The iliopsoas of the rat is composed of two muscles - the psoas major muscle and the iliacus muscle. The psoas major muscle arises from all the lumbar vertebrae and the iliacus muscle from the fifth and sixth lumbar vertebrae and ilium. Their common insertion point is the lesser trochanter of the femur, and their common action is the lateral rotation of the femur and flexion of the hip joint. Unlike humans, the rat is a quadruped and only occasionally rises up on its hind legs. Therefore, it is expected that the fibre type composition of the rat iliopsoas muscle will be different than that of humans...

BACKGROUND: Traumatic iliacus muscle injury is rare; it is usually caused by trauma or intense exercise involving the pelvic girdle; it can produce a hematoma with femoral nerve neuropathy. Spontaneous muscle hematomas occur in patients with coagulation disorders. CLINICAL CASE: A 45-year-old male with 18 days of evolution, with an intense pain in the right buttock, groin and iliac fossa, with an inability for hip flexion and ambulation caused by inadequate exercise (supine double leg lifts)...

BACKGROUND: Pyomyositis is a rare bacterial infection of striated muscle, usually caused by Staphylococcus aureus. CASE DESCRIPTION: A healthy 9-year-old boy was referred to us because of pain in the hip and fever. We noticed he could point to the pain with one finger; this is referred to as 'pinpoint pain'. An MRI indicated a diagnosis of pyomyositis of the iliacus muscle and piriformis. The infection was caused by S. aureus. The boy recovered completely and swiftly with antibiotic therapy...

Quadratus lumborum block has recently been described as an effective and long-lasting analgesic strategy for various abdominal operations, including gynaecological laparoscopy. Despite evidence that the analgesic effect is mediated by indirect paravertebral block and that local anaesthetic spreads to the lumbar paravertebral space, there have been no reports to date of lower limb motor weakness. We present a patient with unilateral hip flexion and knee extension weakness leading to unplanned overnight admission following lateral quadratus lumborum block with 20 ml levobupivacaine 0...

Age-related increased hip extensor recruitment during gait is a proposed compensation strategy for reduced ankle power generation and may indicate a distal-to-proximal shift in muscle function with age. Extending beyond joint level analyses, identifying age-related changes at the muscle level could capture more closely the underlying mechanisms responsible for movement. The purpose of this study was to characterize and compare muscle forces and induced accelerations during gait in healthy older adults with those of young adults...

Staphylococcus Aureus is a Gram-positive cocci bacteria which had been found to be the causative organism in over 88% of patients with primary iliopsoas abscess. We report the case of a 53-year-old diabetic woman with end-stage renal failure diagnosed with left iliopsoas abscess with a catheter-related infection. Computed tomogram (CT) of abdomen and pelvis revealed hypodense lesions of left psoas, iliacus and quadratus lumborum suggestive of psoas abscesses. In addition, osteomyelitis changes at left sacroiliac and hip joint were seen...

Iliacus compartment syndrome is a rare retroperitoneal compartment neuropathy caused by bleeding within the iliacus muscle leading to hematoma formation and compression upon the femoral nerve, causing both sensory and motor deficits. A 75-year-old Caucasian man presented with severe right hip pain associated with motor and sensory deficit in the right lower extremity, 2 weeks post elective balloon aortic valvuloplasty for critical aortic stenosis. A non-contrast computed tomography scan revealed low-attenuation areas in keeping with an iliacus hematoma...

Meralgia paresthetica refers to the entrapment of the lateral femoral cutaneous nerve at the level of the inguinal ligament. The lateral femoral cutaneous nerve - a purely sensory nerve - arises from the L2 and L3 spinal nerve roots, travels downward lateral to the psoas muscle, and then crosses the iliacus muscle. Close to the anterior superior iliac spine, the nerve courses in contact with the lateral aspect of the inguinal ligament and eventually innervates the lateral thigh. The entrapment syndrome is usually idiopathic but can also ensue due to trauma/overuse, pelvic and retroperitoneal tumors, stretching of the nerve due to prolonged leg/trunk hyperextension, leg length discrepancies, prolonged standing, external compression by belts, weight gain, and tight clothing...

