Abstract Purpose In Middle Europe developmental dysplasia of the hip (DDH) has an incidence of up to 5.9 %. The rate of congenital hip dislocation as the worst complication of a growth disorder of the hip is between 1.5 % and 2.5 %. Among known risk factors of DDH are breech position, multiples, foot deformities and family history. The aim of this retrospective study was to investigate prematurity as a risk factor for developmental dysplasia of the hip (DDH). Materials and Methods The hips of 283 infants who were born before the 38th week of gestation or earlier, and those of 377 infants who were born after the 37th week of gestation, none of whom had other risk factors for DDH, were compared using the ultrasound technique according to Graf et al., within the first week after birth. Both hips of all infants were included in the study. Results Surprisingly, the difference in alpha angles between the two groups was statistically extremely significant, favoring the preterm infants. Moreover, we found a physiological curve of alpha angle development with a peak after the 31st week of gestation. The incidence of pathological dysplasia was not significantly different in the two groups. Conclusion Our results suggest that prematurity is not a predisposing factor for DDH, but rather is protective for hip development.

Dysplasia Of The Hip

Chapter 112 focuses on developmental dysplasia of the hip, which includes a spectrum of abnormalities ranging from a stable hip with a mildly dysplastic acetabulum to complete hip dislocation. Pathophysiology, clinical findings, and screening studies are explored. The pathophysiology is multifactorial including mechanical, genetic and hormonal factors. Imaging strategies, findings, and treatment options are also discussed. Screening US, which is the imaging modality of choice, is performed on infants with predisposing risk factors. Outcome is quite variable with many cases resolving spontaneously without treatment whereas others stabilize with acetabular dysplasia. Treatment options include immobilization and surgery. MRI is used for problem solving in postoperative patients.

BACKGROUND: Studies investigating the association between developmental dysplasia of the hip (DDH) and risk factors in Saudi Arabia are rare. OBJECTIVE: Investigate the association between DDH and several risk factors among Saudi children. METHODS: The medical records of 82 children born in or admitted to King Abdul Aziz Medical City in Riyadh, Saudi Arabia with clinical suspicion of hip dislocation (HD) were included. The association between DDH and the following risk factors was investigated: age < 3 y, female-gender, twinning, first-born child, C-section, breech presentation, prematurity, positive family history and presence of associated abnormalities. RESULTS: HD was confirmed in 73 (89%) children (Positive HD) and excluded in 9 (11%) children (Negative HD). Eleven (13.4%) children were excluded from the positive cases as it was confirmed that they have paralytic hip dislocation not DDH. DDH was confirmed in 62 children (75.6%). The Chi square test (χ2) and odds ratios (OR) revealed that the positive family history, female-gender, age < 3 years, and presence of associated abnormalities had significant associations with the presence of DDH with P values and OR equal 0.00 (16.4), 0.002 (3.1), 0.005 (2.6), and 0.04 (1.9) respectively. Breech presentation, twinning, first-born children, prematurity, and C-section were not associated with DDH with P values and OR equal 0.93 (1.1), 0.46 (0.4), 0.11 (0.4), 0.08 (0.3), and 0.002 (0.3) respectively. CONCLUSIONS: Positive family history, female-gender, age < 3 years, and presence of associated abnormalities had approximately 16, 3, 2.5, and 2 times increased risk for DDH.

Dysplasia Of The Hip

Hip joint ultrasonographic (US) imaging is the golden standard for developmental dysplasia of the hip (DDH) screening. However, the effectiveness of this technique is subject to interoperator and intraobserver variability. Thus, a multi-detection deep learning artificial intelligence (AI)-based computer-aided diagnosis (CAD) system was developed and evaluated. The deep learning model used a two-stage training process to segment the four key anatomical structures and extract their respective key points. In addition, the check angle of the ilium body balancing level was set to evaluate the system’s cognitive ability. Hence, only images with visible key anatomical points and a check angle within ±5° were used in the analysis. Of the original 921 images, 320 (34.7%) were deemed appropriate for screening by both the system and human observer. Moderate agreement (80.9%) was seen in the check angles of the appropriate group (Cohen’s κ = 0.525). Similarly, there was excellent agreement in the intraclass correlation coefficient (ICC) value between the measurers of the alpha angle (ICC = 0.764) and a good agreement in beta angle (ICC = 0.743). The developed system performed similarly to experienced medical experts; thus, it could further aid the effectiveness and speed of DDH diagnosis.

