Hand surgery is a branch of surgery that deals with the diseases and treatment of the part of our body called the upper extremity, which starts from the shoulder and extends to the tip of the finger. Our hands are of great importance to meet our basic needs and to be able to produce. Many temporary or permanent problems, especially injuries that impair hand functions, affect our lives significantly. Different structures such as bones, muscles, tendons, vessels, nerves and ligaments in the upper extremity work in harmony in the same environment. Hand surgery is concerned with situations where this harmony is disrupted due to various diseases, traumas, and congenital problems.
