Reducing Malalignment Rates in Distal Tibia Fractures

Study finds suprapatellar approach to IMN insertion superior to infrapatellar approach

  A study comparing two intramedullary nail (IMN) insertion techniques in the treatment of distal tibia fractures found that the suprapatellar approach yielded a significantly lower rate of malalignment (3.8 percent) than the infrapatellar approach (26.1 percent). Although use of a locked IMN in an infrapatellar technique "has been shown to enable a successful outcome," according to the authors, "obtaining correct alignment has historically been problematic." This is due to the difficulty in properly placing the IMN in the broadened region of the distal tibia.
