Abstract
One hundred and sixty-four cases of intramedullary nailing of the long bones have been studied with special reference to the difficulties and complications encountered.
There was one death not attributable to the method.
Two cases of pulmonal fat embolism and one case of thrombosis occurred, all in fractures of the femur.
The lessons we have learned from our mistakes can be summarised as follows:
1 . The method requires technical experience and knowledge and is not suited to inexperienced surgeons or surgeons with little fracture material at their disposal.
2. Intramedullary nailing should only be used in fractures to which the method is suited. In general, comminuted fractures or fractures near a joint are unsuitable.
3. Open reduction is preferable to closed methods.
4. The nail should never be driven in with violence. It should be removed and replaced with a new one if difficulty is encountered when inserting it.
5. In fractures of the femur the nail should be driven in from the tip of the trochanter after careful determination of the direction.
6. The nail should be introduced only to the level of the fracture before exploring and reducing the fracture.
7. Distraction of the fragments must be avoided.
8. If the nail bends it should be replaced by a new one, at least in femoral fractures.
9. If union is delayed, the fracture should be explored and chip grafts of cancellous bone placed around it.
10. Improvised nails or nails which are not made of absolutely reliable material should never be used.
11 . Make sure that the nail is equipped with an extraction hole for removal.
