[Dislocated hips in cerebral palsy (author's transl)].

Area of Science:

• Orthopedic surgery
• Pediatric orthopedics
• Cerebral palsy research

Context:

• Hip dysplasia (excentrated hips) is a significant concern in spastic children.
• Observations include 119 cases in 81 patients, predominantly under ten years old and non-ambulatory.
• Some older, ambulatory patients also presented with excentrated hips.

Purpose:

• To analyze the results of surgical procedures for hip dysplasia in spastic children.
• To emphasize the importance of a three-dimensional approach to managing excentrated hips.
• To highlight the necessity of early diagnosis and intervention.

Summary:

• Restoring muscle balance is crucial before pelvic or femoral osteotomy.
• Triple pelvic osteotomy is recommended for younger children to improve acetabular orientation, with infrequent complications.
• Chiari's osteotomy is indicated for older children.

Impact:

• Early diagnosis of muscle imbalance allows for correction with less invasive soft tissue procedures.
• Timely surgical intervention can improve hip joint congruency and function in spastic children.
• Understanding the age-specific indications for different osteotomies optimizes treatment outcomes.
