Zona orbicularis is a circular band of fibers within the hip joint capsule. It wraps around the femoral neck like a ring and helps the hip stay stable. Clinicians most often discuss it when evaluating hip stability and during hip arthroscopy. It is an anatomic structure, not a device or medication.

Walker training is the structured teaching and practice of walking with a walker (a mobility aid). It is commonly used in orthopedic rehabilitation after hip, knee, or leg injury or surgery. It focuses on safe gait (walking pattern), balance, and weight-bearing control. It is typically guided by physical therapists and orthopedic care teams in clinics, hospitals, and home-health settings.

Wiberg angle is an X-ray measurement used to describe how much the hip socket covers the ball of the hip joint. It is also called the center-edge angle (CEA) and is most commonly measured on an anteroposterior (AP) pelvis radiograph. Clinicians use it to help evaluate hip shape, stability, and load distribution across the joint. It is frequently discussed in hip dysplasia and femoroacetabular impingement (FAI) assessments.

Weight-bearing dome is an orthopedic term for the main load-bearing area of a joint surface. In hip care, it most commonly refers to the superior (upper) part of the acetabulum—the socket of the hip. Clinicians use it as a practical landmark when describing imaging findings, injury patterns, and surgical plans. It helps focus attention on the part of the joint where forces are typically highest during standing and walking.

Weight bearing as tolerated is a common orthopedic instruction about how much body weight you may place through an injured or operated limb. It generally means you may put as much weight through the leg or hip as you can comfortably tolerate. It is most often used after fractures, joint replacement, and many soft-tissue surgeries. It is also used in rehabilitation plans guided by orthopedics and physical therapy.
