Glossary of Terms
- Acetabular - related to the hip socket
- Acetabulum - hip socket
- Aseptic Lymphocyte Dominated Vasculitis Associated Lesion - (ALVAL) Delayed chronic inflammatory response apparently due to metal sensitivity which may lead to revision of the implants
- Blood Urea Nitrogen - (BUN) the amount of nitrogen in the blood in the form of urea. It is used to evaluate renal function.
- Calcification - hardening of the tissue
- Colonoscopy - test performed by a doctor to view the large intestine (colon) of a patient with a camera
- Congenital Hip Dysplasia - dislocation of the hip at the time of birth due to abnormal development of one or all of the parts of the hip joint: the cup shaped socket in the hip bone; the ball of the thighbone; and the surrounding soft tissues
- Creatinine - A chemical waste product that is generated from muscle metabolism. It is transported through the bloodstream to the kidneys where it is disposed of in the urine
- Cystoscopy - test performed by a doctor to view the urethra and bladder of a patient with a camera
- Degenerative Joint Disease - a condition that causes the loss of cartilage and bone in a joint that eventually leads to pain and loss of function
- Femoral - related to the thighbone (femur)
- Femoral Neck Fracture - breakage of the bone below thehip ball head
- Glomerular Filtration Rate - (GFR) the flow rate of filtered fluid through the kidneys. It is used to evaluate renal function.
- Hematoma - clotted blood vessels that can form in a tissue, organ, or body space that is the result of a broken blood vessel; more commonly referred to as bruising and swelling
- Heterotopic Ossification - deposits of bone in soft tissues around the hip joint. It usually does not affect how well the hip works, but it may decrease the range of motion at the hip. The condition needs surgery only if it causes pain or greatly limits motion.
- Hip Dislocation - a hip problem resulting from a separation of the ball from the socket in a hip replacement device
- Immunosuppressed - a condition where the patient's immune system is not as effective as normal
- Impingement - when excessive pressure is placed on the tissue around the hip resurfacing device
- Magnetic Resonance Imaging - (MRI) is a medical imaging technique commonly used in radiology to visualize the internal structure and function of the body.
- Metal Ions - particles from the hip device that are released into the body as the parts rub against each other
- Metallosis - a bone infection that occurs around the metal hip resurfacing device due to material breakdown or patient sensitivity
- Migration - a hip complication resulting from a movement of the device out of its original position
- Necrosis - death of cells and living tissue caused by external factors, such as infection, toxins, or trauma
- Neurologic - associated with the parts of central nervous system such as the brain, spinal cord, and nerves
- Osteoarthritis - non-inflammatory degenerative disease of the joint characterized by degeneration of cartilage causing pain when the hip bones rub together
- Osteolysis - a condition leading to the loss of bone after total joint replacement
- Osteomalacia - softening of the bones
- Osteonecrosis or Avascular Necrosis - a loss of blood supply to the hip bones characterized by changed shape and increased thickness of the bone, a flattening of the joint surface
- Osteoporosis - a condition leading to bone loss that causes the bones to become brittle and weak
- Perforation - a hole or break in the pelvic bone. Perforation occurs when erosion, infection, or other factors create a weak spot in the bone of the pelvis.
- Pseudotumor - an enlargement that resembles a tumor, resulting from inflammation, fluid accumulation, orother causes
- Rehabilitation - doctor prescribed exercises that help improve hip movement
- Revision Surgery - replacement of a resurfacing hip device with a new total hip device. Revisions can be required due to several reasons such as bone fracture, dislocation, infection, or migration of any device component
- Rheumatoid Arthritis - chronic inflammatory disease that results in joint pain, stiffness and swelling. The disease process leads to severe and, at times, rapid deterioration of multiple joints, resulting in severe pain and loss of function
- Sigmoidoscopy - test performed by a doctor to view the lower large intestine (lower colon) of a patient with a camera
- Subluxation - partial dislocation of a joint
- Traumatic Arthritis - swelling, redness, and pain in a joint resulting from an injury and identified by breakdown of the bone and soft tissue, bleeding in the joint space, increased thickness of the bone, a flattening of the joint surface, joint soft tissue separation from the underlying bone, and breakdown of the bone
- Traumatic Wound - an injury caused by something outside the body
- Trochanteric Bursitis - swelling of the large sacs that separate the hip bones from the muscles and tendons of the thighs and buttocks. This results in tenderness on the upper, outside portion of the thigh bone
- Urinary Catheterization - the insertion of tubing (catheter) into the bladder to aid in the emptying of urine from the bladder
