Introduction: Compartment syndrome is one of the most devastating complications in orthopaedic trauma cases. The aim of this study is to investigate whether the intra-compartmental pressure changes rise and stay above the dangerous limits during percutaneous bridge plating of tibial shaft fractures necessitating fascial release or not.

Patients and Methods: Between January 2007 and April 2009 17 isolated tibial fractures of the 17 patients were treated with percutaneous bridge plating technique by a single orthopaedic trauma surgeon. During the operation before, during and after the plating leg compartmental pressures were measured by using invasive blood pressure monitor. Demographic, trauma and fracture related data were also recorded. Analyses were performed by using SPSS 13.

Findings: Mean age was 32 (19–55) years. Mean of ISS was 14 (10–27). Plating was performed at a mean of 3,3 (1–6) days after the trauma. Means of difference between systolic and diastolic blood pressure and leg anterior compartment pressures just before the plate insertion were 42 and 25,5 (16–32) mmHg respectively. During plating compartmental pressures rose to a mean of 51,5 mmHg (p=0,001) and dropped to 50 mmHg 10 minutes after implantation. Mean delta P was – 7 mmHg for the leg antertior compartment ten minutes after plating. No correlation was found between the blood pressure differences; ISS; age; type of anesthesia and delta P (r< 0,1 and p> 0,05). Although there is a trend of having decreased delta P with earlier surgery difference was not significant (r=0,18; p=0,058).

Conclusion: Anterolateral percutaneous bridge plating of tibial shaft fractures significantly increases intracom-partmental pressures. Physician should carefully judge the risk of compartment syndrome in each patient separately and should not hesitate to perform percutaneous fascial release intraoperatively.
