Common causes of compartment syndrome include long bone fractures, high-energy trauma, puncture wounds, venous injury, crush injuries. If the pressure continues to rise for several hours, then tissue will die and it may cause irreversible damage. Currently, a needle is inserted into the area of suspected compartment syndrome while an attached pressure monitor records the pressure to diagnose the compartment syndrome. The invasive method has some problems: 1. neurovascular injuries and wound infections. 2. it has to be used in operaration room. This study developed a non-invasive compartment pressure measuring system which is with flexble pressure sensors, and experiments were performed with this system on a lower leg CS simulation model. Compartment pressure and on skin pressure according to placed sensor positions were simulated by finite element analysis software ANSYS Workbench 14.5. In addition, the material properties of nonlinear materials, soft tissue and muscle, were applied in the theoretical simulation to approach the real lower leg compartment syndrome case, to study tissue and muscle deformation and pressure distribution. Finally, the results of the experiment and simulation were discussed in detail.
