PENG Block for Total Hip Arthroplasty

Periarticular Nerve Group (PENG) Block for Postoperative Rehabilitation in Total Hip Arthroplasty: a Randomized Controlled Trial

This randomized, double-blinded, placebo-controlled trial seeks to evaluate the efficacy of the pericapsular nerve group block on postoperative rehabilitation.

The pericapsular nerve group, or PENG block, has been recently described and shows promise in providing analgesia to the hip joint. However, the effect of this block on postoperative rehabilitation is uncertain. This study compares a preoperative PENG block to a placebo before total hip arthroplasty under spinal anesthesia. The primary outcome measure is verticalization, walking distance, ability to go out of bed, active lifting of the limb, range of motion in the hip joint, bending range of motion, and abduction range of motion. The secondary measure is postoperative pain assessment during rehabilitation.

Inclusion Criteria:

• Patients > 18 years old undergoing unilateral total hip arthroplasty

Exclusion Criteria:

• refusal to participate
• < 18 yo
• Chronic opioid use
• localized infection
