What is Shoulder dislocation?
This is an injury where the upper arm bone (humerus) pops out of the cup-shaped socket at the shoulder joint, which is part of the shoulder blade. The shoulder, being the most mobile body joint, is prone to dislocation. There are cases of a partial as well as complete dislocation, both causing pain and instability in the shoulder.
When the head of the humerus dislocates, the socket bone (glenoid) and the ligaments in front of the shoulder are also injured. Shoulder dislocation types depends on the direction of dislocation of the ball:
What is Recurrent Shoulder Dislocation?
In this condition, the patient’s shoulder dislocations take on a recurrent nature, and they are said to have an Unstable Shoulder or Shoulder Instability.
The shoulder joint of a potentially unstable joint will have a wider circumference than the socket or glenoid and also shallow. The stability of the shoulder depends on the neighboring soft tissues like labrum, capsule and ligaments.
The disruption of the labrum, capsule and the ligaments in the front of the shoulder is called the Bankart’s Lesion. When the head of the humerus lies over the edge of the glenoid and causes an indentation on the ball, then it’s called Hill-Sach Lesion.
This can happen after:
The doctor performs a complete physical evaluation with study of the patient’s medical history. The shoulder’s looseness or laxity of the shoulder joint can be further diagnosed from the following tests:
The treatment options can be broadly classified as:
Surgical Treatment: This is done to repair the torn ligaments and the different procedures are:
