In a multicentric study, the data of 628 trochanteric fractures, two non- unions, and 18 pathologic or impending fractures treated by Gamma nail in 13 Italian traumatology services were collected and analyzed. In 70% of the patients weight bearing was allowed in the first postoperative week and 78% of the controlled patients returned to their pretrauma walking ability. Complications included intraoperative (1.4%) and postoperative (1.2%) shaft fractures, 'cut out' of the lag screw (2.6%), and nail failure (0.5%). There were no cases of infection. An analysis of complications showed that most of them were due to technical mistakes. The safest procedure is 2 mm diaphyseal overreaming, introduction of the nail without hammering, and distal locking; the lag screw should be placed in the lower part of the head of the femur.
