Phalangeal fracture crossed kyphosis is more effective. Fracture of the phalanx is a common upper extremity fracture, which can present with symptoms such as swelling and pain in the finger, localized pressure and other symptomatic manifestations. If cross Kirschner pin treatment is taken, it usually does not penetrate the joint, which is beneficial for early postoperative activities, and at the same time, cross Kirschner pin treatment can be withdrawn when fracture healing exists after review. Crossed Kirschner pin treatment has strong and stable fixation, which is good for early functional exercise and can obtain better treatment results. Fractures of the phalanges should be worn in a brace in strict compliance with the doctor’s instructions and functional exercises should be carried out under the doctor’s supervision. Daily attention should be paid to regular monitoring, and when localized fever, pain, swelling and other uncomfortable symptoms occur, attention should be paid to timely consultation.
