Bone transport combined with negative pressure closed drainage in therapy of 14 patients with tibia bone infection complicated with bone defect

Objective To investigate the effect of bone transport combined with negative pressure closed drainage on tibia bone infection complicated with bone defect.Methods From January 2009 to February 2012,14 patients with open comminuted tibial infection complicted with bone defects were chose,the length of bone defect was 3-9 cm,with an average of 6.1 cm,and with different degrees of skin and soft tissue defect,bone infection,exposure.Thoroughly debridement of the bone defects,repairment of the fracture,keep periosteum osteotomy was made in the lower leg metaphysis or backbone,and bone transport was made by external fixation with self-made Ilizarov ring,VSD material covering the wound,continuous negative pressure drainage,bone and soft tissue infection and defect was treated at the same time.Results All patients were followed up for 8-12 months after operation,the infection was controlled,the wound was well covered with skin and soft tissue,the extend area and bone defects had bone healing,and the body length was restored.Conclusions Bone transport combined with negative pressure closed drainage has good effect on tibia bone infection combined with bone defect,the treatment of bone and soft tissue defects was achieved at the same time,the combined treatment is the best choice of treatment.
