摘要：

The effect of construct length on cortical strain and load to failure between locked compression plating and cemented femoral stem in a fall model was analyzed. Eight Sawbone femurs with cemented stems were instrumented with increasing fixation lengths starting El cm distal to stem tip and progressing proximally to overlapping constructs. Uniaxial strain gauges measured cortical strain. Load to failure was performed with 8 cm gap between implants, 2 cm gap, and proximally overlapping configurations. Strain was significantly reduced as the 8 cm gap transitioned to an overlapped construct with most comparisons. Load to failure in the overlapped construct was 273% greater compared to 2 cm gap construct. Overlapping the stem with a locking compression plate resulted in reduced strain and increased load to failure. (C) 2014 Elsevier Inc. All rights reserved.
