The aim of this systematic review was to assess the current validity and
reliability of radiological methods used to measure proximal hip geometry in
children with cerebral palsy. METHOD: A search was conducted using relevant
keywords and inclusion/exclusion criteria of the MEDLINE,
CINALH Plus, Embase,
Web of Science, Academic Search Premier, The Cochrane Library, and PsychINFO
databases. RESULTS: The migration percentage using X-rays showed excellent
reliability and concurrent validity with three-dimensional (3D) measurements from
computed tomography (CT) scans. The acetabular index, measured using X-rays had
good reliability but moderate concurrent validity with 3D CT measurements; 3D CT
scan indexes had greater reliability. The measurement of the neck shaft angle
using X-rays showed excellent concurrent validity with measurements from 3D CT
scans and excellent reliability. Regarding femoral anteversion, one study found
an excellent correlation between two-dimensional CT and clinical assessment and
excellent reliability. Two others showed less evidence for the use of CT
ultrasounds. INTERPRETATION: Most of the X-ray-based measurements showed good to
excellent metrological properties. More metrological evidence is needed for the
assessment of femoral anteversion. Magnetic resonance imaging and
ultrasound-based measurements have great potential although very little
metrological evidence is available.
