Summary
Anatomical variations in the psoas major muscle are rare. This study documents an unusual multiheaded psoas major muscle, highlighting the importance of recognizing such morphological anomalies.
Area of Science:
- Anatomy
- Morphology
Background:
- Anatomical variations are common in human muscles.
- An exceptionally rare multiheaded psoas major muscle with diverse morphology is presented.
Purpose of the Study:
- To document an uncommon anatomical variation of the psoas major muscle.
- To emphasize the clinical significance of morphological variability in anatomical structures.
Main Methods:
- Observation during routine posterior abdominal wall dissection.
- Identification, photography, and measurement of the abnormal muscle.
Main Results:
- A multiheaded psoas major muscle with atypical morphology was identified.
Conclusions:
- Atypical morphology can have significant clinical implications.
- Documenting morphological variability is crucial for clinical practice and anatomical knowledge.
