Study Design:
A case of a bisegmental rotational fracture dislocation in the pediatric cervical spine is presented.
Objectives:
To highlight the problems in the diagnostics and surgical management of this rare type of injury.
Summary Of Background Data:
Fractures of the cervical spine are relatively uncommon in childhood. To the authors' knowledge, this is the first reported case of a bisegmental rotational fracture dislocation in the pediatric cervical spine managed by a combined anteroposterior approach.
Methods:
A 6-year-old girl was hit by a car as a pedestrian. In addition to an open fracture dislocation of the Lisfranc joint in the right foot, she sustained a bisegmental fracture dislocation at the lower cervical spine (C3-C5) with no neurologic deficit. The complete diagnosis of a locked rotational fracture dislocation could be established only by using computed tomography scans with three-dimensional reconstructions. The injury was managed with a combined anteroposterior open reduction and a bisegmental anterior fusion.
Results:
Implant removal was performed after bony fusion 6 months after surgery. At follow-up assessment 2.5 years later, the girl had a good radiologic result and a full and pain-free functional recovery.
Conclusions:
Bisegmental rotational fracture dislocations in pediatric cervical spines are not easily diagnosed and may require three-dimensional computed tomography scan reconstructions for complete assessment. In such rare cases, a combined anteroposterior surgical procedure may be indicated, with a bisegmental anterior fusion providing a good functional result.
