Diagnostic method | Based on symptoms and examination, supported by medical imaging[5] |
Differential diagnosis | Achilles tendinitis, ankle sprain, avulsion fracture of the calcaneus[5] |
Treatment | Casting or surgery[6][5] |
Frequency | 1 per 10,000 people per year[5] |
Achilles tendon rupture is when the Achilles tendon, at the back of the ankle, breaks.[5] Symptoms include the sudden onset of sharp pain in the heel.[3] A snapping sound may be heard as the tendon breaks and walking becomes difficult.[4]
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.[4][5] Other risk factors include the use of fluoroquinolones, a significant change in exercise, rheumatoid arthritis, gout, or corticosteroid use.[1][5] Diagnosis is typically based on symptoms and examination and supported by medical imaging.[5]
Prevention may include stretching before activity and gradual progression of exercise intensity.[4] Treatment may consist of surgical repair or conservative management.[6][2] Quick return to weight bearing (within 4 weeks) appears acceptable and is often recommended.[6][7] While surgery traditionally results in a small decrease in the risk of re-rupture, the risk of other complications is greater.[2] Non-surgical treatment is an alternative as there is supporting evidence that rerupture rates and satisfactory outcomes are comparable to surgery.[2] If appropriate treatment does not occur within 4 weeks of the injury outcomes are not as good.[8]
Achilles tendon rupture occurs in about 1 per 10,000 people per year.[5] Males are more commonly affected than females.[1] People in their 30s to 50s are most commonly affected.[5]
