Heel pain--operative results. Concise, to-the-point text covers MRI for the entire musculoskeletal system, presented in a highly templated format. The entity of impingement of the quadratus femoris muscle, first described by Kassarjian [4] in three patients, is visualized as crowding of the fibers of the muscle belly in the space between the ischium or hamstring tendons and the posteromedial femur. Impingement of the quadratus femoris muscle is best assessed on axial images, on which the location of the edema can be accurately localized. Along its anterior aspect, the quadratus femoris is bordered by the obturator externus muscle; along its posterior aspect it is bordered by fat and the sciatic nerve (Fig. Strain and impingement are the two most common primary lesions of this muscle. F = femur, I = ischium. 7. Hip Anatomic Variants That May Mimic Abnormalities at MRI: Labral Variants.

These are typical findings of impingement of quadratus femoris. The quadratus plantae muscle (QP) is also indicated. The first branch of the lateral plantar nerve (Baxter's nerve) is particularly at risk. However, because of small sample size and lack of control for degree of hip rotation at imaging, the validity of such measurements remains unclear.

Photograph shows axial gross anatomic relations. The first branch of the LPN, Baxter's nerve (also known as the inferior calcaneal nerve), originates from the LPN at various levels beneath the deep fascia of the abductor hallucis muscle. (1984) Foot & ankle. 5. Radiology or diagnostic imaging is a medical subspecialty that uses medical imaging equipment, such as X-rays, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound. The disorders include plantar fascial lesions (fasciitis, rupture, fibromatosis, xanthoma), tendinous lesions (tendinitis, tenosynovitis), osseous lesions (fractures, bone bruises, osteomyelitis, tumors), bursal lesions (retrocalcaneal bursitis, retroachilleal bursitis), tarsal tunnel syndrome, and heel plantar fat pad abnormalities. The lateral plantar nerve or the external plantar nerve (latin: nervus plantaris lateralis), it enters the sole of the foot by passing deep to the proximal insertion of the abductor hallucis muscle. Abductor digiti minimi: Originates from the medial and lateral process of the calcaneal tuberosity. Careful analysis of the images and scrutiny of the actual location of fluid and edema and local muscle and tendon anatomy typically aids differentiation of these entities. 9 73-year-old woman with right posterior hip and buttock pain and impingement of quadratus femoris. 7, Surgical and Radiologic Anatomy, Vol. 9, No. Check for errors and try again.

Along with the gluteus medius, gluteus minimus and tensor fasciae latae, it belongs to the gluteal group of the hip muscles . Photograph shows coronal gross anatomy. The fibers are more closely opposed along the femoral end of the muscle, are more loosely arranged, and have more interspersed fat along the ischial aspect. It therefore is important to be familiar with the anatomy of the quadratus muscle and to be able to diagnose the causes of abnormal signal intensity in the quadratus femoris, which include tears and impingement.

MRI demonstrates muscle enlargement and diffuse increased T2 signal which may involve one or more muscles. %%EOF The first is the between the quadratus plantae muscle and the fascia of deep fascia of the abductor hallucis. It continues across the sole anteriorly and laterally, between the digitorum brevis and quadratus plantae muscles innervating both of these muscles. Axial T1-weighted MR image shows complete atrophy of quadratus femoris. Arrow indicates inferior gemellus muscle. Address reprint requests to J.A.N. Subsequent reports described similar cases and confirmed the association between impingement of the quadratus femoris muscle and hip pain. As with most muscle strains in other parts of the body, strain of the quadratus femoris muscle appears as edema centered along the myotendinous junction of the quadratus femoris muscle with or without associated fluid. The quadratus plantae is what provides stability in the foot.

The gluteus maximus is the most superficial gluteal muscle that forms the prominence of the gluteal region. ISBN:0702033944. Although with imaging alone the findings can resemble mild acute (partial) tears, the lack of muscle fiber disruption and the clinical history often can help differentiate acute partial tear from exercise-induced edema, such as delayed-onset muscle soreness.
