The utilization of autologous growth factors for the facilitation of fusion in complex neuropathic fractures in the diabetic population.

A review of current knowledge of autologous growth factors as used in foot and ankle surgery is presented. This knowledge is clinically correlated with 50 Charcot's foot reconstruction patients who had diabetes and who were randomized to a platelet-rich plasma (PRP) concentration system (Symphony, DePuy, Warsaw, Indiana) or a hollow-fiber hemoconcentration system (Interpore Cross AGF, Interpore Cross, Irvine, California) trial. Although the literature supports the notion that Symphony produces a higher yield of intact platelets more consistently, clinically, a statistically significantly higher number of patients treated with Interpore Cross AGF went on to solid fusion. The findings may indicate that one type of PRP may be indicated for a particular clinical circumstance based on the patient's medical history and resultant local wound environment.
