Objective:To evaluate the curative effect of hyperbaric oxygen assisting minimally invasive plate osteosynthesis in treating the middle and distal tibia fracture and its influence on the blood supply.Methods:One hundred cases of patients with tibial fractures from January 2016 to December 2018 admitted to the First Department of Ortho Pedics Forth People′s Hospital of Shenyang were selected and randomly divided into control group ( n=50) and observation group ( n=50). The control group was treated with minimally invasive steel plate osteoplasty, and the observation group was treated with hyperbaric oxygen therapy on the basis of the treatment of the control group for 4 consecutive weeks. The pain intensity scores measured by Visual Analog Scale (VAS), skin blood supply at the fracture site, fracture healing and scabbing, bone density, knee/ankle function were compared between the two groups 1 week, 1 month, and 6 months after surgery. Results:One week after surgery, the differences of VAS, fracture healing scores, and bone density between the groups all showed no statistical significance ( P>0.05). One month after surgery, the VAS score, the score of fracture healing and scabbing, and the bone density of the observation group were significantly better than those of the control group ( P<0.05). In the observation group, the incidence of poor blood supply to the skin at the fracture site was 14.0%, which was significantly lower than that of the control group (32.0%) ( P<0.05). The recovery rate of the function of knee and ankle joints was 58.0%, which was higher than that in the control group (38.0%) ( P<0.05). Six months after surgery, the VAS score of the observation group was significantly decreased, and the bone density in the observation group was significantly increased, compared with those of the control group. All differences were statistically significant ( P<0.05). The blood supply to the skin, the fracture healing and scabbing, and the functional recovery of knee and ankle joints of the observation groups were better than those of the control group, but there were no statistical differences( P>0.05). Conclusion:Hyperbaric oxygen assisting minimally invasive plate osteosynthesis in treating the middle and distal tibia fracture could increase the partial pressure of blood oxygen, accelerate the revascularization at the fracture site, reduce local tissue edema and necrosis, promote bone healing, and reduce postoperative pain, which could be used as an auxiliary treatment for the middle and distal tibial fracture.
