Soft tissue complications often dictate the success of limb salvage and the overall outcome of open fractures. Based on prior work at our institution, we hypothesize that wounds greater than 200cm are associated with a greater likelihood of both flap-related reoperation and wound complications among patients requiring soft tissue reconstruction with a rotational flap or free tissue transfer.
We performed a secondary analysis of FLOW trial data that included all patients who received a rotational or free tissue flap transfer for an open fracture. Our primary outcome was flap-related reoperation within 12 months of injury. Our secondary outcome was wound complication, which included events treated operatively or non-operatively. Multivariable logistic regression was used to assess the association between wound size and the outcomes, adjusting for confounders.
17.0% of the 112 patients required a flap-related reoperation. A wound size of greater than 200cm was not associated with reoperation in an unadjusted model (p=0.64) or adjusting for Gustilo type (p=0.70). The sample had an overall wound complication rate of 47.3%. Patients with a wound size of greater than 200 cm were three times more likely to experience wound complications (Odds Ratio: 3.05, 95% CI 1.08- 8.62, p=0.04) when adjusting for moderate-severe wound contamination and wound closure in the operating room.
The findings of this study demonstrate that wound surface area is an integral determinant for wound complication following soft tissue flap treatment, but found no association between wound surface area and flap-related reoperation rates.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 April 2018.
All research outputs
#18,893,608
of 27,394,475 outputs
Outputs from Plastic and Reconstructive Surgery
#8,005
of 10,924 outputs
Outputs of similar age
#227,597
of 345,823 outputs
Outputs of similar age from Plastic and Reconstructive Surgery
#105
of 130 outputs
Altmetric has tracked 27,394,475 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 10,924 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.9. This one is in the 20th percentile – i.e., 20% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 345,823 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 25th percentile – i.e., 25% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 130 others from the same source and published within six weeks on either side of this one. This one is in the 15th percentile – i.e., 15% of its contemporaries scored the same or lower than it.
