Advances in biomechanics of posterior tibial tendon dysfunction and flatfoot deformity

Introduction

The objective of this presentation is to highlight the clinical and laboratory-based research related to posterior tibial tendon dysfunction (PTTD).

Methods and results

  • Defining the flatfoot: clinical, foot pressure, radiologic

  • Critical evaluation of flatfoot deformity: in vitro

  • How often does the flatfoot occur?

  • Normal arch development

  • Why is the flatfoot a problem?

  • Why does the flatfoot occur?

  • â—‹ 1. Effects of weightbearing [1]

  • â—‹ 2. Lost of static support [2]

  • â—‹ 3. Loss of dynamic support [3]

  • â—‹ 4. Anatomic predisposition

  • â—‹ 5. Joint subluxation

  • Causes of flatfoot in adults

  • â—‹ 1. Posterior tibial tendon dysfunction (PTTD)

  • â—‹ 2. Arthritis: Midfoot, hindfoot, ankle

  • â—‹ 3. Hypermobile flatfoot

  • â—‹ 4. Neuropathic arthropathy

  • â—‹ 5. Fracture malunion

  • â—‹ 6. Inflammatory arthropathy

  • â—‹ 7. Peroneal spastic flatfoot

  • â—‹ 8. Neuromuscular disorder

  • â—‹ 9. Other

  • PTTD etiology

  • PT muscle, tendon anatomy

  • PT function

  • PT muscle activity during gait

  • Factors predisposing to PTTD

  • â—‹ PT gliding resistance

  • PT pathoanatomy

  • Natural history of PTTD

  • PTTD evaluation: symptoms, signs

  • Investigative studies

  • Gait analysis in PTTD patients

  • Simulated walking: Normal, PTTD [4]

  • PTTD treatment

  • PTTD treatment results

  • Failures, complications

Conclusion

  • Current recommendations
