Experience of 4 Cases of Successful Surgery in Common Peroneal Neuropathy after Posterior Lumbar Decompression Surgery

Introduction : Strangulated common peroneal neuropathy is a well-known cause of foot drop. However, it can also present solely with pain and numbness in the area of the common peroneal nerve, necessitating differentiation from lumbar degenerative diseases. Additionally, it has also been reported to occur after lumbar spinal surgery and may cause failed back surgery syndrome (FBSS). We treated four patients diagnosed with common peroneal neuropathy due to residual or new symptoms in the lower leg following posterior lumbar decompression surgery. All patients underwent common peroneal nerve neurolysis (CPNN) under local anesthesia. Herein, we report our experience with these cases.
