About this study
Official title: Structural and Functional Sequelae of Developmental Dysplasia of the Hip
The aim of this study is to assess long term effects of developmental dysplasia of the hip (DDH) to overall health and quality of life later in life. We compare hip radiographs, hip symptoms, clinical examination, head asymmetry, dental examination and intraoral scans of 170 children and young adults treated for DDH in their childhood with age and sex matched controls.
Read the detailed description
Developmental dysplasia of the hip (DDH) is the most common musculoskeletal disorder in infancy. However there are few reports of long term effects of successfully treated DDH. Incidence of DDH in neonatal period is approximately 1-10/1000 depending on screening protocols used, the age of the infant during screening and which ultrasonographic findings are considered normal and which DDH. The prevalence of hip dysplasia in adult population is grossly 4 % when using Wibergs Centre-Edge (CE) ≤ 20° as definition of dysplasia. It is still unclear, what is the relation between adult acetabular dysplasia and developmental dysplasia in children. Hip dysplasia overall is a major contributing factor in hip osteoarthrosis and total hip replacement in young adults.

Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 29 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Finland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Wibergs Centre-Edge Angle (time frame: 10 - 30 years after DDH has been treated). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Nov 2023; AzTrials last refreshed its copy on 7 Nov 2026.
