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.

Trunnionosis is wear and corrosion at the junction where the femoral head connects to the femoral stem in a total hip replacement. It can release microscopic metal debris and metal ions into the hip area. Clinicians most often discuss Trunnionosis when evaluating pain, swelling, or tissue reactions after hip arthroplasty.

Trendelenburg after hip replacement refers to a hip drop or trunk-lean pattern seen when standing or walking after a hip arthroplasty. It is commonly described using the **Trendelenburg sign** (a physical exam finding) or **Trendelenburg gait** (a walking pattern). In plain terms, it usually indicates that the muscles on the outside of the hip are not stabilizing the pelvis well. Clinicians use it in follow-up visits and rehabilitation settings to assess hip abductor function.

Trendelenburg sign is a clinical finding seen during a simple one-leg standing test. It describes a drop of the pelvis on the side of the lifted leg. It usually suggests weakness or poor function of the hip abductor muscles on the standing leg. It is commonly used in orthopedic, sports medicine, and physical therapy exams for hip and gait concerns.

Trendelenburg gait is a walking pattern where the pelvis drops on the “swing” side when a person stands on the affected leg. It usually reflects weakness or impaired control of the hip abductor muscles, especially the gluteus medius and gluteus minimus. Clinicians commonly use it as a visible clue during a gait exam and in physical therapy or orthopedic evaluations. People may notice it as a “hip drop,” a side-to-side sway, or a limp that worsens with fatigue.

Trochanteric tubercle is a small bony prominence on the upper (proximal) femur. It sits near the greater trochanter, along the ridge between the greater and lesser trochanters. Clinicians use it as an anatomic landmark and as a reference point for muscle and tendon attachment. It most often comes up in hip anatomy, imaging interpretation, and hip or femur surgery discussions.

The Trochanteric region is the outer upper area of the thigh where the femur’s bony prominences (the trochanters) sit near the hip. It is best known as the area around the **greater trochanter**, a palpable bump on the outside of the hip. Clinicians use the term to describe pain location, examine tendon and bursa problems, and plan imaging or procedures. Patients often recognize it as “side-of-hip” tenderness or pain when lying on one side.

Trochanteric pain syndrome is a common cause of pain on the outside of the hip. It is a clinical umbrella term for conditions around the greater trochanter (the bony prominence on the side of the upper thigh bone). It is used in orthopedics, sports medicine, and physical therapy to describe lateral hip pain patterns. It often involves the hip abductor tendons and nearby soft tissues rather than the hip joint itself.
