Detection Of Developmental Dysplasia Of The Hip Research Articles

Utility of Clinical and Ultrasonographic Hip Screening in Neonates for Developmental Dysplasia of the Hip.

Developmental dysplasia of the hip (DDH) is a musculoskeletal condition occupying any point along a spectrum of anatomical abnormalities that alter the stability of the newborn hip. Presentation varies throughout infancy and the majority of cases, especially those that are mild in nature, tend to resolve without intervention. An analysis of outcomes was conducted on infants born over a two-year period at a single-center, community hospital in East Toronto. The unwritten norm at the institution has become to order hip ultrasonography for all infants born in the breech position through C-section. Given the healthcare expenditure associated with routine radiographic screening, a careful analysis was undertaken to ascertain whether this screening regimen was effective in preventing late-stage detection of advanced DDH and improving organization in patient management. There were a total of 4236 babies delivered over the two years. One-hundred sixty-four (164) babies were born breech and through C-section. Eight (8) babies had abnormal hip examinations, one of whom was ultimately diagnosed with DDH. Forty-six (46) babies showed abnormal hip ultrasound at six weeks. Seventeen (17) referrals were made to the orthopedic surgeon. This resulted in a total of seven cases of DDH being diagnosed over the two years. The sensitivity and specificity of clinical hip screening were 14.3% and 95.5%, respectively, while that for ultrasound screening was 100% and 75.2%.To improve the quality of care and detection of DDH, a risk factor analysis was conducted to retrospectively analyze which DDH cases would have been missed if a higher threshold to ordering hip ultrasonography had been used. Based on the test characteristics of clinical and ultrasonographic screening, held in conjunction with the risk factor analysis results, an altered screening regimen was proposed with the intention of being just as sensitive but more cost-effective. This regimen integrates clinical screening using Barlow and Ortalani maneuvers until the eight to 10-week period and examines for limited abduction from eight weeks onward. Adjuncts like the Galeazzi test and that for asymmetrical skin folds should also be included to increase the sensitivity of clinical screening. Ultrasonography is proposed for high-risk individuals, with the criteria for stratification as high-risk being extracted from the risk factor analysis. Ultrasound is also proposed to be done in a serial fashion prior to orthopedic surgery referral in cases where the age of the infant allows, which serves to better evaluate the risk for lasting DDH and understand the longitudinal trajectory of the patient. This serves the additional purpose of decreasing the psychosocial burden on families. This can be particularly significant for infants for whom the initial abnormalities are due to self-resolve with the maturation of the hip joint and the infant’s growth.

Musculoskeletal ultrasound: a useful tool for diagnosis of hip developmental dysplasia: One single-center experience.

Developmental dysplasia of the hip (DDH) is one of the most common congenital abnormalities of the musculoskeletal apparatus in newborns. The aim of this study was to analyze the contribution of ultrasonography in the detection of DDH in newborns and infants, identifying the regional incidence of this pathology in the central area of Romania, emphasizing the risk factors that underlie DDH etiopathogenicity.This article represents a retrospective study of 847 newborns and infants examined in the Imagistic Department of a medical center from the central area of Romania, between January 1 and December 31, 2016. The ultrasound examinations were performed for the bilateral coxofemoral joints, using the method and technique described by Graf. For subjects born in the same medical center, data regarding mother's age, birth weights, and type of delivery (natural vs. caesarian section) were statistically analyzed.In our study group, the frequency of ultrasound diagnosis obtained from the examinations of right and left hips showed that the most frequent stage was type IA, and the rarest stage was III. The IA stage of right coxofemoral joints (87.3%) was higher than in the left coxofemoral joints (87.2%). The incidence of hip dysplasia (type III) diagnosed with ultrasound examinations in subjects from the central area of Romania was 0.2% (0.1% in both hips and 0.1% for the left coxofemoral joint).The musculoskeletal ultrasound examination is effective in early detection of hip dysplasia. The implementation of national and regional programs that promote indications, risk factors, and the screening age for DDH in both rural and urban areas could be a step forward in the early diagnosis of hip dysplasia for newborns and infants. The low incidence of DDH from our study group is not able to identify the role of advanced age of the mother, high birth weight of the newborn, or caesarean section as risk factors involved in the etiology of hip dysplasia. The implementation of national and regional programs that promote the musculoskeletal ultrasound as a screening imagistic investigation for DDH, in both rural and urban areas, could be a step forward in the early diagnosis of hip dysplasia for newborns and infants.

