Traumatic posterior dislocation of hip in children

Area of Science:

• Orthopedic Surgery
• Pediatric Traumatology

Background:

• Traumatic posterior hip dislocation is an uncommon yet critical orthopedic emergency in children, representing over 80% of pediatric hip dislocations.
• In pediatric patients, this injury can result from minimal trauma due to acetabular pliability and ligamentous laxity, unlike skeletally mature adolescents who require greater force.

Observation:

• This review highlights two pediatric cases of traumatic posterior hip dislocation in a 3-year-old and a 14-year-old.
• Both cases involved prompt reduction of the hip dislocation within 6 hours of injury.

Findings:

• Early reduction of traumatic posterior hip dislocation within 6 hours is associated with favorable outcomes.
• At a 6-month follow-up, both patients exhibited normal examinations with no evidence of post-traumatic changes, underscoring the importance of timely intervention.

Implications:

• Prompt reduction of traumatic posterior hip dislocation in children is essential for minimizing long-term complications such as avascular necrosis and degenerative arthritis.
• While early reduction improves prognosis, there is no established consensus on post-reduction treatment protocols, necessitating further research.
