This randomized controlled trial evaluated the relationship between preoperative femoral bone texture on radiographs and early femoral stem subsidence in 63 participants undergoing total hip arthroplasty. The study found that hips with greater than two mm of early subsidence exhibited significantly lower texture energy and mean intensity, indicating poorer bone quality.
Key findings
- Hips with greater than two mm subsidence had lower texture energy (P = 0.0003 to 0.014).
- Mean intensity was also lower in hips with greater than two mm subsidence (P = 0.0005 to 0.026).
- Texture parameters increased over time in both subsidence groups (P < 0.0001).
Why it matters
Understanding the association between bone texture and stem subsidence can aid surgeons in selecting appropriate implant designs, potentially improving patient outcomes by minimizing the risk of subsidence.
