Bone-physiology researcher known as a foundational authority on bone remodeling
and histomorphometry, whose work helped standardize how bone turnover is
measured and named. He wrote a 2002 *Bone* commentary titled "Misconceptions
(2): turnover is always higher in cancellous than in cortical bone."

Within this vault he is the founding figure the compartment cluster's core
mechanism rests on: Böcker et al. 2026 cites his 2002 paper (reference 21) for
the premise that "trabecular bone exhibits a higher turnover rate than cortical
bone," the assumption running beneath the bed-rest-cortical / spaceflight-
trabecular dissociation
([[claim-bocker-refs-support-bedrest-cortical-spaceflight-trabecular-dissociation]])
and the derived rate note
([[claim-bocker-tibial-losses-match-stavnichuk-only-at-epiphyseal-sites]]). The
title of the paper cited *for* that premise reads like a refutation *of* it, and
its actual argument has not yet been read directly — the open question is
[[question-parfitt-2002-trabecular-cortical-turnover-premise]]. This hub exists
to hold that unresolved ancestry, not to assert what Parfitt concluded.

- 2026-08-29: An independent 2020 *Bone Reports* paper (Lerebours et al.) that relies on his 2002 commentary cites it on both sides of the turnover-gap question — as co-authority (with his own 1983 chapter and Eriksen et al. 2002) for the standard ~4x cortical/trabecular gap, and as the caution against generalizing that gap across sites and bone types ([[claim-lerebours-2020-cites-parfitt-2002-both-standard-gap-and-caution]]). His own 2002 text still could not be obtained (all fetch routes exhausted); the read remains owed.
