Late diagnosis in congenital dislocation of the hip
Insights
Congenital hip dislocation incidence remained stable. Most diagnoses occurred by three months, with fewer cases diagnosed at walking age, indicating improved early detection of this hip condition.
Area of Science:
- Orthopedics
- Pediatric Medicine
- Public Health
Background:
- Congenital dislocation of the hip (CDH) is a significant pediatric condition.
- Early diagnosis and intervention are crucial for optimal outcomes.
- Understanding incidence trends and diagnostic delays is important for public health initiatives.
Purpose of the Study:
- To investigate the incidence and diagnostic patterns of congenital dislocation of the hip in Uusimaa county, Finland.
- To identify factors contributing to diagnostic delays.
- To assess the long-term outcomes of diagnosed cases.
Main Methods:
- Retrospective analysis of 115 children diagnosed with CDH between 1966-1975.
- Review of medical records and child welfare clinic examination data.
- Follow-up assessment of children in 1981 to evaluate outcomes.
Main Results:
- The incidence of CDH diagnosed after the neonatal period was 0.76 per thousand liveborns, with no decreasing trend observed.
- The average age at diagnosis was 3 months, with a decrease in diagnoses made at walking age.
- Delayed diagnosis was suspected in 23% of cases; by 1981, 66% were symptomless, 16% had minor residual signs, and 18% had unclear outcomes.
Conclusions:
- The incidence of congenital hip dislocation remained consistent during the study period.
- While early diagnosis is improving, further efforts are needed to address diagnostic delays.
- Long-term outcomes are generally favorable, but a significant proportion of cases still present with unclear outcomes.
Abstract:
In 1966-1975, congenital dislocation of the hip was diagnosed after the neonatal period in 115 children in Uusimaa county in southern Finland; the incidence was 0.76 per thousand liveborns. No decreasing tendency could be seen during the time of the investigation. In most children, the diagnosis was made during the first medical examination at the child welfare clinic at the average age of 3 months. The number of children diagnosed at walking age seemed to be decreasing. The numbers of boys and bilateral affections were smaller in this group than among cases diagnosed during the neonatal period. Dislocation was suspected in 23 per cent of the children even before the diagnosis was made. The reasons for the delay are given and discussed. In 1981, 66 per cent of the children were symptomless and no radiographic signs could be seen. Sixteen per cent of the children had minor residual signs with no need for follow-up, and in 18 per cent the outcome was still unclear.
