Acetabular dysplasia is a condition where the hip socket does not adequately cover the ball of the hip joint. It can lead to hip pain, instability, and early wear of joint cartilage over time. Acetabular dysplasia is commonly discussed in orthopedics, sports medicine, and hip preservation care. It is also referenced in imaging reports and pre-surgical planning for hip procedures.
Acetabular dome is the upper, weight-bearing region of the hip socket (the acetabulum). It is the area where the femoral head most commonly presses during standing and walking. Clinicians often refer to it on hip X-rays, CT scans, and MRI reports. It is also a key landmark in planning and evaluating hip surgery.
An Acetabular cup is an implant that replaces the socket side of the hip joint. It is one of the core components used in total hip replacement (total hip arthroplasty). It sits in the pelvis where the natural acetabulum (hip socket) is located. It helps create a smooth bearing surface for the hip to move.
Acetabular component migration means a hip replacement cup has shifted position inside the pelvis. It is most commonly discussed after total hip arthroplasty (total hip replacement). Clinicians use it as a way to describe and measure implant stability over time. It is usually detected on imaging rather than “felt” directly.
Acetabular cartilage is the smooth joint cartilage that lines the socket side of the hip joint (the acetabulum). It helps the hip move with low friction while spreading loads across the socket. Clinicians discuss it when evaluating hip pain, stiffness, mechanical symptoms, or arthritis. It is also a key structure assessed during hip imaging and hip arthroscopy.
Acetabular anterior column is an orthopedic term for the front “pillar” of bone that helps form the hip socket (acetabulum). It describes how key parts of the pelvis connect and transmit body weight into the hip joint. Clinicians use it most often in acetabular fracture descriptions, CT/X-ray interpretation, and surgical planning. It is a concept in anatomy and fracture care, not a medication or device by itself.
ACEA measurement is a radiographic angle used to describe how much the front (anterior) part of the hip socket covers the femoral head. It is most commonly measured on a specific hip X-ray view called the false-profile view. Clinicians use it to help assess hip stability, acetabular dysplasia, and conditions related to hip impingement. It is a measurement tool, not a treatment.
ABIS is a term used for an anterior-based, intermuscular approach to hip surgery. It most commonly comes up when discussing surgical approaches for total hip arthroplasty (hip replacement). In plain language, it describes reaching the hip joint through a natural interval between muscle groups. Exact naming and what a surgeon includes under “ABIS” can vary by clinician and case.
An Abductor tendon tear is a tear of the tendons that help move the hip sideways and stabilize the pelvis during walking. It most often involves the gluteus medius and/or gluteus minimus tendons on the outer side of the hip. Clinicians use this term to describe a recognized cause of lateral hip pain, weakness, and limping. It is commonly discussed in orthopedics, sports medicine, and physical therapy when evaluating persistent “outer hip” symptoms.
Abductor tendon repair is a surgical method to reattach or fix torn hip abductor tendons. These tendons most often involve the gluteus medius and gluteus minimus near the outside of the hip. It is commonly used to address persistent lateral hip pain and weakness related to tendon tearing. It may be performed through an open incision or with minimally invasive endoscopic techniques.
