Although infrequent, a fracture of the cuboid can lead to significant
disruption of the integrity of the midfoot and its function. The
purpose of this study was to classify the pattern of fractures of
the cuboid, relate them to the mechanism of injury and suggest methods
of managing them. We performed a retrospective review of patients with radiologically
reported cuboid fractures. Fractures were grouped according to commonly
occurring patterns of injury. A total of 192 fractures in 188 patients
were included. They were classified into five patterns of injury.Aims
Patients and Methods
Unstable pelvic injuries in young children with
an immature pelvis have different modes of failure from those in adolescents
and adults. We describe the pathoanatomy of unstable pelvic injuries
in these children, and the incidence of associated avulsion of the
iliac apophysis and fracture of the ipsilateral fifth lumbar transverse
process (L5-TP). We retrospectively reviewed the medical records
of 33 children with Tile types B and C pelvic injuries admitted
between 2007 and 2014; their mean age was 12.6 years (2 to 18) and
12 had an immature pelvis. Those with an immature pelvis commonly
sustained symphyseal injuries anteriorly with diastasis, rather
than the fractures of the pubic rami seen in adolescents. Posteriorly,
transsacral fractures were more commonly encountered in mature children,
whereas sacroiliac dislocations and fracture-dislocations were seen
in both age groups. Avulsion of the iliac apophysis was identified
in eight children, all of whom had an immature pelvis with an intact
ipsilateral L5-TP. Young children with an immature pelvis are more
susceptible to pubic symphysis and sacroiliac diastasis, whereas
bony failures are more common in adolescents. Unstable pelvic injuries
in young children are commonly associated with avulsion of the iliac
apophysis, particularly with displaced SI joint dislocation and
an intact ipsilateral L5-TP. Cite this article:
