One of the relatively recent changes in cement and arthroplasty is that a multitude of cements are available on the market. Although the durability of well-made cement mantles around implants is fairly consistent among cements, the products differ in terms of viscosity, working time, and setting. A surgeon must know the details of the particular cement he or she intends to use, as it will influence the cement technique. Working time and setting time vary among the different cements. Data have shown that different types of femoral stems should be inserted with different types of cements.
Therefore, a surgeon who uses a smooth stem should use cement with a longer doughy phase, whereas a surgeon who uses a rougher stem should use cement with a longer liquid phase. Failure to appreciate the working characteristics of the different cements can potentially lead to complications during the surgery.
The efficacy of a type of uncemented total hip replacement was compared with that of a hybrid total hip replacement in which an uncemented acetabular and a cemented femoral component were used. Twenty-five patients who had had a hybrid total hip replacement were matched, by age, weight, sex, and diagnosis, with twenty-five patients who had had an uncemented total hip replacement.
Many conditions can result in degeneration of the hip joint (image). Osteoarthritis is perhaps the most common cause for hip replacement surgery. This condition is commonly referred to as “wear and tear arthritis”. Osteoarthritis can occur with no previous history of injury to the hip joint – the hip simply “wears out”. There may be a genetic tendency in some people that increases their chances of developing osteoarthritis.
The patient’s bone grows directly onto the stem and socket, encouraged by the coating with manufactured bone minerals. The bone then fuses with the new hip components. This bond is very strong and prevents the loosening process meaning a redo operation due to loosening is a rarity.
