Acetabulum – Cup-shaped structure that encloses the head of the femur (thigh bone)

Acetabular Labrum – ring of cartilage that surrounds the acetabulum within the hip socket

Acetabular Retroversion – malorientation of the acetabulum in the sagittal plane; i.e. hip socket tilts backwards

Arthroscopy (Scope) – Surgery that utilizes camera equipment and usually smaller incisions

Computerized Tomography (CT) – is a scan that produces multiple images or pictures of inside of the body. The cross-sectional images can generate three-dimensional images. CT scans provide greater detail than a traditional x-ray, particularly of bones, soft tissues and blood vessels.

Femoral Anteversion – Forward tilt of the hip joint that can often cause inward ‘twisting’ of the thigh bone. Typically causes inward turn of the knees and feet.

Femoral Osteotomy (FO) – an operation to correct specific deformities of the femur

Femoral Retroversion – Posterior tilt of the hip joint that can often cause outward “twisting” of the thigh bone. Typically causes outward turn of the knees and feet.

Femur – thigh bone

General Anesthetic (GA)– uses a combination of medication to put you in a sleep-like state before surgery or medical procedure. You don’t feel pain because you are completely unconscious. A combination of intravenous drugs and inhaled gasses are used to put to you to sleep.

Hip Dislocation – the head of femur comes out of the hip socket

Hip Dysplasia or Developmental Dysplasia of the Hip (DDH)– hip socket does not develop properly; it is shallower and can have an upward slope. The severity can vary, from very severe with recurrent dislocations, to mild

Local Anesthetic – a technique to induce the absence of sensation in a specific part of the body, the aim is generally to produce local insensitivity to pain

Magnetic Resonance Imaging (MRI) – is a scan that uses strong magnetic fields to produce details images of the inside of the body. Often used for more detailed imaging of soft tissues.

Osteoarthritis (OA)– condition related to ‘wear and tear’ of a joint. Joint space narrows and causes bone on bone rubbing; common symptoms include pain and reduced range movement of the joint

Periacetabular Osteotomy (PAO)– an operation to rotate the hip socket.

Stress Fracture – this is a small crack in a bone. These usually occur after hip surgery (but can occur during) as weight-bearing status changes to allow partial or full weight-bearing through the pelvis.

X-rays – Radiographic test to assess the bones.