The Impact of the Implementation of a New Selective Screening Program for Neonatal Hip Ultrasound in Cardiff and Vale University Health Board

Objective: Developmental dysplasia of the hip (DDH) is a common and preventable cause of disability. Early detection of DDH (<3 months) is associated with reduced risk of surgical treatment, hence in addition to the traditional clinical screening, NIPE guidelines advocate the use of selective screening of those with DDH associated risk factors. In 2016, Cardiff and Vale University Health Board (CAVUHB) implemented a selective screening program for DDH. This research will determine the impact and up-to-date cost effectiveness of a selective screening for DDH. Methods: A retrospective study of all patients born between 1st of January 2016 and the 31st of December 2016, who underwent ultra-sonographic screening for DDH in CAVUHB. Ultrasounds were graded using Graf’s classification, treatment outcomes were determined by patient’s records and costings were based on 2016 NHS tariffs. The research took place at the University Hospital of Wales (UHW). Results: Screening of those with risk factors for DDH, but a normal examination diagnosed 72% of all DDH cases and 38% of treated DDH cases. Screening for risk factors cost CAVUHB £98914, with a cost per favorable outcome, defined as early detection and successful treatment of DDH without surgical intervention, of £12364. The mean cost of DDH treatment of a patient missed by screening was £14431. All DDH cases were detected through breech presentation or family history risk factors. Screening only those with these risk factors is more cost effective and equally successful with a cost per favorable outcome of £9095. Conclusion: The selective screening program was successful and cost effective in detecting and treating cases of DDH. However, the screening process can be made more cost-effective without reducing DDH detection rate, by omitting statistically insignificant risk factors from the screening criteria. Early detection of DDH is important for effective treatment. CAVUHB cost-effectively reduced morbidity and potential surgical mortality within the neonatal population because of its selective screening program for DDH.

RELIABILITY AND VALIDITY OF CLINICAL AND ULTRASOUND EXAMINATIONs OF DEVELOPMENTAL DYSPLASIA OF THE HIP

Developmental dysplasia of the hip (DDH) is the most common congenital deformation of the musculoskeletal system and its successful treatment is closely related to early diagnosis. The study is aimed at examining the incidence of developmental dysplasia of the hip (DDH) and at analysing the validity of clinical examination, which is used for the early detection of DDH in the neonatal period, compared to ultrasound examination. The study involved 400 neonates born in the Banja Luka Region. A new questionnaire was open during the first regular ultrasound and clinical examination of the neonates’ hips and anamnestic and clinical data were recorded in it: the asymmetry of the gluteal, inguinal and femoral folds (Bade sign), the result of abduction test separately for each hip, the Ortolani sign of luxation and the Palmen sign of reposition, then hip sonography. A Toshiba ultrasound machine with a 7.5 MHz linear probe was used. The method employed was Professor Reinhard Graf’s. Out of the total number of the children with a positive sonographic finding for DDH, 63.16% of them have one of the clinical signs of DDH. The ability of a clinical finding to identify those patients who do not have DDH and have a negative sonographic finding is 79.8%. Out of the total number of the examined children with a positive clinical finding, only 15.58% of them also have a positive sonographic finding for DDH. This research has showed that clinical examination of the hips is of low sensitivity, specificity and reliability, and that not all types of DDH can be detected. Clinical examination must remain an integral part of every infant’s examination, but it constitutes a complementary diagnostic procedure to ultrasound examination. The ultrasound examination of DDH has created new possibilities and has filled the void that existed due to the deficiency of clinical tests, and at the same time it has reduced the number of X-ray examinations of the hips. This research has confirmed that clinical examination of the hips does not meet the screening criteria. It must remain an integral part of an infant’s examination because it, among other things, provides the information which enables the orthopaedic surgeon to choose the most beneficial therapeutic procedures in DDH treatment.

The role of clinical examination and risk factors in the diagnosis of developmental dysplasia of the hip: a prospective study in 188 referred young infants.

In this prospective study, the role of clinical examination and risk factors in the diagnosis of developmental dysplasia of the hip (DDH) was analysed. For this purpose, 376 hips of 188 referred infants with an average age of 3.7 months (range 0-8 months) were clinically and ultrasonographically (Graf method) examined. Infants who had at least one risk factor for DDH had a three times higher occurence rate of DDH than those who didn't have any. Breech presentation and positive family history were the two most common risk factors associated with DDH. The rate of DDH was nearly 16 times higher in the hips with at least one abnormal clinical finding than in the ones without any. Ultrasonographically unstable hips (type IIc-unstable to type IV) were always detected during clinical examination. There was a risk of missing the diagnosis of hips with acetabular dysplasia alone. Limitation of abduction and asymmetry of the skin folds were the two most common clinical findings associated with DDH. Nearly two-thirds of the infants with at least one positive clinical finding and at least one risk factor had either an unilateral or bilateral dysplastic hip. It was concluded that a careful clinical examination was significantly more important than the coexisting risk factors in the detection of DDH.
