Abstract
We report our experience using an inflatable intramedullary nail in 20 diaphyseal humeral fractures. The nail is introduced without reaming and does not require proximal and distal locking, because it allows radial stabilisation of the fracture. The tip of the nail must be inserted 5 cm beyond the fracture line.
Since April 2002 we have applied 20 “Fixion” nails in 19 patients with humeral fractures. This is a stainless steel nail with a circular cross section reinforced by four bars, which can be inflated by saline solution through a dedicated pump. The average age of the 19 patients was 35.6 years, 15 were males and four female. Among these, 17 were closed fractures, three fractures open degree 1 (Gustilo Anderson class.). According to the AO classification, eight fractures were type A1 and A2, 10 were type A3 and two type B2. Nine fractures required reaming. Passive mobilisation is allowed 5 days after surgery, followed by active mobilisation 3 weeks later.
Eighteen of the twenty fractures consolidated in an average time of 3.5 months. Two of 20 cases showed delayed union at 4 weeks and were treated by increasing the immobilisation period. Final healing without complications in these cases was observed at 5 months. No peripheral neurological complications were observed.
“Fixion” nail is a new, easy method of intramedullary nailing. It helps to reduce operating time and in our experience it did not show any complications. It must be reserved for simple diaphyseal fractures where it is possible to achieve good stability and complete union.
