A

performed in infants less than 3 months old

  • 1st perform the Barlow sign where the legs are bent to 90 degrees and brought to the midline then pushed posteriorly (dislocation of the femoral head from the acetabulum can be palpated if Barlow sign is positive)
  • 2nd perform the Ortolani sign where the legs are abducted and thighs pushed anteriorly, if a click is heard the Ortalani sign is positive and the femoral head has clicked back into the socket
  • > nonspecific findings
  • > each hip done one at a time
77
Q
