A Pavlik harness is a brace that is often used to treat
developmental dysplasia of the hip (DDH) in babies
younger than 6 months. The harness has fabric straps and fasteners that fit
around a baby's chest, shoulders, and legs. The harness holds the baby's legs
in a spread position, with the hips bent so that the thighs are out to the
sides. This keeps the head of the thighbone (femur) in the correct position in
the hip socket for normal development. The harness also allows the baby to move
the hip joint, which helps the thighbone to deepen the hip socket. See an
illustration of a

The Pavlik harness successfully makes the hip normal about 90% of the
time.1 The harness is usually worn all the time for
the first few weeks of treatment. At first, the child may continue to wear it
most of the time, removing it only for an hour or so each day for bathing and
for the harness to be cleaned. Later, the child may wear the harness only at
night or during naps. If the femoral head stays properly located in the hip
socket and the hip joint is stable, the child is slowly "weaned" from the
harness. The child may need to wear the harness for several months.
Because babies grow rapidly, the straps and fasteners may need to be
adjusted every 1 to 2 weeks. If the harness is improperly positioned, bone or
nerve damage can develop. The straps can irritate the baby's skin.
The harness fails to correct DDH about 10% of the time. In these
cases, the harness is removed if the hips show no improvement after 3 to 4
weeks and other treatment options are explored.1
