Severe Phantom Leg Pain in an Amputee After Lumbar Plexus Block:

Consensus Statements Regarding the Multidisciplinary Care of Limb Amputation Patients in Disasters or Humanitarian Emergencies: Report of the 2011 Humanitarian Action Summit Surgical Working Group on Amputations Following Disasters or Conflict

Limb amputations are frequently performed as a result of trauma inflicted during conflict or disasters. As demonstrated during the 2010 earthquake in Haiti, coordinating care of these patients in austere settings is complex. During the 2011 Humanitarian Action Summit, consensus statements were developed for international organizations providing care to limb amputation patients during disasters or humanitarian emergencies. Expanded planning is needed for a multidisciplinary surgical care team, inclusive of surgeons, anesthesiologists, rehabilitation specialists and mental health professionals. Surgical providers should approach amputation using an operative technique that optimizes limb length and prosthetic fitting. Appropriate anesthesia care involves both peri-operative and long-term pain control. Rehabilitation specialists must be involved early in treatment, ideally before amputation, and should educate the surgical team in prosthetic considerations. Mental health specialists must be included to help the patient with community reintegration. A key step in developing local health systemsis the establishment of surgical outcomes monitoring. Such monitoring can optimizepatient follow-up and foster professional accountability for the treatment of amputation patients in disaster settings and humanitarian emergencies.

Disappearance of Phantom Limb Pain During Cauda Equina Compression by Spinal Meningioma and Gradual Reactivation After Decompression

We describe a 65-yr-old woman, whose right lower limb had been amputated at the mid-femoral level because of complicated femur fracture sustained at the age of 5 yr. After amputation, she experienced phantom limb pain (PLP), which gradually decreased in intensity but persisted for 60 yr. At this point the pain diminished progressively, in parallel with the evolution of cauda equina compression caused by an intraspinal tumor. The PLP gradually reappeared over 3 mo after surgical removal of the tumor.

IMPLICATIONS

We present a case in which phantom limb pain (PLP) in an amputated leg disappeared during cauda equina compression by meningioma and reactivated after surgical decompression. This case suggests that complete compression or blockade of nerves, a nerve plexus, the cauda equina, or the medullary cord may result in suppression of PLP, and decompression of or recovery from the block may cause reactivation.
