ISOLATED RIGHT PSOAS MINOR MUSCLE: A CASE STUDY AND LITERATURE REVIEW.

This case report describes a unilateral right psoas minor muscle found during dissection. The muscle was absent on the left side. This nding adds to our understanding of the psoas minor's variable presence. The psoas minor is a vestigial muscle with potential clinical signicance. Its anatomical variations can be misinterpreted as pathology and may be relevant during surgery in the retroperitoneal space. The function of the psoas minor is unclear, but it may assist the psoas major in exion, stability, and tensioning fascia. The presence of a unilateral psoas minor raises questions about its functional signicance. This report and literature review highlights the importance of understanding psoas minor variations.
