Project description:A study of rat femoral fracture healing in young (6 weeks old at fracture), adult (26 weeks old at fracture), and old (52 weeks old at fracture) rats. Samples were collected at time of surgery (intact controls) and at 3 days, 1 week, 2 weeks, 4 weeks, and 6 weeks after fracture. Samples were the mid third of the femoral length including the external callus, cortical bone and marrow elements. Fracture was stabilized with an intramedullary rod prior to fracture with a Bonnarens and Einhorn device.
Project description:This is a study of femoral fracture healing in female rats 16 weeks old at fracture to compare intramedullary nailing, screw and plate fixation, and sham surgery. The sham surgery group received a surgical exposure of the femur, but no fracture, no plate, and no nail. Samples were collected at 1 day, 3 days, 1 week, 2 weeks, 4 weeks, and 6 weeks after surgery. Each sample is a pool of RNA from three rats from the same surgery group at the same time point after fracture. The middle third of the femur was collected with the cortical bone, fracture callus, and marrow elements. Mid-diaphyseal, simple, transverse fractures were induced by a Gigli saw. The no fracture sample was a time 0 control collected on the day of surgery from intact rats.
Project description:The association between DM and impaired fracture healing including delayed union and nonunion has been documented in clinical and experimental settings. We examine mRNA expression specific for impaired fracture healing in diabetic rat.
