Nerve Blocks for Lower Extremity Fractures
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether nerve blocks, injections that numb pain, can aid older adults in recovering from lower leg fractures. Nerve blocks have already improved outcomes for hip fractures, but their effectiveness for other leg bones, such as the thigh or shin, remains uncertain. The trial will compare patients receiving these nerve blocks (local anesthesia injections) before surgery to those who do not, assessing whether the blocks lead to fewer complications and faster recovery. Suitable candidates for this trial have a recent leg fracture requiring surgery and can provide informed consent. As a Phase 4 trial, this research aims to understand how an already FDA-approved and effective treatment can benefit more patients.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What is the safety track record for local anesthesia injections?
Research has shown that nerve blocks, which involve injecting medicine to numb a specific area, are generally safe for surgeries. Studies have found that these blocks effectively reduce the need for other pain medications after surgery, easing recovery for patients.
Most patients tolerate nerve blocks well. They help decrease the use of opioids, strong painkillers with potential side effects. Although rare, risks such as nerve injury or infection can occur.
In summary, despite minor risks, nerve blocks are usually safe and effectively manage pain during and after surgery.12345Why are researchers enthusiastic about this study treatment?
Researchers are excited about using pre-incision peripheral nerve blocks for lower extremity fractures because this method could offer longer-lasting pain relief right from the start of surgery. Unlike standard anesthesia options, which might include general anesthesia or neuraxial blocks, these nerve blocks use long-acting local anesthesia that targets pain specifically in the fracture area. This approach not only aims to enhance pain control during and after surgery but may also reduce the need for opioids, which can have significant side effects.
What evidence suggests that nerve blocks are effective for lower extremity fractures?
Research has shown that nerve blocks help older adults with hip fractures. Studies have found that these blocks lead to fewer deaths, fewer serious problems, and shorter hospital stays, suggesting they might do more than just relieve pain. Nerve blocks stop pain signals, reducing the need for opioid painkillers. In this trial, participants will receive either pre-incision peripheral nerve blocks or no peripheral nerve block for lower extremity fractures. Although less information exists about their effects on other leg fractures, the positive results for hip fractures strongly support considering their use for other leg breaks.678910

Are You a Good Fit for This Trial?
This trial is for older adults who have suffered fractures in their lower legs, such as hip or other leg bone breaks. Participants must be able to receive local anesthesia injections. Specific inclusion and exclusion criteria are not listed, but typically these would involve age restrictions, the type of fracture, overall health status, and ability to follow the study protocol.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Local anesthesia injections
Trial Overview
The pilot study is testing whether peripheral nerve blocks before surgery can help older adults recover better from lower extremity fractures. It aims to see if this approach leads to fewer complications and shorter hospital stays compared to standard care without nerve blocks.
How Is the Trial Designed?
2
Treatment groups
Active Control
Long-acting local anesthesia for pre-incision peripheral nerve blocks that cover the fracture and surgical pain during definitive surgical fixation of lower extremity fractures.
No peripheral nerve block for definitive surgical fixation of lower extremity fractures. Participants can receive standard anesthesia options for their surgical intervention including neuraxial or general anesthesia, surgical site infiltration, and multimodal analgesia.
