ClinConnect Summary

This clinical trial is studying a new technique called the femoral articular branch block (FAB) to help reduce pain after hip replacement surgery, also known as hip arthroplasty. The goal is to see if this method can lower the need for strong pain medications (opioids) and improve how well patients recover after surgery. In this trial, half of the participants will receive the FAB block, while the other half will receive a placebo, which is a treatment that looks the same but has no active ingredients. By comparing both groups, researchers hope to determine how effective the FAB block is in managing pain.

To participate in this study, you need to be between 18 and 60 years old, have a body mass index (BMI) of 35 or less, and be generally healthy (ASA I-III). However, if you have certain medical conditions, such as nerve damage in the relevant areas, infections, or allergies to local anesthetics, you might not be eligible. Participants can expect to be randomly assigned to either the FAB block or the placebo group, and they will be monitored for pain levels and recovery experiences after their surgery. It's important to note that the trial is not yet recruiting participants, but it aims to gather valuable information that could help improve pain management for future hip surgery patients.
