Partial resection of finger soft tissue and digital nerve

Finger soft tissue and partial nerve resection for surgical treatment of congenital giant finger deformity. Congenital giant finger deformity is rare, more male than female, most of the cases are seen when a certain finger is obviously thick, and a few days after birth, it is found that the growth of the finger is faster than normal. Although the giant finger deformity can occur on every finger, the middle finger and the index finger are the most common. It is generally believed that neurological abnormalities are the cause of the abnormality of the giant finger. The treatment of this deformity is quite difficult. The main surgical methods include soft tissue, partial finger nerve resection and finger shortening of finger bone and soft tissue resection. The former applies to young children and the latter applies to older children or adolescents. However, the effect of each operation is not very accurate, and it is necessary to divide the operation. Curing disease: Indication Partial soft tissue and finger nerve resection are suitable for congenital giant finger deformity. It is observed that the growth rate is not very rapid, and the deformity of the finger is not very serious. The child is 3 to 5 years old. Contraindications Take X-ray films to see if the phalanx and metacarpal bones have obvious thickening and other abnormalities. Each of the giant finger deformities must be divided into two parts to complete the soft tissue and partial resection of the finger nerve. In this regard, both the surgeon and the parents should have sufficient mental preparation. The interval between the two operations takes about 3 months to ensure that the fingers do not have blood supply disorders. Surgical procedure 1. Excision of skin and subcutaneous fat tissue on one side of the giant finger The side incision of the finger is exposed, and according to the thickening of the giant finger, a long strip of skin and subcutaneous fat tissue on the side of the finger are removed. If the nail is obviously enlarged, it can also be partially removed. 2, the removal of part of the nerve Cut off the thick adipose tissue in the same incision, separate the finger nerve and the finger artery, and try not to damage the latter. It can be seen that the nerves are obviously thickened, and the outer membrane is thickened and dull. The nerve branches are thickened and hardened, and the fat tissue at the distal end is wrapped in a string. The finger nerve branches should be removed together with the adipose tissue. If the main trunk of the nerve is thickened, it can be opened and some nerve fiber bundles removed. 3, closed the incision Thoroughly stop bleeding and suture the skin in a full layer without tension. complication 1. Due to the removal of the branch of the finger nerve or part of the trunk, there is obvious pain and loss of physical sense in the early postoperative period. But it will gradually recover. 2, giant finger deformity recurrence, which may be related to surgical removal of diseased tissue. It is often necessary to perform multiple operations, or to perform corrections for tarsal block and bone shortening at the same time.
