Incidence and Epidemiological Characters of Developmental Dysplasia of the Hip in Lianyungang: Based on Ultrasound Screening: A Retrospective Study

Abstract

Objective To explore the incidence and epidemiological characteristics of developmental dysplasia of hip (DDH) in Lianyungang and provide a basis for early detection, early diagnosis and early treatment. Methods Ultrasound screening was performed on aged 4–6 weeks to collect the incidence and epidemiological profiles of DDH. Graf hip ultrasound imaging was used for screening. DDH was diagnosed with a classification of ≥IIa − . Results Of the 9803 babies, 4999 were boys and 4687 were girls. There were 117 babies diagnosed with DDH, incidence rate of 1.19%. The incidence of DDH rate at left was higher than that at right (0.89%, 87/9803) vs (0.37%, 36/9803) and the difference was statistically significant (P < 0.001). Multivariate logistic regression analysis indicated that female (OR = 5.059, 95% CI: 3.012–9.109) and first child (OR = 1.871, 95% CI: 1.169–2.832) were the risk factors of DDH. Due to the small number of relevant cases and the absence of DDH cases, improper swaddling, abnormal amniotic fluid volume and confluent malformation could not be included for statistical comparison. Conclusion The incidence of DDH in infants aged 4–6 weeks in Lianyungang was 1.19% (117/9803). DDH was more prone to occur on the left side. Girl and first-borns were the risk factors of DDH.

Evaluation of Ultrasound Screening Method and Prevalence for Developmental Hip Dysplasia In The Central Anatolia

“…Studies on the incidence of DDH using various physical examination and imaging methods show rates ranging from 0.5% to 1.5% 2. Dongsheng Zhu's study in China analyzed the results of 9803 infants and reported a DDH incidence rate of 1.19% [8]. Çekiç et al [9] used the Graf USG method to screen 1162 infants in the western Mediterranean region and found an incidence rate of 1.36%.…”

Chiropractic rehabilitation in accelerated rehabilitation after total hip arthroplasty for Crowe type IV hip dysplasia

“…Femoral challenges include medullary canal stenosis, excessive anterior tilt, and high diaphragm-diaphragm angle with epiphyseal mismatch. [ 4 ] Domestic data show that the incidence of this disease ranges from 1.1‰ to 3.8‰, [ 5 ] and the pathogenesis has not been clearly determined, and is now mostly considered to be related to genetic and mechanical factors in clinical practice. [ 6 , 7 ] At present, many patients are under-recognized for DDH and are admitted to the hospital with CroweIV DDH.…”
