AB  - Torticollis  (wryneck)  is  a  head  position  whereby  the  ear  is  tilted  to  1  shoulder  and  the  chin  is  rotated  to  the  opposite  shoulder.  The  most  common  form  of  torticollis  is  known  as  congenital  muscular  torticollis  and  is  due  to  overpull  of  the  sternocleidomastoid  (SCM)  muscle.  This  deformity  is  typically  noted  within  the  first  2  to  4  weeks  of  life  and  almost  always  by  6  months  of  age.  The  incidence  of  congenital  muscular  torticollis  is  reported  to  be  approximately  3  to  5  per  1000  births.  Although  its  etiology  is  not  completely  understood,  the  condition  has  been  previously  linked  to  breech  presentation,  increased  infant  size,  difficult  forceps  delivery,  and  first-born  children.  Orthopedic  disorders  associated  with  torticollis  include  hip  dysplasia,  clubfoot,  and  metatarsus  adductus.
