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.
African geese feeding technology
African geese, belonging to the duck family and classified as a herbivorous waterfowl, are native to Africa and South America. Their tenderloin meat is highly nutritious, containing 20.98% protein, with a delicate texture and rich flavor. This lean meat is low in fat and cholesterol, making it an excellent source of essential nutrients. It is packed with amino acids, unsaturated fatty acids, and various vitamins that support overall health. In terms of minerals, it contains 46.6 mg of calcium, 27.1 mg of iron, and 14.5 mg of indium per 100 grams. The meat also offers therapeutic benefits, such as promoting blood circulation, detoxification, and reducing internal heat. It is especially beneficial for individuals suffering from conditions like spleen-stomach disorders, hepatitis, kidney weakness, impotence, coronary heart disease, hypertension, and arteriosclerosis.
For farmers interested in raising African geese, proper housing is essential. A traditional manor-style house can be used, while new structures should be built on flat, dry, well-ventilated, and sunny land with good drainage. Inside, there should be nesting areas, outdoor sports courts, and pools. Open-top nets should be installed to prevent escape.
Under artificial breeding conditions, Toona sinensis geese reach a weight of about 3 kg at 56 days old, growing to 5–6 kg by 84 days. The male-to-female ratio is typically 1:4. Females begin laying eggs at 150–180 days old, producing 120–150 eggs annually, with each egg weighing between 80–100 grams.
Egg incubation can be done using machines or hens. Before incubation, eggs must be disinfected with 0.2% potassium permanganate. The ideal temperature is 38°C, with humidity between 65% and 75%. Good ventilation is crucial to avoid bad hatchings. Eggs should be turned every two hours at a 90-degree angle. They should be candled 2–3 times daily for 10–30 minutes. The first candle occurs on day 9, and the second on day 21.
Sweet-shelled quail chicks take 35 days to hatch. Brooding starts at 34°C on the first day, decreasing by 0.5°C daily until they are fully acclimated. Humidity should be kept between 60% and 70%, and lighting should be continuous for the first 24 hours. The density should be around 20–25 birds per square meter during the first week, adjusting as they grow. Water should be given at 20–30°C, mixed with penicillin (2000 units per liter) after feeding. Chicks can start eating 2 hours later, with boiled rice or soaked feed sprinkled on plastic sheets to encourage consumption.
For chicks aged 0–6 weeks, the feed formula includes 56.5% corn, 15% soybean meal, 15% bran, 10% peanut meal, 2% bone meal, 1% shell powder, 0.4% salt, 0.1% additive, and some green feed. Feed them five times daily with free access to clean water.
From 6 to 10 weeks, the feed formula changes to 50% corn, 22% soybean meal, 20% bran, 4% fishmeal, 1.6% bone meal, 1.5% shellfish, 0.4% salt, 0.5% multi-dimensional additive, and trace elements. The protein content is about 17% per kilogram, with a metabolic energy level of 11.3 MJ.
During the egg-laying period, feed formulation should be adjusted based on peak production. Daily feed amounts range from 75g to 100g, with adequate green feed provided three times a day and free access to water.
Disease prevention is critical. Newborn goslings receive a subcutaneous injection of 0.5 ml of high-impact serum on day 2. On day 10, they get 1 ml of gosling fever vaccine. Adult females are vaccinated with a gosling attenuated vaccine 15–30 days before egg production to ensure healthy offspring.
