SUMMARY: The anatomy of the psoas minor muscle in human beings has frequently been correlated with ethnic and racial characteristics. The present study had the aim of investigating the anatomy of the psoas minor, by observing its occurrence, distal insertion points, relationship with the psoas major muscle and the relationship between its tendon and muscle portions. Twenty-two human fetuses were used (eleven of each gender), fixed in 10% formol solution that had been perfused through the umbilical artery. The psoas minor muscle was found in eight male fetuses: seven bilaterally and one unilaterally, in the right hemicorpus. Five female fetuses presented the psoas minor muscle: three bilaterally and two unilaterally, one in the right and one in the left hemicorpus. The muscle was independent, inconstant, with unilateral or bilateral presence, with distal insertions at different anatomical points, and its tendon portion was always longer than the belly of the muscle.

There has been very little published literature regarding iliopsoas injuries and there is no information regarding the ultrasound evaluation of abnormal iliopsoas muscles. This manuscript is intended to describe the ultrasound findings in 73 canine agility athletes who had physical examination findings consistent with iliopsoas discomfort. The population was chosen given the high incidence of these animals for the development of iliopsoas injury; likely due to repetitive stress. Methods: Medical records of 73 agility performance canines that underwent musculoskeletal ultrasound evaluation of bilateral iliopsoas muscle groups were retrospectively reviewed. Data included signalment, previous radiographic findings, and ultrasound findings. A 3-tier grading scheme for acute strains was used while the practitioner also evaluated for evidence of chronic injury and bursitis. -
Iliopsoas Pathology, Diagnosis, and Treatment
Iliopsoas Pathology, Diagnosis, and Treatment Christian N. Anderson, MD KEYWORDS Iliopsoas Psoas Coxa saltans interna Snapping hip Iliopsoas bursitis Iliopsoas tendinitis Iliopsoas impingement KEY POINTS The iliopsoas musculotendinous unit is a powerful hip flexor used for normal lower extrem- ity function, but disorders of the iliopsoas can be a significant source of groin pain in the athletic population. Arthroscopic release of the iliopsoas tendon and treatment of coexisting intra-articular ab- normality is effective for patients with painful iliopsoas snapping or impingement that is refractory to conservative treatment. Tendon release has been described at 3 locations: in the central compartment, the periph- eral compartment, and at the lesser trochanter, with similar outcomes observed between the techniques. Releasing the tendon lengthens the musculotendinous unit, resulting in transient hip flexor weakness that typically resolves by 3 to 6 months postoperatively. INTRODUCTION The iliopsoas musculotendinous unit is a powerful hip flexor that is important for normal hip strength and function. Even so, pathologic conditions of the iliopsoas have been implicated as a significant source of anterior hip pain. Iliopsoas disorders have been shown to be the primary cause of chronic groin pain in 12% to 36% of ath- letes and are observed in 25% to 30% of athletes presenting with an acute groin injury.1–4 Described pathologic conditions include iliopsoas bursitis, tendonitis, impingement, and snapping. Acute trauma may result in injury to the musculotendi- nous unit or avulsion fracture of the lesser trochanter. Developing an understanding of the anatomy and function of the musculotendinous unit is necessary to accurately determine the diagnosis and formulate an appropriate treatment strategy for disorders of the iliopsoas. -

Ioannou1 1Vascular Surgery Unit, Department of Thoracic, Cardiac and Vascular Surgery 2Anesthesiology Department, University Hospital of Heraklion, University of Crete Medical School, Heraklion, Greece Abstract: Prosthetic graft infection is a serious complication after reconstructive vascular surgery and the most common anatomic location of this condition is the groin. Traditionally, removal of the prosthesis to eradicate the infectious source and sub- sequent extra-anatomic vascular reconstruction to preserve distal perfusion is considered the safest treatment option. Tunneling of the new graft through uninfected tissues is technically challenging and can usually be performed through three different routes, namely the ilio-psoas muscular lacuna, the obturator foramen and the wing of the iliac bone. We report a single center five-year experience using these techniques emphasizing on technical remarks.

Abstract Injury to the nerves of the lumbar plexus can result in significant disability. Therefore, the clinician should be knowledgeable of both the normal and variant anatomy of these branches. We report what we believe to be the first description of the accessory obturator nerve providing a branch to the psoas major muscle. Such a variant innervation to the psoas major muscle should be kept in mind by those who examine patients or operate near the lumbar plexus.
