Achilles tendon rupture, Causes, Signs and Symptoms, Diagnosis and Treatment

Achilles tendon rupture is when the Achilles tendon, at the back of the ankle, breaks. Symptoms include the sudden onset of sharp pain in the heel. A snapping sound may be heard as the tendon breaks and walking becomes difficult.

Rupture typically occurs as a result of a sudden bending up of the foot when the calf muscle is engaged, direct trauma, or long-standing tendonitis. Other risk factors include the use of fluoroquinolones, a significant change in exercise, rheumatoid arthritis, gout, or corticosteroid use.Diagnosis is typically based on symptoms and examination and supported by medical imaging.

Prevention may include stretching before activity.Treatment may be by surgery or casting with the toes somewhat pointed down. Relatively rapid return to weight bearing (within 4 weeks) appears okay.The risk of re-rupture is about 25% with casting. If appropriate treatment does not occur within 4 weeks of the injury outcomes are not as good.
