BackgroundIntracompartmental pressure (ICP) monitoring is a widely used modality, particularly after intramedullary nailing of tibial shaft fractures. It was hypothesized that ICP value in fracture fixed with Ilizarov circular fixator (ICF) might be lower than in fracture fixed with intramedullary pin (IMP). The present study is a comparison of ICP value in tibial fractures in a rabbit model fixed with ICF and IMP.MethodsTwenty male New Zealand White rabbits were randomly divided into 2 groups of equal size: ICF group (Group 1) and IMP group (Group 2). Under anesthesia, half of proximal part of the right tibia of all rabbits was fractured. Tibial fractures were fixed with ICF in Group 1 and IMP in Group 2. ICP values were monitored at 6-hour intervals for 48 hours.ResultsThere was statistically significant difference in ICP value between groups (p<0.001). While there was statistically significant increase in ICP values 24 hours post surgery, there was statistically significant decrease during second 24 hours following surgery. Most importantly, ICP values of ICF group were significantly lower than those of IMP group at 30, 36, and 42 hours post surgery (p<0.05).ConclusionAt 24th hour after fixation, ICP values measured in ICF group were lower compared with those of IMP group. These results indicate that use of ICF in tibial fractures provides additional decompression in the anterior compartment. In light of these findings, ICF may be preferable for treatment of tibial fractures with high risk for compartment syndrome.
