Introduction: The hip fractures appear to be a real epidemic problem, especially in the western world, due primarily to higher average age. The social and economical impact is considerable with a continue social and health costs up-rising. The female-male ratio is approximately 8:1.
Purpose: The purpose of this report is to present a system of osteosynthesis for fractures of the lateral femoral neck. This system is a plate developed by INTRAUMA O'nil(®), 3-hole plate with an 130° angle of valgus and 7° of anteversion.
Materials and methods: At the I Orthopedic Department at the University of Pisa from January 2009 to February 2012 were treated 52 fractures of the femur neck side with this system. All patients undergone to a clinical and X-ray evaluation according to the AO classification: 14 31-A1, 7 31-A2, 4 31-A3.
Results: The mean follow-up was 10 months, in all cases we did not have cut-outs with a TAD average of 23 mm.
Conclusions: This system offers the possibility to perform surgery quickly with low risk of cut-out thanks to 7° of anteversion. Ensures optimal fixation to the femoral shaft and an equitable distribution of forces, eliminating the risk of breakage of the implant and loosening of the screws.
