Meindl-Lovejoy Vault System
Definition
A five-site composite scoring system for ectocranial suture closure at midlambdoid, lambda, obelion, anterior sagittal, and bregma sites, derived from the Hamann-Todd Collection; one of two Meindl-Lovejoy composite systems.
- Sites scored
- Midlambdoid, lambda, obelion, anterior sagittal, bregma
- Basis
- Hamann-Todd Collection
- Use
- Adult age estimation from cranial suture closure
- Type
- Composite ectocranial scoring system
Common questions
Why does the vault system use five sites instead of a single suture?+
Individual sutures close at highly variable rates and are unreliable predictors on their own, so combining scores across five vault sites reduces the error introduced by any one site closing unusually early or late in a given individual.
How reliable is the vault system compared to other adult ageing methods like pubic symphysis or rib-end scoring?+
Cranial suture closure is generally considered less precise than pubic symphysis or sternal rib-end methods for younger and middle-aged adults, so practitioners typically use it as a supporting method alongside other indicators rather than the primary age estimator when better-preserved skeletal elements are available.
