Primary Outcome Measures

Name	Time	Method

Survey of phantom limb pain, phantm sensation and stump pain in Cambodian and New Zealand amputees. Pain Med 2011 May 12(5):794-98)[At 5 days, 6 months and 1 year post amputation]

Secondary Outcome Measures

Name	Time	Method
Opioid consumption over the 5 days post operatively will be taken from the patients prescription chart and PCA chart. Different opioids will be converted to morphine equivalents by accepted conversion factors. [At 5 days post operatively];Acute pain as assessed using a 11 point numberical rate scale (0 = no pain, 10= worst pain imaginable)[During admission within first five post operative days. ]
