A Thesis submitted to The University of Arizona College of Medicine - Phoenix in partial fulfillment of the requirements for the Degree of Doctor of Medicine. / The (Surgical Implant Generation Network) SIGN Intramedullary (IM) nail is designed to fix long bone fractures without using a costly C‐arm imaging device. It is distributed for free to countries in need, allowing for elevation of care from the standard, lengthy traction treatment in those countries to clinically superior IM nailing. This paper compares the clinical outcomes of the SIGN IM nail to those of the IM nails used in developed countries with use of a C‐arm. The terms “Surgical Implant Generation Network” and “union” were searched in four databases. Primary studies of SIGN IM nails were included and their outcomes, including union rate, time to union, and complications, were recorded and compared to historical data of IM nails used in developed countries. Overall, there is a similar union rate in bones fixed with SIGN IM nails (94.6%) versus bones fixed with IM nails in developed countries (92.3%) (p = 0.009, OR = 1.67), while some bone types (tibia and femur) demonstrated a lower union rate when individually stratified (p = 0.008, OR = 0.26 and p = 0.002 and OR = 0.15, respectively). Mean time to union for all bone types combined showed no significant difference between SIGN IM nails and IM nails used in developed countries (p = 0.26). Complications rates were similar between SIGN IM nails and IM nails used in developed countries. It is possible for the SIGN IM nail to be used to fix long bone fractures in developing countries with outcomes comparable to the IM nail used in developed countries.
