--As with most soft-tissue injuries, RICE (rest, ice, elevation) is likely the best immediate treatment. Application of an immobilizer might be useful. If a Zimmer immobilizer is not available, demonstration of a bulky Jones-type dressing might be appropriate here. Analgesics might also be useful. NSAIDs can be used, but may exacerbate bleeding if a surgical procedure is contemplated in the near term.

--Sprains are graded on the presence or absence of an end-point in the range of motion:
1st degree: There does not appear to be excessive laxity. The end-point is well-defined and appears to be around the limits of normal.
2nd degree: There is a moderate degree of laxity, but the end-point can be found upon provocation.
3rd degree: There is considerable laxity and the end-point, if present, is extremely abnormal.
