Amputations are categorized into two main types based on the wound condition and surgical technique: open amputation and closed amputation.

Open Amputation: In this method, after the limb is removed, the wound surface is not covered with skin and is managed with open dressings. Open amputation is generally preferred in situations with a high risk of infection (e.g., severe infections or complications due to vascular diseases). It can also be applied when there isn't enough healthy skin tissue in the area to be amputated to cover the wound.

Closed Amputation: This method is performed when there is sufficient healthy skin and soft tissue available to cover the wound surface after amputation. After the limb is surgically removed, the tissues and skin in the surgical wound are carefully brought together and closed. This completes the amputation process without leaving an open wound, thereby supporting the healing process.
