Insights

Bilateral simultaneous hip surgery in children with severe cerebral palsy improved hip movement, containment, and pain relief. This treatment enhanced patient handling and carer satisfaction, regardless of cerebral palsy subtype.

Area of Science:

  • Orthopedic surgery
  • Pediatric neurology
  • Rehabilitation medicine

Background:

  • Severe cerebral palsy affecting the entire body often leads to pelvic asymmetry, placing both hips at risk.
  • Hip involvement in cerebral palsy can result in pain, limited range of motion, and functional deficits.

Purpose of the Study:

  • To evaluate the efficacy of bilateral simultaneous combined soft-tissue and bony hip surgery in children with severe cerebral palsy.
  • To assess the impact of surgery on hip range of movement, symmetry, radiological containment, pain, handling, and function.

Main Methods:

  • A six-year retrospective clinical, radiological, and functional study.
  • Involved 30 children (60 hips) with severe, total-body cerebral palsy.
  • Surgical intervention included combined soft-tissue and bony procedures.

Main Results:

  • Early results (median 3-year follow-up) showed significant improvements in hip abduction and adduction in flexion.
  • Improvements were noted in fixed flexion contracture, radiological hip containment (Reimer's migration percentage, Wiberg's centre-edge angle), and pain relief.
  • Patient handling improved, with high carer satisfaction; no difference observed between dystonic and hypertonic groups.

Conclusions:

  • Bilateral simultaneous hip surgery is effective in improving hip mechanics and containment in children with severe cerebral palsy.
  • The surgical approach positively impacts pain, function, and ease of patient care.
  • Outcomes are consistent across different subtypes of cerebral palsy evaluated.
