In hip joint replacement surgery, can be broadly divided into two kinds,cemented artificial hip and cementless artificial hip, due to the selection of different materials, the price is also very different.
Total cementless hip system indications
1.The main purpose of total hip replacement is to relieve hip pain,and the second is to improve hip function. The main indication for total hip arthroplasty is hip pain caused by hip lesion over 60 years old,which can not be used for other operations but only for head and neck resection.
2.Replacement surgery may be considered in patients over 45 years of age with subluxation of the hip,traumatic arthritis, pain, or loss of function.Due to the insufficient depth of the acetabulum,the upper margin of the acetabulum is inclined, which affects the stability of the acetabulum cup,and the acetabulum should be deepened or covered.
3.Indications of the need for replacement include hip pain due to loosening of the prosthesis,stem fracture,prosthesis dislocation, manual reduction failure,central dislocation caused by acetabulum wear caused by prosthesis and pain.

Generally , the cemented type is suitable for osteoporosis, poor bone conditions, 65 to 70 years of age and older patients. The use of bone cement for artificial hip joints allows for early mobility, which is also suitable for older patients. In addition, elderly patients are generally less active, artificial joint wear is also light, replacement of an artificial joint can be, generally need less revision. The price of bone cement type artificial joint is low.
Cementless type is also known as biological fixation type, suitable for young and middle-aged patients with good bone conditions, such artificial joints have micropores or biological coating materials on the surface, bone can grow into it to achieve the role of fixing artificial joints, so it is often called biological fixation type. Cementless artificial hip joints allow their bones to slowly grow together with the artificial joint to achieve a fixed role.
How to ensure safe wintering of sheep
To ensure the health and survival of sheep through winter, proper management during autumn is essential. Grazing should be extended as much as possible before the first frost, taking advantage of the remaining warm days. Sheep should graze during the day to maximize their intake of grass, and if needed, grazing time can be prolonged in the late afternoon. This ensures that each sheep gets enough food before the cold sets in. After the harvest season, it's important to move the flock to fields where crops have been collected, allowing them to feed on leftover grains, weeds, and crop residues. This practice not only helps the sheep gain strength but also prepares them for the winter ahead.
During winter, sheep need a consistent supply of high-quality forage. Grasses, leaves, rapeseed foliage, and crop stalks should be gathered in advance and stored using methods like ammoniation, alkalization, silage, or fermentation. In addition to roughage, concentrates such as corn, barley, bran, and agricultural by-products are crucial for maintaining energy levels. A balanced diet with diverse ingredients improves palatability and nutrition, ensuring the sheep stay healthy throughout the cold months.
Keeping the sheep in a warm shelter is vital. The saying “A warm pen is a three-point circle†highlights the importance of insulation. Before winter, the sheepfold must be repaired to prevent drafts and maintain warmth. Covering windows with plastic film and hanging straw curtains at night can help retain heat. The floor should remain dry and free from ice to avoid dampness, which can lead to illness. A well-insulated enclosure reduces heat loss and minimizes the risk of cold-related diseases.
Pregnant ewes require special attention. They should not be left idle in the pen, as movement is important for both their health and the development of the fetus. Controlled grazing in sunny areas, avoiding strong winds, is recommended. During the day, they can graze, and at night, they should be fed with hay, root vegetables, and mineral supplements to meet their increased nutritional needs.
Salt and water play a key role in maintaining digestive health. Adding a small amount of salt to drinking water can stimulate appetite and aid digestion. However, the water should be warm, not icy, to avoid sudden drops in body temperature, especially for pregnant sheep. Cold water can cause discomfort and even lead to miscarriage. If warm water isn't available, deep well water can be used, but it should be brought to room temperature before feeding.
Finally, safety is crucial, especially for pregnant sheep. Avoiding steep slopes and preventing overcrowding during grazing is necessary to avoid accidents. The area should be kept calm and free from disturbances. Pregnant sheep should not be taken too far from home to prevent exhaustion or premature labor. In severe weather, extra care must be taken to ensure safe delivery and protect both the mother and the lamb.
