Traumatic dislocation of the hip in a child caused by trivial force for age

Hiroyuki Furuya et al. Case Rep Orthop. 2014.

Abstract

Traumatic hip dislocation in children has a relatively rare occurrence. There are some residual complications, such as avascular necrosis of the femoral head, growth disturbance caused by premature fusion, neurological injury, recurrent dislocation, and posttraumatic arthritis. There is no consensus in the literature about the period of non-weight bearing after reduction. A rare case of a 13-year-old boy of hip dislocation caused by trivial force for age is reported followed by review of the pediatric literatures with treatment recommendation.

Figures

Figure 1
Figure 1
X-ray shows that the left femoral head is laterally displaced to the acetabulum, which is consistent with posterior dislocation of the hip.
Figure 2
Figure 2
X-ray shows the affected side hip after reduction. The left femoral head is correctly positioned in the acetabulum.
Figure 3
Figure 3
Coronal (a) and axial (b) CT scan after reduction shows the left femoral head correctly positioned in the acetabulum with no fractures or interposition of osteochondral fragments.
Figure 4
Figure 4
Coronal T2 weighted image in MRI shows no evidence of avascular necrosis of the femoral head (a) and damage of soft tissue (b) at 3 days.
Figure 5
Figure 5
Coronal T2 weighted image in MRI shows no evidence of avascular necrosis of the femoral head (a) and healing of soft tissue damage (b) at 6 weeks.
