Vastus lateralis is a large muscle on the outer (lateral) front of the thigh. It is one of the four quadriceps muscles that straighten the knee. Clinicians discuss it often in knee rehabilitation, sports medicine, and gait (walking) assessment. It is also a common site for intramuscular injections and muscle testing.

Vastus intermedius is one of the four muscles that make up the quadriceps in the front of the thigh. It sits deep under the rectus femoris muscle and attaches to the femur and the kneecap region through the quadriceps tendon. It is best known for helping straighten the knee and support everyday movements like walking, standing, and climbing stairs. Clinicians commonly reference it in orthopedic exams, sports medicine, physical therapy, and surgical rehabilitation.

VTE prophylaxis means steps taken to reduce the risk of blood clots forming in the veins. It is commonly used around orthopedic injuries and surgeries, especially hip and knee procedures. It can include medications, mechanical devices, and early movement strategies. The goal is prevention, not treatment of an existing clot.

Venous thromboembolism prophylaxis means steps used to help prevent blood clots in veins. These clots most often include deep vein thrombosis (DVT) and pulmonary embolism (PE). It is commonly used around orthopedic surgery, hospitalization, and periods of limited mobility. It may involve medications, mechanical devices, and early movement strategies.

The Vancouver classification is a system doctors use to describe fractures that happen around a hip replacement implant. It is most commonly used for periprosthetic femoral fractures, meaning fractures in the thigh bone (femur) near a hip stem. It helps organize what the fracture looks like, where it is located, and how stable the implant and surrounding bone are. Clinicians use it to guide communication, decision-making, and documentation in orthopedic care.

Vancouver C is a fracture classification term used in hip replacement care. It describes a femur (thigh bone) fracture that occurs well below a hip implant’s stem tip. It is part of the Vancouver classification system for periprosthetic femoral fractures. Clinicians use it to communicate fracture location and guide treatment planning.

Vancouver B3 is a label in a medical classification system for fractures that occur around a hip replacement stem. It describes a specific pattern: a break near the femoral implant with a loose stem and poor surrounding bone quality. Clinicians use it most often in the setting of periprosthetic femoral fractures after total hip arthroplasty (hip replacement). It helps standardize communication and guide planning for treatment and follow-up.

Vancouver B2 is a classification label for a specific type of femur fracture around a hip replacement stem. It describes a fracture near the implant where the femoral stem is loose, but the surrounding bone stock is generally adequate. It is most commonly used after total hip arthroplasty (hip replacement) to guide evaluation and treatment planning. It is part of the broader Vancouver classification system for periprosthetic femoral fractures.

Vancouver B1 is a label used to classify a specific kind of femur fracture near a hip replacement. It describes a fracture around the femoral stem where the implant is considered stable. It is most commonly used after total hip arthroplasty (hip replacement) to guide treatment planning. It is part of the “Vancouver classification” system for periprosthetic femoral fractures.

Vascular injury THA means damage to an artery or vein related to total hip arthroplasty (THA), also called total hip replacement. It is an uncommon but potentially serious complication rather than a planned part of surgery. It can happen during surgery or appear later as bleeding, clotting, or reduced blood flow to the leg. The term is commonly used in orthopedic and vascular medicine when discussing THA risks, recognition, and management.
