Area of Science:

  • Orthopedic Surgery
  • Radiology
  • Anatomy

Background:

  • Second metatarsophalangeal joint arthrography is vital for assessing plantar plate integrity.
  • Interpreting arthrographic filling patterns requires further understanding of their relation to soft-tissue pathology.

Purpose of the Study:

  • To evaluate dye patterns in second metatarsophalangeal joint arthrograms.
  • To correlate arthrographic findings with anatomical lesions or variants in cadaveric specimens.

Main Methods:

  • Thirty-nine cadaveric specimens underwent second metatarsophalangeal joint arthrography using radiopaque dye.
  • Arthrographic findings were recorded, and specimens with dye extravasation were dissected to identify soft-tissue abnormalities.

Main Results:

Related Experiment Videos

  • Abnormal dye extravasation outside the joint capsule was observed in 21% of specimens.
  • Plantar plate tears were identified in 2 specimens with extravasation.
  • Filling of the first intermetatarsophalangeal bursa occurred in 6 specimens, suggesting an anatomical variance.

Conclusions:

  • Anatomical variations of the second metatarsophalangeal joint capsule exist.
  • Arthrographic findings must be interpreted in conjunction with the clinical presentation to accurately diagnose pathology.
