The Pavlik harness: week by week, and what to expect
Written by Dr. Mutasem Aldhoon, pediatric orthopedic consultant · Medically reviewed by the Baby Hip Center pediatric orthopedic team · Last reviewed September 1, 2026
The Pavlik harness holds your baby's hips bent and gently spread so the ball sits deep in the socket while the socket grows around it. It is usually worn full time for six to twelve weeks, starting before six months of age, and it corrects the great majority of dysplastic and dislocated hips without surgery.
What the harness does
The harness is a set of soft straps: a chest band, two shoulder straps, and a stirrup on each leg. The front straps hold the hips bent to roughly 90-100°, and the back straps stop the legs from coming together. In that position the femoral head presses into the deepest part of the socket, and the socket responds by deepening around it. Your baby still kicks freely — the harness restricts the leg coming inwards, not movement in general.
A typical timeline
| When | What usually happens |
|---|---|
| Fitting day | Straps adjusted and marked; you are shown how to change a nappy and dress your baby |
| 1-2 weeks | First check, often with an ultrasound to confirm the hip is seated |
| 2-6 weeks | Full-time wear; straps let out as your baby grows |
| 6-12 weeks | If the scans show a maturing socket, some teams begin weaning to nights only |
| After weaning | Ultrasound or X-ray follow-up, sometimes continuing to walking age |
Do not adjust or remove it yourself
The straps are set at a precise position. Too much spread risks the blood supply to the femoral head, too little and the hip does not stay seated. Unless your team has specifically taught you a removal routine, the harness stays on for bathing, sleeping and feeding.
Practical day-to-day care
- Nappies go under the straps, not over them. Use a smaller size than usual so it does not bulk out the hips.
- Dress with a thin cotton vest under the chest band to protect the skin, and put clothes on over the harness.
- Wash your baby in sections with a cloth rather than immersing, unless you have been shown a safe removal routine.
- Check the skin behind the knees, in the groin, at the shoulders and under the chest band once a day.
- Massage the skin gently in the creases; report any redness that does not fade, or any broken skin.
- Car seats and prams are usually fine — your baby's legs simply sit wider apart than normal.
Skin problems and pressure areas
Mild redness where a strap crosses the skin is common in the first days as the fit settles. Persistent redness, moisture and broken skin are not — they usually mean the strap has slipped or the nappy is sitting on top of it. This is worth a phone call rather than a wait-and-see.
Sleep and comfort
Most babies settle within a few days. Babies fitted in the first weeks of life often barely notice; older babies who have learned to straighten and stretch their legs may protest for longer. Persistent inconsolable crying, refusal to move a leg at all, or new stiffness should be reported — occasionally a hip has slipped or a nerve is being pressed.
How well does it work?
Results are best in the youngest babies with the mildest instability, and less good with a fully dislocated hip, a Graf type IV hip, or a baby who has already passed six months. When the harness does not achieve a stable, seated hip after a few weeks, continuing is not harmless — persistent pressure on an unseated hip can damage the socket rim. That is why the early ultrasound checks exist, and why teams change plan rather than persevere.
If the harness does not work
- A rigid abduction brace or a different orthosis may be tried, which holds position more firmly than straps.
- Closed reduction under anaesthetic, with the hip then held in a spica cast, is the usual next step.
- Open reduction — surgery to remove the tissue blocking the socket — is used when a closed reduction will not hold.
Needing the next step is not a failure of your care or your baby's. It reflects how the hip was formed, and treated hips that follow this route still very commonly end up normal.
