An Anterior superior labral tear is a tear in the front-upper portion of the hip labrum. The labrum is a ring of cartilage that lines the rim of the hip socket. This term is commonly used in orthopedic, sports medicine, and radiology reports about hip pain. It helps describe where the labrum is injured and how that injury may relate to symptoms.

Anterior superior iliac spine avulsion is a type of pelvic avulsion injury near the front of the hip. It happens when a tendon pulls off a small piece of bone from the anterior superior iliac spine (ASIS). It is most commonly discussed in sports medicine and adolescent hip injuries. Clinicians use the term to describe a specific cause of sudden, localized front-of-hip pain after sprinting or kicking.

Anterior superior iliac spine is a bony point on the front edge of the pelvis. You can often feel it as the “front hip bone” on either side. Clinicians use it as an anatomical landmark during hip and pelvis exams. It is also used to plan and check the position of imaging studies and procedures.

Anterior pelvic ring is the front portion of the pelvis that helps form a stable “ring” of bone. It includes the pubic bones, pubic symphysis, and the front parts of the pelvic bones called the pubic rami. Clinicians refer to it when evaluating pelvic pain, pelvic stability, and pelvic fractures. It is commonly discussed in trauma care, sports medicine, and orthopedic surgery planning.

Anterior joint space is the space between the bones at the front (anterior) part of a joint. In the hip, it refers to the gap between the femoral head and the front portion of the acetabulum. Clinicians most often discuss it when reviewing imaging such as X-rays, CT, or MRI. It helps describe cartilage health and how the joint is aligned under load.

Anterior inferior iliac spine morphology describes the size, shape, and position of a small bony landmark on the front of the pelvis. That landmark is the anterior inferior iliac spine (AIIS), located just above the hip socket. Clinicians use this concept mainly in hip pain evaluation, especially when hip motion feels “pinched” in flexion. It is also used in imaging interpretation and surgical planning around the hip.

Anterior inferior iliac spine avulsion is an injury where a small piece of bone is pulled away from the pelvis at the anterior inferior iliac spine (AIIS). It most often happens during sports when a strong muscle contraction tugs on a growth-related bony attachment (an apophysis). Clinicians use this term to describe a specific type of pelvic avulsion fracture and to guide imaging and management. It is commonly discussed in sports medicine, orthopedics, and physical therapy when evaluating sudden front-of-hip pain in adolescents.

Anterior inferior iliac spine is a small bony bump on the front of the pelvis, just above the hip joint. It is part of the ilium (the broad, upper portion of the pelvic bone). It serves as a key attachment point for important hip and thigh structures. Clinicians commonly reference it in physical exams, imaging reports, and hip surgery planning.

Anterior hip precautions are movement and activity guidelines used to protect the hip during early healing. They are most commonly discussed after hip replacement surgery performed through an anterior (front-of-hip) approach. They aim to reduce positions that may stress healing tissues or destabilize the joint. Specific instructions vary by clinician and case.

The Anterior hip capsule is the front portion of the fibrous “envelope” that surrounds the hip joint. It helps keep the ball-and-socket hip stable while still allowing motion for walking, sitting, and sports. Clinicians discuss it often when evaluating hip pain, instability, or stiffness. It is also a key structure during hip arthroscopy, hip injections, and some open hip procedures.
