First naviculocuneiform coalitions, often presenting as mild foot pain, can be misdiagnosed. This study identified three morphological patterns, suggesting a developmental progression and highlighting the need for further incidence research.

Area of Science:

  • Orthopedics
  • Podiatry
  • Radiology

Background:

  • Isolated first naviculocuneiform coalitions are rare foot conditions.
  • Symptoms can be subtle, leading to misdiagnosis as osteoarthritis or bone cysts.
  • Computed tomography (CT) is crucial for accurate diagnosis.

Purpose of the Study:

  • To analyze the clinical presentation and morphological patterns of first naviculocuneiform coalitions.
  • To hypothesize a developmental progression of coalition patterns.
  • To emphasize the potential for underdiagnosis and suggest further incidence studies.

Main Methods:

  • Clinical analysis of 60 feet in 40 patients with first naviculocuneiform coalitions.
  • Morphological classification into irregular, cystic, and combined patterns using CT scans.

  • Correlation of patterns with patient age.

    • Main Results:

    • Mild medioplantar pain at the first naviculocuneiform joint was the most common symptom.
    • 25% of analyzed feet were asymptomatic.
    • Three distinct morphological patterns (irregular, cystic, combined) were identified via CT.

    Conclusions:

    • A hypothesized developmental sequence from irregular to cystic to combined coalition patterns exists.
    • First naviculocuneiform coalitions may be underdiagnosed due to subtle symptoms or ethnic factors.
    • Re-evaluation of the actual incidence of this condition is recommended.
