2. Indications to Amputations 1. Trauma and its complications (anaerobic infection, osteomyelitis) 2. Malignant tumors of skeleton and soft tissues of limbs 3. Vascular diseases (thrombosis, diabetic angiopathy, obliterating endarteritis)

3. Classification of Amputations Primary amputation (within first 24 hours) Primary amputation (within first 24 hours) Secondary amputation (7-8 days after injury) Secondary amputation (7-8 days after injury) Re-amputation (repeated amputation) Re-amputation (repeated amputation)

4. Levels of Amputations

5. Steps of Amputation I. Cutting of soft tissue II. Treatment of periosteum and cutting of bone III. Stump treatment

6. Types of Amputations (according to soft tissues cutting) 1. Flap amputations: - single-flap amputation - single-flap amputation - double-flap amputation - double-flap amputation 2. Circular amputations: - one-step (guillotine) amputation - one-step (guillotine) amputation - two-step amputation (variety – “cuff” method of forearm amputation) - two-step amputation (variety – “cuff” method of forearm amputation) - three-step (conical-circular) amputation - three-step (conical-circular) amputation

18. The most common complications of amputation are: massive haemorrhage that occurs when a suture becomes loose massive haemorrhage that occurs when a suture becomes loose massive haemorrhage massive haemorrhage infection infection rash, blisters, and skin breakdown caused by immobility, pressure, and other sources of irritation rash, blisters, and skin breakdown caused by immobility, pressure, and other sources of irritation pneumonia, blood clots, and breathing problems associated with immobility pneumonia, blood clots, and breathing problems associated with immobility pneumonia formation of nerve cell tumors (neuromas) at severed nerve endings formation of nerve cell tumors (neuromas) at severed nerve endingstumors

Complications of Amputation Mistakes of I step of amputation: Mistakes of I step of amputation: 1. conical stump 1. conical stump 2. mace-shaped stump 2. mace-shaped stump Mistakes of II step of amputation: Mistakes of II step of amputation: 3. terminal necrosis of bone 3. terminal necrosis of bone 4. forming of large osteophytes 4. forming of large osteophytes Mistakes of III step of amputation: Mistakes of III step of amputation: 5. forming of trophic ulcers 5. forming of trophic ulcers 6. phantom pain 6. phantom pain 7. Chronic osteomyelitis caused by secondary infection inside a wound 7. Chronic osteomyelitis caused by secondary infection inside a wound
