Clinical Trial
Lower limb lengthening and deformity correction using the Fitbone motorized nail system in the adolescent patient.
Leg lengthening by an external fixation is associated with various difficulties. Pin-tract infections are commonly encountered, and muscle contractures and joint stiffness are additional complications associated with this method. Several researchers explored a purely intramedullary solution for leg lengthening since the 1970s. ⋯ Our results suggest that the difficulties commonly associated with external fixators can be reduced with this method. It also allows good angular correction in patients with mechanical axis deviation. These features combined with a short time of hospitalization make it a promising procedure for limb lengthening in adolescent patients.

Case Reports
Metachronous aneurysmal bone cyst in a 9-year-old boy: case report and review of the literature.
Aneurysmal bone cyst (ABC) is a locally aggressive, benign bone tumor that commonly affects children. Metachronous ABCs are rare, and have been described only three times in the literature. Here we present a fourth case in a 9-year-old boy who presented with an ABC of the scapula; 2½ years later he presented with a tibial ABC. We also review the literature and discuss the pathological and clinical characteristics of this lesion.
