Traumatic hip dislocation in children is an uncommon injury and constitutes an orthopedic emergency. We herein present a traumatic posterior dislocation of the hip in a 4-year-old child and emphasize on the role of early correction of the injury, preferably within 6 h since its occurrence to prevent long-term complications such as osteonecrosis, coxa magna, and osteoarthritis.

A 4-year-old boy, escorted by his mother, presented to our emergency room with pain, deformity, and swelling of the left hip following immediate fall from a tricycle. On examination, patient was unable to move his left lower limb actively. The affected limb was internally rotated, adducted, and flexed at knee with obvious shortening [[Figure 1]a]. Distal neuro-vascular status was intact. A plain roentgenogram of the pelvis favored the diagnosis of posterior dislocation of the left hip without any fracture [[Figure 1]b]. Patient was transferred to the emergency operating room for a closed reduction of the hip under general anesthesia. Post reduction X-ray taken on Thomas splint confirmed reduction of the hip without any fracture [[Figure 1]c]. Following successful reduction, hip spica cast was applied for 6 weeks with position of the hip maintained in abduction and extension. The patient returned for follow-up at 6 th week as advised and the cast was then removed. The hip appeared stable, and movements were painless. The child was permitted to walk. There were no clinical or radiological signs suggestive of avascular necrosis (AVN).

Traumatic hip dislocations (THD) are rare and represent 2-5% of all dislocations in all age groups  . Although 25 times less commonly seen in children under 14 years of age , , and constituting only 5%, or 0.8 cases per million of all the cohort of THD , , prompt identification of the injury is essential for a definitive early correction. Early reduction, preferably within 6 h of injury as followed in our patient, drastically reduces the potential of developing AVN by 20 folds , . Delay in management could impact prognosis and lead to the development of long-term complications such as osteonecrosis, coxa magna, and osteoarthritis in such patients.
