Reliability of the Barlow and Ortolani tests for neonatal hip instability.
OBJECTIVE: To investigate if those responsible for screening for neonatal hip instability are using acceptable manual hip stress tests as described by Ortolani and Barlow. METHOD: A video camera was used to record the technique of 35 personnel who were responsible for screening. They examined both a baby and a simulator. The study comprised five groups, classified by experience and practice: senior orthopaedic surgeons, senior paediatric staff, junior paediatric staff, nurses, community staff. RESULTS: The seven authors together with six independent expert observers viewed the video and marked the performance with the aid of a specially designed proforma. Although there was some variation between these expert observers, the results showed differences in the scores obtained by the different groups of examiners over all aspects of the test procedure. CONCLUSION: Video recording for critical analysis and feedback is a useful technique in this situation. Overall, the results suggest that testing for neonatal hip instability was inadequate. A variety of hip stress manoeuvres were being performed. The ability of each subject to perform satisfactory tests seemed to depend on their experience and education. More "hands on" training and experience of testing might provide the necessary competency for screening.

Hip screening: are health visitors adequately prepared?
Developmental dysplasia of the hip is a crippling disorder, causing early arthritis if left undetected. In Northern Ireland health visitors routinely screen infants' hips at specific intervals up to pre-school age. The screening tests used appear simple but involve a high degree of skill in order to identify abnormality. A video study of three health visitors found that their performance was poor, but a marked improvement was noted after a period of specialised training. Bernadette Trainor et al suggest that more initial training and post-qualification update sessions are necessary to support health visitors in this role.

Low-frequency vibration emitted from unstable hip in human neonate.
Developmental dysplasia of the hip (DDH) continues to be an orthopedic enigma. Some authors still believe it is a purely birth phenomenon. Even with widespread birth screening, however, DDH continues to become evident later than three months of age, long after a satisfactory outcome can be guaranteed. In an effort to reduce the number of late manifestations, the authors have developed a noninvasive form of screening for DDH called vibration arthrometry. Five hundred neonates were examined in local maternity hospitals, according to the guidelines of Ortolani and Barlow. The new method involves the attachment of miniature accelerometers around the infant's pelvis. Using this method, it was possible to elicit vibration events from approximately one fourth (255 hips) of the hips tested; vibrations were recorded from normal hips (125), from "clicky" hips (128), and from unstable hips (two). Differences between "nil-felt" (clinically silent) and "click-felt" (palpable clicking on testing) were significant. Vibration testing can be seen as an aid in the manual palpation necessary to detect this crippling condition.

Cost of treatment of congenital dislocation of the hip.
Early treatment for congenital dislocation of the hip is usually simple and inexpensive. However, if the disease is not detected by 6 months of age, treatment is often complicated and expensive. We evaluated the potential cost-saving of screening, by examining the costs in 36 late cases born in 1980 and found an average cost of pounds 6,674 per case for treatment to this date. This amount could justifiably be spent on each case detected in an effective screening programme.
