Abstract |
Objective |
Because of disabling sequelae of open fasciotomy in anterior compartment syndrome (ACS) of the leg, we wanted to describe and validate a cadaveric model of ACS. We hypothesized that, first, anterior compartment syndrome (ACS) could be reproduced in cadaveric leg and, second, fasciotomy without complete skin incision could lower the intramuscular pressure (IMP) in an equivalent range to complete dermatofasciotomy.
Materials and methods |
Lower limb ACS was reproduced by progressive injection of physiologic serum in the anterior compartment of 23 fresh frozen cadaveric legs with monitoring of IMP, in order to reach a maximal stabilised IMP higher than 30mmHg. Subcutaneous minimally invasive fasciotomy was performed on 14 legs through 5 transversal mini-incisions of the skin (2cm) along the axis from the tibial tuberosity to the posterior aspect of the lateral malleolus. Standard open fasciotomy of the anterior compartment was performed on the remaining 9 legs as control. IMP was measured after the skin incisions and after every fasciotomy through skin incisions in the first group and after skin and fascia incisions in the control group.
Results |
A maximal IMP of 43±2mmHg was obtained by injection of 177±9ml physiologic serum into the anterior compartment of the leg. In the control open fasciotomy group, the skin incision alone did not lower IMP significantly, whereas fasciotomy lowered IMP to 10±1mmHg, which is statistically different from maximal IMP (p<0.001). In the subcutaneous fasciotomy group, complete fasciotomy lowered significantly the IMP to 11±4mmHg (p<0.001), without statistical difference with the control group.
Discussion |
This cadaveric model is effective to reproduce the hyperpressure encountered in ACS. In this model, IMP release after fasciotomy is as efficient through minimally invasive subcutaneous incision as with control open fasciotomy. This in vitro technique appears as an attractive alternative treatment in anterior compartment syndrome of the leg. It should be tested in the other compartments of the leg and its in vivo feasibility in acute conditions has to be clarified.
Level of evidence |
III, control laboratory study.
