Mechanical simulation experiment of combined locking and non-locking screw fixation for osteoporotic supracondylar femoral fractures
[ 2012-09-19 ]
At present, in the surgical treatment of femoral supracondylar fractures, the clinical application of locking plate fixation technology has been relatively extensive. According to the need for reduction of femoral supracondylar fractures, the placement of non-locking lag screws in the locking screw holes is a frequently used hybrid fixation technique. However, the biomechanical properties of this hybrid fixation method have not yet been reported in related studies. Recently, Dave J. Dalstrom, MD of the Institute of Orthopaedics and Biomedicine of Wright State University in the United States used an osteoporotic femoral supracondylar fracture locking plate fixation model to conduct an experimental study on the mechanical effects of the position and number of the locking screws in the diaphyseal part. , And announced its research results in the latest issue of JOrthopTrauma.
