Compartment pressures after submuscular fixation of proximal tibia fractures

Tibial fractures are known to be associated with elevated compartment pressures, which may potentially result in a compartment syndrome. The Tibial Less Invasive Stabilization System (LISS PLT) is an internal fixator device that is designed for fixation of proximal tibia fractures. The technique includes submuscular placement of the implant along the lateral border of the tibia. Such placement of the Tibia LISS into the anterior leg compartment could increase compartment pressures, and therefore increase the risk of compartment syndrome. The objective of this prospective study is to determine whether submuscular placement of a tibia LISS fixator increases compartment pressures and what is the incidence of compartment syndrome.
