Area of Science:

  • Orthopedics
  • Embryology
  • Radiology

Background:

  • Intercarpal coalitions are congenital anomalies arising from incomplete embryonic development.
  • These conditions are poorly documented in medical literature.
  • They result from incomplete cavitation of carpal precursors between the 4th and 8th weeks of gestation.

Purpose of the Study:

  • To document the prevalence and characteristics of intercarpal coalitions.
  • To report the largest series of intercarpal coalition cases in English-language literature.

Main Methods:

  • Retrospective review of 36 cases of carpal coalition in 24 patients.
  • Analysis of radiographic findings.
  • Review of patient records for symptoms and clinical presentation.

Main Results:

  • Carpal coalition was found to be significantly more prevalent in American Black individuals compared to White individuals.
  • The condition was asymptomatic in all reported patients.
  • Coalitions were incidental findings on radiographs, often taken for trauma evaluation.

Conclusions:

  • Intercarpal coalitions are more common in American Black populations.
  • These congenital wrist anomalies are frequently asymptomatic and discovered incidentally.
  • This study represents the largest documented series of intercarpal coalitions.
