A Spinal Orthosis is an external supportive device used to influence motion and alignment of the spine. It is a **device** (an orthosis) rather than a diagnosis or a surgical procedure. It is commonly used in orthopedic surgery, spine surgery, rehabilitation medicine, emergency care, and physical therapy settings. It is applied to help stabilize, offload, or guide the spine during healing, deformity management, or symptom control.

Orthopedic Casting is a method of external immobilization used to support injured or postoperative musculoskeletal structures. It is a clinical procedure and device-based treatment that uses rigid materials to maintain alignment and limit motion. It is commonly used in emergency departments, orthopedic clinics, fracture services, and perioperative care. It is most often applied to stabilize bone and joint injuries while tissues heal.

Orthopedic Emergency is a time-sensitive musculoskeletal problem that can threaten life, limb, or long-term function. It is a clinical **concept** rather than a single diagnosis, test, or procedure. It is commonly used in emergency departments, trauma care, urgent orthopedics, and perioperative settings. It guides rapid triage, evaluation, and early stabilization of bones, joints, soft tissues, and neurovascular structures.

Orthopedic ICU is a specialized intensive care setting focused on critically ill patients with major musculoskeletal injuries or complex orthopedic surgical needs. It is a clinical care **concept** (a service model), not a single test or procedure. Orthopedic ICU care is commonly used after severe trauma, major spine surgery, or complicated orthopedic infections. In many hospitals, this care occurs within a trauma ICU or surgical ICU with strong orthopedic co-management rather than a separate unit.

An Orthopedic Clinic is a healthcare setting focused on conditions of the bones, joints, muscles, tendons, ligaments, and related nerves. It is a clinical concept rather than an anatomy structure, disease, or single procedure. It is commonly used to evaluate injuries, pain, deformity, and loss of function in the musculoskeletal system. It may also coordinate imaging, rehabilitation planning, injections, and surgical decision-making.

An Orthopedic Ward is a hospital inpatient unit that cares for patients with musculoskeletal injuries and disorders. It is a clinical care concept (a specialized inpatient setting), not an anatomy structure or a single procedure. It is commonly used after orthopedic surgery and for acute trauma admissions that need hospital monitoring. It also supports rehabilitation planning and safe discharge for patients with limited mobility.

Navigation Surgery is a technology-assisted approach that helps surgeons orient instruments and implants in real time during an operation. It is a surgical concept and toolset rather than a single operation. It is commonly used in orthopedics for joint replacement, spine instrumentation, and selected trauma and tumor cases. It aims to translate preoperative plans and patient anatomy into more reproducible intraoperative positioning.

Computer Assisted Surgery is the use of digital tools to help surgeons plan and perform an operation with real-time guidance. It is a clinical concept and set of enabling technologies rather than a single procedure. In orthopedics, it is commonly used to support implant positioning, alignment, and instrument guidance. It is most often seen in joint replacement, spine surgery, and selected trauma and deformity cases.

Robotic Knee Replacement is a surgical procedure that uses a robotic-assisted system to help surgeons perform knee arthroplasty with computer-guided planning. It is a **procedure** (and a technology platform) used in orthopedic surgery for degenerative or destructive knee joint disease. It is most commonly applied to **total knee arthroplasty (TKA)** and, in selected cases, **unicompartmental (partial) knee arthroplasty (UKA)**. In practice, it is used to support implant alignment, bone preparation, and soft-tissue balancing during knee replacement surgery.

Minimally Invasive Surgery is an approach to performing operations through smaller incisions and less tissue disruption than traditional open surgery. It is a clinical **concept and procedural strategy** rather than one single operation. It is commonly used in orthopedics, sports medicine, and spine surgery to diagnose and treat bone, joint, and soft-tissue conditions. It typically relies on specialized instruments and imaging or camera guidance to reach deep structures with limited exposure.
