CLINICAL EFFECT OF CANCELLOUS BONE TRANSPLANTATION COMBINED WITH CLOSED SKIN GRAFTING FOR POST-TRAUMATIC OSTEOMYELITIS
Objective To investigate the clinical effect of cancellous bone transplantation combined with closed skin grafting in the treatment of posttraumatic osteomyelitis.Methods Totally 40 cases of post-traumatic osteomyelitis in our hospital from January 2014 to January 2016 were randomly divided into treatment group (n =20) and control group (n =20) with a random number table.The patients in the treatment group were treated by cancellous bone transplantation combined with closed skin grafting,and the control group by traditional open bone grafting surgery.The clinical outcome was compared between the two groups.Results Before debridement,the area of soft tissue defect showed no significant difference between the two groups (P>0.05).At postoperative 1 and 2 months,the area of soft tissue defect was significantly decreased in both groups,and it was significantly smaller in the treatment group than in the control group (t =3.28 and 2.08,P<0.05).The wound healing time and bone healing time in the treatment group were significantly shorter than those in the control group (t=11.32 and 9.30,P<0.05).No recurrence was observed in the treatment group,while 4 patients had recurrence in the control group,indicating a significant difference (x2 =4.44,P<0.05).The percentage of patients with excellent healing was 95% in the treatment group and 60% in the control group,suggesting a significant difference (x 2 =7.03,P < 0.05).Conclusion Cancellous bone transplantation combined with closed skin grafting for traumatic osteomyelitis has the advantages of short wound healing time,quick bone healing,low infection rate,low recurrence rate,and high efficiency and safety,and it holds promise for clinical application.
