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.
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. This is also called the frog-leg position.
The Sims' position is a variation of the left lateral position. The patient is usually awake and helps with the positioning. The patient will roll to his or her left side. Keeping the left leg straight, the patient will slide the left hip back and bend the right leg. This position allows access to the anus.
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.
Loss of this concavity or bone bulging may lead to cam type impingement. The degree of this deformity can be measured by the alpha angle. Although it can be measured in the cross-lateral view, the 45° Dunn view is considered more sensitive and the frog leg view more specific in determining pathologic values. Normal: ≤68° in men, ≤50° in ...
Human positions refer to the different physical configurations that the human body can take. There are several synonyms that refer to human positioning, often used interchangeably, but having specific nuances of meaning. [1] Position is a general term for a configuration of the human body. Posture means an intentionally or habitually assumed ...
Klein's line or the line of Klein is a virtual line that can be drawn on an X-ray of an adolescent's hip parallel to the anatomically upper edge of the femoral neck.It was the first tool to aid in the early diagnosis of a slipped capital femoral epiphysis (SCFE), which if treated late or left untreated leads to crippling arthritis, leg length discrepancy and lost range of motion.
