Abstract:
Objective:To evaluate the therapeutic effect of exposed bone cement in treatment of infectious bone and soft tissue defect by comparison with routine bone cement therapy.Methods:A retrospective analysis was carried out in 27 patients who had been treated from January 2016 to January 2020. Of the 27 patients, 12 were treated by exposed bone cement filling for bone defect at the first stage, followed by flap and bone grafting at the second stage. Other 15 patients were treated by routine bone cement filling and flap repair at the first stage, followed by bone grafting at the second stage. Regular dressing change was carried out after surgery. All patients entered follow-up by out-patient review for wound condition and X-ray. Infection rate of bone and soft tissue, time of bone union, flap survive rate and complication were compared between the 2 groups.Results:The follow-up lased for 9-24(16.5±3.9 ) months. The bone defects were all healed. The treatment time of bone defects in the group of exposed bone cement was 25-34(28.5±2.8) weeks. The treatment time of bone defect in the routine cement group was 25-36(29.6±3.4 )weeks. There was no statistical difference between the 2 groups( P<0.05). Two cases in each group had failed in infection control after bone cement implantation. With further debridement, cleaning and other treatment, the infection was under control. All flaps in the 2 groups survived. In the group of exposed bone cement, there were 3 flaps splitting, 2 hemorrhage(effusion) and 1 partial flap necrosis, In the routine bone cement group, there were 4 wound dehiscence, 8 hemorrhage(effusion) and 3 partial flaps necrosis. There was no significant difference in flap complications between the 2 groups( P>0.05). The healing of bone defect was evaluated by Samantha X-ray score, the scores of the 2 groups were 5.41±0.67 and 5.40±0.63, respectively, with no statistical significance. The Paley's approach was used to grade the bone healing and the function of adjacent joints. Paley bone defect healing evaluation results weve all excellent. Joint function assessment were as follow: in the group of exposed bone cement, 6 cases were excellent and 3 were good; in routine bone cement group: 6 cases were in excellent and 5 in good. There was no significant statistical difference. Conclusion:Compared with a routine bone cement treatment, the exposed bone cement in the treatment of infectious bone defects saw a fewer flap splitting and fewer hemorrhage/effusion, without an increase in bone and soft tissue infection. This procedure could be considered for further trials in the treatment of a composite defects of infected bone and soft tissue.
