Distal swelling of the posterior interosseous nerve, often called Acrel's ganglion, lacks literature. Histological analysis revealed no inflammation or neuronal cells, suggesting "ganglion" is an inappropriate term for these nerve enlargements.

Area of Science:

  • Anatomy
  • Histology
  • Peripheral Nerve Research

Background:

  • Limited existing literature on distal posterior interosseous nerve swelling (Acrel's ganglion).
  • Need for histological and anatomical clarification of these nerve enlargements.

Purpose of the Study:

  • To investigate the histological and anatomical characteristics of distal posterior interosseous nerve swellings.
  • To determine the appropriate terminology for these nerve structures.

Main Methods:

  • Dissection of ten adult cadavers (20 sides).
  • Histological examination of the posterior interosseous nerve swellings.

Main Results:

  • No inflammatory response observed in the peripheral nerve structures.

Related Experiment Videos

  • Absence of neuronal cell bodies within the swellings.
  • Histologically normal peripheral nerve structures identified.

    • Conclusions:

    • The term "ganglia" is inappropriate for distal posterior interosseous nerve enlargements.
    • Etiology of these swellings remains unclear.
    • Further research is needed to understand the nature of these nerve enlargements.
