[Application of the Graf method for diagnosis and early detection of hip dysplasia].

Introduction: Developmental hip dysplasia (DHD) is the most common disorder affecting pediatric hip; screening all neonates clinically, and using ultrasonography selectively for those babies who are at high risk is a widespread recommendation. our goal is to evaluate the impact that USG diagnosis and early treatment of DHD has had on the child population of our unit.

Material and methods: Retrospective, descriptive and cross-sectional study. Records of those children from one to six months of age, with a diagnosis of DHD, without distinction of sex, subjected to ultrasonographic tracking in the period from January 2018 to December 2019 were reviewed. A follow-up of six months was carried out in all patients, from the moment of diagnosis and the start of treatment with harness, weekly visits for relocation, as well as ultrasonographic revision every four weeks to monitor the treatment.

Results: 19 cases were reported from the left side (47.5%), 10 cases from the right side (25%) and 11 bilateral cases (27.5%). The main associated risk factors were: product of the first pregnancy, family history of DHD, pelvic presentation, female sex. The results were favorable with a continuous use of harness of 23 hours observing a satisfactory evolution in 99.2% of the patients.

Conclusion: With the results obtained we can analyze the considerable success rate of the hip clinic of our hospital with the realization of the ultrasound, we find a lower incidence of patients with pain, limitation of function, as well as satisfactory gait patterns.
