Böcker et al. 2026 state the trabecular>cortical turnover premise as a single unqualified sentence, citing Parfitt 2002 (ref 21) with no site, age, or method caveat

Lerebours et al. 2020, independent of both Böcker and Parfitt, cite Parfitt 2002 in both directions — as authority for the standard ~4x cortical/trabecular turnover gap and as caution against generalizing it

Does Parfitt 2002 (Böcker's ref 21) actually support 'trabecular bone turns over faster than cortical bone,' or does its title-flagged 'misconception' complicate the premise beneath the whole spaceflight/bed-rest compartment cluster?

capture promoted 2026-08-23 · space-medicine, aerospace-physiology, bone-density, trabecular-cortical, bone-turnover
Böcker's cited compartment literature (refs 12, 22, 23) does support a genuine bed-rest-cortical / spaceflight-trabecular dissociation, not simply 'trabecular bone loses faster everywhere'

Rittweger et al. 2010, read in full, finds 56 days of strict bed rest produced tibial epiphyseal bone loss that was almost exclusively cortical, with virtually no trabecular loss

Sibonga et al. 2019 reports that in-flight resistive exercise (ARED) prevented cortical vBMD decline at the femoral neck but did not prevent hip trabecular vBMD loss

Vico et al. 2017 reports that after ISS missions, tibial cortical bone structure recovered within a year of landing while cortical porosity and trabecular bone did not

Does the compartment-level literature (Böcker's refs 12, 22, 23) support that spaceflight loses more trabecular bone while bed rest loses more cortical bone?

Converted to a monthly rate, Böcker's spaceflight tibial bone loss approaches Stavnichuk's −0.8%/month only at the trabecular-rich epiphyseal sites and falls an order of magnitude short at the cortical diaphyseal sites

Does the compartment-level literature (Böcker's refs 12, 22, 23) support that spaceflight loses more trabecular bone while bed rest loses more cortical bone?
