HBO effect on the mineral density of bones in the site of fracture

The effect of HBO on the mineral density was studied in 23 patients at the age of 20-50 years; it was studied both in the site of fracture and in the skeletal parts distant from the injury site, the spine, using a roentgen double-energy bone densitometer of «GE/Lunar» firm (USA). HBO was prescribed on 3, 7-15 or 20-25 days after fracture occurrence. It was performed by sessions, 5 or 10 in number. In the control group to which patients with injuries were attributed, who were not subjected to HBO sessions, mineral density gradually decreased. Demineralization accounted for 30% on day 21. If HBO was prescribed from the third day after fracture occurrence and performed by five sessions, the process of demineralization of bone fragments necessary for organic matrix contact was accelerated. If HBO was made by 10 sessions, reparative process was accelerated as well. If HBO was started on 7-15 or 20-25 days after fracture the best effect of osteogenesis stimulation was noted.
