Although atlantoaxial rotatory fixation (AARF) is a common cause
of torticollis in children, the diagnosis may be delayed. The condition
is characterised by a lack of rotation at the atlantoaxial joint
which becomes fixed in a rotated and subluxed position. The management of
children with a delayed presentation of this condition is controversial.
This is a retrospective study of a group of such children. Children who were admitted to two institutions between 1988 and
2014 with a diagnosis of AARF were included. We identified 12 children
(four boys, eight girls), with a mean age of 7.3 years (1.5 to 13.4),
in whom the duration of symptoms on presentation was at least four weeks
(four to 39). All were treated with halo traction followed by a
period of cervical immobilisation in a halo vest or a Minerva jacket.
We describe a simple modification to the halo traction that allows
the child to move their head whilst maintaining traction. The mean follow-up
was 59.6 weeks (24 to 156).Aims
Patients and Methods
Obesity is thought to be an aetiological factor for slipped capital femoral epiphysis (SCFE). We analysed changes in the incidence of SCFE in Scotland over the last two decades. During this period rates of childhood obesity have risen substantially and evidence for a relationship between these changes and the incidence of SCFE was sought. We found that the incidence of SCFE increased from 3.78 per 100 000 children in 1981 to 9.66 per 100 000 in 2000 (R2 = 0.715): a two and a half times increase over two decades. It was seen at a younger age, with a fall in the mean age at diagnosis from 13.4 to 12.6 years for boys (p = 0.007) and 12.2 to 11.6 for girls (p = 0.047). More children under eight years old were seen with SCFE in Scotland in the decade to 2000 than in the previous decade (p = 0.002, R2 = 0.346). A close correlation was observed between rising childhood obesity over the last 20 years in Scotland and an increasing incidence of SCFE.
Peripheral limb ischaemia is rare in children. We have treated only 12 infants and children with this condition in the past 15 years at the Royal Hospital for Sick Children in Glasgow. There were nine neonates and three older children. Most were suffering from life-threatening illnesses or severe infection. Two were born with ischaemic arms with no apparent cause. We have analysed the factors leading to ischaemia, the outcome of the initial treatment and the later orthopaedic problems. Two required amputation of both legs, one of an arm, two of feet and one of toes. Two had skin grafts. All surgery was performed after demarcation was well established and delayed closure was used after amputation. Five children developed limb-length discrepancy or an angular deformity. To date two have required additional corrective surgery.
