☘ Why is the shoulder prone to repeated dislocations after one dislocation? Like the hip joint, the shoulder is also part of ball and socket joints 🌷 In this way, the bone head is spherical in shape and moves inside a cavity The difference is here, unlike the hip, where the head of the femur is located inside a deep bony cavity called the acetabulum, the head of the humerus is located in front of a deep concave surface called the glenoid. On the other hand, the size ratio of these two surfaces is such that only a quarter of the head of the humerus is placed against the glenoid In order to increase the depth of the glenoid, a fibrocartilaginous tissue surrounds its edge, which is called the labrum.

Among all the joints of the body, the shoulder has the highest range of motion and this has reduced its strength. During dislocation of the head of the humerus from inside the glenoid, it is possible that a part of its margin is torn off by the head hitting the edge of the glenoid and creating a defect in its edge. 🌷 This torn piece is called Benkart damage After creating this defect in the glenoid environment, every time the head of the arm is placed in front of it, it slips out of the cavity and dislocation occurs. 🌷 If the patient takes treatment in the initial stages, this torn piece will be fixed in its place and recovery will be achieved. But delay in treatment and repeated dislocations make this defect bigger and more damage occurs and treatment becomes difficult.
