[Peripheral nerve blocks for a patient with spondylolysis undergoing anterior cruciate ligament reconstruction].

A 24-year-old man, 178 cm tall and weighting 82 kg, underwent anterior cruciate ligament reconstruction. We gave general anesthesia and ultrasound-guided combined femoral and sciatic nerve block. Neuraxial blocks increase the risk of neuropathy in the patient with spondylolysis compared with peripheral nerve blocks. In this report, we describe the successful postoperative pain control with peripheral nerve blocks to a patient with spondylolysis.
