Background: Periacetabular osteotomy (PAO) has become a popular procedure for re-orientation of the acetabulum in patients with a developmental pathomorphology. Since its first description by Reinhold Ganz in 1988, many institutions worldwide have adopted the procedure for the treatment of developmental hip dysplasia (DDH) and have subsequently reported their results. The aim of this study was to provide a meta-analysis of the likelihood of long-term survival of a dysplastic hip after PAO. Methods: A systematic literature review was conducted using Medline, Cochrane and “Web of Science” databases to identify articles reporting survival estimates for PAO in patients with DDH. To be included in the analysis, studies had to include patient cohorts aged <40 years, with Osteoarthritis grade < Tönnis III and no form of neuromuscular dysplasia. Adjustment for cohort overlap was performed. Quality assessment included level of evidence (LOE) according to the oxford center for LOE criteria and the “Methodological index for non-randomized studies (MINORS)”. After data extraction, a random-effects meta-analytical model was applied to provide weighted mean estimates of survival at 5 years, 10 years, 15 years and 20 years. Results: Nine relevant articles included 2268 dysplastic hips that underwent PAO in 9 institutions. Of the included studies, 5 presented level III evidence and 4 presented level IV evidence. The MINORS score was 11 for 3 studies, 12 for 4 studies and 13 for 2 studies. The 5-year survival after PAO was 96.1% (95% CI, 94.9–97.3), the 10-year survival was 91.3% (95% CI, 87.7–94.8), 15-year survival 85.0% (95% CI, 78.9–91.1), 20-year survival 67.6% (95% CI, 53.9–81.3). Conclusions: The results provide a representative survival estimate of a dysplastic hip after PAO based on global evidence. This should provide clinicians and patients with an adequate reflection of prognostic expectations after this kind of surgery.

Long-term follow-up studies on children with surgically treated developmental dysplasia of the hip (DDH) have shown that not only the affected side progresses to premature osteoarthritis, but the unaffected side may also suffer from insidious hip dysplasia or osteonecrosis. The current gait analysis study identified the loading and unloading rates of the ground reaction forces (GRF) and lower limb joint axial forces during gait, and their correlations with the hip morphology in twenty juvenile patients with surgically treated unilateral DDH during toddlerhood. In a gait laboratory, each subject walked at preferred speed on a 10-m walkway while the kinematics and the GRF were measured. Loading and unloading rates of the vertical GRF and the joint axial forces were obtained as the maximum instantaneous slope of these force curves. Radiographic measurements of the hips were taken, and the correlations between the morphological parameters and the loading and unloading rates were obtained. The patients showed greater-than-normal peak loading rates of the joint axial forces, and the loading rates on both the affected and unaffected sides were strongly correlated to the acetabular index on the unaffected side, which was also significantly correlated with the peak unloading rates on the affected side. These results suggest that apart from regular follow-up of the affected hip, routine assessment of the morphological changes and/or increased loading rates on the unaffected hip is also important for early identification of any signs of insidious hip dysplasia and risk of premature degeneration of the cartilage.

Abstract Introduction Without a prompt diagnosis, developmental dysplasia of the hip (DDH) in infants can lead to severe sequelae. Current screening strategies emphasize the use of Ortolani and Barlow physical examination manoeuvres, yet they exhibit low sensitivity. The purpose of this study is to evaluate the performance of a new physical examination tool (the pronation manoeuvre) as a screening tool for DDH. Methods To evaluate the new manoeuvre, a cross-sectional and analytic study was performed with a nonprobabilistic sampling method. Patients with either a positive Ortolani or Barlow manoeuver were evaluated with the new manoeuvre and hip ultrasound. Controls were infants with negative Ortolani, Barlow and pronation manoeuvres and also had ultrasound performed. Results DDH was confirmed in 83 of 130 cases (64%) and 2 of 130 controls (2%). The new pronation manoeuvre had a sensitivity of 76% and a specificity of 94% as compared to the Ortolani and Barlow manoeuvres (sensitivity 31 to 32%, specificity 93 to 100%) (P&lt;0.05). Conclusion This new physical examination manoeuvre could serve as another clinical tool for the initial screening of DDH in newborns. Its promising results against traditional screening procedures might potentially impact diagnosis and prognosis for patients with DDH.

Developmental Dysplasia of the Hip (DDH) includes a broad spectrum of hip abnormalities. DDH requires early diagnosis and treatment; however, no international consensus on screening protocol and treatment is provided in the literature. Epidemiological studies are helpful to understand the national variation of a specific surgical procedure and compare it with that of other countries. Data provided by different countries could allow researchers to provide international guidelines for DDH screening and treatment. Limited data are reported regarding trends of hospitalization for DDH, and no public database is available. The purpose of this study was to estimate annual admissions for DDH in Italian patients from 2001 to 2016, based on the hospitalization reports. Data of this study were collected from the National Hospital Discharge Reports (SDO) reported at the Italian Ministry of Health. Descriptive statistical analyses were performed. From 2001 to 2016, 3103 hospitalizations for DDH were recorded in Italy, with a mean incidence of 2.33 (per 100,000 young inhabitants). Females of the 0–4 years old group represented the majority of patients hospitalized for DDH.

Introduction The possibility of gradual closed reduction of hip dislocation in children over 1.5 years old is considered doubtful. Purpose Analysis of long-term results of applying the Ilizarov technique of gradual closed reduction in combination with the reconstruction of the hip joint components. Methods The outcomes of treatment of 62 children (81 joints) with congenital hip dislocation in the follow-up period from 5 to 16 years were studied. The treatment method included closed reduction of the dislocation using the technology proposed by G.A. Ilizarov and subsequent reconstruction of the joint components. The patients are divided into two groups based on their age. The first group included 33 patients (43 joints) under the age of 5 years. The second group consisted of 29 patients (38 joints) aged 5–8 years. Results Closed reduction failed in five cases. The recurrence of dislocation after closed reduction was 5.3 %. The rate of aseptic necrosis after closed reduction was 9.7 %. Good functional outcomes were reported in 87.7 %. They were significantly better in the younger group. The proportion of good anatomical results did not depend on age and was 77 % in general. Poor results were obtained in 8.8 %. Conclusion The anatomical and functional outcomes and the number of complications by using the technique described were comparable to other methods of gradual closed reduction of hip dislocation. But the technique we have described expands the age restrictions for its use.
