Insights
Skull bone ossification differs in children with developmental dysplasia of the hip (DDH) compared to healthy peers. Fontanel ossification showed no significant difference between the groups.
Area of Science:
- Pediatric Orthopedics
- Developmental Biology
- Craniometry
Background:
- Developmental dysplasia of the hip (DDH) is a common pediatric condition affecting hip joint development.
- Cranial bone ossification patterns may be influenced by various developmental factors.
- Understanding these patterns can provide insights into the broader skeletal development of children with DDH.
Purpose of the Study:
- To compare cranial bone ossification in female children diagnosed with DDH versus healthy controls.
- To investigate potential differences in head circumference and anterior fontanel patency.
Main Methods:
- A cohort of 56 female DDH patients and 60 healthy females (18-36 months) were analyzed.
- Measurements included age, head circumference, weight, height, and anterior fontanel patency.
- Statistical analysis compared anthropometric data and ossification parameters between groups.
Main Results:
- No significant differences were observed in age or weight between the DDH and control groups.
- Head circumference percentiles showed significant differences, with very low and very high ranges more frequent in the DDH group.
- Anterior fontanel closure and patency did not differ significantly between the groups.
Conclusions:
- While fontanel ossification is similar, cranial bone ossification patterns are distinct in children with DDH.
- These findings suggest potential broader skeletal development variations associated with DDH.
- Further research is warranted to explore the implications of altered cranial ossification in DDH.
Objectives:
This study aims to compare cranial bone ossification between patients with developmental dysplasia of the hip (DDH) and healthy individuals.
Patients And Methods:
Between September 2021 and April 2022, a total of 60 healthy female individuals (median age: 24.5 months; range, 18 to 36 months) and 56 female DDH patients (median age: 23 months; range, 18 to 35 months) were included. Age, head circumference, weight, height, and patency of the anterior fontanel were measured in groups. Percentiles were classified as very low, low, normal, high and very high. All patients were female and those with abnormal thyroid function test, vitamin D, calcium, phosphate and alkaline phosphatase values were not included in the study. For those diagnosed with DDH, they were included in the group regardless of the type of treatment.
Results:
No statistically significant difference was found between the groups in terms of age and weight (p>0.05). The very low and very high head circumferences were more frequent, and the normal head circumferences were less frequent in the DDH group (p<0.05). There was no significant difference between groups in terms of fontanel closure (p>0.05). In open fontanels, no significant difference was found in both groups in terms of age (p>0.05).
Conclusion:
Our study results showed no significant difference between the fontanel ossifications of children with and without DDH; however, we found that the ossification of the skull bones of children with DDH was different compared to healthy children.

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...
