|
abduction
|
to move away from the body
|
|
|
adduction
|
to move toward the body
|
|
|
Barlow maneuver
|
the pt lies in the supine position with the hip flexed 90 degrees and adducted/ downward and outward pressure is applied/ if the hip is dislocated, the examiner will feel the femoral head move out of the acetabulum
|
|
|
acetabulum
|
the acetabulum is the concave articular surface of the pelvis, formed by the parts of three bones, the ilium, ischium, and pubis/ the head of the femur articulates with the pelvis at the acetabulum, forming the hip joint
|
|
|
ilium, ischium, and pubis
|
What three bones form the acetabulum?
|
|
|
Development Displacement of the Hip (DDH)
|
abnormal condition of the hip that results in congenital hip dysplasia/ includes dysplastic, subluxated, dislocatable, and dislocated hips
|
|
|
fascia lata
|
deep fascia of the thigh
|
|
|
femoral triangle
|
description of a region at the fron tof the upper thigh, just below the inguinal ligament
|
|
|
frank dislocation
|
the hip is laterally and posteriorly displaced to the extent that the femoral head has no contact with the acetabulum and the normal U configuration cannot be obtained on ultrasound
|
|
|
Galeazzi sign
|
the knee is lower in position on the affected side when the pt is supine and the knee are flexed/ on physical exam, the knee is lower in position on the affected side of the neonate with DDH when the pt is supine and the knees are flexed
|
|
|
hip joint
|
formed by the articulation of the head of the femur with the acetabulum of the hip bone
|
|
|
Ortolani maneuver
|
pt lies in the supine position/ the examiner's hand is placed around the hip to be examined with the fingers over the femoral head/ the hip is flexed 90 degrees and the thigh is abducted
|
|
|
