Developmental dysplasia of the hip in infants with congenital muscular torticollis

Am J Orthop (Belle Mead NJ). 2008 Sep;37(9):E155-8; discussion E158.


Infants with congenital muscular torticollis (CMT) are at increased risk for developmental dysplasia of the hip (DDH), which has led to increased use of diagnostic procedures. Our goal in this study was to establish indications for imaging the hips of infants presenting with CMT. We reviewed the cases of 292 patients with the diagnosis of CMT, 16 of whom were found to have DDH. Each patient with DDH had an abnormal clinical hip examination. Our study results demonstrate that, despite the association of these disorders, an infant presenting with CMT does not require routine hip imaging in light of a normal clinical hip examination. The coexistence rate for CMT and DDH requiring treatment is 4.5%, which is lower than the commonly accepted 20%.
