Femoroacetabular impingement is a hip condition where the ball-and-socket joint does not move smoothly. It commonly involves extra bone shape or tight joint mechanics that cause the femur and acetabulum to bump into each other. It is discussed in orthopedic, sports medicine, and physical therapy settings when evaluating hip or groin pain. It is also used to describe a pattern of hip motion limits and tissue irritation seen in active people and some older adults.

Femoroplasty is a surgical reshaping of the femur near the hip joint. It most commonly targets the femoral head–neck junction to improve hip clearance during motion. Femoroplasty is often performed during hip arthroscopy for femoroacetabular impingement (FAI). It may be combined with treatment of the labrum or cartilage when those tissues are affected.

The Femoral triangle region is a small, clinically important area at the front of the upper thigh, just below the groin crease. It is a landmark doctors use to locate major blood vessels, nerves, and lymph nodes. It is commonly referenced during physical exams, imaging, and some procedures involving the hip and leg circulation. It also helps clinicians describe where groin or anterior hip pain is coming from.

Femoral stem subsidence means the femoral stem has moved downward inside the thighbone after hip replacement. It is most commonly discussed after total hip arthroplasty (total hip replacement) and some hemiarthroplasties. Clinicians use the term to describe a measured change on imaging, not a diagnosis by itself. A small amount may occur as an implant “settles,” while progressive movement can signal a fixation problem.

A Femoral stem is a metal implant placed inside the thighbone (femur). It forms the femoral side of many hip replacements. It is commonly used in total hip arthroplasty and hemiarthroplasty. Its role is to support a new hip ball (femoral head) and transfer load into the femur.

The Femoral shaft is the long, straight portion of the thigh bone (femur) between the hip region and the knee region. It is sometimes called the femoral diaphysis in anatomy. It helps transmit body weight and muscle forces during standing, walking, and running. Clinicians commonly reference it in imaging, fracture care, and orthopedic surgery planning.

Femoral retroversion is a rotational alignment of the thigh bone (femur) where the femoral neck is oriented more backward than expected. In plain terms, it means the “twist” of the femur can point the hip and leg slightly outward. It is discussed in orthopedics, sports medicine, and physical therapy when evaluating hip pain, gait (walking pattern), and impingement-type symptoms. It is an anatomic finding rather than a medication, device, or single treatment.

Femoral offset measurement describes how far the femoral head sits away from the femoral shaft. It is a way to quantify hip “side-to-side” geometry that affects muscle leverage and joint loading. It is commonly used on hip X-rays and advanced imaging during hip evaluation and hip replacement planning.

Femoral offset is a hip measurement that describes how far the femoral head sits away from the femoral shaft. It is commonly assessed on hip X-rays and other imaging studies. Clinicians use it to understand hip mechanics and muscle leverage. It is also used in planning and evaluating hip surgery, especially total hip replacement.

Femoral neuropathy is dysfunction of the femoral nerve, a major nerve that powers the front of the thigh. It can cause weakness with knee straightening and changes in feeling in the front or inner thigh. It is commonly discussed in orthopedics, sports medicine, neurology, and physical therapy when evaluating hip, groin, or thigh symptoms. Clinicians use the term to describe a pattern of nerve-related symptoms and to guide further testing.
