Ropivacaine strength and effect in ankle block for foot surgery
Treatments studied
Part of Bones, joints & muscles clinical trials.
This study tests different strengths of a numbing medicine (ropivacaine) used in an ankle block for foot surgery. The goal is to find the best dose that starts working quickly and lasts the right amount of time for pain relief after bunion repair.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 75 years old and scheduled for bunion (hallux valgus) surgery on one foot.
- You are in good general health (ASA class I, II, or III — meaning no serious illness or well-controlled illness).
- You can walk on your own (with or without a cane or walker).
- You are willing and able to do simple sensation tests (like feeling a pinprick or cold) at home after surgery.
- You are not allergic to numbing medicines (like ropivacaine) or to common pain relievers like NSAIDs, paracetamol, or tramadol.
- You have not taken strong painkillers (opioids) or gabapentin in the last 3 days, and you weigh at least 50 kg.

This study tests a new nerve-blocking medication (ALX006) injected near the sciatic nerve to reduce pain after bunion surgery. The goal is to see if it provides better pain relief compared to standard care.
This study tests which numbing medicine works faster for an ultrasound-guided ankle nerve block during foot surgery: mepivacaine or bupivacaine. It may help improve comfort by reducing how long it takes for the numbness to start.
This trial compares two methods of pain management after ankle surgery: a one-time injection of long-lasting numbing medicine (liposomal bupivacaine) versus a continuous nerve block via a small tube (catheter) placed near the nerve. The goal is to find which approach provides better pain relief with fewer side effects.
This study tests two different local anesthetics mixed together for a nerve block to numb the lower leg during surgery. It aims to improve pain relief after surgery for patients having below-knee procedures.
This study looks at how well a numbing injection around the ankle controls pain after surgery, and whether it works differently for people with diabetes compared to those without. If you're having foot or ankle surgery and are willing to provide your medical data, this could help improve pain management for patients like you.
This trial tests whether a specific nerve block can reduce pain after a hip socket surgery. The results could help improve recovery and reduce the need for strong painkillers.
