Axial T1-weighted (left) and fat-suppressed T2-weighted (right) images show crowding of fibers and edema in fibers (arrows) of quadratus femoris muscle. [1] The muscle consists of a lateral and medial head, coming together to form the bulk of this muscle. 22, No. 6, American Journal of Roentgenology, Vol. 7 13-year-old girl with left hip pain and normal hip arthrogram and normal anatomy of quadratus femoris muscle. 1, European Journal of Radiology, Vol. This finding is most commonly seen along the distal myotendinous junction along the posteromedial aspect of the proximal femur. $"` K b*`AD2v FF%0-y@B}#cF > Imaging Key Wrist Ligaments: What the Surgeon Needs the Radiologist to Know, Review. The quadratus femoris muscle is situated along the posterior aspect of the hip joint and, as the name suggests, has a quadrangular, somewhat rectangular, appearance. This branch comes off of the lateral plantar nerve near its origin and travels to supply the rest of the superficial layer muscle of the foot and the QP muscle. Quadratus plantae: Originates from the plantar surface of the calcaneus. ISBN:0702051314. 4.

CONCLUSION. I'll provide an overview of the imaging sequences used to assess pathologies of the midfoot and we will review the MRI evaluation of the midfoot anatomy using a checklist approach in the coronal, sagittal and axial imaging planes. Although at first glance it may be difficult to differentiate strain and impingement, careful analysis of the location of edema and the configuration of the muscle fibers and surrounding structures can aid in differentiating the two entities. 48, No. Single arrow indicates origin of quadratus femoris; arrowhead, insertion; asterisk, obturator externus muscle; oval, sciatic nerve; double arrow, hamstring origin. Concise, to-the-point text covers MRI for the entire musculoskeletal system, presented in a highly templated format. endstream endobj 504 0 obj <> endobj 505 0 obj <. These disorders are classified on the basis of anatomic origin and predominant location of heel pain to foster a better understanding of this complaint. 0 Unable to process the form. The quadratus plantae ( flexor accessorius) is separated from the muscles of the first layer by the lateral plantar vessels and nerve. The majority of patients with heel pain can be successfully treated conservatively, but in cases requiring surgery (eg, plantar fascia rupture in competitive athletes, deeply infiltrating plantar fibromatosis, masses causing tarsal tunnel syndrome), MR imaging is especially useful in planning surgical treatment by showing the exact location and extent of the lesion. The quadratus plantae is a muscle in the foot that extends from the anterior (front) of the calcaneus (heel bone) to the tendons of the digitorum longus muscle in the leg. Quadratus plantae injuries are indicated by sharp pain or sensation of numbness in the heel. 6, The Journal of Foot and Ankle Surgery, Vol. 66, No. 3, Medical Clinics of North America, Vol. 67, No. Address correspondence to A. Kassarjian ([emailprotected]com). 12, 1 November 2008 | RadioGraphics, Vol. Heel pain is a common and frequently disabling clinical complaint that may be caused by a broad spectrum of osseous or soft-tissue disorders. Plantar fasciitis and calcaneal spur formation are associated with abductor digiti minimi atrophy on MRI of the foot. dakota leeds. The muscle is often best evaluated on axial images, on which the origin, insertion, and anterior and posterior relations can be evaluated (Figs. 1, 2, 3). 10, Journal of the American Academy of Orthopaedic Surgeons, Vol. ANAT SCI INT. The treatment is generally via a non-surgical approach (e.g. The quadratus femoris muscle is easily identified on axial, sagittal, and, depending on slice thickness, coronal images of the hip. Arrow indicates inferior gemellus muscle; arrowheads, sciatic nerve. 4, 5, 6, 7). 2, Journal of Pathology and Translational Medicine, Vol. Because of the ever-increasing use of MRI, with or without MR arthrography, in the evaluation of hip pain, radiologists must be aware of subtle and less common abnormalities that mimic both intraarticular and extraarticular hip disease. . High-Resolution 3-T MRI of the Fingers: Review of Anatomy and Common Tendon and Ligament Injuries, Review. 8 13-year-old girl with right hip pain.

Baxter neuropathy is a nerve entrapment syndrome resulting from the compression of the inferior calcaneal nerve (Baxter nerve). 3. 8). 2. Quadratus lumborum pain involves discomfort in the muscle that is located deep in the lower back on both sides of the spine. 3, Reumatologa Clnica (English Edition), Vol. In addition, axial images facilitate assessment of the relation between the muscle belly and the surrounding structures. 12 25-year-old woman with exercise-induced edema of quadratus femoris muscle. With its superior soft-tissue contrast resolution and multiplanar capability, magnetic resonance (MR) imaging can help determine the cause of heel pain and help assess the extent and severity of the disease in ambiguous or clinically equivocal cases. Check for errors and try again. (e-mail. The quadratus femoris muscle acts as an adductor and external rotator of the hip. If substantial edema or fluid is present in the region, the findings can mimic those of other entities. It is part of the group of muscles known as the lateral, or external, rotators of the thigh. 1. 1, Clinics in Podiatric Medicine and Surgery, Vol. If a substantial amount of fluid is found (rare in our experience), the findings can theoretically mimic iliopsoas bursitis if the fluid is near the lesser trochanter and mimic ischial bursitis if the fluid is near the ischial tuberosity. Chundru U, Liebeskind A, Seidelmann F et-al. MRI of the Quadratus Femoris Muscle: Anatomic Considerations and Pathologic Lesions, Original Research. Sickle hemoglobin is a mutant hemoglobin in which valine has been substituted for the glutamic acid normally at the sixth amino acid of the b-globin chain. Last's Anatomy. Asterisk indicates obturator externus muscle; oval, sciatic nerve; arrowhead, intact quadratus femoris tendon insertion; double arrow, hamstring origin. 10, No. There are three sites of possible entrapment: The affected region shows decreased signal intensity on T1 and increased signal intensity on T2 with fat-saturation due to increased extracellular water content and decreased muscle fiber volumes of the involved muscles innervated by the inferior calcaneal nerve. Torriani et al. Lesions of the quadratus femoris have been implicated as a cause of hip pain. Accessory muscles are isointense to skeletal muscle on all pulse sequences, and can insert by fleshy muscular or tendinous insertions. 1 If left untreated, it may cause severe and debilitating discomfort that can ultimately lead to dysfunction.
