A recent article links some nerve damage after hip surgery to inflammatory neuropathy. Historically, nerve damage from hip surgery has been attributed to mechanical factors caused by anesthesiologists or surgeons, such as positioning of the patient during surgery or direct surgical injury of the nerves. In this study, researchers examined patients who developed inflammatory neuropathies, where the immune system attacks the nerves, leading to weakness and pain. Inflammatory neuropathies may be treated with immunotherapy.
