Acetabular offset is a hip measurement that describes where the hip socket (acetabulum) sits relative to the pelvis. It helps describe the position of the hip’s center of rotation (the “ball-and-socket” center). Clinicians most often use it in hip imaging reports and in planning or evaluating hip surgery, especially total hip replacement. In simple terms, it helps answer: “How far in or out is the socket and hip center from the pelvis?”

Acetabular notch is a normal groove at the lower (inferior) edge of the hip socket. It is part of the acetabulum, the cup-shaped surface that holds the femoral head. Clinicians refer to it as an anatomic landmark in imaging, hip arthroscopy, and pelvic/acetabular surgery. It is commonly discussed together with the transverse acetabular ligament and the ligament of the femoral head.

An Acetabular liner is a removable insert that fits inside the “cup” part of a hip replacement. It forms the smooth bearing surface where the artificial ball of the hip moves. It is most commonly used in total hip arthroplasty (total hip replacement) and some revision surgeries. Different liner materials and designs are chosen to match the patient’s anatomy and surgical goals.

The Acetabular labrum is a ring of strong fibrocartilage that lines the rim of the hip socket. It helps the hip joint fit, seal, and move smoothly during daily activity and sports. Clinicians commonly discuss it when evaluating hip pain, clicking, or instability. It is also a key structure in hip imaging and hip arthroscopy.

Acetabular labral pathology refers to problems affecting the labrum of the hip socket. The labrum is a ring of fibrocartilage that lines the rim of the acetabulum (the “socket” part of the hip joint). This term is commonly used in orthopedic clinics, sports medicine, physical therapy, and imaging reports when evaluating hip pain. It describes a category of findings rather than a single diagnosis or a single treatment.

Acetabular index measurement is a way to quantify how “sloped” or “shallow” the hip socket is on imaging. It is most commonly measured on a front-view pelvis X-ray, especially in children. Clinicians use it to help evaluate hip development and hip dysplasia. It can also support treatment planning and follow-up comparisons over time.

Acetabular index is a radiographic measurement that describes the slope of the acetabular roof in the hip. It helps clinicians describe how well the hip socket covers the top of the femoral head. It is most commonly used on pelvic X-rays in infants and children, especially when evaluating hip development. It can also appear in research and clinical discussions about hip dysplasia and socket shape.

An Acetabular fracture posterior wall is a break in the back rim of the hip socket (the acetabulum). It is most often associated with high-energy trauma, such as vehicle collisions or falls. Clinicians commonly discuss it in emergency care, orthopedic trauma, and surgical planning. It matters because the posterior wall helps keep the ball of the hip joint stable in the socket.

Acetabular fracture both columns is a specific fracture pattern of the hip socket (the acetabulum). It means both the front (anterior) and back (posterior) “columns” of the socket are broken. This injury usually follows high-energy trauma, such as a motor vehicle collision or a fall from height. It is a term commonly used in orthopedic trauma care, imaging reports, and surgical planning.

Acetabular fracture anterior column is a fracture pattern involving the front “pillar” of the hip socket. It affects the acetabulum, the cup-shaped part of the pelvis where the femoral head (ball) sits. The term is used in orthopedic trauma care to describe the fracture line and plan evaluation and treatment. It is most often discussed after high-energy injury (such as a collision) or a fall in older adults.
