Subtalar joint fusion addresses hindfoot malunions and fractures, aiming to restore height and heel alignment. Bone grafting techniques stabilize reorientation for improved gait and function.

Area of Science:

  • Orthopedic Surgery
  • Biomechanics
  • Podiatric Medicine

Context:

  • The subtalar joint, crucial for weight-bearing, is susceptible to post-traumatic malunions and congenital abnormalities.
  • Fractures of the os calcis (heel bone) frequently lead to hindfoot height loss and heel malorientation, impairing gait.
  • Current fusion techniques may necessitate bone grafting to maintain achieved reorientation and prevent height loss.

Purpose:

  • To describe a surgical technique for subtalar joint fusion that addresses height loss and heel malorientation.
  • To highlight the use of autologous tricortical bone blocks for stabilizing complex hindfoot reconstructions.
  • To emphasize the importance of preserving hindfoot height during surgical correction.

Summary:

  • Subtalar joint fusion is indicated for articular problems causing malunions or abnormalities.

Related Experiment Videos

  • Techniques involve liberating the calcaneus for reorientation, often creating an empty space requiring stabilization.
  • Autologous tricortical bone grafts from the posterior iliac crest are used to stabilize the corrected alignment.
  • A posterolateral surgical approach is optimal for these procedures.

    • Impact:

    • Restores hindfoot height and heel alignment, crucial for functional and stable gait.
    • Provides a stable fusion in cases of complex fractures and malunions.
    • Improves patient outcomes by addressing structural deformities of the lower ankle joint.
