Understanding and Managing Anterior Shoulder Dislocations: A Comprehensive Guide to Recovery

The shoulder is a marvel of human biomechanics. As the most mobile joint in the body, it allows us to reach, lift, and throw with incredible range. However, this mobility comes at a cost: stability. The glenohumeral joint is often described as a "golf ball on a tee," making it particularly susceptible to injury. Among these injuries, the anterior shoulder dislocation is the most common, accounting for approximately 95% of all shoulder dislocations.

At Destiny Health, we see many clients, from weekend warriors to elite athletes, struggling with the physical and psychological aftermath of a shoulder "pop out." This guide explores the latest evidence-based approaches to managing these injuries, from the moment of impact to the long-term prevention of recurrence.

The Anatomy of the Injury

In an anterior dislocation, the head of the humerus (the ball) is forced out of the glenoid fossa (the socket) in a forward direction. This usually occurs when the arm is in a position of "abduction and external rotation" - think of the "high-five" position or the cocking phase of a throwing motion.

When the humerus is forced forward, it doesn't just slip out; it often damages the structures designed to keep it in place:

• The Labrum: A fibrocartilage ring that deepens the socket. A tear here is known as a Bankart lesion.

• The Capsule: The fibrous sleeve surrounding the joint.

• The Bone: A forceful dislocation can cause a "divot" in the back of the humeral head, known as a Hill-Sachs lesion, or a fracture of the glenoid rim.

Recent research highlights that the presence of these "bony lesions" is one of the most significant predictors of whether a shoulder will dislocate again (Di Giacomo et al., 2020).

Acute Management: The First 72 Hours

If you suspect a dislocation, the first priority is reduction: putting the joint back in its socket. This should always be performed by a medical professional. "Popping it back in" yourself or having a friend do it can result in fractures or nerve damage.

The Myth of Long-term Immobilisation

Historically, patients were told to keep their arm in a sling for six weeks. However, cutting-edge Cochrane reviews and recent trials have challenged this. Current evidence suggests that prolonged immobilisation does not reduce the rate of recurrence compared to early protected movement (Patterson et al., 2010).

Modern protocols now favour:

1. Short-term comfort: Wearing a sling for only 1–2 weeks to manage pain.

2. Early mobilisation: Beginning gentle range-of-motion exercises as soon as pain allows.

The Rehabilitation Journey: A Three-Phase Approach

Effective rehabilitation is not just about "getting strong." It’s about restoring the complex neuromuscular patterns that keep the ball centred in the socket. It's crucial to remember that your specific rehabilitation plan will be tailored by your physiotherapist at Destiny Health based on the severity of your injury and your individual needs.

Phase 1: Protection and Gentle Activation (Weeks 0-4)

In the initial weeks, the primary goals are to reduce pain and inflammation, protect the healing tissues, and gently restore basic, pain-free range of motion. We also begin to activate the deep stabilising muscles without stressing the joint.

Key Goals:

• Pain and swelling management

• Protect healing structures

• Restore gentle, pain-free passive and active-assisted range of motion

• Begin gentle isometric contractions of the rotator cuff and scapular muscles

Exercise Examples:

1. Pendulum Swings:

• How to: Lean forward, supporting your weight on your uninjured arm on a table. Let your injured arm hang freely. Gently swing it forwards and backwards, side to side, and in small circles. Keep the movement minimal and pain-free.

• Why: These passive movements help to gently mobilise the joint, reduce stiffness, and promote blood flow without active muscle contraction of the injured shoulder.

2. Scapular Retractions (Squeezing Shoulder Blades):

• How to: Sit or stand tall. Gently squeeze your shoulder blades together and down, as if trying to hold a pencil between them. Hold for 3-5 seconds and release. Ensure your shoulders don't shrug up towards your ears.

• Why: This activates the muscles that control your shoulder blade (rhomboids, middle trapezius), which are crucial for providing a stable base for your arm movements.

Phase 2: Strengthening and Restoring Full Range of Motion (Weeks 4-12)

Once basic movement is pain-free and control of the scapula is established, we progressively increase the load on the rotator cuff and surrounding shoulder muscles. The focus shifts to restoring full active range of motion and building foundational strength.

