Continuous Psoas Compartment Block for Postoperative Analgesia After Total Hip Arthroplasty: New Landmarks, Technical Guidelines, and Clinical Evaluation

Abstract

Lumbar plexus depth is correlated with the patient's body mass index and differs between men and women, but this is not true of the lumbar plexus-transverse process distance. Considering new landmarks, a continuous psoas compartment block promotes optimal analgesia after hip arthroplasty, with few side effects.
