The authors have reviewed two of Kuntscher's principles relating to intramedullary nailing: the moment of elasticity of the nail should be close to the moment of elasticity of the bone and the suppression of rotation movements at the fracture site is due to locking of the nail by virtue of its elasticity. They have conducted an experimental study which does not confirm these views. They considered that rotary stability is due to muscle tone, the line of the fracture and the anchorage of the ends of the nail at the upper and lower end of the bone.
髓内钉的弹性矩应接近骨骼的弹性矩，骨折部位旋转运动的抑制是由于髓内钉凭借其弹性而锁定。他们进行了一项实验研究，但并未证实这些观点。他们认为旋转稳定性归因于肌肉张力、骨折线以及髓内钉两端在骨骼上下端的锚固。
