Hip subluxation in children with spinal cord injury: Incidence and influencing factors

Hip subluxation is a common issue for children after a spinal cord injury (SCI). Their hips are still developing, so factors like paralysis, limited movement, and muscle imbalances can cause the hip to slip out of place. This study looked at the records of 146 children with SCI to see how often hip subluxation happens and what makes it more likely. They checked things like how old the children were when they got hurt, how long ago the injury was, and how severe it was. The study found that hip subluxation was more common in children who were younger when injured, had complete injuries, and had floppy lower limbs. The longer the injury duration, the higher the risk of hip subluxation.

• 1
  The incidence of hip subluxation increased with the injury duration, with no subluxation occurring within three months of injury, but more than 50% occurred after 36 months.
• 2
  The injury age of children with hip subluxation is smaller than that of children with normal hips, and there was a significant negative correlation between injury age and the incidence.
• 3
  Children with flaccid lower extremities were more likely to develop hip subluxation than those with spasticity unexpectedly.