Psoas abscesses could originate from an adjacent source of infection in the abdominopelvic cavity known as a secondary complication of acute appendicitis. However, it is considered as a very rare event when occurring late after the presentation of appendicitis. Whether it is the source or complication of acute appendicitis following appendectomy remains unclear. A 25-year-old man was admitted to our center with fever and abdominal pain. His past medical history was unremarkable except for having an acute appendicitis and complicated appendectomy 4 years before presenting illness...

Recumbent bicycles (RB) are high performance, human-powered vehicles. In comparison to normal/upright bicycles (NB) the RB may allow individuals to reach higher speeds due to aerodynamic advantages. The purpose of this investigation was to compare the non-aerodynamic factors that may potentially influence the performance of the two bicycles. 3D body centre of mass (BCoM) trajectory, its symmetries, and the components of the total mechanical work necessary to sustain cycling were assessed through 3D kinematics and computer simulations...

BACKGROUND: Secondary hyperalgesia in individuals with less severe levels of knee osteoarthritis remains unclear. The objective of this study was to measure the pressure pain threshold (PPT) of individuals with mild or moderate knee osteoarthritis (KOA) and compare with no osteoarthritis. METHODS: Ten healthy controls and 30 individuals with mild or moderate KOA divided into two groups (unilateral and bilateral involvement) were included. Dermatomes (L1, L2, L3, L4, L5, S1, and S2), myotomes (vastus medialis, vastus lateralis, rectus femoris, adductor longus, tibialis anterior, peroneus longus, iliacus, quadratus lumborum, and popliteus muscles), and sclerotomes (L1-L2, L2-L3, L3-L4, L4-L5 supraspinous ligaments), over the L5-S1 and S1-S2 sacral areas, pes anserinus bursae, and at the patellar tendon) PPT were assessed and compared between individuals with and without KOA...

OBJECTIVES: Previous research has shown that motor control training improved size and function of trunk muscles in elite football players with and without low back pain (LBP). Imbalances in hip muscles have been found in athletes with LBP and it is not known if motor control training can change these muscles. This study investigated if a motor control intervention program affected hip muscle size in elite football players with and without LBP. DESIGN: Panel-randomised intervention design...

The non-typhoidal bacterium Salmonella enterica subspecies enterica serovar Othmarschen (Salmonella Othmarschen) is a rare human pathogen. Abscess formation due to non-typhoidal Salmonella infections is a very rare complication in this antibiotic era. We report the first case of iliacus abscess after a short period of gastroenteritis which was caused by non-typhoidal Salmonella enterica belonging to group C1, serovar Othmarschen in a patient without any underlying conditions. A young female presented in our hospital complaining of pain in right hip joint area...

Study Design Case report. Objective This report describes the first case of a sacroiliac coalition, its clinical features, the diagnostic difficulties, and the surgical treatment chosen in this case. Methods A 33-year-old man presented to our outpatient clinics complaining of severe left-sided low back pain with an intermitted nondermatomal radiation into the left thigh. The only abnormality on a pelvic radiograph was a coin-size, faint hyperdensity, which was almost overlooked. Subsequent computed tomography (CT) and magnetic resonance imaging (MRI) confirmed two bridging bone spurs on the anterior surface of the left joint with a fibrous interruption at the apex...

STUDY OBJECTIVE: The femoral, lateral femoral cutaneous, and obturator nerves (ONs) can reportedly be blocked using a single-injection deep to the fascia iliaca (FI) at the level of the inguinal ligament. Two commonly used methods (the FI compartment and 3-in-1 blocks) have produced inconsistent results with respect to local anesthetic distribution and effect on the ON. To date, no study of either method has been performed using advanced imaging techniques to document both needle placement and local anesthetic distribution...
