Resultant damage to the spinal cord may arise from direct pressure or may follow vascular impairment. The onset is usually gradual. Trauma may or may not predispose to the development of symptoms.

CLINICAL FEATURES Radiculopathy

Pain: A sharp stabbing pain, worse on coughing, may be superimposed on a more constant deep ache radiating over the shoulders and down the arm. Paraesthesia: Numbness or tingling follows a nerve root distribution.

Root signs:

- Sensory loss, i.e. pin prick deficit in the appropriate dermatomal distribution.

- Muscle (l.tn.n.) weakness and wasting in appropriate muscle groups, e.g. C5, C6 . . . biceps, deltoid: C7 . . . triceps.

- Reflex impairmentlloss, e.g. C5, 6 . . . biceps, supinator jerk: C7 . . . triceps jerk.

- Trophic change: In long-standing root compression, skin becomes dry, scaly, inelastic, blue and cold.
