Summary

Posterior calcaneal osteotomy corrects foot deformities by realigning the heel bone. This procedure enhances subtalar joint stability and can dynamically correct Achilles tendon alignment for improved foot function.

Area of Science:

  • Orthopedic Surgery
  • Podiatric Medicine
  • Biomechanics

Background:

  • Flatfoot deformity involves complex multiplanar displacement of the calcaneus.
  • Subtalar joint instability and forefoot supinatus are common findings.
  • Posterior calcaneal osteotomy is a surgical option for addressing these issues.

Purpose of the Study:

  • To describe the biomechanical effects and clinical applications of posterior calcaneal osteotomy.
  • To evaluate its role in correcting calcaneal displacement and associated deformities.
  • To assess its impact on subtalar joint stability and Achilles tendon mechanics.

Main Methods:

  • Posterior calcaneal osteotomy involves surgical cutting and repositioning of the calcaneus.
  • Correction addresses frontal, transverse, and sagittal plane displacements.

  • Assessment includes evaluation of midtarsal joint and Achilles tendon dynamics.

    • Main Results:

    • The procedure effectively corrects calcaneal displacement in multiple planes.
    • It enhances rotational stability of the subtalar joint in a supinatory direction.
    • Displacement of the calcaneal fragment dynamically influences Achilles tendon alignment.

    Conclusions:

    • Posterior calcaneal osteotomy is a versatile procedure for flatfoot deformity.
    • It offers biomechanical advantages by stabilizing the subtalar joint and altering tendon forces.
    • Consideration of adaptive changes is necessary for optimal outcomes.
