Delayed wound healing is a potential complication that may occur in the immediate post-operative period following amputation. Factors such as poor circulation, infection, or underlying health conditions can contribute to delayed healing of the surgical wound.
  
a. Phantom limb pain: Phantom limb pain is a sensation of pain, discomfort, or other sensations in the absent limb, but it is not typically an immediate post-operative complication. It may develop later as the nerve endings undergo reorganization.
c. Hypertrophic scarring: Hypertrophic scarring refers to excessive and raised scar tissue formation at the surgical site. While it can occur after amputation, it is not typically an immediate post-operative complication.
d. Contractures: Contractures are abnormal shortening and tightening of muscles and tendons, leading to restricted joint movement. While contractures can develop in the post-operative period, they are not usually immediate complications.
