Summary

Anterior plate supplementation significantly enhances ankle fusion stability. This surgical technique improves fixation rigidity and reduces micromotion, leading to better outcomes for post-traumatic ankle arthritis treatment.

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Area of Science:

  • Orthopedic Surgery
  • Biomechanics
  • Biomaterials

Background:

  • Ankle arthrodesis is crucial for treating post-traumatic ankle arthritis.
  • Achieving rigid fixation of the tibiotalar interface is key to successful ankle fusion.
  • Current three-screw constructs may have limitations in maintaining stability.

Purpose of the Study:

  • To evaluate the biomechanical impact of anterior plate supplementation.
  • To compare a three-screw construct with and without anterior plating.
  • To assess the effect on tibiotalar interface fixation and motion.

Main Methods:

  • Six fresh-frozen cadaver ankles were used.
  • Constructs were tested with three screws alone and with supplementary anterior plating.

  • Biomechanical testing involved plantarflexion/dorsiflexion, inversion/eversion, and rotational loading.

    • Main Results:

    • Anterior plating increased construct stiffness by 3.5x (sagittal), 1.9x (coronal), and 1.4x (torsion).
    • Plate supplementation significantly reduced tibiotalar interface motion across all loading conditions (p = 0.031).
    • Anterior plating demonstrated superior stability compared to screws alone.

    Conclusions:

    • Anterior plate supplementation enhances construct rigidity in ankle arthrodesis.
    • This technique effectively decreases micromotion at the ankle fusion site.
    • Anterior plating offers improved biomechanical support for treating post-traumatic ankle arthritis.