Aim. Risk based screening for developmental dysplasia of the hip (DDH) with ultrasound is common. However, risk factors vary from one country to the other since data are insufficient to give clear recommendations. We aimed to evaluate the risk factors for developmental dysplasia of the hip (DDH). Methods. In this retrospective case-control study, the health records of all children, who were followed up between 2004 and 2014 at a well-child unit, were investigated for the diagnosis of DDH in Turkey. Of 9758 children, 57 children were found to have abnormal ultrasonographic findings (according to Graf classification) and these constituted the case group. As the control group, healthy 228 children who matched the case children in birth months were selected. Two groups were compared for the risk factors. Results. A total of 19516 hips of 9758 children were examined for DDH. 97 hips of 57 children were found to have abnormal ultrasonographic findings. When the two groups were compared, breech presentation, multiple pregnancy, and torticollis were identified as risk factors. The female sex was also found to have a significantly high prevalence among the children in the case group. Limited hip abduction, positive Ortolani, and Barlow signs were important clinical findings in the case group. Conclusion. According to our findings, breech presentation, female sex, torticollis, and multiple pregnancy were found to be the risk factors of this disorder. Infants with these risk factors should be investigated carefully for DDH.

Purpose We aimed to revisit the correlation between the previously defined risk factors and the occurrence of developmental dysplasia of the hip (DDH) and to assess the influence of these factors on the ultrasonographic type of hip dysplasia according to the Graf’s classification in patients with DDH. Methods Data of healthy infants (mean age 33 days) who had bilateral mature (normal) hips (Graf type I) were compared with the data of infants (mean age 105 days) who were treated by abduction brace due to unilateral or bilateral DDH (Graf type IIa- and worse hips). Results Infants with at least one risk factor had a significantly higher rate of DDH than those with no risk factors (p < 0.001). Likewise, infants with more than one risk factor had a significantly higher rate of DDH than those with only one risk factor (p = 0.008). Family history, breech presentation and swaddling were found to be the three significant risk factors related to the development of DDH. Family history, swaddling and oligohydramnios were found to be the three significant risk factors correlated with a higher rate of unstable/decentred hip(s) (Graf types D/III/IV) in patients with DDH. Conclusion The risk of DDH significantly increases in infants who have more than one risk factor for DDH. Positive family history and postnatal traditional swaddling are the two main factors both in the aetiology of DDH and in development of a more severe hip dysplasia in patients with DDH. Besides, breech presentation increases the risk of development of DDH and oligohydramnios leads to development of a more severe hip dysplasia in patients with DDH. By introducing these four variables as ‘absolute risk factors for DDH’ to the selective newborn hip screening programmes, the sensitivity and specificity of these programmes may be optimized and the risk of delayed diagnosis may be lessened.

Purpose Asymmetric skin folds (ASFs) have been linked to developmental dysplasia of the hip (DDH) in select studies, leading to their inclusion in paediatric practice guidelines regarding orthopaedic referral for hip evaluation. The purpose of this study was to investigate the utility of isolated ASFs as a screening tool for DDH in a series of patient referrals evaluated at a single institution. Methods We performed a retrospective review of consecutive patients between 0 and 12 months of age referred to orthopaedic clinics for isolated ASFs. We recorded radiographic findings (acetabular inclination or alpha angle), diagnosis rendered and treatment administered. Results A total of 66 patients were included (mean age 6.4 months; 2.47 to 10.76). All patients received pelvic radiographs or ultrasound. In all, 36 patients (55%) were considered normal by their treating physician and 25 (38%) were considered dysplastic and underwent brace treatment. One hip with an isolated ASF was found to have a dislocated hip on radiograph prior to their initial orthopaedic visit. None of the patients in this study have required surgery to date. Conclusion Using ASFs as a reason for referral led to increased diagnosis of mild dysplasia resulting in orthotic treatment. Thus, in our particular clinical environment, isolated ASFs can be an indicator of mild dysplasia and warrant further workup or referral. Because treatment philosophies regarding recognition and treatment of mild dysplasia vary amongst centres, the value of screening with ASFs likewise depends on the treating orthopaedic surgeon’s threshold for treatment of mild dysplasia.

Dysplasia Of The Hip

Infection at the pseudoacetabulum in a patient with a high hip dislocation has not been reported previously in the English literature. We report a case of total hip arthroplasty in a 28-year-old female who presented to us with hip pain following debridement of the infected pseudojoint in a case of neglected developmental dysplasia of the hip. The infection was treated with thorough debridement and drainage. However, even after achieving complete infection control, this patient complained of disabling right hip joint pain. Total hip arthroplasty with subtrochanteric osteotomy was performed to relieve the pain and improve gait. After surgery, the patient's symptoms were relieved. We consider that in this case of acute pseudojoint infection simple arthrotomy and debridement combined with irrigation and drainage provide effective treatment. But muscle weakness and more increased joint laxity can cause hip pain even after infection control. So total hip arthroplasty is likely to be necessary after the infection has been controlled in a patient with a highly dislocated hip.
