Multicenter Study Clinical Trial
Minimally invasive fracture stabilization of distal femoral fractures with the LISS: a prospective multicenter study. Results of a clinical study with special emphasis on difficult cases.
The LISS-DF (Less invasive stabilization system-distal femur) is a new type of implant system for the treatment of distal femoral fractures according to the principles of "Minimally Invasive Surgery". A plate, pre-contoured to the anatomy, is inserted through a minimally invasive incision into the epiperiosteal space by means of an aiming device after indirect, closed fracture reduction. The implant is stabilized by insertion of screws which lock into the plate holes and prevent tilting. ⋯ The complications can be attributed in nearly all cases to the severity of the trauma and/or a lack of experience when applying the new style implant to a wider range of indications. The results of the study show that with a sound knowledge of the operative technique and careful preoperative planning this system represents an excellent, safe procedure for the treatment of almost all distal femoral fracture types including periprosthetic fractures of the distal femur. There is generally no need for primary cancellous bone grafting.

A multicentre retrospective analysis of blunt gastric injuries from four trauma centres in Brazil was performed. From January 1982 to May 1996, 33 patients were found to have blunt gastric injury: 26 were male and the mean age was 26.2 years. The most frequent mechanism of injury was automobile versus pedestrian (17) followed by motor vehicle accidents (seven). ⋯ Overall morbidity and mortality was 12 (36%) and nine (27%), respectively. The ISS was higher in the non-survivor group (P=0.03) and the gastric organ injury score did not reach statistical significance when comparing survivors and non-survivors. We conclude that blunt gastric injury is uncommon and is associated with other injuries of greater magnitude, which generally influence mortality.
