Treatments of traumatic hip dislocation in children and outcomes of short-term follow-up: case reports and literature review
- CLC:

- Abstract:
- Objective Traumatic hip dislocation is an orthopedic emergency caused by external forces.Due to the particularity of anatomical structure of hip joint,the incidence of traumatic dislocation of hip joint is lower in children than that in adults.Traumatic hip dislocation (THD) is often complicated by avascular necrosis of femoral head and traumatic osteoarthritis,requiring immediate and accurate evaluations and prompt reductions.Methods Retrospective analysis was conducted for 10 children of posterior THD from 2014 to 2018.There were 7 boys and 3 girls with an average age of 7.9(2-14) years at the time of injury and an average follow-up time of 20.9(12-35) months.Results At the last follow-up,eight children had no hip pain.One case presented with avascular necrosis of femoral head and traumatic osteoarthritis while another case had the symptoms of sciatic nerve palsy.Also one case of hip joint space widening recovered well in a later stage.According to the Harris score at the last follow-up,the outcomes were excellent (n=6),decent (n=2) and poor (n=2).Conclusion Combined with literature review,traumatic dislocation of the hip is less common in children and can occur at any age.Most cases developed posterior dislocation.Injury mechanism,timing of reduction and a combination of other injuries are correlated with the prognoses of THD.Reduction within 6 hours after injury should remain an objective target.CT or even MRI evaluation is necessary before and after reduction.At the same time,avascular necrosis of femoral head should be a focus of attention during follow-ups.
