One hundred and three consecutive patients who underwent Küntscher intramedullary nailing for recent non-pathological single fracture of the femoral shaft showed 13.6% incidence of non-union. The latter complication was not significantly influenced by the type, site, and cause of the fracture nor by sex, timing of the operation, and reaming of the medullary cavity. Conversely, non-union was more common in older patients and in those who were in bad general condition prior to and at the time of operation. Similarly, non-union increased significantly when the nail was too thin, or its lower end did not reach the optimum level (2 cm higher than the joint line), when weight-bearing was started 6 weeks or less after operation and in the presence of post-operative knee stiffness. Two patients presented with broken nails and four with angulated nails in the presence of non-union. Three patients with segmental fracture of the femur showed non-union of the fracture nearer to the middle of the shaft.
103例因近期股骨干非病理性单处骨折接受Küntscher髓内钉固定的连续患者中，骨不连发生率为13.6%。骨折类型、部位、原因，以及性别、手术时机和髓腔扩髓均对后一种并发症无显著影响。相反，骨不连在老年患者以及术前和手术时全身状况较差的患者中更为常见。同样，当髓内钉过细、其下端未达到最佳水平（比关节线高2 cm）、术后6周或更短时间开始负重以及存在术后膝关节僵硬时，骨不连显著增加。2例患者出现髓内钉断裂，4例在骨不连情况下出现钉成角。3例股骨节段性骨折患者显示骨折更靠近骨干中部处发生骨不连。
