Regardless of the type of polydactyly, surgery is the only way to solve the problem. However, not everything is fine after surgery. Post-operative wound care and blood circulation to the affected finger are the keys to ensure the success of the surgery. Do I need to change the medication after polydactyly surgery? For polydactyly surgery, if no osteotomy is done, it is enough to wrap the wound with a bandage in the figure 8 method after surgery to keep it clean and dry. Generally, the doctor will change the medication once in 5 days after the surgery to observe the wound condition, and the stitches can be removed in 2 weeks after the surgery if there is no special condition. Before the removal of the stitches do not need to change the medication again, of course, if the child accidentally soiled or wet bandage, or need to deal with. If the child has had an osteotomy, a kyphotic pin will be threaded through the finger and the surgeon will use a palm rest and bandage to hold the child’s hand in place after surgery. The stitches are usually changed at the time of removal two weeks after surgery to observe the healing process; if needed, a more appropriate palm brace is also replaced and immobilization continues for 3 to 4 weeks. The kleenex needle exposed outside the finger should be disinfected regularly and wiped once a day with an iodophor cotton ball to avoid infection of the needle hole, which is usually able to be pulled out after 3~4 weeks. Observe the color of the finger, turn white and purple are not allowed! After surgery for polydactyly, parents need to focus on whether the child’s wound is bleeding, and blood circulation is good. Generally, the wound will not bleed after surgery because a tourniquet will be used to stop the bleeding, and pressure bandages will be applied after the surgery. If there is bleeding, most of it is because the bandage is too loose and not pressing the wound, so re-bandage it. It is very important for parents to observe the color of their child’s finger after surgery. If the color of the finger turns white or purple, it means that the blood circulation is not good. A purple finger means that the venous return is blocked, while a white finger means that the artery is compressed and the finger is ischemic. In this case, the bandage needs to be opened immediately and then rewrapped after the finger color has changed to normal. Is it normal for the affected finger to swell after surgery? In general, the swelling of the affected finger after polydactyly surgery is due to the irritation of the surgery, not because it was not cut cleanly, and will subside in about four weeks after surgery. However, some swelling does not subside and is intentional – the surgeon removes the polydactyly but preserves the tendons of the polydactyly. Because the preserved finger is usually less developed, leaving the tendon attached to the affected finger can increase the muscle strength of the affected finger. Although the affected finger looks swollen, as the child grows and develops, both fingers will become more and more symmetrical and will recover in about 2 to 3 years, similar to normal fingers.
