Background:
Congenital muscular torticollis (CMT) is an orthopedic diagnosis
seen in childhood and presents within months after birth. In general the etiol-
ogy remains unknown. However medical textbooks suggest trauma at birth as
a main reason.
Purpose / Aim of Study:
The aim of this study was to systematically describe
obstetric outcomes in a population of children with a confirmed CMT diagnosis
Materials and Methods:
Children with a validated diagnosis of CMT born
at Aarhus University Hospital from 1993-2014 were included in the study.
Information on perinatal, intrapartum and neonatal characteristic were obtained
from databases and from medical records and systematically described.
Findings / Results:
In this study, there were no differences in birth characteris-
tics in children with left and right sided CMT, between boys and girls or between
the conservatively treated and the children who needed surgery. Four children
were in breech presentation, eighteen in vertex and two in unspecified cephalic
presentation. Of those born vaginally, five children were delivered by vacuum
extraction, and two children were assisted vaginal breech births. Five children
were delivered by cesarean section. The mean second stage of labour for the
vaginal deliveries was 32 minutes. Most of the children with CMT in this study
were delivered at term without signs of birth complications or trauma. None
experienced moderate or severe asphyxia.
Conclusions:
The results of the present study suggests that complicated birth
or birth trauma may not be the main cause of CMT and point towards intrauter-
ine and prenatal reasons for developing Congenital muscular torticollis.
