Treatment of femoral shaft union disturbances with intramedullary nailing. Treatment failure.
BACKGROUND
The paper contains an analysis of the treatment outcomes of intramedullary nailing for femoral shaft non-union.


METHODS
Twenty-two patients were treated between 1999 and 2005 with locked intramedullary nailing for femoral shaft non-union. The average age was 38.2 years (range 17-79). The study group comprised 20 males and 2 females. The right femur was affected in 12 patients, and the left in 10 patients. All patients had undergone multiple operations to treat the non-union. At the time of the study, non-union had been present for a period ranging from 9 months to as much as 10 years. Stabilisation with an intramedullary nail was preceded by reaming of the medullary cavity. Nails of different diameter were used (11-16 mm, usually 11 or 13 mm). Both static and dynamic locking was used. Surgery was confined to stabilization with an intramedullary nail in 13 patients, and 9 patients additionally underwent the Judet-Forbes decortication procedure, bone grafting or internal plate fixation and osteomuscular decortication.


RESULTS
The non-union healed in 19 patients and was not achieved in the remaining 3. A detailed analysis was performed in 9 cases in which the bone union was not achieved despite reaming the medullary cavity, nailing and additional procedures, which did not lead to bone healing in 3 patients.


CONCLUSIONS
Despite being an acknowledged method of treatment for delayed union of long-bone shafts, intramedullary nailing following reaming of the medullary cavity did not result in bone healing in all of our patients and additional procedures were often required. Therefore, the use of this procedure for femoral shaft pseudoarthroses should be decided on a case-by-case basis.
