anatomy and pathophysiology of recurrent posterior dislocation of the shoulder joint, specifically the involvement of the humeral head.
**Why the Correct Answer is Right**
Recurrent posterior dislocation of the shoulder joint is often associated with a specific type of lesion in the humeral head. The lesion is typically located on the posterior aspect of the humeral head, where the capsule and ligaments insert. This area is prone to injury due to the abnormal tracking of the humeral head during posterior dislocation. The lesion is thought to be a result of repetitive microtrauma, leading to chondral or bony changes in the affected area.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the lesion is typically not located on the anterior aspect of the humeral head.
* **Option B:** This option is incorrect because the lesion is not typically associated with the coracoid process or the acromion.
* **Option C:** This option is incorrect because the lesion is not typically located on the inferior aspect of the humeral head.
**Clinical Pearl / High-Yield Fact**
In cases of recurrent posterior dislocation of the shoulder joint, a specific type of lesion in the humeral head is often identified. This lesion is typically located on the posterior aspect of the humeral head and is thought to be a result of repetitive microtrauma.
**Correct Answer:** B. The bony Bankart lesion is a type of lesion that is often associated with recurrent posterior dislocation of the shoulder joint.
