Definition: A hip spica is a special type of cast used to immobilize the hip joints and/or the thigh. Often this type of cast is used to promote healing of a damaged hip joint or fractured femur (thigh bone).

The hip spica will vary depending on the intended use, but it usually extends from the mid-chest down to below the knee. If the problem is on both hips or thighs, then the cast will extend past both knees, or if the problem is only on one side the cast will extend below one knee. A hole is left in the groin are to allow the child to use the bathroom or for diapers to be changed.
