Physical examination evaluates ankle stability, swelling, deformity, and extent of other injuries. Clinical rules are available to minimize use of x-rays, including Low Risk Ankle Rule (LRAR), Ottawa ankle rules, and two-part malleolar zone rules.
Management depends on the type, location, and severity of ankle injury and can range from modifying activity, ice, compression, and elevation (MICE mnemonic) to rest, wrapping, bracing, taping, physical therapy, and proprioceptive exercises for ankle sprain. Ankle fracture may be classified by the Salter-Harris scale, and management ranges from immobilization, bracing, splint, air cast, and tubular wrap, to surgical reduction, instrumentation, and casting.
