Summary

Transitional vertebrae in males can alter lumbosacral dermatome positions. This study found that vertebral transitions significantly shift the dermatome gap ventrally compared to normal spinal configurations.

Area of Science:

  • Anatomy
  • Radiology
  • Neurology

Background:

  • The lumbosacral dermatome map is crucial for neurological assessments.
  • Transitional vertebrae are anatomical variations that may influence neuro-anatomical structures.

Purpose of the Study:

  • To investigate if the location of lumbosacral dermatomes differs in individuals with transitional vertebrae.
  • To determine the relationship between vertebral anomalies and dermatome positioning.

Main Methods:

  • Radiographic assessment of thoracolumbar and lumbosacral transitional vertebrae in 50 male patients.
  • Delineation of the dermatome gap using the cremasteric reflex, which sharply demarcates at the gap.

Main Results:

  • Thirty-two patients had normal spinal configurations; 10 had transitional vertebrae.
  • Patients with cranial displacement of transitional vertebrae exhibited a significantly more ventral dermatome gap compared to those with normal configurations.

Conclusions:

  • The study supports the hypothesis that lumbosacral dermatomes can have a variant position in males with transitional vertebrae.
  • This finding has implications for understanding anatomical variations in the lumbosacral region.
