Abstract
The developmental dysplasia of the hip disease is in 1% of newborns, and it is a risk factor for dislocation of the hip; only 1 from 7000 newborns develops dislocation of the hip. Newborns were selected from public and private hospitals in Celaya, Guanajuato. Parents were asked to sign informed consent. Clinical maneuvers were applied for diagnosis of developmental dysplasia of the hip, on three consecutive occasions, two by the same investigator and the third by a different observer: Ortolani, Barlow, Piston, Galeazzi, Peter Baden, the comparative sound transmission test, and comparative sound transmission with extension/flexion test were applied. The diagnosis was confirmed with ultrasound of hip, technique Graf, I healthy hip, II functionally immature, III subluxation, and IV dislocation. Sample size was 8 affected hips and 56 healthy hips. Kappa for intra observer and inter observer reliability were measured; the validity was measured by sensitivity, specificity, positive and negative predictive values, using the ultrasound diagnosis as the gold standard. The sample consisted of 78 neonates hips with female’s predominance. With comparative sound transmission test was obtained Kappa intra observer 0.80, Kappa inter observer 0.93, sensitivity 45.45%, specificity 96.27%, positive predictive value 66.67% and negative predictive value 91.49%; with comparative sound transmission with extension/flexion, was 0.83, 0.92, 72.73%, 95.52%, 72.73%, and 95.52%, respectively. The tests compared the sound transmission help better diagnose developmental dysplasia disease of the hip.
Highlights
The developmental dysplasia of the hip (DDH) is common throughout the world; in particular, about 1% of births in Mexico present with DDH, evolution to dislocation hip, the rate only gets to be in 1:7000 in live births [1]
The DDH is classified into physiological immaturity, subluxation, luxable and dislocation; the clinical diagnosis is made with clinical maneuvers, as Ortolani, Barlow, Piston, Galeazzi, Peter Baden or limitation to abduction, but these maneuvers only detect subluxation, luxable or dislocation of the hips [2] [4], being undiagnosed infants or infants with physiological immaturity, which is a risk factor to evolve to subluxation, luxable or dislocation
For the intra-observer reliability for Ortolani, Barlow were regular with Kappa 0.53 and 0.59, respectively, were perfect for maneuvers Piston and Peter Baden (Kappa 1.00 for both), and very good compared sound transmission and transmission compared to extension/flexion tests (Kappa 0.93 and 0.92, respectively)
Summary
The protocol was reviewed and approved by Research Committee of Division of Health Sciences and Engineering, Campus Celaya Salvatierra University of Guanajuato and Research Committee and Bioethics Committee of Hospital General Celaya, of Ministry of Health from Guanajuato State
