Interspinous distance in congenital dislocation of the hip
1Department of Orthopedics, Osmangazi University Hospital, Eskisehir, Turkey.
Insights
Radiographic measurements of interspinous distance in children revealed age-dependent increases in normal subjects but not in those with hip dislocation. This bony parameter is a better indicator for Salter
Area of Science:
- Pediatric Orthopedics
- Radiology
- Developmental Anatomy
Background:
- Congenital dislocation of the hip (CDH) is a developmental abnormality requiring timely surgical intervention.
- Salter's innominate osteotomy is a common surgical procedure for treating CDH.
- Determining the optimal age for this surgery is crucial for successful outcomes.
Purpose of the Study:
- To investigate the relationship between interspinous distance and age in children with and without CDH.
- To identify a reliable radiographic parameter for indicating the lower age limit for Salter's innominate osteotomy.
Main Methods:
- Radiographic measurement of interspinous distance was performed.
- Two groups of children were studied: 50 normal children and 50 children with CDH.
- Interspinous distance was analyzed in relation to chronological age in both groups.
Main Results:
- In normal children, interspinous distance increased proportionally with age.
- In children with CDH, interspinous distance did not show a similar age-dependent increase.
- A significant difference in the growth pattern of interspinous distance was observed between the groups.
Conclusions:
- Interspinous distance is a valuable bony parameter that reflects skeletal maturity in children.
- This radiographic measurement is a more suitable indicator for the lower age limit for Salter's innominate osteotomy than chronological age alone.
- Utilizing interspinous distance can help optimize surgical timing for congenital dislocation of the hip.
Abstract:
We measured radiographically the interspinous distance in 50 normal children and in 50 children with congenital dislocation of the hip. The value increased proportionally with age in normal children, but not in those with congenital dislocation of the hip. Our results indicate that a bony parameter, rather than the age of the child, is suitable for the indication of lower age limit for Salter's innominate osteotomy.
