Pediatric series consists of elastic nail,correction plate,pediatric proximal femoral locking plate,LC-DCP locking plate,reconstruction locking plste,T locking plate.
The special manifestations of pediatric fracture
(1) In children, soft tissue is loose, fascia is elastic, swelling after fracture is early, wide range, and often plaque.
(2) Pay attention to subperiosteal fracture, longitudinal percussion pain and local tenderness to consider the possibility of fracture.
(3) Children can be fever, generally below 38 degrees, caused by hematoma absorption.
(4) Identify the ossification center and epiphyseal plate, and add normal side control if necessary.
Characteristics of pediatric fracture repair
(1) The fracture heals quickly, and the younger the age, the faster the healing.
(2) The healing time of fracture is related to fracture site, fracture type, treatment method and individual situation.
(3) Joint stiffness occurred less.
(4) Have a certain shaping ability, the younger the age, the stronger the shaping ability, but the rotation deformity, the angular deformity inconsistent with the joint activity is more difficult to shape itself.
(5) Metaphyseal and shaft fractures due to hyperemia stimulate epiphyseal plate overgrowth, can cause temporary acceleration of limb growth, femur bone.It can overgrow by 0.8-2cm.
Principles of fracture treatment
The first is reduction, fixation, functional exercise. The principle is no longer to damage the epiphysis and epiphysis plate causing growth and development disorders. Manual reduction, plaster fixation, traction. Closed reduction and internal fixation. Open reduction, internal fixation (elastic needles, Kirschner needles, absorbable nails, absorption rods, various steel plates, external fixation brackets, hollow screws, etc.).

The first requirement is the site selection. The forest area should be at least 1,500 mu in size, with open drainage systems surrounding it and a secure escape prevention network installed to ensure the safety of the chickens.
Next, the chicken house facilities. In the open space within the forest, steel-frame sheds are constructed, covered with plastic film. Each shed has a width of 6 meters and a length of 50 meters. To maintain good air circulation, ventilation holes are placed every 10 meters, ensuring fresh air inside the structure.
Third, the selection of chickens. It is recommended to raise Luhe local chickens, which are known for their high quality, smaller size, lower fat content, and superior taste. Adult chickens typically weigh between 1.5 to 1.75 kg, making them ideal for feeding 3 to 5 people. These chickens are in high demand in the market due to their limited supply.
Fourth, main breeding techniques:
1. Rearing of young chicks: (1) For the first 2 weeks, the intake of feed is minimal, and the temperature should be maintained between 30-33°C. (2) From week 3 to 5, the feed should be enriched with higher protein content, and both feed and water should be available at all times. The temperature should gradually decrease by 0.5°C per day, while maintaining humidity at 50-55%. (3) Regular cleaning of the coop is essential to keep the air fresh, odor-free, and to prevent disease. The humidity should be kept between 55-60% during this period.
2. Feeding young chickens: Young chickens refer to those under 6 weeks old before they start laying eggs. They can be allowed to forage freely in the forest, where they can eat weeds and insects, improving their natural diet and enhancing meat flavor. In addition, they should be fed 2-3 times daily with balanced nutrition to support their growth.
3. Feeding during the laying period: During this phase, grass-fed chickens require more feed with higher nutritional value, especially in terms of protein, calcium, phosphorus, and vitamins. This helps improve egg production and overall health. It's important to remove low-producing hens promptly to reduce feed waste and increase efficiency.
Fifth, disease prevention and treatment: After vaccination, day-old chicks receive the V4 vaccine within 12 hours. Marek’s disease vaccine is administered in the breeding greenhouse, with a temperature maintained around 33°C. Erythromycin powder is used as the first antibiotic. Within one week, freeze-dried vaccines are given as nasal drops. A new bird couplet (500 bottles per bottle) is added to the drinking water and given once a week. No antibiotics should be used within 10 days after vaccination. At 5 weeks, the I strain vaccine is administered, and between 40-60 days, the H5N1 avian flu vaccine is injected. A second immunization is done after 120 days. Regular deworming is conducted, and vaccine antibody levels are monitored. Some medications are also added to the drinking water to prevent diseases. From day 2 to 7, 0.02% furazolidone and 0.01% oxytetracycline are added. These are repeated at 14-17 days. Chlorobenzene and anticoccidial drugs are included in the feed for deworming. Sick chickens are isolated, and treatments include antibiotic injections. Coops are cleaned daily, and lime is used for disinfection. Every 1.5 months, compound phenol is sprayed inside and outside the coops, and 100 toxins are used to sterilize the chickens.
