Conclusions
postoperative pain
In summary, our study found no significant superiority of IPB over FNB in terms of postoperative analgesia following hip arthroplasty. However, IPB demonstrated notable advantages in terms of motor sparing, which may facilitate earlier recovery and rehabilitation for patients. Given these findings, IPB could be considered a viable alternative to FNB in the management of postoperative pain following hip arthroplasty. Further research is needed to optimize the application of IPB in clinical practice and explore its potential benefits in different patient populations.
