ACEA measurement: Definition, Uses, and Clinical Overview

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: Definition, Uses, and Clinical Overview

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.

Abductor tendon tear: Definition, Uses, and Clinical Overview

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: Definition, Uses, and Clinical Overview

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.

Abductor mechanism: Definition, Uses, and Clinical Overview

The Abductor mechanism is the group of muscles and tendons on the outside of the hip that move the leg away from the body and steady the pelvis. It is most commonly discussed in hip pain evaluations, gait (walking) problems, and hip surgery planning. When it is irritated or torn, people may develop lateral (outer) hip pain or a limp. When it is weak, the pelvis may drop to one side during walking.

Abductor insufficiency: Definition, Uses, and Clinical Overview

Abductor insufficiency is reduced strength or function of the hip abductor muscles. It commonly affects walking stability and balance, especially during single-leg stance. Clinicians use the term to describe a pattern of symptoms, exam findings, and sometimes imaging results. It is discussed in hip arthritis care, sports injuries, and after some hip surgeries.
