Incidence of congenital dislocation of the hip in Shiraz

ABSTRACT

During an eight month prospective study, 8240 newborns were examined for detection of congenital dislocation of the hip from Oct. 23,1991 to June 22, 1992. On first examination we found 1302 neonates [158/1000 live births] to have abnormal hips; 1063 [81.6%] were prone to subluxation [subluxatable], 218 [16.81%] prone to dislocation [dislocatable], 17 [1.3%] were dislocated and 4 [0.3%] were teratologic. The newborns with abnormal hips were followed in a neonatal OPD held for this purpose. After the sixth month of life 1272 [97.7%] of the neonatally unstable hips had resolved spontaneously, leaving 30 hips with true congenital dislocation [3.6/1000 live births]
