Anterior shoulder dislocation while carrying a frail elder. A dislocated shoulder is a condition in which the head of the humerus is detached from the glenoid fossa. [2] Symptoms include shoulder pain and instability. [2] Complications may include a Bankart lesion, Hill-Sachs lesion, rotator cuff tear, or injury to the axillary nerve. [1]
Anterior shoulder dislocation often is a result of a blow to the shoulder while the arm is in an abducted position. In younger people, these dislocation events are most commonly associated with fractures on the humerus and/or glenoid and can lead to recurrent instability.
Dislocations are commonly caused by sudden trauma to the joint like during a car accident or fall. A joint dislocation can damage the surrounding ligaments, tendons, muscles, and nerves. [2] Dislocations can occur in any major joint (shoulder, knees, hips) or minor joint (toes, fingers). The most common joint dislocation is a shoulder ...
The shoulder joint is the most frequently dislocated major joint of the body. In a typical case of a dislocated shoulder, a strong force that pulls the shoulder outward (abduction) or extreme rotation of the joint pops the ball of the humerus out of the shoulder socket.
A SLAP tear or SLAP lesion is an injury to the superior glenoid labrum (fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade) that initiates in the back of the labrum and stretches toward the front into the attachment point of the long head of the biceps tendon.
Its presence is a specific sign of dislocation and can thus be used as an indicator that dislocation has occurred even if the joint has regained its normal alignment. Large, engaging Hill-Sachs fractures can contribute to shoulder instability and will often cause painful clicking, catching, or popping.
Shoulder anatomy, front view Shoulder anatomy, back view The rotator cuff is an anatomical term given to the group of four muscles and their tendons that act to stabilize the shoulder. [ 3 ] These muscles are the supraspinatus , infraspinatus , teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during ...
Shoulder reduction is the process of returning the shoulder to its normal position following a shoulder dislocation.Normally, closed reduction, in which the relationship of bone and joint is manipulated externally without surgical intervention, is used.
