Methods： All cases were treated in our tertiary level trauma center and teaching hospital including 35 patients with open fractures who were treated by immediate open reduction and plate fixation from January 2008 to August 2010. Among them, 31 patients were available for adequate follow-up and assessment. All fractures were treated by irri- gation and debridement, immediate open reduction and plate fixation along with placement of antibiotic-releasing collagen fleeces around the plate just before closure of wound. Pa- tients were assessed to determine postoperative infection, delayed union or nonunion and development of other post- operative complications. It was hypothesized that immedi- ate plate osteosynthesis after thorough debridement and local antibiotics would give safe and acceptable clinical results in treatment of open fractures. Results： The 31 patients with adequate final follow-up were assessed at a mean time of 40 weeks （15-160 weeks）.Most fractures united primarily in an acceptable time period according to area of involvement. Local wound complica- tions （superficial infection and skin loss） were found in 3 patients （9.67%）. Deep infection was noted in 2 patients （6.45%）. None of these patients needed implant removal and both fractures united in due time. Delayed union was noted in 5 patients （16.13%）. No patient progressed to non- union or implant failure in long term follow-up. Excessive scarring was developed in 2 patients （6.45%）. Conclusions： Immediate plate osteosynthesis after adequate debridement and placement of collagen film eluting antibiotics locally produces excellent results regarding bone union and absence of deep infections and is a safe technique in the management of open bone injuries. These sponges can be used easily with any form of internal fixa- tion and there is no need of second surgery for the removal of these antibiotic carriers since they are bioabsorbable. Local antibiotic-impregnated collagen sponges along with systemic antibiotics for 3 to 5 days offer promising results in open fracture management.展开更多
