Objectives:
Developmental dysplasia
of the hip (DDH) is an important problem. Ultrasonography (US) is a proper
method before 6 months of age. For older children, plain radiographs can be
useful. Six risk factors are emphasized: breech
presentation, female sex, a positive family history, being first-born, left hip
affected, and mode of delivery. In some centers, clinicians prefer to
perform a control US examination or pelvic radiographs after 6 months of age
for the children having a positive family history. We aimed to evaluate the
necessity of control US/direct radiography examinations.
Methods: A total of 205 children with a positive family history for DDH are
included. US examinations are performed according to Graf’s method. We have
evaluated direct radiographs by using Hilgenreiner, Perkin, and Shenton lines,
acetabular angle.
Results: Initial US examinations are performed at a median age
of 8.3 weeks. Seventy-four patients (36%) had a repeat ultrasound scan at a
median age of 7 months; none of them demonstrated abnormal findings. One hundred
and thirty-one patients (63.9%) had control radiographs at a median age of 8.2
months. Shenton line is considered as normal, and the upper femoral epiphysis
is located in inferomedial quadrant according to Hilgenreiner and Perkin lines.
Conclusions: A positive family history for DDH may be a less
important reason for performing control US or radiographic examination.
Patients with a normal screening US result and having risk factors can be
discharged from follow up safely, so that unnecessary examinations and family
anxiety will be reduced.
