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.
Femoral nerve palsy is reduced function of the femoral nerve, usually causing leg weakness and altered sensation. In plain terms, it can make it harder to lift the thigh or straighten the knee, and it can cause numbness in the front of the thigh. It is most commonly discussed in orthopedics, neurology, sports medicine, and rehabilitation. Clinicians also use the term around hip, pelvic, and spine conditions, including after certain surgeries or injuries.
Femoral nerve is a major peripheral nerve of the lower limb. It carries motor signals to key hip and knee muscles and sensory signals from the front of the thigh and inner lower leg. It is commonly discussed in hip pain evaluations, nerve blocks for surgery, and nerve testing. It is also relevant in some sports, trauma, and post-surgical nerve symptoms.
Femoral neck stress fracture is a small crack or injury in the femoral neck, the narrow part of the thigh bone just below the hip ball. It develops from repeated loading over time rather than a single major fall or collision. It is commonly discussed in sports medicine, orthopedics, and military or endurance training settings. It can also occur in people with bone weakness, where normal daily forces may be enough to cause injury.
