Avulsion of capsulolabral complex is seen from which part of glenoid in bankarts lesion?
**Core Concept**
The Bankart lesion is a specific type of injury to the anterior glenohumeral joint capsule, characterized by the avulsion of the capsulolabral complex from the glenoid. This occurs due to anterior dislocation of the shoulder joint, resulting in a tear of the anterior labrum and the associated capsule.
**Why the Correct Answer is Right**
The correct answer is related to the specific location of the glenoid where the capsulolabral complex is avulsed. In a Bankart lesion, the anterior inferior part of the glenoid is involved. This is because the anterior labrum is most commonly torn from its attachment to the anterior inferior labral recess of the glenoid. The anterior inferior part of the glenoid provides a weak point in the joint capsule, making it susceptible to injury during anterior dislocation.
**Why Each Wrong Option is Incorrect**
**Option A:** This is incorrect because the posterior part of the glenoid is not typically involved in a Bankart lesion. The posterior labrum is generally more stable and less prone to injury.
**Option B:** This is incorrect because the superior part of the glenoid is not characteristically involved in a Bankart lesion. The superior labrum is more commonly associated with superior labral tears, also known as SLAP lesions.
**Option C:** This is incorrect because the posterior inferior part of the glenoid is not typically involved in a Bankart lesion. While posterior dislocations can occur, the posterior labrum is generally more stable and less prone to injury.
**Clinical Pearl / High-Yield Fact**
A key aspect of diagnosing a Bankart lesion is identifying the specific location of the capsulolabral avulsion on an arthroscopic examination or MRI. This is essential for determining the optimal treatment approach, which may involve arthroscopic or open repair of the injured labrum and capsule.
**Correct Answer:** A. Anterior inferior part of the glenoid.
