Acetabulum: The socket of the hip bone, into which the head of the femur fits.
LMWH : Low Molecular Weight Heparin, syringes that you get for 6 weeks in the subcutaneous fat fold to prevent phlebitis after a THP
Phlebitis : venous inflammation resulting in thrombosis
Trombosis: formation of a blood clot or blood clot in a blood vessel

Artery: by which blood (which has been oxygenated) is conveyed from the heart to all parts of the body
Luxation : dislocation; during hip dislocation, the hip head comes out of the hip socket
Infection : contamination of an organism (human) with germs; infection ≠ inflammation

Bacteria: single-cell microorganism of the order of 0.1-10μm
Virus: infectious biological unit without cell structure in contrast with bacteria
Inflammation: tissue reaction to a harmful stimulus, this is classically characterized by 5 signs: redness, swelling, heat, pain and impaired function. Everyone who undergoes surgery will do some kind of inflammatory reaction as a result of the operation itself. This is completely normal and is treated with ice application and adjusted medication that you will receive the first days after the operation to minimize the nuisance of the inflammation.
NSAID: Non Steroïdal Anti Inflammatory Drug; this means that the medicine works anti-inflammatory but does not belong to the cortisone family.
Cortisone: a natural substance that normally occurs in the body and is produced by the adrenal gland; also exists as a medicine and works anti-inflammatory
PAO: Para-articular ossification of bone formation in the vicinity of the joint
Epidural anesthesia: numbing by injecting an anesthetic into the epidural space
Epidural space: the space between the dura mater and the side of the spinal canal
Dura mater: the outer, hard spinal cord membrane
Narcosis : reversible state of general anesthesia and unconsciousness, deliberately induced by medication
Nausea : sickness
TED socks : Trombo Embolism Deterrent socks, elastic socks worn by patients after an operation to prevent thromobis or an embolism.
Aseptic necrosis or osteonecrosis : localized bone death due to poor blood supply to an area of bone
Osteofyt: small, irregular bone growth in the vicinity of a joint secondary to osteoarthritis
Dysplasia : abnormal development
Congenital hipdysplasia: congenital malformation of the hip joint with a tendency to develop poorly
CDH: Congenital Dysplasia of the Hip
Snapping hip: hip joint that gives a crackling sound when a tendon glides over a bone end
Infusion: intravenous administration of fluid and / or medication, without pressures other than gravity
Intraveneous: in a vein
Brackets: The skin is closed with hooks that can be easily removed 14d after the procedure
ECG: Electrocardiogram. Registration of the electical activity of the heart
RX Thorax: radiography of the lungs
Lungembolism: an embolism that is stuck (blood clot) in a blood vessel of the lungs
Recovery: awakening room where you are observed a few hours after the surgery before returning to your room
Drain of Redon: flexible plastic hose that is left behind in an operating area, with a vacuum bottle at the other end.
Coxarthrosis: wear of the hip joint
Joint capsul: casing of the joint
Labrum: Spherical shore around the hip bowl
Synovium: synovial membrane; a membrane that coats the joint capsule and secretes synovia
Synovia: Joint liquid
Trochanter: leg extension of the femur
rheumatism: an inflammatory process of muscles and joints
Artificial pan: acetabular component of the hip replacement that is clamped in the pelvis
Prosthesis stem: femoral component of the hip prosthesis that is clamped in the femur
Stainless steel: The term steel refers to a family of alloys consisting of iron and carbon. By, among other things, varying the carbon content, steels with many different properties can be manufactured. When Chromium is associated with levels higher than 12%, it will disappear typically rusting and stainless steel will be obtained. Again there are different types of stainless steel. For surgical implants, the 316L alloy is mainly used, which also contains Nikel and Molybdenum in addition to Chromium. The L means that the carbon content is kept low for better resistance to corrosion.
In the 1930s these alloys were introduced to manufacture orthopedic implants because they were more resistant to corrosion than the stainless steels at that time.
Titanium alloys: An alloy that has been used since the sixties for the production of prosthetic material. This material was originally introduced because it is extremely resistant to corrosion and because it does not contain Cobalt, Chromium or Nikel. In other words, it is extremely biocompatible. Later on, another advantage became clear: the stiffness of titanium alloys is half of Cr / Co alloys or stainless steel and thus comes closer to the stiffness of bone. This also prevents the phenomenon of stress-shielding.
Biocompatible: this means that there are no rejection reactions by the body
Bioinertic: this means that there are no rejection reactions by the body
Beencement: The most frequent form is PMMA bone cement. PMMA stands for Polymethyl Methacrylate. This is a polymer with the same basic composition as Plexiglas. PMMA was discovered as biocompatible material when the plexiglass, which was used for windscreens of aircraft, came into the eyes of pilots and did not cause an immune response of the body. The first applications were in dentistry. In the 1960s it was introduced to fix orthopedic implants in the bone. It was mainly the orthopedic surgeon Sir John Charnley who announced the use of cement worldwide.
Ultrahigh Molecular Weight PolyEthylene:
UHMWPE is a thermoplastic polymer that is bioinertic in large form. The medical application of PE is only a small fraction of the much larger industrial application. UHMWPE was commercially introduced in 1955 and used for the first time in hip prostheses in 1963.
