Due to the irregular characteristics of the pelvic structure, the choice of internal fixation is diverse.
For patients separated symphysis pubis, a 2 or 4 holes, 4.5 or 3.5mm diameter dynamic compression plate or reconstruction plate can be used and fixed with full-thread cancellous bone screws.Another method of fixation is lag screw fixation. In patients with new sacroiliac joint dislocation with a forward approach,firm fixation can be achieved by using 2holes 3.5mm dynamic compression plates through the front of the sacroiliac joint. The posterior approach can also be used to insert 6.5mm lag screws into the sacral wings or hollow cancellous bone screws with interosseous compression for firm internal fixation. If available, the fracture may be fixed with 3.5mm or 4.5mm pelvic reconstruction plates and appropriate full-thread cancellous bone screws.

Loach conservation techniques involve several key steps to ensure a healthy and productive environment for the fish. First, the construction of Jianchi ponds should be done in a location that is sheltered from the wind and receives ample sunlight. The pond must have a reliable water source, efficient drainage and irrigation systems, and no risk of water pollution. The ideal size of the pond ranges from 100 to 150 square meters, and it's best to divide it into smaller pools for easier management and to prevent disease spread. The depth of the pond should be between 1 and 1.2 meters. A drain outlet should be placed 30 cm above the bottom, and anti-escape measures must be installed. During winter, a plastic shed should be built to protect the loaches from cold weather.
Before stocking, proper preparation is essential. Two weeks prior to introducing loaches, the pond should be filled with 20 cm of mud and disinfected. After one week of disinfection, add 20–30 cm of water and incorporate livestock manure at a rate of 0.3–0.5 kg per square meter. Then, add another 40–50 cm of water. Loaches should be introduced only after the water turns yellow-green with a transparency of 15–25 cm, which usually takes a few days.
When stocking, select healthy, active, and disease-free loaches. Ensure that the size of the loaches in each pool is similar, and stock them all at once if possible. Before placing them in the pond, they should be immersed in a 2–4% saline solution for 10–15 minutes to sterilize them. The stocking density is generally around 25 kg per cubic meter of water. As the loaches grow, the water level can be increased to about 90 cm.
Effective management is crucial for successful loach farming. Feeding is an important aspect—loaches are omnivorous, consuming both animal and plant-based food such as small crustaceans, aquatic insects, snails, algae, rice bran, bean dregs, and leaves. A balanced diet is necessary, and feeding should be done at fixed times, places, and quantities. Avoid feeding when the water temperature exceeds 30°C or drops below 10°C.
Fertilization should also be part of the routine. Every 4–5 days, apply 50–100 grams of manure per square meter to maintain water clarity between 15–25 cm. Regular water changes are essential; change the water every 7 days twice, each time replacing 30 cm of water to prevent water quality degradation and reduce the risk of floating heads.
Disease prevention involves daily inspections of the pond, cleaning feeding areas, and applying bleaching powder every 10–15 days. This helps maintain a clean environment and prevents illness, ensuring the survival and health of the loaches.
