This book presents the latest information on the epidemiology, pathophysiology, diagnosis and treatment of peripheral nerve entrapment neuropathy, focusing on the lumbar spine and the lower limbs. The book is divided into three thematic sections, on para-lumbar spine disease, lower limb entrapment neuropathy, and comprehensive reviews. In addition to exploring the latest advances, it also features short essays by the Editor that provide valuable insights into the disease. Though neuropathy of the upper limbs has been studied in detail and substantial evidence is available, there are very few books on para-lumbar spine and lower limb entrapment neuropathy. Often, the symptoms are misdiagnosed as lumbar spine disease, overlooked, or treated as failed back surgery syndrome. This book provides a comprehensive overview of the disease and shares the latest findings from the last 10 years of research into its diagnosis and treatment, offering essential guidance for general clinicians, spinal surgeons and neurosurgeon who treat numbness and pain in the lower limbs and lower back. It will also benefit young doctors interested in the field, nurses, therapists and patients
