For forensic age estimation in individuals above 25 years where epiphyseal fusion is complete, the MOST reliable skeletal indicator is:

• A Pubic symphysis morphology using the Todd or Brooks-Suchey system, reliable up to 50 years ✓
• B Fusion of the sternal end of the clavicle (medial epiphysis), which is the last epiphysis to fuse, typically between 22–30 years
• C Skull suture closure, which provides age estimation accurate to ±2 years
• D Sacro-iliac joint changes, useful only above 60 years

Explanation

Once all epiphyses have fused (by approximately 25 years), pubic symphysis morphology using the Brooks-Suchey system (six phases based on surface texture, margin formation, and ventral rampart) provides the most reliable skeletal age estimation up to approximately 50 years, with phase-specific age ranges and standard deviations. Sternal clavicular fusion is useful for the 17–30 year range specifically. Skull suture closure is notoriously inaccurate (±10+ years). The sacro-iliac joint is supplementary and less standardised.
