Pediatric tenosynovitis is most often secondary to bacterial infection following a localized puncture wound, and should be treated conservatively first, and surgery should only be considered when conservative treatment is ineffective. When pediatric tenosynovitis exists, conservative treatment can be carried out first, such as splint immobilization, when the pain is more obvious, the use of anti-inflammatory analgesic drugs to improve the improvement, such as ibuprofen, diclofenac sodium and so on. If necessary, glucocorticoid drugs can also be applied, such as prednisolone acetate. If conservative treatment is ineffective for a long period of time and the symptoms gradually worsen, surgical treatment can be considered, such as tenotomy and decompression, which can loosen the adhesion of the tendon sheaths and tendons, so that motor function can be gradually restored. During the treatment process, parents must follow the doctor’s instructions and safely administer medication to their children, and after the surgery, they should do a good job of post-surgical care, which is conducive to post-surgical recovery.
