The influence of local infiltration analgesia after total hip replacement. A randomized clinical trial.

To determine whether local infiltration analgesia by catheter infusion was superior to conventional analgesia in terms of postoperative pain control after THR. A randomized double-blind clinical trial was performed. There were four groups based on catheter placement and the infusion constituents : 1) Intraarticular catheter + anesthetics ; 2) Intraarticular catheter +placebo ; 3) Subfascial catheter + anesthetics ; 4) Subfascial catheter + placebo.

Which immobilization is better for distal radius fracture? A prospective randomized trial.

Introduction: The aim of this study was to determine whether an above-elbow cast (AEC) is better than a below-elbow cast (BEC) at maintaining the initial reduction in the orthopaedic management of a distal radius fracture (DRF).

Methods: It is a prospective randomized study carried out in a single emergency trauma department. There were 72 patients older than 55 years of age (55-96) with a distal radius fracture treated orthopaedically.
