Bankart Lesion: Shoulder Injury and Treatment

Overview

A Bankart lesion is a specific injury to the shoulder joint, involving the anterior (inferior) glenoid labrum. It is commonly associated with anterior shoulder dislocations.

Pathophysiology

The Bankart lesion occurs when:

• The anterior part of the glenoid labrum is injured.
• A pocket forms at the front of the glenoid, allowing the humeral head to dislocate into it.

This condition often leads to recurrent shoulder dislocations.

Association with Hill-Sachs Lesion

• It is frequently accompanied by a Hill-Sachs lesion, which is damage to the posterior humeral head.
• This combination of injuries is indicative of severe shoulder instability.

Treatment and Surgery

Indications for surgery include:

• Recurrent shoulder dislocations
• Persistent pain or instability after shoulder dislocation

Surgical options may involve:

• Arthroscopic repair
• Reconstruction of the labrum
• Addressing any associated fractures

Bony Bankart Lesion

• A bony Bankart lesion includes a fracture of the anterior-inferior glenoid cavity of the scapula bone.
• Treatment of a bony Bankart lesion often requires more complex surgical procedures.

Historical Context

• The Bankart lesion is named after English orthopedic surgeon Arthur Sydney Blundell Bankart (1879–1951), who first described it.

Epidemiology and Risk Factors

• Common in younger individuals and athletes involved in contact sports.
• Risk factors include previous shoulder dislocations and ligamentous laxity.
