Aseptic loosening femoral stem is a type of hip replacement failure that happens without infection. It means the femoral stem (the thighbone component of a hip implant) is no longer firmly fixed to bone. It is most often discussed after total hip arthroplasty (total hip replacement) or revision hip surgery. It can cause pain, decreased function, and sometimes implant instability over time.

Aseptic loosening acetabular component is a common long-term failure mode of total hip replacement. It means the hip socket implant (the acetabular component, or “cup”) becomes loose without an infection. It is most often discussed when a person has new or worsening hip pain years after hip arthroplasty. Clinicians use the term during evaluation, imaging review, and planning for possible revision surgery.

An AP pelvis radiograph is a standard X-ray image of the pelvis taken from front to back. It shows both hip joints and the bony ring of the pelvis in a single view. It is commonly used in emergency care, orthopedic clinics, and pre- and post-operative hip evaluation.

AP pelvis is a standard X-ray view of the pelvis taken from front to back. “AP” means anteroposterior, describing the direction the X-ray beam travels. It is commonly used in orthopedics, sports medicine, emergency care, and pre- or post-operative assessment. It helps clinicians see both hip joints and key pelvic landmarks on a single image.

The AP hip view is a standard X-ray image of the hip taken from front to back. “AP” means anteroposterior, describing the direction the X-ray beam travels. It is commonly used in orthopedic clinics, emergency settings, and pre- and post-operative care. It helps clinicians evaluate hip bones, joint spacing, and overall alignment.

Antalgic gait is a walking pattern people use to reduce pain. It often looks like a limp with a shorter time spent standing on the painful leg. It is commonly discussed in orthopedics, sports medicine, and physical therapy. Clinicians use the term as a descriptive finding during a gait exam.

Anterolateral portal is a small skin entry site used to access a joint with an arthroscope and surgical instruments. It is most commonly discussed in the context of hip arthroscopy. The term describes the portal’s position: toward the front (anterior) and side (lateral) of the hip. Clinicians use it to view and treat structures inside and around the hip joint through minimally invasive incisions.

Anterolateral approach THA is a surgical pathway used to perform a total hip arthroplasty (total hip replacement). It describes how the surgeon reaches the hip joint through tissues on the front-side and outer-side of the hip. The goal is to access the ball-and-socket joint while protecting important muscles, tendons, and nerves as much as possible. It is commonly used in elective hip replacement for arthritis and other joint-destructive conditions.

Anterior approach THA is a way to perform total hip arthroplasty (total hip replacement) through an incision at the front of the hip. It is a surgical approach, meaning it describes the pathway the surgeon uses to reach the hip joint. It is commonly used for treating painful hip arthritis and other conditions that damage the hip joint. It is performed in hospitals and surgical centers by orthopedic surgeons.

The Anterior wall acetabulum is the front rim and bony boundary of the hip socket. It helps form the cup that holds and supports the head of the femur (thigh bone). It is commonly referenced in hip imaging, hip pain evaluation, and acetabular fracture care.
