Diagnosis of exclusion
Patients with possible trauma and/or fall…
Yield possibility of fracture
When you suspect fracture, what are the possible observations in the pt’s PE?
Unusual head carriage, careful palpation of cervical SP, percussion of SP of C2 &C7, severely restricted active ROM.
When you suspect fracture, what is a must do ?
X-ray of the pt’s complete cervical spine
When you suspect fracture, what should you avoid ?
Passive motion testing
When does percussive pain present?
Fracture, Tumor, Osteomyelitis, Infectious Discitis, Facet Joint Synovitis
What are some red flags in a pt with facet dislocation?

Compression of Spinal Cord
What symptoms will a pt with a herniated cervical disc present?
Neck pain which radiates into the shoulder, arm, forearm, wrist or hand
Describe the history of a pt with a herniated cervical disc due to trauma?
Presence of Pain which radiates into a dermatomal distribution. Numbness or Paresthesias in a Dermatomal Distribution
Describe the PE of a pt with a herniated cervical disc due to trauma?
Observe – May be abnormal head carriage and Loss or reversal of Cervical Lordosis. Palpate – Tenderness and muscle spasm at the level of the herniated disc
Describe the PE of a pt with a herniated cervical disc due to trauma? #2
Active ROM restricted in Flexion, may be restricted in other directions as well. Valsalva Test reproduces radicular pain.
Describe the PE of a pt with a herniated cervical disc due to trauma? #3
Flexion/Compression Test reproduces pain in nerve root distribution. Lhermitte Sign may be present
Valsalva Test
Reproduces the symptoms of any space occupying lesion within the spinal canal
Cervical Compression Test
Exert a downward (vertically) force in pt’s head. (perform only if valsalva is negative)
Distraction Test
With one hand in the pt’s occiputand the other under the pt’s chin, exert an upward force.
Lhermitte Sign
Electrical Shock Paresthesia down back, arms, legs with flexion of the neck. Occurs with any cause of spinal cord compression and with many causes of spinal cord inflammation
