Tests and diagnosis

By Mayo Clinic Staff

Besides physically examining your shoulder, your doctor may order the following tests:

  • X-ray. An X-ray of your shoulder joint will show the dislocation and may reveal broken bones or other damage to your shoulder joint.
  • MRI. Magnetic resonance imaging (MRI) uses a magnetic field to create cross-sectional images of the body. These images help your doctor assess damage to the soft tissue structures around your shoulder joint.
  • Electromyography (EMG). An EMG is a procedure that measures the electrical discharges produced in your muscles. An instrument records the electrical activity in your muscle at rest and as you contract the muscle. Analyzing the electrical signals may help your doctor evaluate nerve damage caused by severe or repeated shoulder dislocation.
