50 patients, between 50-90 years old, with an ASA score of 2-3 who were scheduled to receive surgery due to various lower extremity pathologies, were placed in 1 of 2 treatment groups to test the effectiveness of various forms of anesthesia before surgery: The first group, named the spinal anesthesia group, received a common spinal anesthesia before treatment, while the second group, named the Combined sciatic nerve/lumbar plexus block (CSLPB) group, was given a combined sciatic nerve/lumbar plexus block before surgery began. Results showed that while both preoperative methods are effective in terms of lower extremity orthopedic surgery, CSLPB preparation takes a significantly longer than the standard SA treatment. Surgeons and patients showed no preference to either surgery.
