The dimensions and healing of 93 consecutive below-knee stumps were studied and based on observations a standard formula of stump classification was constructed (and discussed at the ISPO Meeting in Bologna 1980). Muscular atrophy and redistribution of oedema caused a mean reduction of calculated arbitrary stump volume of about 7% during the first 12 post-operative weeks accompanied by a change in distal circumferential measurement ranging between 7 centimetres reduction and 5 centimetres increase. The classification formula was tested in 135 examinations in 86 patients with 96 stumps in Lund. A new proportional definition of stump length was used. Eighty per cent were ordinary in length and shape. Ten of 59 were conical before one year compared to 12 of 42 after more than one year following amputation. Pain was a problem in 20%. Scar problems are common early but other skin damage increases with time. Skin problems are separated according to cause, i.e. pressure, suction, infection and allergy. One third of below-knee stumps had unhealed wound or damaged skin. Surgical correction was indicated in 2% and prosthetic correction in 7%. Prosthetic correction seemed to be more often needed in below-knee stumps and surgical correction in above-knee stumps.
对连续93例膝下残肢的尺寸和愈合情况进行了研究，并根据观察结果构建了残肢分类的标准公式（并在1980年博洛尼亚的国际假肢与矫形器学会会议上进行了讨论）。在术后的前12周内，肌肉萎缩和水肿重新分布导致计算得出的任意残肢体积平均减少约7%，同时远端周径测量值的变化范围在减少7厘米至增加5厘米之间。该分类公式在隆德对86例患者的96个残肢进行的135次检查中进行了测试。采用了一种新的残肢长度比例定义。80%的残肢长度和形状正常。截肢后一年内，59个残肢中有10个呈圆锥形，而截肢一年以上后，42个残肢中有12个呈圆锥形。20%的患者存在疼痛问题。早期瘢痕问题很常见，但其他皮肤损伤会随着时间增加。皮肤问题根据病因分类，即压力、吸力、感染和过敏。三分之一的膝下残肢有未愈合的伤口或皮肤受损。2%的患者需要手术矫正，7%的患者需要假肢矫正。膝下残肢似乎更常需要假肢矫正，而上肢残肢则更常需要手术矫正。
