Introduction: In revision surgery, modular implant components allow the surgeon to tailor the characteristics of the implant to the bone situation. Relative motion can occur at the tapered modular connection, leading to fretting corrosion and subsequent biological reactions, particularly due to poor assembly and contamination of the tapered connection. The aim of this study was to demonstrate whether incomplete assembly and inadvertent contamination of the modular taper causes a change in junction strength.

- The study investigates whether adding wider and less prominent splines to a revision hip stem can improve its stability and prevent complications that often lead to hip revision surgeries.
- Experimental methods included a comparison of torsional strength between a standard revision stem and a prototype with additional splines, using human femurs to test their effectiveness.
- Results showed that the prototype design had significantly greater cortical contact and torsional strength than the standard model, suggesting that spline modifications could enhance hip implant performance.
