[Anatomic study of parietal bone for use as bone graft material]
1Stomatological College, Fourth Military Medical University, Xian.
Summary
Parietal bone thickness increases with age, with older individuals having thicker bone, particularly in posterior regions. Diploic layer thickness decreases and may disappear with age, offering data for parietal bone grafts.
Area of Science:
- Anatomy
- Orthopedics
- Gerontology
Context:
- Parietal bone anatomy is crucial for neurosurgery and bone grafting procedures.
- Understanding age-related changes in bone thickness is essential for clinical applications.
Purpose:
- To investigate the anatomical characteristics of the parietal bone in adult Chinese cadavers.
- To determine the relationship between parietal bone thickness, age, and anatomical location.
Summary:
- Average parietal bone thickness was 5.059 mm, increasing with age, especially in the senile group.
- Bone thickness varied significantly across regions, being thicker posteriorly and centrally than anteriorly.
- The diploic layer's thickness diminished with age, sometimes absent in older subjects.
Impact:
- Provides essential anatomical data for optimizing parietal bone harvesting techniques in clinical settings.
- Contributes to a better understanding of age-related skeletal changes in the cranial vault.
