LISS Proximal Lateral Tibia: Study Results

The LIS system for the proximal tibia is an anatomically pre-contoured implant for the treatment of fractures of the proximal tibia. In the course of a prospective clinical study, 135 patients with 138 fractures were treated with the new system at 13 European trauma centers from June 1998 to March 2000 and the cases were documented. The follow-up period was at least 12 months and ended in June 2001. Principle clinical investigator is C. Krettek, Hanover. AOCID monitored the study.

The inclusion criteria took in fractures of all degrees of severity of the proximal tibia and the tibial shaft. The fractures were classified as 110 fractures of the proximal tibia (AO 41) and 28 tibial shaft fractures (AO 42) according to the AO fracture classification system; type C fractures accounted for a total of 66% (n=91). A follow-up rate of 94% was achieved with reference to the number of fractures treated. The results of the study were evaluated immediately in close collaboration with the Principal Clinical Investigator. It is expected that the evaluation will be completed by the end of 2001; the results will be summarized and published in a final report.
