Description[edit | edit source]
-Psoas Minor is a long slender muscle, placed in front of the Psoas major.[1]
-The psoas minor is a thin, paired muscle of the posterior abdominopelvic region. It is located on the anterior aspect of the psoas major muscle, but does not extend with it beyond the inguinal ligament. Despite its close relation to the psoas major muscle, the psoas minor is not considered part of the iliopsoas muscle complex.
Origin[edit | edit source]
-Lateral aspect of vertebral body of 12th thoracic and 1st lumbar vertebrae [2]
Insertion[edit | edit source]
-Pectineal line of pubis [2]
Nerve Supply[edit | edit source]
-Small branch from the initial part of the lumbar ventral ramus(L1) [2]
Blood Supply[edit | edit source]
-Lumbar arteries, lumbar branch of the iliolumbar artery. [2]
Action[edit | edit source]
-Assists with flexion of the lumbar vertebral column [2]
Clinical relevance[edit | edit source]
iliopsoas tendinitis[edit | edit source]
- a rare cause of pain in the groin that has been associated with inflammatory arthritis, acute trauma, and overuse syndromes
- commonly seen in athletes, often runners, dancers, and high jumpers
- usually results from overuse or trauma. It is frequently known as jumpers hip or dancers hip
- iliopsoas tendonitis following total arthroscopic hip replacement iliopsoas syndrome can be reasonably commonplace
- psoas syndrome is usually a term used interchangeably with iliopsoas tendinitis, internal snapping hip, or iliopsoas impingement
Treatment[edit | edit source]
-nonoperative treatment;
- including rest,
- nonsteroidal anti-inflammatory medications,
- and a stretching program, has been recommended for the treatment of this condition - exercise programs that the patient can do at home with a focus on hip rotation have demonstrated effectiveness in the reduction of pain and improvement of activity for patients in pain
-surgical interventon
- for refractory cases requiring surgery, arthroscopic lengthening of the tendon can be completed for relief, and correcting intra-articular pathology can be done
- release of the psoas tendon from the insertion is also a possible surgical option
