Pericapsular Nerve Group (PENG) Block Versus Supra-inguinal Fascia Iliaca Compartment Block for Pain Management After Total Hip Arthroplasty: a Randomized Controlled Trial

Pericapsular Nerve Group (PENG) Block Versus Supra-inguinal Fascia Iliaca Compartment Block for Pain Management After Total Hip Arthroplasty: a Randomized Controlled Trial

Adequate pain control after total hip arthroplasty is crucial for early ambulation and patient satisfaction. The supra-inguinal fascia iliaca compartment block has been described as a promising technique for primary total hip arthroplasty. However, one of the concerns with supra-inguinal fascia iliaca compartment block is still the potential for quadriceps weakness that might delay ambulation. The pericapsular nerve group (PENG) block has been recently introduced a new technique for blockade of the articular branches of the femoral, obturator and accessory obturator nerves. PENG block is possible to provide sufficient analgesia and preserve lower limb muscle strength. The investigators will compare ultrasound-guided supra-inguinal fascia iliaca compartment block with PENG block in patients undergoing total hip arthroplasty.
