Shoulder Dislocation Treatment Singapore

Shoulder dislocation occurs when the ball of the upper arm bone (humerus) is displaced from its normal position in the socket of the shoulder blade (scapula). This condition can result in pain, unsteadiness, and limited movement of the shoulder joint. The shoulder, being the most mobile joint in the human body, is particularly susceptible to dislocation due to its wide range of motion.

The condition can further be classified as either partial (subluxation) where the head of the humerus is partly out of the socket, or complete where it is completely out of the socket. Both types can cause damage to the surrounding muscles, ligaments, nerves, and blood vessels.

Understanding the causes of shoulder dislocation is important in both prevention and treatment strategies.

• Trauma
  The most common cause of a shoulder dislocation is a traumatic injury. This can include falls, particularly onto an outstretched hand, sports injuries, and direct blows to the shoulder area. High-impact activities or accidents, such as motor vehicle accidents, can also result in dislocation.
• Sports Injuries
  Athletes, especially those involved in contact sports like football, rugby, or martial arts, and sports that involve falls, such as skiing or gymnastics, are at a higher risk of experiencing shoulder dislocations.
• Weakness or Instability of the Shoulder Joint
  Some individuals have naturally loose ligaments, leading to increased joint flexibility and instability. This condition, known as joint hypermobility, can increase the risk of dislocation, even from minor injuries or movements.
• Falls
  Falling onto an outstretched arm or directly onto the shoulder can forcefully push the arm bone out of its socket, leading to dislocation. This is particularly common in older adults, who may be more prone to falls.
• Repetitive Strain
  Overusing the shoulder joint in repetitive motions, especially in overhead activities, can stretch or tear the ligaments and muscles around the shoulder, increasing the risk of dislocation.
• Genetic Factors
  There may be a genetic predisposition in some individuals that makes them more susceptible to shoulder dislocations, particularly in cases of joint hypermobility or connective tissue disorders.

Diagnosing a shoulder dislocation involves several key steps:

• Physical Examination: Initially, the doctor conducts a physical examination to assess the shoulder’s appearance, checking for deformity, swelling, and signs of muscle, tendon, or ligament injury.
• Medical History Review: The doctor will review the patient’s medical history, focusing on the injury’s circumstances, any previous shoulder issues, and overall joint health.
• Imaging Tests:
  • X-rays are crucial to confirm the dislocation and identify any related fractures.
  • MRI Scans might be used to evaluate soft tissue damage, crucial for planning treatment.
  • CT Scans provide detailed images, particularly useful for complex cases or to assess bone positioning.
• Neurovascular Assessment: An examination of the nerve and blood supply to the arm and hand is performed to check for any damage caused by the dislocation.

In more severe cases, surgical interventions may be necessary to treat a shoulder dislocation.

• Arthroscopic Surgery
  This is a minimally invasive surgery used to repair or tighten the torn or stretched ligaments that hold the shoulder joint in place. Through small incisions, a camera and surgical tools are inserted to perform the procedure, resulting in less pain and a quicker recovery time compared to open surgery.
• Open Surgery
  In cases where there is severe damage or complex dislocations, open surgery may be necessary. This involves a larger incision to access and repair the shoulder structures. Open surgery may be more appropriate for individuals with extensive soft tissue damage or bone fractures.
• Latarjet Procedure
  This procedure is used in cases of severe instability or when there is bone loss from the socket. It involves transferring a small piece of bone with an attached tendon to the shoulder socket to create a more stable joint.

Preventing a shoulder dislocation is as important as treating one. These measures include:

• Strengthening Exercises: Regular exercises to strengthen the shoulder muscles can provide better stability to the joint. This is especially crucial for athletes and others engaging in shoulder-stressing activities.
• Proper Technique in Sports and Exercise: Using the correct technique during sports and physical activities can reduce the risk of shoulder injury. This includes proper form when lifting weights, throwing, or performing overhead motions.
• Avoiding High-Risk Activities: For individuals with a history of shoulder dislocation, avoiding or modifying high-risk activities and sports that increase the likelihood of a dislocation is advisable.
• Protective Gear: Wearing protective gear during sports or activities that pose a risk to the shoulder can help prevent injury. This includes padding, braces, or other support devices designed for shoulder protection.
• Ergonomic Workplace Adjustments: For those whose work involves repetitive shoulder movements or heavy lifting, making ergonomic adjustments can help reduce strain on the shoulder joint.
