Spinal Fusion is a surgical procedure that permanently joins two or more vertebrae. Its plain meaning is “making a segment of the spine heal into one solid bone unit.” It is a procedure used in orthopedic spine surgery and neurosurgery to address painful or unstable spinal motion. It is commonly used in degenerative disease, deformity, trauma, tumor, and certain infections when stability is a primary goal.

Arthroscopy is a minimally invasive procedure used to look inside a joint and, when needed, treat joint problems. It is a surgical procedure and also a diagnostic method because it can confirm intra-articular pathology directly. It is commonly used in orthopedic practice for the knee and shoulder, and also for the hip, ankle, elbow, and wrist. It relies on a small camera (arthroscope) and specialized instruments inserted through small incisions.

Hemiarthroplasty is a surgical procedure that replaces only one side of a joint. It is a reconstructive orthopedic procedure (a type of arthroplasty). It is most commonly used in the hip and shoulder, especially after fractures. The goal is to restore joint function and reduce pain while preserving the opposite joint surface.

Arthroplasty is a surgical procedure that restores joint function by replacing or reconstructing part or all of a joint. It is a procedure, most commonly performed for degenerative joint disease and certain fractures. In practice, Arthroplasty is most often discussed in hip and knee care, but it also applies to the shoulder, elbow, ankle, and smaller joints. The goal is typically to reduce pain and improve mobility when the native joint can no longer perform adequately.

Joint Replacement is a surgical procedure that removes damaged joint surfaces and replaces them with implanted components. It is a procedure and an implant-based treatment concept used in orthopedics and musculoskeletal medicine. It is most commonly performed for the hip and knee, and it is also used for the shoulder, ankle, and other joints. Its clinical goal is to reduce pain and improve function when joint disease or injury is advanced.

Total Knee Replacement is a surgical procedure that resurfaces a damaged knee joint with artificial components. It is a reconstructive orthopedic procedure (arthroplasty) used to treat end-stage knee joint disease. It is most commonly performed for advanced degenerative arthritis that limits function and quality of life. In practice, it is discussed in adult reconstruction clinics, perioperative medicine, and rehabilitation settings.

Total Hip Replacement is a surgical procedure that replaces a diseased hip joint with artificial components. It is a reconstructive orthopedic procedure (also called total hip arthroplasty). It is commonly used to treat end-stage hip joint damage that causes pain and functional limitation. It is performed in elective and some urgent settings, most often by orthopedic surgeons.

An Intertrochanteric Fracture is a break in the upper femur between the greater and lesser trochanters. It is a clinical condition and a common subtype of “hip fracture.” It typically occurs after a fall in older adults or high-energy trauma in younger patients. It is commonly evaluated and managed in emergency medicine, orthopedics, geriatrics, and rehabilitation care.

Femoral Neck Fracture is a break through the femoral neck, the narrowed segment connecting the femoral head to the femoral shaft. It is a clinical condition and a major subtype of hip fracture. It commonly presents after a fall in older adults or after high-energy trauma in younger patients. It is frequently discussed in emergency care, orthopedic surgery, geriatrics, and rehabilitation settings.

Hip Fracture is a break in the bone near the hip joint, most often involving the proximal femur. It is a clinical condition, not a single procedure or device. It is commonly evaluated in emergency, inpatient, and perioperative orthopedic care. It is discussed using anatomy-based fracture patterns because location strongly affects treatment and prognosis.
