The FABER test is a common physical exam maneuver used to assess hip and pelvic pain. FABER stands for **Flexion, ABduction, and External Rotation**—the positions placed on the tested leg. It is often performed in orthopedic, sports medicine, and physical therapy settings. Clinicians use it to help localize symptoms to the **hip joint** or the **sacroiliac (SI) region**.

The FADIR test is a hands-on physical exam maneuver used to evaluate hip and groin pain. FADIR stands for **Flexion, ADduction, and Internal Rotation** of the hip. Clinicians commonly use it in orthopedics, sports medicine, and physical therapy settings. It helps assess whether hip motion reproduces symptoms suggestive of intra-articular (inside-the-joint) irritation.

Frog-leg view is a specific X-ray position used to image the hip joint. It is commonly called a “frog-leg lateral” view because the legs resemble a frog’s posture. It helps clinicians see the femoral head and femoral neck more clearly than some standard views. It is used in orthopedics, sports medicine, emergency care, and pediatric hip evaluation.

Frog-leg lateral is a specific X-ray view used to image the hip joint. It gets its name from the leg position, which resembles a “frog-leg” posture. It is commonly performed in radiology departments, urgent care, and orthopedic clinics. Clinicians use it to better see the femoral head and neck from the side.

The Frank-Starling mechanism describes how the heart automatically pumps more blood when it fills with more blood. In simple terms, a fuller heart contracts more strongly—up to a point. Clinicians use it to understand changes in blood pressure, heart output, and fluid status. It often comes up around surgery, rehabilitation, and exercise tolerance discussions.

Fracture line femoral neck refers to the visible break line through the femoral neck, the narrow “bridge” of bone between the femoral head and the femur shaft. It is most commonly used in radiology reports and orthopedic notes when describing hip fractures. The location and direction of this fracture line help clinicians communicate severity and plan care. It is a descriptive term, not a treatment by itself.

False profile view hip is a specific X-ray view used to look at the front (anterior) part of the hip joint. It is an oblique pelvic radiograph taken with the pelvis rotated rather than facing straight forward. Clinicians use it to better assess how well the hip socket covers the femoral head in the front. It is commonly used in orthopedic clinics, sports medicine, and hip-preservation evaluations.

A Fluoroscopy-guided hip joint injection is an injection placed into the hip joint using real-time X-ray imaging for guidance. It is commonly used in orthopedics, sports medicine, and pain-focused musculoskeletal care. It may be used to help diagnose the source of hip pain or to deliver medication for symptom relief. The goal is accurate placement inside the hip’s ball-and-socket joint space.

Fluoroscopic aspiration hip is a needle procedure used to remove fluid from the hip joint under live X-ray guidance. It is most often done to help diagnose the cause of hip pain, swelling, or fever. It can also be used to reduce pressure from a joint effusion (extra joint fluid) in selected cases. This technique is commonly used in orthopedic clinics, hospitals, and interventional radiology settings.
