Ankle Joint

2.0K
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...

Summary

Resecting up to 30% of the medial talar facet and adjacent posterior facet does not cause subtalar joint instability in biomechanical tests. This finding is crucial for surgical planning involving pathologies of the medial talus.

Area of Science:

  • Orthopedic surgery
  • Biomechanics
  • Anatomy

Background:

  • Pathologies of the medial talus, including fractures and tarsal coalitions, can cause pain and nonunion.
  • Bony resection is a potential treatment, but the threshold for subtalar joint instability after medial talar resection is unknown.

Purpose of the Study:

  • To evaluate the impact of limited resection of the medial talar facet and anteromedial posterior talar facet on subtalar joint stability.

Main Methods:

  • Human cadaveric lower limbs underwent simulated weight-bearing with CT scans.
  • Sequential resection of 10%, 20%, and 30% of the medial and anteromedial posterior talar facets was performed.
  • Subtalar joint stability was assessed through measurements of vertical angulation, talar subluxation, and various angular parameters.

Main Results:

  • No gross clinical instability was observed in any specimen.
  • No significant differences in measured parameters were found between intact and resected states, or among different resection percentages (P ≥ 0.10).

Conclusions:

  • Resection of up to 30% of the medial talar facet and anteromedial posterior facet does not induce measurable subtalar joint instability in a biomechanical model with intact ligaments.
  • These findings suggest a potential safety margin for surgical debridement in the medial talus.
