Background

  • Most frequently ruptures 2-6cm above calcaneus (where blood supply is weakest)
  • Typical patient is 30-50yr old man who participates in strenuous activities on occasional basis
  • Quinoloneassociated rupture occurs in only 12 per 100,000 treatment episodes, and risk may be equivalent to oral steroids or non-quinolone antibiotics [1]

Clinical Features

  • Sudden, severe pain typically with rapid acceleration or pivoting
  • May hear a "pop"
  • Inability to run, stand on toes, or climb stairs
  • Palpable defect in Achilles tendon 2-6cm proximal to calcaneus (SN 73% and SP 89% for partial tear)
  • 20-30% of ruptures will have some amount of active plantar flexion or be able to walk
  • Thompson test (SN 96% and SP 93%)
    • Lay patient prone with knee bent at 90°
    • In normal pt, squeezing calf results in plantarflexion

Differential Diagnosis

Calf pain

Evaluation

Ultrasound of Achilles tendon rupture, discontinuity shown by red bar. Plain film shows no fracture or avulsion.

Management

  • Rest, ice, elevation
  • Non-weightbearing
  • Short leg posterior splint with ankle slightly plantarflexed

Disposition

  • Outpatient with ortho referral
