Abstract
Specific reports on congenital hip dislocation in West Africa arerare. During a prospective study conducted at Ouagadougou Universityteaching hospital from December 1996 to July 1997, 2514black newborn patients were examined. Their mean age was 1.64day; 46.5% were girls. First borns accounted for 31.74% of the series,while infants born from breach delivery represented 1.17%.Only 0.48% were twins.Limb anomalies represented 51.87% of all malformations. Twocases of congenital torticollis and one case of infantile scoliosiswere noted. No case of congenital hip dislocation was found in spiteof meticulous clinical evaluation and numerous hip ultrasonographies.One hundred and fifty three patients have been reviewedafter a median follow-up of 4.66 years. All were normal.One hypothesis states that, in many African countries, infants arecarried on their mother’s back with their hips positioned in flexionabduction.This would explain the absence of congenital hip dislocation.Our study fails to support this, because none of our newborns hadbeen carried on his mother’s back prior to our screening. We thinkthat genetic factors account for the absence of congenital hip dislocationin our countries.
