The Küntscher nail has proved successful in the treatment of non-unions of the median third of the femur and lower leg after opening of the medullary cavity; in fact, this method is described in literature as the method of choice. It is based on the assumption that a sufficiently dimensioned intramedullary Küntscher nail together with the biological stimulative action of the bone meal, will result in a rapid osseous bridging of the non-union. This method has been successfully used in 128 cases even in non-unions which were close to the joint. Healing occurred in 92% of the cases. In about 11 cases it became necessary to perform a secondary operation. The high rate of infection, amounting to 12.4%, is relatively low compared with the very high rate of infective relapses following the first operation to achieve healing of the bone fractures.
经证实，在打开髓腔后，Küntscher髓内钉对于治疗股骨和小腿中段的骨不连是成功的；事实上，该方法在文献中被描述为首选方法。其依据的假设是，尺寸足够的Küntscher髓内钉与骨粉的生物刺激作用相结合，将导致骨不连快速实现骨桥接。该方法已成功应用于128例病例，甚至包括接近关节处的骨不连。92%的病例实现了愈合。约11例病例需要进行二次手术。感染率高达12.4%，与首次手术治疗骨折愈合后极高的感染复发率相比相对较低。
