The diagnosis requires x-rays of the pelvis, with anteriorposterior (AP) and frog-leg lateral views. [11] The appearance of the head of the femur in relation to the shaft likens that of a "melting ice cream cone", visible with Klein's line. The severity of the disease can be measured using the Southwick angle. [citation needed]
The angle is measured on a frog lateral view of the bilateral hips. It is measured by drawing a line perpendicular to a line connecting two points at the posterior and anterior tips of the epiphysis at the physis. A third line is drawn down the axis of femur. The angle between the perpendicular line and the femoral shaft line is the angle.
Above, the linea aspera is prolonged by three ridges. The lateral ridge is very rough, and runs almost vertically upward to the base of the greater trochanter.It is termed the gluteal tuberosity, and gives attachment to part of the gluteus maximus: its upper part is often elongated into a roughened crest, on which a more or less well-marked, rounded tubercle, the third trochanter, is ...
Scaphoid - DP with Ulna deviation, Lateral, Oblique and DP with 30° angulation; Hip joint: AP and Lateral. [15] The Lauenstein projection a form of examination of the hip joint emphasizing the relationship of the femur to the acetabulum. The knee of the affected leg is flexed, and the thigh is drawn up to nearly a right angle.
Typically, radiographs are taken of the hip from the front (AP view), and side (lateral view). Frog leg views are to be avoided, as they may cause severe pain and further displace the fracture. [5] In situations where a hip fracture is suspected but not obvious on x-ray, an MRI is the next test of choice.
The crescent sign may be best seen in an abducted (frog-legged) position. [1] [4] The crescent sign is caused by the necrotic and repair processes that occur during avascular necrosis. [1] [2] Osteosclerosis occurs at a margin where new bone is placed over dead trabeculae. [1]
It arises from the lateral condyle of the tibia; from the upper three-quarters of the anterior surface of the body of the fibula; from the upper part of the interosseous membrane; from the deep surface of the fascia; and from the intermuscular septa between it and the tibialis anterior on the medial, and the peroneal muscles on the lateral side.
The gastrocnemius muscle (plural gastrocnemii) is a superficial two-headed muscle that is in the back part of the lower leg of humans.It is located superficial to the soleus in the posterior (back) compartment of the leg.
