[Early clinical and radiological basic detection of congenital hip dysplasia at primary health care units].

The number of cases of late congenital hip dysplasia has increased, together with its sequelae, disability and absence of early diagnosis. The problem is that there is a difference between the sensitivity and the clinical exam, and the physicians knowledge of this topic is poor. We evaluated the quality of the training provided to the primary health care staff on congenital hip dysplasia. A prospective cohort study was undertaken to study 228 physicians for 3 years. A workshop was delivered and the physicians took a pre-workshop and a post-workshop exam. Then pelvic X-rays of infants under 6 months of age were taken and the X-ray references and measurements were assessed. The statistical analysis assesses the change in the pre-workshop and post-workshop grades in both the group that participated in the workshop and the group that did not. The statistical variables used included means, standard deviation, minimum and maximum grades, and the score differences. Students t test was used to prove the statistical significance of the differences, with n-1 degrees of freedom. Thirty-one pathological hips were detected in infants under 6 months of age in the group that took the workshop. The group that received the training shows that the latter may have a positive impact since an improvement in the grades (p 0.0001) was seen after the theoretical and practical course and after the X-ray measurements. A low knowledge level was observed. The training raised the awareness of the health care staff and a progressive increase was seen in the number of infants under 6 months of age who received a timely detection.
