Major Hepatectomy is a surgical procedure that involves the removal of a significant portion of the liver. The liver, a vital organ located in the upper right abdomen, plays a crucial role in various bodily functions, including detoxification, protein synthesis, and the production of biochemicals necessary for digestion. Major Hepatectomy typically refers to the resection of more than three liver segments, which can be necessary for treating various liver conditions.

Joint injections, specifically steroid injections, are a medical procedure designed to deliver anti-inflammatory medication directly into a joint space. This targeted approach aims to alleviate pain, reduce inflammation, and improve mobility in affected joints. The procedure typically involves the injection of corticosteroids, which are synthetic drugs that closely resemble cortisol, a hormone produced by the adrenal glands. These injections are commonly used in various joints, including the knee, hip, shoulder, and spine.

Keloid excision is a surgical procedure aimed at removing keloids, which are raised scars that develop due to an overproduction of collagen during the healing process. Unlike normal scars, keloids extend beyond the original site of injury and can continue to grow over time. They often appear shiny, firm, and can vary in color from pink to dark brown, depending on the individual's skin tone. Keloids can occur anywhere on the body but are most commonly found on the chest, shoulders, earlobes, and cheeks.

Joint Replacement Arthroplasty is a surgical procedure designed to replace a damaged or diseased joint with an artificial implant. This procedure is primarily aimed at relieving pain, restoring function, and improving the quality of life for individuals suffering from joint-related issues. The most commonly replaced joints include the hip, knee, and shoulder, although other joints can also be addressed through this technique.

Joint injections using hyaluronic acid are a medical procedure designed to alleviate pain and improve mobility in joints affected by conditions such as osteoarthritis. Hyaluronic acid is a naturally occurring substance in the body, primarily found in connective tissues, skin, and synovial fluid, which lubricates joints. The procedure involves injecting a gel-like form of hyaluronic acid directly into the affected joint space, where it acts as a lubricant and shock absorber, helping to reduce friction and improve joint function.

Joint arthrodesis, commonly referred to as joint fusion, is a surgical procedure designed to permanently connect two or more bones in a joint, effectively eliminating the joint space. This procedure is primarily performed to alleviate pain and restore function in joints that have been severely damaged due to various conditions. By fusing the bones, the procedure stabilizes the joint, preventing any movement that could lead to further pain or discomfort.

Lymphedema surgery is a specialized medical procedure aimed at alleviating the symptoms associated with lymphedema, a condition characterized by the accumulation of lymphatic fluid in the tissues, leading to swelling, typically in the arms or legs. This condition often arises when the lymphatic system is compromised due to surgery, radiation therapy, infection, or congenital malformations. The primary purpose of lymphedema surgery is to reduce swelling, improve mobility, and enhance the quality of life for individuals suffering from this debilitating condition.

Lumpectomy is a surgical procedure primarily used to treat breast cancer. It involves the removal of a tumor along with a small margin of surrounding healthy tissue. The main goal of a lumpectomy is to excise cancerous cells while preserving as much of the breast as possible. This procedure is often referred to as breast-conserving surgery or partial mastectomy, as it allows patients to maintain their breast shape and appearance post-surgery.

Lumbar spinal fusion is a surgical procedure designed to join two or more vertebrae in the lower back (lumbar region) to eliminate movement between them. This fusion creates a single, solid bone, which can help alleviate pain and restore stability to the spine. The procedure is often performed when conservative treatments, such as physical therapy, medications, or injections, have failed to provide relief for patients suffering from chronic back pain or other spinal conditions.

Low Anterior Resection (LAR) is a surgical procedure primarily aimed at treating rectal cancer and certain benign conditions affecting the lower part of the colon. During this operation, the surgeon removes the lower portion of the rectum along with a segment of the sigmoid colon, which is the part of the large intestine closest to the rectum. The remaining sections of the colon are then reconnected, allowing for the normal passage of stool.
