Varus osteotomy hip is a surgical bone-cutting procedure that changes the angle of the upper thigh bone near the hip. “Varus” means the bone is repositioned so the limb angles slightly inward relative to the hip. It is most commonly used in hip preservation surgery, especially in pediatric and young adult orthopedic care. The goal is to improve hip mechanics by changing how the femoral head sits and loads inside the socket.

Valgus osteotomy hip is a surgical procedure that changes the angle of the upper femur (thigh bone) near the hip. “Valgus” means the bone is repositioned to increase the neck–shaft angle, bringing the leg into a more “outward” alignment at the hip. It is most commonly used to improve how forces pass through the hip joint or a femoral neck fracture site. Orthopedic surgeons use it in selected hip problems in both adolescents and adults.

Unstable intertrochanteric fracture is a type of hip fracture in the upper femur (thigh bone). It occurs in the intertrochanteric region, between the greater and lesser trochanters near the hip. “Unstable” means the broken bone pieces are likely to shift under normal forces, making alignment harder to maintain. The term is commonly used in orthopedic diagnosis, surgical planning, and rehab planning after a hip fracture.

Unipolar hemiarthroplasty is a type of hip replacement surgery that replaces only the “ball” of the hip joint. It uses a single-piece (unipolar) femoral head that moves directly against the patient’s natural hip socket. It is most commonly used for certain hip fractures, especially fractures of the femoral neck. It is considered a partial hip replacement rather than a total hip replacement.

Uncemented hip arthroplasty is a type of hip replacement where the implant is fixed to bone without surgical cement. It relies on a tight initial fit and the body’s bone growth to secure the implant over time. It is commonly used in total hip arthroplasty (total hip replacement) for arthritis and other joint problems. It may also be used in some revision (repeat) hip surgeries, depending on bone quality and implant choice.

Ultrasound-guided trochanteric injection is an image-guided injection performed near the bony prominence on the outside of the hip called the greater trochanter. It is commonly used to target pain generators around the lateral (outer) hip, such as inflamed bursae or irritated gluteal tendons. Ultrasound helps the clinician see soft tissues and guide the needle to a planned location in real time. It is used in orthopedic, sports medicine, and physical medicine settings for both diagnosis and symptom management.

Ultrasound-guided aspiration hip is a procedure that uses ultrasound imaging to guide a needle into the hip joint or nearby fluid collection. The goal is to remove (aspirate) fluid for testing or symptom evaluation. It is commonly used in orthopedics, sports medicine, rheumatology, and emergency care. It may be performed in a clinic, procedure room, or hospital setting depending on the case.

Ultrasound-guided hip injection is a technique for placing a needle into the hip joint or nearby tissues using real-time ultrasound imaging. It is commonly used to deliver medication or to confirm the source of hip pain. It is performed in many orthopedic, sports medicine, and radiology settings. The goal is accurate placement while visualizing nearby muscles, tendons, and blood vessels.

Ultrasound hip is an imaging test that uses sound waves to create pictures of structures around the hip. It is commonly used in orthopedics, sports medicine, and physical therapy clinics. It can show soft tissues like tendons, bursae, muscles, and joint fluid in real time. It is also used to guide certain hip injections and fluid aspirations.

Tuberculous hip is a hip joint infection caused by *Mycobacterium tuberculosis*. It is a form of extrapulmonary (outside the lungs) tuberculosis that affects the joint lining and nearby bone. It usually develops slowly and can look like other causes of chronic hip pain and stiffness. The term is commonly used in orthopedics, infectious disease care, radiology, and physical therapy documentation.
