Purpose: A prospective, epidemiological investigation was performed in the patients referred to our hospital with suspected developmental dysplasia of the hip (DDH).
Materials and Methods: Of the 121 patients referred from the primary healthcare institutions, with suspected DDH from January 2006 to December 2007, 82 patients who were able to be followed up for at least 2 years were enrolled in this study. Confirmation of the diagnosis was determined by patient history, physical examination, simple radiographs, and ultrasonography. Epidemiological investigation was performed in the total 82 cases which were referred from the primary healthcare institution and were confirmed as having DDH, and at least a 2-year follow up was performed in all these cases.
Results: Of the 82 cases, 56 cases (68.3%) were within normal limits (W.N.L.), 15 cases (18.29%) were confirmed as having DDH, and 11 cases (13%) were diagnosed with several different diseases other than DDH. Compared to the total 82 cases, the percentage of females, presence of family history was statistically higher in the cases confirmed as having DDH. However, the incidence of breech presentation was not statistically different between all cases. 61 cases were referred by pediatricians and 21 cases were referred by orthopedic surgeons to the primary healthcare institution, and the diagnostic rate of DDH was statistically higher in the cases referred by orthopedic surgeons (p>0.05).
Conclusion: The rate of confirmation of the suspected diagnosis of DDH would hopefully increase through the establishment of physical examination protocols or radiologic study and systematic training programs that could be applied in the primary healthcare institution.
