Summary
Adequate pain management following total hip arthroplasty (THA) is a key component for
patient satisfaction and early ambulation. However, due to the complexity of the innervation
of the hip joint, the most appropriate anaesthetic and analgesic technique for THA remains
unclear. A femoral nerve block is commonly performed and well established but is associated
with motor weakness. Recently, the pericapsular nerve group (PENG) block has been introduced
as an effective choice which targets the articular branches of the hip. The quadratus
lumborum block (QLB) is a relatively new regional block that has been reported to provide
effective analgesia for THA.
The main objective of this study is to compare the effectiveness of the ultrasound-guided
PENG block technique compared to QLB block in terms of efficacy of pain control and the
safety profile after total hip arthroplasty under spinal anesthesia.
