Shoulder Separation vs Dislocation: What’s the Difference?
Shoulder separations are often confused with shoulder dislocations. However, there are significant differences between these two injuries - including how orthopaedic physicians treat them.
Understanding the differences between these conditions and the shoulder's complex nature can help explain your diagnosis and treatment options.
What is a Shoulder Dislocation?
When a shoulder is dislocated, the top of the arm bone pops out of the shoulder blade's socket. Usually, shoulder dislocations occur when the arm is extended overhead and behind the body, much like the cocking phase of throwing. In this position, an external force pushing the lower arm can cause the shoulder to lever out of the socket.
Symptoms of a shoulder dislocation are:
Extreme pain with limited mobility
Abnormal positioning of the arm or shoulder
Deformity below the shoulder
Shoulder dislocation is treated by moving the bone back into place, which can be done on the scene of the injury by an athletic trainer or at an orthopaedic clinic. Early surgery may be recommended to repair the torn ligaments, restore stability, and reduce the likelihood of a second dislocation.
How to Know if You Have a Shoulder Separation?
The AC shoulder joint is where the upper section of the scapula (acromion) meets the collarbone. In a shoulder separation, the ligaments that connect the AC joint are injured, causing the acromion to separate from the collarbone.
Symptoms of a shoulder separation include:
Pain
Bruising or swelling near the joint
Deformation on top of the shoulder
Shoulder separations are typically the result of a sudden, forceful impact - such as a fall - or a sharp twist of the arm. These injuries are graded (Type I - VI) based on the severity of the separation, ranging from a ligament sprain to a complete tear.
Treating a shoulder separation is not “one-size-fits-all.” Factors that can impact shoulder separation treatment include:
Age
Activity level
Severity of separation
In most cases, shoulder separations can be treated nonsurgically with ice, rest, anti-inflammatory medications, and physical therapy. However, in cases where severe ligament damage is present (usually seen in Types IV-VI), surgical intervention might be necessary.
