Depending on the method of implantation, there is often hardening, pigmentation changes and even scarring of the implant area after implantation, so it is necessary to start scar prevention as early as possible. As the saying goes, “prevention is better than cure”, my opinion is that scar prevention is far more recommended than scar treatment in terms of investment and efficacy. In the early postoperative period of hand implantation, pressure therapy should be started in time when the skin piece is well established, among which elastic bandage and elastic sleeve are more applied measures; when wearing elastic bandage (sleeve), functional exercises should be carried out gradually, including fist clenching, palm stretching, holding and other movements (functional exercises of other limbs and joints should also be carried out with reference); scar medication such as silicone cream should be applied daily after local hot compress, and the medication should be fully absorbed through massage. The medication should be fully absorbed through massage, 3-4 times a day. For hyperpigmentation, apply medications such as silicone cream. Usually, the prevention of scar proliferation is a long and tedious work, which usually lasts for 6-8 months, because the period of scar proliferation is more than 6 months long. With the prevention by the above methods, if the skin softness of the implant area increases, the itching disappears, and no significant thickening occurs, the medication can be gradually reduced, but the elastic sleeve should still be insisted on for a longer period of time.
