  1. Acute Achilles Tendon Rupture Paul Herickhoff, MD March 26, 2009

  2. Background • Largest, most powerful tendon in body • Formed by gastrocnemius and soleus • Incidence of rupture 18:100,000 • Incidence is increasing • As demonstrated by population based studies in Finland, Canada, Scotland and Sweden

  3. Presentation • Adults 40-50 y.o. primarily affected (M>F) • Athletic activities, usually with sudden starting or stopping • “Snap” in heel with pain, which may subside quickly

  4. Factors to consider • 25% of patients have previous symptoms of Achilles inflammation • Leppilahti et al. Clin Orthop 1998 • Associated conditions: • Ochronosis • Steroid use • Quinolones • Inflammatory arthritis

  5. Diagnosis • Weakness in plantarflexion • Gap in tendon • Positive Thompson test

  6. Imaging • X-rays • Indicated if fracture or avulsion fracture suspected • Ultrasound or MRI • Reveal tendon degeneration, if present

  7. Treatment • Non-operative versus operative treatment controversial • Several methods described for each

  8. Non-operative • Cast immobilization • Traditional recommendation is 8 weeks of immobilization • Wallace recommended patellar tendon bearing orthosis for weeks 4-8 • Functional brace with semi-rigid tape and polypropylene orthoses for duration of treatment also described • Rerupture rate 8-39% reported

  9. Operative • Open repair • Locking stitch, +/- augmentation with plantaris or mesh • Post-op care = Casting for 6-8 weeks • Risks: Infection (4-21%), Rerupture (1-5%)

  10. Operative • Percutaneous • Bunnell stitch • Weaker than open repair (Rerupture 0-17%) • Risk of sural nerve injury (0-13%) • Decreased infection risk

  11. Op vs. Non-op • Wong et al Am J Sports Med 2002 • Metanalysis 125 articles, 5370 patients • Wound complication (14.6 vs 0.5%) • Rerupture (1.5 perc,1.4 open vs 10.7%) • Complication rates lowest in open repair and early mobilization, highest in percutaneous repair and early mobilization

  12. Op vs. Non-op • Bhandari et al. Clin Orthop 2002 • More stringent inclusion criteria than Wong • 6 studies, 448 patients • Wound infection (5% vs 0%) • Rerupture (3% vs 13%)

  13. Risk Factors for Wound Complication • Bruggeman et al Clin Orthop 2004 and Pajala et al. JBJS 2002 • Age • Tobacco • Diabetes • Female gender • Steroid use • Treatment delay • Low energy injury (during ADL’s)

  14. Summary • Incidence of Achilles tendon rupture increasing • Operative repair associated with lower rerupture rate, but higher wound complication rate compared to non-op • Percutaneous repair has risk of nerve injury • Review risk factors before deciding treatment plan
