Brief Summary

Comparison of Anesthetic and Postoperative Analgesic Efficacy of Femoral and Popliteal Sciatic Block vs Femoral and Anterior Sciatic Block in Ankle Surgery

Detailed Description

The sciatic nerve, which arises from the sacral plexus, is the largest nerve in the body. It originates in the posterior region of the thigh in the lumbosacral area and is formed from the anterior branches of spinal nerves from L4 to S3 within the pelvis. It exits the pelvis through the greater sciatic foramen directly below the piriformis and then progresses towards the posterior compartment of the thigh, where it usually divides into the common peroneal nerve and the tibial nerve at the upper corner of the popliteal fossa. Sciatic nerve blocks provide both analgesia and anesthesia in surgeries below the knee, knee surgeries involving the posterior compartment, and foot and ankle surgeries. They can be used alone or in combination with an ipsilateral lumbar plexus block or femoral nerve block to provide surgical anesthesia or analgesia for the entire lower extremity.

Various approaches have been described to perform sciatic nerve block, including anterior and popliteal approaches. The anterior approach to the sciatic nerve can be performed as easily and successfully under ultrasound guidance as the popliteal approach. The anterior approach is advantageous when combined with a femoral nerve block, as it is performed with the patient in the supine position. Due to ease of application and high success rates, peripheral blocks have begun to be incorporated into anesthesia and postoperative analgesia strategies in ankle surgeries. The use of ultrasonography plays a crucial role in increasing the success rate of the block and reducing potential complications.
