title: Computer assisted LISS plate placement: an in vitro study.
abstract: A laboratory study was conducted to compare the accuracy with which a LISS plate could be placed on the distal metaphysis of a model femur using both a fluoroscopy-based computer assisted technique and the conventional fluoroscopic technique. A significant difference was found between outcomes with the two approaches with respect to the maximum distance from the plate to the diaphysis of the bone, but there was no significant difference in the maximum distance to the condylar area. There was also no difference with respect to the number of holes that required re-drilling for adjustment of the plate placement or screws with poor purchase in bone. There were, however, significant differences between the two techniques in terms of duration of the procedure and radiation exposure.
