Orthopedic external fixation system
The screw orthopedic is inserted into the bone near the fracture, and the fracture is fixed with an external fixator assembled by a chuck and a nail rod.
Indications
open fracture, nonunion, closed fracture with extensive soft tissue injury, fracture with multiple trauma, osteotomy and correction.
The use of orthopaedic external fixators is currently a superior fracture fixation technique, filling the gap between cast and internal fixation. At the same time, orthopedic external fixator has the characteristics of simple fixation method, stable, reliable and effective, and does not limit the joint movement, can be early ambulation advantages. It can reduce the time for the operator and is more friendly to the user. The external fixator was used together with the bone traction needle. In terms of the classification of orthopedic external fixators, it is mainly divided into four types: orthofix type external fixation, ilizarov type external fixation, ao synthes type external fixation,combined external fixator and common external fixators.
The external fixators in orthopaedics was used for reduction (shortening and overlapping displacement were corrected first, then lateral and angular displacement were corrected, and finally rotational and separation displacement were corrected; If closed reduction is difficult, open reduction can be considered, but the separation of soft tissue and peeling of periosteum should be minimized.
The selection of the insertion site.According to the anatomical characteristics of the soft tissue at the insertion plane, the important nerves, vessels and tendons should be avoided; The ideal entry point is the part of the bone close to the subcutaneous, in a word, generally choose the skin and bone between the muscle soft tissue is the weakest point into the needle. The installation shall facilitate observation and control of soft tissue damage, and permit any surgery that may be required, such as repair and reconstruction, dressing change, skin grafting, or bone grafting." According to the location of the bone, different diameters of the threaded needle were selected. Removal was performed after completion of late treatment.

Feeding methods and techniques for raising pigs
In rural pig farming, some farmers lack proper knowledge of feeding techniques, leading to improper feeding practices and inefficient feed utilization. In some cases, this can even result in feed poisoning and unnecessary economic losses. To prevent such adverse outcomes, the following key feeding techniques are recommended:
1. Regular deworming, gastric lavage, and stomach stimulation are essential. Since pigs are prone to parasitic infections, it is important to deworm them regularly—usually every 3 to 4 months. Piglets between 2 to 4 months old require special attention. Gastric lavage and stomach stimulation help improve stomach motility and digestive capacity, thereby increasing feed absorption. On day one, administer either 8 mg/kg of levofloxacin hydrochloride tablets or 2 trichlorfon tablets per 10 kg of body weight, crushed and mixed into the evening meal. On day three, give 15 grams of baking soda (adjusted for piglets) with breakfast. On day five, feed two rhubarb soda tablets per 10 kg of body weight, divided into three meals.
2. Feeding should be both regular and portion-controlled. Establish a consistent feeding schedule—such as at 6 AM, 11 AM, 4 PM, and 9 PM—to help pigs develop a routine and promote better digestion. Feeding at fixed times helps stimulate digestive juices and increase appetite. Portion control is also crucial—feed about 80-90% of the daily ration each time to keep pigs hungry and eager to eat.
3. Gradual feed transitions are necessary when changing feed types. Sudden changes can cause digestive issues and reduce feed intake. When switching from raw to cooked feed, gradually increase the proportion of new feed over several days to allow the pigs to adapt.
4. Dry and wet feeding methods are more effective than dry-only or overly wet feeding. Dry feeding requires more saliva and gastric juice, while wet feeding may lead to excessive water consumption, diluting digestive enzymes and reducing nutrient absorption. The ideal ratio is 1:1 (feed to water), ensuring optimal digestion and faster growth.
5. Certain feeds like beans, potatoes, taro, and pumpkins should be cooked or fried before feeding to avoid poisoning. Other feeds should be kept raw to preserve nutrients and save energy.
6. Compound feed must be clean, high-quality, and free from spoilage, clumping, or debris. Coarse roughage should be finely chopped for easier chewing and digestion.
7. Green feed should be washed, dried, and either fed whole or chopped and mixed into compound feed. This ensures better nutrient intake and palatability.
8. Provide clean drinking water at all times. Installing automatic drinkers or separate water bowls ensures pigs have access to fresh, uncontaminated water, which is vital for their health and growth.
By following these practices, farmers can significantly improve feed efficiency, reduce health risks, and enhance overall productivity in pig farming.
