Looking after your child's hip spica

A hip spica (pronounced ‘spy-kah’) is a type of cast used to keep the hip or thigh still. This page from Great Ormond Street Hospital (GOSH) describes the different types of hip spica used, how to look after your child while they are wearing one and how we remove it. A hip spica is most commonly used after hip surgery, but can also be used following surgery or a break to the femur (thighbone). It is a hard shell made of plaster of Paris, fibreglass or polyester. It extends from the trunk of the body down to include one or both legs, with a gap left for toileting. The type of hip spica will be decided by the consultant depending on the type of surgery or treatment needed.

What to look out for

If your child complains about any of these or you have any concerns, call us immediately on the numbers at the end of this page

  • Their toes feel cold and look white or blue – this does not get better when they wriggle their toes
  • Moving their toes hurts or the cast feels too tight
  • Their toes swell up and do not go down after their legs have been raised
  • They get pins and needles or their leg goes numb
  • There is any oozing or wetness coming through the cast or an unpleasant smell as this may indicate a wound infection or pressure ulcer
  • The cast is rubbing or digging into their skin or they can feel a burning sensation as this may cause a pressure ulcer
  • The cast is getting loose and slipping
  • The cast cracks, breaks, becomes soft or crumbles
Things to remember when your child is in a hip spica

  • Always keep the cast dry at all times
  • Check the cast every day and report any problems to us immediately
  • Do not put anything inside the cast or use any talcum powder or creams near it


  • If your child is in nappies, check the nappy and change it more often than usual to reduce the risks of leaks. We will teach you the ‘double nappy’ technique on the ward.
• Use a smaller nappy, tucked into the cast at the front, side and back then use a larger sized nappy over the top of the cast to hold it all in place.

• You can watch the YouTube™ video (details at the end) for a reminder of how to do it

  • If your child is toilet-trained, we will discuss other ways of toileting with you.
  • Change your child’s position frequently to prevent pressure ulcers. We will give you a copy of our leaflet Treating and reducing the risk of pressure ulcers after leaving hospital. Their heels and the skin near the edges of the plaster will be most at risk when in a hip spica so check their skin regularly. We will show you various options for positioning your child before you go home.

Self care

  • It is important that your child's hygiene needs are met. You can use a damp flannel, sponge or baby wipes to wash your child (particularly their nappy area) – remember not to get the cast wet.

Moving and lifting your child

An occupational therapist will see you and your child before the operation (or they will talk to you on the telephone). They will talk you through specific details of caring for your child at home and how to move and lift them in a hip spica. This information will be tailored to your child's age, weight and abilities.

  • If you are carrying your child, hold them as close to your body as possible, and always lift with your knees bent and your back straight.
  • If your child’s hip spica has a reinforcement bar – never use this to lift or move your child.
  • Follow the instructions from your child's consultant - we will explain them to you after the hip spica has been applied.

Removing the cast

We will arrange an appointment for your child's cast to be removed.

We use three different tools to take it off:

  • An oscillating saw
  • Cast spreader
  • Bandage scissors
  1. The oscillating saw works with a side-to-side movement and not in a circular motion so it feels more like a vibration while grinding through the outer part of your cast. It is very noisy so you might want to wear headphones.
  2. We use bandage scissors to cut through the padding and stretchy stocking – the scissors have blunt ends so they won’t cut your skin.
  3. We use a cast spreader to widen the opening in the cast made by the oscillating saw.
  4. We will show you the tools before we start to remove your cast – you may be able to help us remove the cast if you want.

Did you know? Casts date back to the Ancient Egyptians – they used flour, eggs and animal fat to make a hardened cast – that must have been smelly! A more modern cast was developed by Ambroise Pare in the 16th century – this was made of wax, cloth and cardboard Plaster casts, made from gypsum plaster (known as plaster of Paris) was first used in the 19th century in hospitals In the last 30 to 40 years, new materials have been developed, such as fibreglass, polyester and rubber, that are lighter and stronger – and also come in different colours!
