Summary

Minor displacements of the second tarsometatarsal joint significantly reduce articular contact area, especially with dorsolateral movement. Males consistently show greater contact area than females, even with slight joint instability.

Area of Science:

  • Orthopedics and Biomechanics
  • Foot and Ankle Surgery

Background:

  • The second tarsometatarsal joint is crucial for foot stability.
  • Understanding articular contact area changes is vital for diagnosing injuries.

Purpose of the Study:

  • To analyze the impact of simulated displacements on the articular contact area of the second tarsometatarsal joint.
  • To compare contact area reductions between sexes and displacement types.

Main Methods:

  • Computer-assisted analysis of articular surface contact area.
  • Simulated displacements (dorsal, lateral, dorsolateral) of the second metatarsal.
  • Comparison of contact area in male and female models.

Main Results:

  • Articular contact area decreased proportionally with displacement in both sexes.

Related Experiment Videos

  • Males consistently exhibited greater contact area than females across all simulated displacements.
  • Dorsolateral displacement caused the most significant reduction (38.6% at 3 mm).

    • Conclusions:

    • Even subtle, radiographically undetectable displacements significantly decrease second tarsometatarsal joint contact area.
    • Computed tomography is recommended for evaluating subtle second tarsometatarsal injuries to detect minor displacements.
