The xiphoid process usually fuses with the body of sternum around: 40 years of age
This fusion is important in:
-
- Age estimation
- Forensic medicine
- Radiological anatomy
| Joint/Structure | Approximate Fusion Age |
|---|---|
| Xiphoid with sternum | 40 years |
| Sternal angle fusion | Later adulthood |
| Medial clavicular epiphysis | 25 years |
| Sacral vertebrae fusion complete | 25–30 years |
- Xiphisternal joint:
- Initially cartilaginous
- Later ossifies and fuses with body of sternum around 40 years.