Key Goals:

• Achieve full, pain-free active range of motion

• Begin progressive strengthening of rotator cuff and periscapular muscles

• Improve postural control and endurance

• Introduce gentle core stability exercises

Exercise Examples:

1. Isometric External Rotation:

• How to: Stand with your injured side next to a wall. Bend your elbow to 90 degrees and place the back of your hand against the wall. Gently push your hand into the wall without moving your arm. Hold for 5-10 seconds.

• Why: This strengthens the external rotator muscles of the rotator cuff (infraspinatus and teres minor) without putting excessive strain on the healing joint.

2. Theraband Internal Rotation:

• How to: Anchor a resistance band at waist height. Stand with your injured side facing away from the anchor point, holding the band with your elbow bent at 90 degrees and tucked into your side. Pull the band across your body, bringing your hand towards your stomach. Slowly return to the start.

• Why: This strengthens the internal rotator muscles (subscapularis), which are vital for overall shoulder stability and balanced strength around the joint.

Phase 3: Proprioception, Power, and Return to Activity (Weeks 12+)

This is the most overlooked phase, focusing on advanced strengthening, power development, and retraining the shoulder's ability to react quickly and appropriately to unexpected movements. This is critical for preventing re-injury, especially for those returning to sport or physically demanding jobs.

Key Goals:

• Restore high-level strength and endurance

• Improve proprioception and neuromuscular control (the brain's awareness of the joint position)

• Develop power and speed for functional and sport-specific movements

• Gradual and safe return to desired activities

Exercise Examples:

1. Dynamic Stabilisation with a Ball on a Wall:

• How to: Stand facing a wall, holding a small ball (like a tennis ball) against the wall with your injured arm. Gently roll the ball up, down, and in circles, keeping constant pressure on the ball. Progress by moving further from the wall or performing it with your eyes closed.

• Why: This exercise trains the shoulder's small stabilising muscles to react dynamically and rapidly to unpredictable forces, improving proprioception and neuromuscular control crucial for stability.

To Operate or Not? The Surgical Debate

One of the most common questions we hear at Destiny Health is: "Do I need surgery?"

The answer has shifted significantly due to recent longitudinal studies. The decision is now based on a Risk of Recurrence profile.

The "High Risk" Candidate

You are more likely to be recommended for surgery (typically a Bankart Repair or a Latarjet procedure) if you:

• Are under the age of 25.

• Participate in contact sports (e.g., Rugby, AFL).

• Have significant "bone loss" (Hill-Sachs or glenoid fractures).

Research indicates that in young, active males, the recurrence rate after a first-time dislocation managed non-operatively can be as high as 70-90% (Hovelius et al., 2008). In these cases, early surgical intervention may be the most efficient path back to sport.

The "Conservative" Candidate

For older individuals or those with low-demand lifestyles, intensive physiotherapy is often just as effective as surgery. A landmark study published in the British Journal of Sports Medicine found no significant difference in long-term outcomes for certain patient groups between those who had surgery and those who completed a structured rehab programme (Knutsen et al., 2015).

Emerging Science: The Brain’s Role in Stability

Groundbreaking research in the field of Neuroplasticity suggests that chronic shoulder instability isn't just a "shoulder problem," it's a brain problem. When a joint dislocates, the motor cortex in the brain undergoes changes. The brain becomes "protective," often inhibiting certain muscles and over-activating others.

At Destiny Health, we incorporate "External Focus" cues during rehab. Instead of telling a patient to "contract your deltoid," we might ask them to "push the ball towards the wall." This engages the nervous system more effectively, leading to faster and more permanent gains in stability.

Long-term Prevention: Staying "In the Socket"

Recovery doesn't end when the pain stops. To prevent a recurrence, you must maintain "shoulder hygiene."

1. Consistent Rotator Cuff Conditioning: Treat it kind of like brushing your teeth (a frequent task), 10 minutes, three times a week, indefinitely.

2. Thoracic Mobility: If your upper back is stiff, your shoulder has to work harder to compensate.

3. Fatigue Management: Most dislocations happen at the end of a game or a long gym session when the stabilising muscles are tired. Listen to your body.
