Psoas minor is long, slender skeletal muscle it lies anterior to psoas major. It is an inconstant muscle. It was absent in 40-70% of subjects. To determine the frequency and morphometry of psoas minor muscle.: 20 cadavers were dissected during routine dissection for undergraduate students at Ayaan institute of medical sciences, Moinabad, Hyderabad and Government medical college, Mahabubnagar. Bilateral variations were observed in one specimen, unilateral variations were observed in two specimens.: Out of forty specimens Psoas minor was present in three specimens. In one specimen bilateral variations observed, other two specimens unilateral. If it is present, clinical importance to radiologists, surgeons and physiotherapists as it can mimic certain abdominal emergencies.

“…The iliopsoas muscle consists of the psoas major and iliac muscles [49], while the psoas minor muscle is separate from the latter two muscles [24]. The psoas major exists in all individuals [17,34,43,50,54], and is the largest muscle in the cross section of the lower back [44].…”

Purpose The purpose of this study has yielded basic data for use in medical practice by evaluating the relationships between the psoas major, quadratus lumborum, and surrounding vertebrae, and determining landmarks for use during compartmental block surgery of the psoas major and quadratus lumborum. Methods Radiographic data analyses and cadaver psoas major dissections were performed for anatomical observations and relationship comparisons with the quadratus lumborum and vertebrae. Radiological measurement data for the psoas major were obtained, yielding 106 sets of data. Results The length of the psoas major measured from the spinous process of the third lumbar vertebra was significantly larger in males (60.5 ± 8.2 mm) than in females (48.8 ± 5.7 mm) (p < 0.05). also the length of the right psoas major of the fourth lumbar vertebra was significantly larger in males (73.5 ± 8.6 mm) than in females (60.7 ± 7.8 mm) (p < 0.05). The length of the quadratus lumborum of the third lumbar vertebra measured from the spinous process of the third lumbar vertebra was significantly larger in males (89.2 ± 8.1 mm) than in female (74.2 ± 7.7 mm) (p < 0.05). also the length of the quadratus lumborum of the fourth lumbar vertebra measured from the spinous process of the fourth lumbar vertebra was significantly larger in males (103.6 ± 10.6 mm) than in females (91.2 ± 9.9 mm) (p < 0.05). The lengths of the psoas major and quadratus lumborum of the third and fourth lumbar vertebrae decreased with age. Conclusion The accumulating research data of clinical studies of the psoas major, quadratus lumborum, and lumbar approaches will help clinicians to choose the most appropriate methods for treatment and rehabilitation.

“…The psoas muscle group in the posterior abdominal wall primarily comprises three muscles: psoas major (PM), psoas minor (PMi), and psoas tertius. Even though the psoas muscle group occupies the posterior abdominal wall, it belongs to the anterior muscles of pelvic girdle and among them, the psoas major is the most obligate, present in almost all people, while the rest are inconsistent or atrophied and occur occasionally [15,16]. The psoas group muscles, primarily responsible for hip flexion and lateral lumbar spine flexion [3], differ significantly in morphology, origin, and insertion.…”
