Description
INTRODUCTION: The extensor digiti minimi (EDM) is commonly presented as a single tendon originating from the muscle belly and attaching to the fifth digit. Variations in the number of EDM tendons have been previously noted, and possess potentially valuable insights for medical education.
OBJECTIVES:
The primary objective of this project was to examine the gross anatomy of the EDM tendon in a group of cadavers (n=11). The secondary objective of this project is to compare the variations discovered in this group of cadavers to other cadaveric variations reported in the literature. The tertiary objective of this project is to compare data from the cadavers and literature review to commonly used dissector guides utilized for medical education.
METHODS: Eleven cadavers were examined at the anatomy lab of PCOM South Georgia for the number of tendons on the extensor digiti minimi muscle on each hand. The genders and unilateral and bilateral tendon variations were reported.
RESULTS: It was found that it was more common to have multiple tendons from the EDM as opposed to a singular tendon. However, after conducting a cursory review of the literature and cadavers, the more common presentation was found to be a bifurcated EDM.
CONCLUSION: Cadaveric analysis and examination of the literature revealed that many variations exist in the EDM, with the two most common variations being a bifurcation and trifurcation of the tendon.
