Results of the multicentric Italian experience on the Gamma nail: a report on 648 cases.

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.

Exostosis: development, evolution and relationship to malignant degeneration.

The authors report a study of 408 cases of exostosis (318 single and 90 multiple) from the records of the Tumour Centre of the Rizzoli Institute. Special attention was paid to the relationship with peripheral chondrosarcoma, 73 cases of which are also in the records of the Institute, and were separately studied. The authors conclude that it is impossible to determine the incidence of malignant transformation of solitary exostosis. The incidence of malignant transformation of multiple exostoses in the present case material was 13 per cent, but the true incidence would undoubtedly be higher if all patients were followed up for life.

The results of a multicenter Italian study on the use of the Gamma nail for the treatment of pertrochanteric and subtrochanteric fractures: a review of 1181 cases.

A total of 1147 pertrochanteric and subtrochanteric fractures, 10 delays in consolidation and non-union, 24 pathologic fractures and osteolysis with the risk of fracture, treated with a gamma nail in 17 Italian departments of traumatology, were collected. In 70% of the patients weight-bearing was allowed during the first week postsurgery; 77% of the patients followed-up recovered the same ability to walk that had preceded trauma. Complications included intraoperative (1.8%) and postoperative (1.1%) diaphyseal fractures, cephalic screw cut out (2.2%), and breakage of the nail (0.4%). There were two cases of infection (0.3%). Most of the complications were related to errors in technique. The safest procedure is constituted by the choice of a nail with a thinner caliber, 2 mm diaphyseal over-reaming, insertion of the nail without the use of a hammer, and distal locking; the cephalic screw must always be inserted in the lower portion of the femoral head.
