Brief Summary:
Phantom limb pain is a complication of amputation. Although pre-empitve epidural analgesia was once thought to prevent such a com plication, recent studies did not demonstrate this. Peripheral blocks are more powerful then epidurals, and can even influence somatotropic representation in the brain. This a prospective case series in which the investigators hope to show a decrease, against historical control, of the incidence of post-operative amputation lower limb phantom pain. The investigators established the block at least 24 hours pre-operative and continue it for at least 2 days. Patient are followed daily for the 1st 3 days and then up to 3 month for the incidence of phantom limb pain. The investigators hope to recruit 30 patients.

Actual Enrollment : 17 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: a Prospective Case Series of Pre-emptive Pre-amputation Sciatic Nerve Block to Prevent Lower Limb Phantom Pain
Study Start Date : January 2005
Actual Primary Completion Date : September 2007
Actual Study Completion Date : September 2007

Arm Intervention/treatment
Experimental: sciatic block
One arm, all patient studied received a block
Procedure: sciatic nerve block
Sciatic nerve block, Labatt approach, with a stimuplex needle and catheter. Once localized, a bolus of 20 mL ropivacaine 1,0% is given through the catheter and is followed by a perfusion of ropivacaine 0,2% 6-10 mL/hre for at least 24 hours pre-op and 48 hours post-op

Primary Outcome Measures :
  1. incidence of lower limb phantom pain [ Time Frame: 3 month post amputation ]
