Shoulder Spica Cast Care


What is the purpose of a shoulder spica cast?

A shoulder spica cast is used to stretch a tight shoulder after a botulinum toxin injection or to hold a child’s shoulder in position after tendon transfer surgery while the body heals.If your child is big enough, we will make the belly portion of the cast ahead of time while your child is standing up. After the fiberglass hardens, we will remove the belly band and then reapply it later in the operating room.

How do I care for my child while in a shoulder spica cast?


  • DO NOT place your child in a bathtub or sink – sponge bathe only!
  • Place plastic bags over the cast and use adhesive tape for the edges to keep it dry while sponge bathing
  • Check your child’s skin at bath time
  • Look for rub spots commonly found between the thumb and index finger and on the back of the belly band – cast padding can compact and move, leaving sharp edges
  • If you find sharp edges, place mole skin or other padding between your child and the cast to protect the skin


Cover the cast with a towel while eating to avoid soiling

How to dress a child in a cast


  • Wear big T-shirts or tank tops
  • Oversized zip-up sweat shirts work well to keep warm

Car Seat:

  • Bring your car seat on the day of surgery
  • Most children fit in their car seat without any modifications
  • Support your child’s head, neck and back (above the waist band), with a towel or blanket if needed for comfort
