The surgical approach to finger button deformity is anesthesia followed by tendon stress balancing and interphalangeal joint release, as well as Kirschner’s pin fixation in the extensor position. 1. Anesthesia: Finger button deformity is mainly performed by nerve block anesthesia, such as nerve anesthesia of the root of the finger. 2. Tendon stress balancing and interphalangeal joint release: after successful anesthesia, postoperative disinfection is carried out, followed by tendon stress balancing examination and treatment of the deformed area, so as to ensure the function of the joint in the later stages of mobility; subsequently, interphalangeal joint release is carried out, with the aim of correcting the deformity of the finger joints. 3. Kirschner’s needle extension fixation: after completing the treatment of tendon stress balance and interphalangeal joint release, Kirschner’s needle is used to pass through the finger bone from distal to proximal for finger extension fixation, so as to promote the recovery of joint capsule, ligament, and so on. The purpose of correcting the deformity is thus achieved.
