Research Article: A New Test (Sacco Manni Test 3) of Congenital Dysplasia of the HIP: A Cross Sectional and Analytic Study

Purpose Or Objective: Without a prompt diagnosis, congenital dysplasia of the hip in newborns can lead severe sequelae. Current screening strategies emphatize the use of ORTOLANI and BARLOW tests, yet they exhibit low sensibility. The purpose of this study is to evaluate for a new test as a screening tool for congenital dysplasia of the hip. Methods: to evaluate the new test, a cross sectional and analytic study was performed with a non-probabilistic sampling method. Patients with either a positive ORTOLANI AND BARLOW TESTS were evaluated with the new test (Sacco Manni test 3) and hip ultrasounds. Controls were infants With negative ORTOLANI and BARLOW and SACCOMANNI TESTs and also had an ultrasound performed. Results: CONGENITAL dysplasia of the hip was confirmed in 83 to 130 cases (64%), and 2 of 130 controls (2%). The new test had a sensitivity of 76% and A specificity of 94% as compared to the ORTOLANI and BARLOW TESTS (sensitivity 31 to 32 %, specificity 93 to 100% (p inferior to 0,05). Conclusion: This new test could serve as another clinical tool for the initial screening of congenital dysplasia of the hip in in fans or newborns. Its promising results against traditional screening procedures might potentially impact diagnosis and prognosis for patients with congenital dysplasia of hip.
