Purpose

Management of compound fractures, which have a higher infection risk than closed fractures, currently depends on surgeon training and past practice rather than evidence based practice. Some centres use delayed closure involving a second surgery with repeat debridement and wound closure 48 hours after initial debridement and fixation. Other centres use primary closure in the absence of gross contamination or major soft tissue deficits, where debridement, fixation and wound closure occur during the initial surgery. Delayed closure was used at our centre until January 2009 when the standard of care evolved to primary closure where appropriate. Primary closure allows more efficient OR utilization due to fewer OR visits, but it is unknown if primary closure increases the risk of infection, which can, in turn, lead to fracture non-union. The purpose of this pilot study was to complete a safety analysis of infection rates in the first 40 patients undergoing primary closure of a compound fracture; enrolment is ongoing and updated results will be presented.

Method

Patients admitted in 2010 with a long bone(femur, tibia/fibula, humerus, radius/ulna) Gustilo grade I-IIIA compound fracture, without the following: gross organic contamination, compartment or crush syndrome, amputation, or gunshot wound, were eligible for primary closure at fracture fixation, and thus for study inclusion.

The analysis compared primary closure subjects with matched delayed closure subjects taken from a previous prospective cohort study of >700 subjects. Subjects were matched at a one:two ratio(i.e. one primary closure:two delayed closure patients) on fracture location, Gustilo grade of fracture, age(within five years), significant comorbidities(diabetes, kidney disease and osteoporosis) and social factors(smoking and alcohol abuse). The outcomes were 1) any infection and 2) deep infection within six weeks of surgery. Time on antibiotics and length of hospital stay(LOS) was also recorded.
