Polydactyly (toe) resection

Multi-finger (toe) is a common malformation that is second only to the finger and often refers to a deformity. It may be a partial deformity of some syndromes. More common thumb and more fingers, followed by a small finger. According to the multi-finger (toe) involving all or part of the finger. Treatment of diseases: congenital and refers to multi-finger malformation in children with retinitis pigmentosa - obesity - multi-fingery syndrome Indication Various types of multi-finger (toe) deformities Preoperative preparation 1. Identify and retain the primary finger from multiple fingers and remove the secondary surgery. 2. Enhance and enhance the retention of finger morphology and function from the components in the resected finger. 3. To avoid obstructing the development of the finger, it is decided to remove the multi-finger time. 4. Sometimes it is necessary to perform multiple operations to achieve the best morphological and functional results, and to design a staged surgery. Surgical procedure (a) i and ii type thumb multi-finger 1. The two types of multi-finger can be wedge-shaped resection on both sides of the center, that is, after the wedge-shaped resection of the nail, the fingerbone and the phalanx in the center of the multi-finger, the phalanx, the soft tissue and the nail are formed into one finger. This is a good method for handling such multi-finger at present, which can prevent the fingertip from being misaligned. This method is required to be performed after the end of the growth of the thumb, that is, after the age of 15. Preschool surgery requires attention to the function of retaining the fingers, that is, paying more attention to the preservation of the epiphysis and tendon. 2. If one of the two fingers refers to a large nail, the small nail is removed, and the lateral soft tissue is preserved and the side of the thumb is preserved. For example, the phalanx is biased to correct the wedge osteotomy. (ii) iii and iv type multiple fingers 1. The age of surgery is more than 3 years old after surgery, too early can cause dislocation due to the destruction of osteophytes, affecting joint activity, lateral instability and fingertips. 2. Surgical operation Incision was designed according to Fig. 4 (1) to (3), and the skin, subcutaneous and excised excess bone were cut. The collateral ligament, tendon and part of the skin tissue flap are retained. Use the retained collateral ligament and tendon to repair and stabilize the joint to prevent subsequent eccentricity. The skin incision is designed as far as possible on the back side. Postoperative Kirschner wire fixation for 6 to 8 weeks.
