Abstract:
BACKGROUND:Posttraumatic osteomyelitis is bone infection after surgery of open fractures or other joint, which leads to more secretions in antrum or bone exposed wounds, long treatment cycle, delayed healing of fracture, even disunion. The key link in the treatment is complete debridement, adequate drainage, and the use of external fixators with low interference and far away from lesions. ＜br> OBJECTIVE:To observe the clinical efficacy of external fixator combined vacuum sealing drainage (VSD) in the treatment of post-traumatic osteomyelitis, and compared with conventional catheter drainage. ＜br> METHODS:Since June 2010 to June 2013, 21 patients of post-traumatic chronic osteomyelitis were included in this study and divided into VSD group (n=11) and conventional catheter drainage group (n=10). Al patients in VSD groups underwent debridement and VSD was used to fil dead space, then the wounds were sutured. Cases appeared nonhealing fractures underwent external fixation, 10 cases using external fixators and 1 case retained original external fixator. Al patients achieved the closed wounds at the second phase, 9 cases were directly sutured, and 2 cases received skin flap transplantation. Among them, 1 case received autologous bone graft at the third phase because of bone defects. In the conventional catheter drainage group, al patients underwent debridement and conventional catheter drainage to rinse the wounds after surgery, 3 cases failing to close the wounds changed to receive ordinary dressing and skin flap transplantation at the second phase. Cases appeared nonhealing fractures underwent external fixation. Local swel ing, pain and fever were observed after treatment. The time of total hospitalization stay and fracture healing was recorded. ＜br> RESULTS AND CONCLUSION:The VSD group quickly control ed preoperative symptoms such as swel ing and pain and fever than the conventional catheter group (P＜0.05). The length of hospital stay showed no significant difference between the two groups (P>0.05). Al patients were obtained through clinic service and fol owed up for 24-36 months. The healing time in the VSD group was shorter than that in conventional catheter group (P＜0.05). Until the end of fol ow-up, no patients in the VSD group appeared infection recurrence, and two cases in the conventional catheter group had recurrent infection. The results suggest that VSD combined with external fixator can repair post-traumatic chronic osteomyelitis due to rapid control of infection, easy care, shortened treatment time, and reduced rate of postoperative recurrence. In addition, external fixator can be used as the final fixation for post-traumatic chronic osteomyelitis.
