Important blood vessels and nerves lie close to the bone, especially around the major joints. Assess circulation, motor and sensory function (CMS) as part of the detailed physical exam.

Circulation	Palpate the pulse distal to the point of injury and check skin color and/or capillary refill time.
Motor	Evaluate motor function by asking the patient to wiggle fingers or toes.
Sensation	Assess sensation and the patient’s ability to sense light touch by asking the patient to identify which digit you are touching.

If you suspect that a joint is dislocated, you should assess distal nerve and vascular function by checking CMS. Repeat every 5 to 10 minutes and document the results of your assessment.

If a limb has lost circulation, motor or sensory function, attempt to reposition the dislocated joint then reassess CMS and note any changes. (Discontinue repositioning if the patient experiences increased pain or crepitus.)
