Which factor presents the most unique challenge when immobilizing an elderly patient on a long backboard?

• A. Naturally deformed bones
• B. Joint flexibility
• C. Patient disorientation
• D. Abnormal spinal curvature

Answer: (D)

Abnormal spinal curvature is the factor that most uniquely complicates immobilizing an elderly patient on a long backboard. In older adults, kyphosis, scoliosis, and other deformities are common, and a flat backboard doesn’t match those curvatures. For effective immobilization you need to maintain the spine in as neutral and aligned a position as possible from head to pelvis. When the spine is curved, forcing the patient to lie flat can press on protruding vertebrae, shift alignment, or mask injuries. That means you must contour the patient to the board with padding and supports, carefully position the head and neck to respect the curve, and secure without over-straightening or compressing any part of the spine. This requires thoughtful adjustments during transfer and securing, along with attention to pressure points and airway safety.

Other factors can influence immobilization but aren’t as central to the technique. Naturally deformed bones and reduced joint flexibility add complexity, but they don’t define the main adjustment you must make to accommodate the spine’s shape. Disorientation may affect patient cooperation, but it doesn’t change how you mold and secure the body on the backboard.
