What is a "spare-part surgery"?

A spare-part surgery is a medical procedure where a damaged or faulty body part is replaced with a healthy one. This can involve organ transplantation, like receiving a new heart or kidney, or using prosthetic devices for limbs or joints. The goal is to restore or improve bodily functions affected by injury, disease, or conditions present from birth. These procedures are crucial for improving quality of life and helping patients regain movement and health.
