Overview

Experimental analysis shows that femoral offset significantly influences load to failure in implants, indicating potential fracture risks.

Key Points

  • Higher femoral stem offset reduces load to failure, increasing the risk of fractures.
  • Implants with a 132° neck angle showed an average load to failure of 3,538 N compared to 2,948 N for a 127° neck angle.
  • Biaxial testing was applied to 20 osteoporotic femur models to assess mechanical viability under load.
  • Findings suggest a need for caution in using high offset stems despite benefits in hip stability.
