We wished to examine the effectiveness of tibial lengthening
using a two ring Ilizarov frame in skeletally immature patients.
This is a potentially biomechanically unstable construct which risks
the loss of axial control. We retrospectively reviewed a consecutive series of 24 boys and
26 girls, with a mean age of 8.6 years (4 to 14), who underwent
52 tibial lengthening procedures with a mean follow-up of 4.3 years
(4.0 to 16.9). Tibial alignment was measured before and after treatment
using joint orientation lines from the knee and a calculation of
the oblique plane axis.Aims
Patients and Methods
We analysed the incidence of slipped capital
femoral epiphysis (SCFE) in South Australia, investigating possible associations
between an increased incidence of SCFE, the local indigenous population
and the Australian obesity epidemic during the last 20 years. Data
including race, age and gender were collected to obtain a profile
of the South Australian SCFE patient, and were then compared with
epidemiological data for South Australian adolescents. We concluded
that the incidence of both obesity and SCFE is increasing. We also
noted that the median weight of SCFE patients has increased and
the mean age at diagnosis has decreased. Despite weight profiles
comparable with those of the general population, we noted that an
indigenous child was three times more likely to develop SCFE than
a non-indigenous child. As far as we know there is no published
literature on the predisposition of Aboriginal Australians to SCFE.
