When teaching family about a spica cast for DDH, which statement about the abduction stabilizer bar is correct?

• A. It can be adjusted to a position of comfort
• B. It is used to lift the child
• C. It adds strength to the cast
• D. It is necessary to turn the child

Answer: (C)

The abduction stabilizer bar is there to keep the hips in the correct abducted position and to stabilize the cast so the immobilization remains effective. By maintaining the legs apart and preventing inward rotation, the bar helps preserve alignment and the overall integrity of the spica cast. It should not be adjusted for comfort, used to lift the child, or relied on to turn the child; turning and lifting should be done with proper techniques and equipment as taught by the clinician. Emphasize to the family the importance of keeping the bar in place, monitoring skin and cast integrity, and avoiding any movement that could disrupt the hip alignment.
