Key result
A continuous femoral nerve block was equivalent to a posterior lumbar plexus block for postoperative pain after hip arthroplasty (mean difference 0.1; 95% CI -0.9 to 1.2; P=0.78).

Supports continuous femoral nerve block as an acceptable alternative after hip arthroplasty; confirms analgesic equivalence in this RCT.
RCT (n=47)
Does a continuous femoral nerve block provide equivalent analgesia to a continuous posterior lumbar plexus block in patients undergoing hip arthroplasty?
Mean Difference: 0.1 (95% CI -0.9–1.2)
Absolute Event Rate: 3.6% vs 3.5%
p-value: p=0.78
Continuous femoral nerve block is an acceptable, equivalent analgesic alternative to posterior lumbar plexus block after hip arthroplasty, though it may reduce early ambulatory distance.
Ilfeld et al. (2011) conducted an RCT in Hip arthroplasty (n=47). Continuous femoral nerve block vs. Continuous posterior lumbar plexus block was evaluated on Average daily pain scores (0-10) in the 24-hour period beginning at 07:30 the morning after surgery (MD 0.1, 95% CI -0.9 to 1.2, p=0.78). A continuous femoral nerve block was equivalent to a posterior lumbar plexus block for postoperative pain after hip arthroplasty (mean difference 0.1; 95% CI -0.9 to 1.2; P=0.78).
