From: Topical cutaneous application of CO2 accelerates bone healing in a rat femoral defect model

Parameter Control CO2
TMD (mg/cm3) 605.6 ± 55.5 635.8 ± 55.2
TV (cm3) 0.062 ± 0.0097 0.063 ± 0.014
BMC (mg) 11.2 ± 2.83 15.7 ± 4.68
vBMD (mg/cm3) 180.9 ± 43.0 247.9 ± 49.9*
  1. The vBMD of the callus was significantly greater in the CO2 group than in the control group. * p < 0.05 compared to the control group. TMD tissue mineral density, TV total callus volume; BMC bone mineral content; vBMD volumetric bone mineral density (BMC/TV)
