结果：康复组患者的功能改善明显较对照组为佳，两组患者总费用之间差异无显著性；不论是手关节TAM、手灵巧度，还是手精细运动功能评分每改善1分，康复组所耗费的相关成本费用明显较对照组为低，对照组相关费用约是康复组的1-2倍。

Results ①The mean value of wound healing time of group A, B and C was 10.4±1.0、17.8±1.6、11.4±1.3 days respectively.②The granulation of group A and C filled wound area at 4th～5th day after injury; The granulation of group B began to grow into the wound area under necrotic cartilage at 10th day after injury ③The mean value of elevating height of group A, B and C was 1.20±0.56、1.68±0.73、1.15±0.50 mm respectively. Conclusion Removing perichondrium and reserving cartilage results in big scar.
