Case ReportsTransepiphyseal fracture of the femoral neck with dislocation of the femoral head and fracture of the posterior column of the acetabulum in a child.
We describe a 15-year-old boy with a posterior dislocation of the hip, fracture of the posterior column of the acetabulum and separation of the femoral capital epiphysis. To our knowledge no previous case in a child has been reported. Such high-energy injuries are extremely rare, and a poor outcome is expected. We advocate early referral to a specialised tertiary centre, and the use of a modification of Delbet's classification to reflect the complexity and displacement which may occur with this injury.

Interobserver and intraobserver variation in the assessment of the healing of tibial fractures after intramedullary fixation.
The reliability of the radiological assessment of the healing of tibial fractures remains undetermined. We examined the inter- and intraobserver agreement of the healing of such fractures among four orthopaedic trauma surgeons who, on two separate occasions eight weeks apart, independently assessed the radiographs of 30 patients with fractures of the tibial shaft which had been treated by intramedullary fixation. The radiographs were selected from a database to represent fractures at various stages of healing. ⋯ The intraobserver agreement of the overall impression of healing (kappa = 0.89) and the number of cortices bridged by callus (kappa = 0.82) or with a visible fracture line (kappa = 0.83) was almost perfect. There are no validated scales which allow surgeons to grade fracture healing radiologically. Among those examined, the number of cortices bridged by bone appears to be a reliable, and easily measured radiological variable to assess the healing of fractures after intramedullary fixation.
