Ankle
sprains are a common problem seen by primary care physicians, especially among teenagers and young adults. Most ankle
sprains are inversion
injuries to the lateral ankle ligaments, although high
sprains representing damage to the tibiofibular syndesmosis are becoming increasingly recognized. Physicians should apply the Ottawa ankle rules to determine whether radiography is needed. According to the Ottawa criteria, radiography is indicated if there is
pain in the malleolar or midfoot zone, and either bone tenderness over an area of potential fracture (i.e., lateral malleolus, medial malleolus, base of fifth metatarsal, or navicular bone) or an inability to bear weight for four steps immediately after the injury and in the emergency department or physician's office. Patients with ankle
sprain should use
cryotherapy for the first three to seven days to reduce
pain and improve recovery time. Patients should wear a lace-up ankle support or an air stirrup
brace combined with an
elastic compression wrap to reduce swelling and
pain, speed recovery, and protect the injured ligaments as they become more mobile.
Early mobilization speeds healing and reduces
pain more effectively than prolonged rest.
Pain control options for patients with ankle
sprain include nonsteroidal anti-inflammatory drugs,
acetaminophen, and mild
opioids. Because a previous ankle
sprain is the greatest risk factor for an acute ankle
sprain, recovering patients should be counseled on prevention strategies. Ankle
braces and supports, ankle taping, a focused neuromuscular training program, and regular sport-specific warm-up exercises can protect against
ankle injuries, and should be considered for patients returning to sports or other high-risk activities.
