Abstract
Nowadays, DC electric stimulation is used as an alternate diagnostic tool to predict fracture healing; by orthopedic surgeons to minimize the number of radiographs. A DC voltage of 0.7V was applied across tibia fracture site stabilized with Teflon coated carbon rings and the data was recorded at various patient follow-up periods. A regular pattern of conduction characteristics was observed across the tibia fracture site, in this work we classify the fracture into 3 broad categories namely stable, unstable and irregular based on the fracture pattern. The electrical data was recorded across 20 different tibia fracture patients whose fracture type were Grade III Open fracture, Grade I open comminuted fracture, displaced fracture, oblique, transverse, irregular and irregular fracture with gap non unions needing corticotomy. The variation of current for the range of applied input voltage 0.7V was calibrated. The data exhibited common conductance characteristics across patients who had similar type of fracture, clinical manifestation fall history of the injury and reporting time irrespective of variation in bodily status of the individual. From the results the fracture type such as transverse grade III open fracture, were classified into broad category namely stable fractures.;fracture types such as oblique, wedge and Comminuted were classified as unstable; while corticotomy, displaced were classified as irregular. A unique pattern of variation of current in initial period its steep fall at the time of healing and later becoming constant was observed in all cases irrespective of fracture types. Individual fracture types fitting into broad category of fracture classification is also inferred in this work. Various parameters like process gain, time constant are calculated.
